Program Manual v 18.1 INTRODUCTION

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION II - 7 -

1 INTRODUCTION

Overview The 2018 C&I Standard Offer Program was developed by CenterPoint Energy to provide

incentives for the installation of a wide range of measures that reduce peak demand and save

energy in non-residential facilities and go above and beyond the efficiency gains typically

achieved in retrofit or replacement projects. Consequently, energy and demand savings credit

will be based only on reductions that exceed current industry accepted minimum efficiency

standards, if such standards apply. In cases where standards do not exist, savings credit will be

based on improvements relative to a customer’s energy use prior to participating in the program.

Incentives are paid based on deemed savings or verified demand and energy savings that occur at

CenterPoint Energy’s C&I customers’ facilities. This program has been developed to comply

with Texas’ Texas’ energy efficiency goals as outlined by the Public Utility Commission of

Texas (PUCT) Substantive Rule §25.181. Participants in the 2018 C&I Standard Offer Program

must meet the eligibility criteria, read this manual, comply with all program rules and

procedures, and enter into a Standard Agreement with CenterPoint Energy.

Background In 1999, the Texas Legislature passed Senate Bill 7 (SB7), which restructures the state's electric

utility industry. The bill requires each investor-owned electric utility to reduce Texas customers'

energy consumption by a minimum of 10% of the utility's annual growth in demand each year.

Utilities must achieve this goal through standard offer programs or limited target market

transformation programs that will result in reduced energy consumption. In March of 2000, the

PUCT passed Substantive Rule §25.181, which implements the energy efficiency goal of SB7.

Interested parties, the state's investor-owned utilities, and PUCT staff then developed templates

for energy efficiency programs that were adopted and are now offered and administered

throughout Texas by the investor-owned utilities. In September of 2007, House Bill 3693 set

new Energy Efficiency Goals for electric utilities in Texas. The bill requires each investor-owned

electric utility to reduce Texas customers' energy consumption by a minimum of 30% of the

utility's annual growth in 2014. Utilities must achieve this goal through standard offer programs

or limited target market transformation programs that will result in reduced energy consumption.

Goals The main goal of the C&I Standard Offer Program is to reduce peak demand at CenterPoint

Energy’s distribution customer sites and reach the demand reduction goals established by Senate

Bill 1125. Secondary program goals that are reflected herein, include:

Encourage private sector delivery of energy efficiency products and services.

2 GUIDELINES

Key Changes for 2018 CenterPoint Energy strives to adhere to all rules and regulations established in the Technical

Resource Manual (TRM) as administered by the PUCT. In line with this effort, CenterPoint

Energy reviews its Energy Efficiency Programs and evaluates general program recommendations

annually. The outcome of this review may result in periodic updates to this manual.

It is the responsibility of the Sponsor to read the 2018 C&I Standard Offer Program Manual

in its entirety and to fully understand changes from the previous year’s program.

For your convenience, key changes reflected throughout were compiled in this section and

include:

Option to pay the required deposit electronically

Any commercial and industrial customer taking service at a metered point of delivery at a

distribution voltage (<69 kVA) under an electric utility’s tariff during the prior calendar year

or

A non-profit customer or

A government entity or

An educational institution

Large Commercial Customer: Owns or operates a single site with a total maximum peak

demand of more than 100 kW or multiple sites with a combined maximum peak demand

greater than 250 kW

Small Commercial Customer: Owns or operates a single site with a total maximum peak

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION II - 11 -

Sponsor’s acceptance for participation or continuation in the 2018 C&I Standard Offer Program.

For more information regarding Sponsor Evaluation see section 2.4.4.

2.2.2 Project

A project is defined as a set of proposed or installed measures at an eligible site or combination

of sites. For a site to be eligible for a project, Sponsors must be able to provide reasonable access

to project facilities for inspection before and during installation and after project completion. All

projects must meet the following requirements:

For Large Commercial and Multifamily customers, each project of one site must provide a

total estimated peak demand reduction of at least 15 kW or annual energy savings of at least

100,000 kWh, and each project of multiple sites must provide at total estimated peak demand

reduction of at least 30 kW or annual energy savings of at least 200,000 kWh. This

limitation is included to ensure that projects contribute to the primary program goal of

reducing peak demand and to minimize the administrative costs associated with smaller

projects.

Multifamily/Strip Center customers are not subject to the 5 site per project

recommendation and are required to submit each ESI which will reduce load as a part of

the submitted project. All the ESI/addresses should coincide with a single physical site.

If the measures and sites proposed are all similar, one project may involve the

installation of measures at multiple customer sites, recommend no more than5 sites.

For example, installation of measures at a chain of department stores may include

more than one customer site, but may constitute a single project. These sites would

share a common M&V plan. All sites and measures must be installed before the first

payment will be made. There are advantages and disadvantages to bundling project

sites in this manner. Contact the program administrator with detailed questions.

For projects with incentives paid based on verified demand and energy savings, peak

demand savings must be measured within the peak demand period. M&V of energy

savings may continue for up to 12 months and carry into the following year.

New construction projects must demonstrate compliance with local, state or federal codes,

whichever is more stringent. Projects using the Energy Cost Budget Method to demonstrate

code compliance will be considered for program participation on a case-by-case basis.

Projects for Small Commercial customers are expected to have a reduced scope of work. As

such, the participation requirements in the program are simpler and outlined in this section.

Small commercial projects:

Must include facilities with a maximum peak demand of less than 100 kW (or 250 kW

combined for multiple sites in the same project).

Each project must provide a total estimated peak demand reduction of up to 15 kW or

100,000 kWh

Do not have a minimum savings requirement.

Are required to submit a deposit of $250 per project/site.

Are limited to deemed savings calculations only.

Require Sponsors to answer CenterPoint Energy inquiries in a timely manner, 10 days or

less. Failure to respond within the time period may result in cancellation of the project.

Must complete project within 45 days of the PA approval date or final program year

installation date, whichever comes first.

One site per project.

2.2.3 Measure

Most energy-efficiency measures in retrofit or new construction applications that reduce electric

energy consumption and peak demand are eligible for the C&I Standard Offer Program.

CenterPoint Energy does not specify eligible measures in order to provide Project Sponsors

flexibility in packaging services. Therefore, Project Sponsors may propose the inclusion of any

measure in their project that meets the following requirements:

Measure may produce a measurable and verifiable electric demand reduction during the peak

period(s) or may reduce electricity consumption, or may produce both peak demand and

energy savings.

Measure must produce savings through an increase in energy efficiency or a substitution of

another energy source for electricity supplied through the transmission and distribution grid.

Measure must exceed minimum equipment standards as established in the Program Manual

(located in manual Appendices).

Measures may provide for self-generation using renewable technologies, such as:

Solar

Wind

Geothermal

Hydroelectric

Wave/tidal

Biomass

At least 75% occupancy ratio of the building is required.

Projects involving combined heat and power (CHP) will be reviewed on a case-by-case basis

for qualification by CenterPoint Energy. In general, project incentives will be paid only for

energy and demand savings directly related to end-use equipment installed as part of the

project. Measures that generate savings from interactive effects between end-use equipment

will be considered on a case-by-case basis. The exception is that savings due to interactive

effects between lighting and a space-cooling measure are eligible based on a stipulated value

in cases where lighting measures have been installed in a cooled space as part of the project.

2.2.4 Efficiency Standards

The C&I Standard Offer Program is designed to encourage electric energy-efficiency

improvements that go above and beyond the efficiency gains typically achieved in retrofit or

replacement projects. Consequently, energy and demand savings credit will be based only on

reductions that exceed current industry accepted minimum efficiency standards, if such standards

apply. In cases where standards do not exist, savings credit will be based on improvements

relative to a customer’s energy use prior to participating in the program.

2.3.2 Incentive Limitations

Maximum Sponsor Incentives

To ensure that incentives are available to multiple energy efficiency service providers, no Project

Sponsor, or combination of affiliated Project Sponsors, may reserve or receive more than 20% of

the total C&I Standard Offer Program incentive budget in a given budget year. An individual

Project Sponsor may be party to multiple applications if the total incentive from all such

applications does not exceed the 20% limit.

Maximum Project Incentives

All projects will require a copy of the final installation invoice. No project will be incentivized

more than 50% of installed cost. Invoices submitted to the C&I Standard Offer Program must

split out the material and labor amounts.

2.3.3 Payments

For projects using only deemed savings, requiring no M&V activities beyond installation, the

Project Sponsor is eligible to receive 100% of the project incentive payment after the project is

installed and approved by CenterPoint Energy. For all other projects, M&V activities must be

completed, documented, and accepted before the Project Sponsor will receive the remaining

incentive payment, based on the one-year verified savings. CenterPoint Energy will pay the

Project Sponsors in two installments: The Installation Payment and the Performance Payment.

After each project is installed and approved by CenterPoint Energy, the Project Sponsor will

receive an initial payment of 40% of the total estimated project incentive payment. This initial

“Installation Payment” will be calculated as follows:

1 Whole fixture replacements only. Screw-in LED lamps do not qualify for incentives.

Page 17: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 GUIDELINES

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION II - 17 -

𝐼𝑛𝑠𝑡𝑎𝑙𝑙𝑎𝑡𝑖𝑜𝑛 𝑃𝑎𝑦𝑚𝑒𝑛𝑡 ($) = 40% × [(𝑘𝑊𝑠𝑎𝑣𝑒𝑑 × $/𝑘𝑊) + (𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 × $/𝑘𝑊ℎ)]

This “Performance Payment” may be up to 60% of the total estimated incentive payment, and

will be calculated as follows:

𝑃𝑒𝑟𝑓𝑜𝑟𝑚𝑎𝑛𝑐𝑒 𝑃𝑎𝑦𝑚𝑒𝑛𝑡 ($)

= 60% × [(𝑘𝑊𝒔𝒂𝒗𝒆𝒅,𝒗𝒆𝒓𝒊𝒇𝒊𝒆𝒅 × $/𝑘𝑊) + (𝑘𝑊ℎ𝒔𝒂𝒗𝒆𝒅,𝒗𝒆𝒓𝒊𝒇𝒊𝒆𝒅 × $/𝑘𝑊ℎ)]

− 𝐼𝑛𝑠𝑡𝑎𝑙𝑙𝑎𝑡𝑖𝑜𝑛 𝑃𝑎𝑦𝑚𝑒𝑛𝑡

Maximum incentive payment

Under no circumstances will CenterPoint Energy make a total incentive payment (i.e., the sum of

the Installation Payment and the Performance Payment) that is more than 100% of the total

estimated incentive payment specified in the Project Authorization, regardless of measured

savings achieved. If, however, M&V activities indicate that the measured savings are less than

the estimated savings, the total incentive payment will be less than the payment estimated in the

Project Authorization.

𝑃𝑒𝑟𝑓𝑜𝑟𝑚𝑎𝑛𝑐𝑒 𝑃𝑎𝑦𝑚𝑒𝑛𝑡 ($) + 𝐼𝑛𝑠𝑡𝑎𝑙𝑙𝑎𝑡𝑖𝑜𝑛 𝑃𝑎𝑦𝑚𝑒𝑛𝑡 ($)≤ 100% 𝑜𝑓 𝑃𝑟𝑜𝑗𝑒𝑐𝑡 𝐴𝑢𝑡ℎ𝑜𝑟𝑖𝑧𝑎𝑡𝑖𝑜𝑛 𝐿𝑖𝑚𝑖𝑡($)

For more information on the Project Authorization, see section 3.2.6.

Deposits

To demonstrate a commitment to fulfilling program objectives and ensure that the program’s

incentive budget is allocated to projects that are likely to meet with success, an application

deposit is required. A project will neither be reviewed nor considered for incentive funding

until after a deposit has been received. The required application deposit amounts are as

follows:

Large and Multifamily Commercial: 5% of requested incentive

Small Commercial: $250 per project application/single site

Project deposits are refunded 100% for projects that meet 75% of their approved Project

Application(PA) incentive goal. For more information on application deposits, see section 3.2.5.

2.3.4 Fuel Switching Measures

Projects involving fuel switching measures require special consideration when calculating

incentives. Projects involving fuel switching (i.e., electric chillers to gas or absorption chillers)

are eligible for the program, provided the project results in overall lower energy costs, lower

energy consumption, and the installation of high-efficiency equipment. Incentive payments will

be based on the electric demand savings and energy savings of the project, adjusted by the

amount of new fuel consumption. Refer to the M&V Guidelines, Section III, Chapter 6, to

determine how to calculate fuel switching demand and energy savings. For all fuel switching

projects, it will be the responsibility of the Project Sponsor to establish the baselines, which must

be approved by CenterPoint Energy, and will be considered on a case by case basis. As noted,

fuel switching to electric is not an eligible retrofit measure.

Program Compliance

Project Sponsors are expected to understand and adhere to the C&I Standard Offer Program rules

as outlined herein. Should a Project Sponsor repeatedly demonstrate a poor understanding of

these rules by failing to adhere to them, this may, at CNP’s discretion, result in reduction of

estimated incentives, forfeiture of the deposit, project cancellation, and/or suspension from the

program. Suspension could span the program year or remain permanent.

2.4.1 Communication Standards

It is CenterPoint Energy’s priority to maintain open communication with Program Sponsors

participating in its Energy Efficiency Programs. To maintain accurate contact information, and

timely and effective communication, CenterPoint developed the following Communication

Standards:

CenterPoint Energy will conduct correspondence only with representatives from the Project

Sponsor’s organization listed in the Standard Offer Purchase Agreement

A representative of the Project Sponsor must register as the primary contact in the online

database system eTrack.

Recommend no more than 5 representatives per company may have logins in the eTrack

website

Absolutely no third-party companies will act as an intermediary for correspondence between

CenterPoint Energy and the Project Sponsor

Require Small Commercial Sponsors to answer CenterPoint Energy inquiries in a timely

manner, 10 days or less. Failure to respond within the time period may result in cancellation

of the project.

If a project falls outside of program guidelines, a formal request outlining the reason for the

exemption must be submitted and approved by the Energy Efficiency and Business

Development Director.

2.4.2 Correspondence and Submittals

Project Sponsors will submit most project information to CenterPoint Energy using eTrack, the

Web-based project application system. Some required submittals must only be sent to

CenterPoint Energy in hard copy, and are typically collected by an inspector at the time of final

site inspection. Questions or comments about the program may also be submitted by e-mail to

the Program Manager. See Table 6 below.

2.4.4 Project Sponsor Evaluation

As a participant in the C&I Standard Offer Program, Project Sponsors agree to perform

exceptional work to meet the goals of the program. To maintain exceptional projects,

CenterPoint Energy will evaluate each project by reviewing project submissions and progress

and provide feedback to the Project Sponsor. The evaluation will be based on the following:

Acceptable:

Quality issues in the initial submission are within allowances

Inspections find less than 10% difference between reported and actual equipment

All installed equipment meets efficiency standards

No differences between equipment cut sheets given to CenterPoint Energy and installed

equipment

Installation commences within timeframe given in the PA approval letter

CenterPoint Energy is notified about the start of installation 48 hours in advance

Needs Improvement:

Quality issues in the initial submission are above allowances

Inspections find greater than 10% difference between reported and actual equipment

Installed equipment does not meet efficiency standards

Noted differences between approved equipment (submitted cut sheets) and installed

equipment

CenterPoint Energy is not notified of installation start date/time via eTrack

Satisfactory Project Sponsor performance will be defined according to the number of ‘Needs

Improvement’ ratings—no more than 3 will be allowed within the same program year. If the

maximum number of allowed ‘Needs Improvement’ ratings is exceeded, the Project

Sponsor will be suspended from program participation. Permission to resume participation

in the program may be given at the sole discretion of CenterPoint Energy. If the Sponsor would

like to resume participation, CenterPoint Energy advises the Sponsor to review the program

requirements and communicates those requirements within its company, and to its sub-

contractors, submits a written request for consideration for reentry into the program to the

Program Manager. This request should indicate that the Sponsor understands the reasons for the

suspension, and the measures taken to avoid reoccurrence on future projects. If a project falls

outside of program guidelines, a formal request outlining the reason for the exemption must be

submitted and approved by the Energy Efficiency and Business Development Director. A

sample of issues and actions are presented in Table 7.

including the anticipated project timeline.

An agreement between the Project Sponsor and Customer, signed by both parties, must be

submitted as part of the Project Application (PAF, see Appendix C).

After compiling and uploading all the necessary documentation required completing a Project

Application, the Program Sponsor may submit the application. Though a project has been

submitted, CenterPoint will not review a project until a deposit has been received by CenterPoint

Energy.

3.2.5 Deposit

To demonstrate a commitment to fulfilling program objectives and ensure that the program’s

incentive budget is allocated to projects that are likely to meet with success, an application

deposit is required. A project will neither be reviewed nor considered for incentive funding

until after a deposit has been received. The required deposit amounts are as follows:

Large Commercial and Multifamily: 5% of Project Application incentive estimate in eTrack

Small Commercial: $250 per project application/single site

Any discrepancy to the required deposit, must be approved by the Program Manager. The

deposit may be sent electronically or in the form of a check or money order. Any and all

transaction fees associated with making an electronic payment will be assumed by the

Sponsor and should NOT be deducted from the deposit amount.

Mailed deposits will require:

Noted Project ID as provided by eTrack

For more instructions on how to submit Electronic Deposits see Appendix F. For a copy of the

Electronic Deposit Notification Form see Appendix F.

If program incentives are fully reserved when the deposit is submitted, the project will be placed

on a waitlist in the order of when the deposit was submitted in eTrack. When additional program

incentives become available, projects on the waitlist will be reviewed and activated in order.

Starting installation on a waitlisted project before it has been activated, will automatically

disqualify the project from receiving program incentives.

Deposit Refunds

The deposit is refundable to the CenterPoint Energy Purchase Agreement Holder upon approval

of the Savings Report, provided the project achieves a minimum percentage of the agreed

savings. Any modifications to the project will not affect the deposit, provided those changes are

made within 14 days of submittal. Deposit refunds are subject to the following shown in Table 8:

Table 8. Application Deposit Refund

Percent of Estimated Incentive

Payment Received

Percent of Deposit

Refunded

75%+ 100%

50%-74.9% 50%

0%-49.9% 0%

In the event that the Program is sold out, the project will be placed on the waitlist, with

submitted deposit. Remaining projects on hold after the incentive budget has been fully

committed will have deposits immediately refunded in full to the Sponsor.

3.2.6 CenterPoint Energy Project Application Review

Upon receiving a deposit for a completed Project Application, the Project Application will be

reviewed on a first-come, first-served basis until all incentive funding has been committed.

CenterPoint Energy will review the eligibility of the proposed measures, the accuracy of the

savings estimates, and the comprehensiveness of the M&V plan. CenterPoint Energy may

request clarification of, or additional information about any item in the application. Project

Sponsors will have ten business days to respond to such requests. If the clarification or additional

information is not forthcoming, CenterPoint Energy may choose to discontinue its evaluation of

the application and reject the project. As part of the Project Application review process,

CenterPoint Energy may, at its discretion, conduct a Pre-Installation Inspection of the project site

to verify the accuracy of the baseline conditions documented in the Project Application. Upon

Project Application approval (PA), CenterPoint Energy will reserve the appropriate amount of

incentive funds for the project and prepare a PA letter outlining the terms of the project. At this

same time, the Project Authorization Form (PAF) is generated for signatures.

CenterPoint Energy SECTION II - 27 -

3.2.7 Project Authorization

Once the PA has been approved, the customer shall receive a Project Authorization Form (PAF).

The PAF defines the specifics of the project, including measures to be installed, proposed project

installation schedule, and estimated incentive amount. The Project Sponsor, site representative

(end user) will received copies for authorized signature. Both parties must sign and return the

PAF to CenterPoint Energy before the project installation is complete. Failure to return the

signed form by both parties will result in forfeiture of project incentives.

3.2.8 Scheduling and Installation Notice

To ensure that projects are completed in a timely manner, CenterPoint enforces timelines to

complete the installation of a project post Project Application approval. Unless an alternative

construction schedule has been submitted by the Project Sponsor and approved by CenterPoint

Energy, project installation and the generation of the Installation Report (IR) must be completed

within:

Three (3) months for lighting-only projects for Large/Multifamily/Strip Center customers

Six (6) months for all other projects in Large/Multifamily and Strip Center

Forty-Five (45) days for Small Commercial customers

Project Sponsors should plan to reach 100% completion on all projects no later than December

1, 2018. For more information on the IR, see section 3.2.11.

Project Sponsors must use the eTrack work schedule to notify CenterPoint a minimum of 48

hours prior to the date the installation will commence. This allows CenterPoint time to schedule

resources for the installation inspection. CenterPoint will use the required eTrack work schedule

to contact the Project Sponsor and complete the inspection.

Failure to notify using eTrack will result in the cancellation of the project and the forfeiture

of the project deposit.

At its discretion, CenterPoint may conduct an onsite inspection during the 48-hours post

notification. CenterPoint will inform the Project Sponsor if such an inspection will take place.

Access to current equipment, new materials, installation crew and installation equipment should

be onsite and ready for CenterPoint Energy inspection. (If the schedule should change, Project

Sponsor is required to notify Program Manager no later than 7am on scheduled date to avoid

inspection fees) Projects must not start installation until CenterPoint is onsite. Failure to

comply could result in project cancellation.

3.2.9 Installation Inspection

A CenterPoint Energy Inspector may be present at the commencement of project installation to

conduct the Installation Inspection. CenterPoint Energy Inspectors are present to observe and

record only. The inspection team makes no judgement on installation practices or guidelines.

If the proposed equipment has been installed before the pre or installation inspection is

scheduled, the Project will be cancelled and will not qualify for the incentive. The installation

CenterPoint Energy SECTION II - 28 -

inspection also requires the presence of at least one representative of the Project Sponsor who is

familiar with the project and the facility so that all parties can identify any discrepancies.

For lighting only projects, CenterPoint requires that new materials necessary to complete the job

be onsite. The inspection will verify the following information:

Equipment survey accuracy.

For most measures, the inspector verifies the accuracy of the baseline equipment quantity and

nameplate information.

For lighting measures, a statistically significant sample size will be selected for the

inspection. Variables used in determining the sample include a Sponsor confidence factor,

number of sites in the project, and line item values submitted on the survey.

The requirement for acceptance is that the total error of the installed demand of the sample

must be within 10 % of the total demand submitted on the survey form. Errors greater than

10 % will result in a $1,000 fee for Large/Multifamily/Strip Center Commercial projects or

$250 fee for Small Commercial projects.

M&V plan appropriateness for the measure, and performance of any necessary M&V

activities.

All existing equipment listed in the Project Application is still in place and operational.

New equipment installation, or preparation for installation, has not begun.

If electrical measurements are necessary, the Project Sponsor is required to perform any

disruptions in equipment operation, the opening of any electrical connection boxes, or the

connection of current and power transducers. If the inspection cannot be completed in a timely

manner because the representative(s) is unfamiliar with the facility or project, the project site

will, at CenterPoint’s discretion, fail the inspection. If a project site fails the initial inspection,

and the Project Sponsor would like to continue participation in the program, and eligibility for

incentive, the Project Sponsor must schedule and pay the cost incurred by CenterPoint Energy

for any subsequent inspections.

Measures must be installed according to the manufacturer’s specifications. CenterPoint

Energy will cancel any project whose installation fails to meet this requirement.

Upon 100% completion of the project installation, Project Sponsors must update the project

status in eTrack to “Installation Complete”.

3.2.10 Post-Installation Inspection

CenterPoint Energy will conduct a post-installation inspection of the project site within 30 days

of the “Complete” status update in eTrack, where applicable. The post-installation inspection

should not be scheduled via eTrack, but by the CNP inspection team, and recommends the

presence of at least one representative of the Project Sponsor who is familiar with the project and

the facility. The Post-Installation Inspection shall verify that:

The equipment specified in the project application has been installed and is operating as

described.

For most measures, the inspector verifies the accuracy of the equipment quantity and

nameplate information.

For lighting measures, the inspection sample is determined using the same concept as the

pre-inspection methodology.

Requirement for acceptance is that the total error of the installed demand of the sample

must be within 10 % of the total demand submitted on the survey form. Errors greater

than 10 % will result in a $1,000 fee for Large/Multifamily and Strip Center

Commercial projects or a $250 fee for Small Commercial projects.

The Project Sponsor is conducting the M&V activities in accordance with the approved

M&V Plan.

If electrical measurements are necessary, the Project Sponsor is required to perform any

disruptions in equipment operation, the opening of any electrical connection boxes, or the

connection of current and power transducers. If the inspection cannot be completed in a timely

manner because the representative(s) is unfamiliar with the facility or project, the project site

will, at CenterPoint’s discretion, fail inspection.

3.2.11 Installation Report

The generated IR updates any information proposed in the Project Application that has now been

finalized after completion and inspection of the project. Upon IR approval, the Project Sponsor

will receive notice from CenterPoint Energy that the Installation Payment will be processed. If

the project requires M&V, this payment is 40% of the incentive approved in the IR. For deemed

savings projects, 100% of the incentive is paid for verified savings, up to the PA Approved

amount. At CNP’s discretion, incentive estimates in the Installation Report may exceed the

amount reserved during the Project Application phase only when there is remaining program

budget and no projects have been placed on a waitlist for program participation. The IR typically

includes the following information:

A customer certification form indicating that the project was installed. This form is part of

the inspection package and should be signed on site at final inspection.

Updated equipment survey forms must be submitted to reflect the removed and/or actual

installed equipment inventories, including equipment counts, equipment efficiencies, and

equipment nameplate data if it differs from the information submitted with the Project

Application. If there were no changes, the Project Sponsor may refer section 3.2.4 for forms

submitted with the Project Application.

Updates to building occupancy and equipment operating schedules to reflect changes if they

differ from the information provided with the Project Application. Please note that at least

75% occupancy ratio of the building is required.

Updated engineering calculations estimating energy and demand savings based on the

efficiency of the actual installed equipment compared to that of new, minimum-standard

efficiency equipment if it differs from the information provided with the Project Application.

A final project-specific M&V plan describing how the Project Sponsor will measure and

verify energy and demand savings, the methods for calculating actual savings, and a schedule

for conducting and reporting on M&V activities.

3.2.12 Measurement and Verification

M&V procedures will vary in detail and rigor depending on the measures installed. For each

installed measure, the chosen procedures will depend upon the predictability of equipment

CenterPoint Energy SECTION II - 30 -

operation, the availability of evaluation data from previous programs, and the benefits of the

chosen M&V approach relative to its cost. Demand savings will be calculated as the maximum,

one-hour average demand reduction that occurs when the newly installed system is operating at

peak conditions during the summer or winter period. The summer period is defined as weekdays,

between the hours of 1 P.M. and 7 P.M. from June 1 until September 30, excluding holidays. The

winter period is defined as weekdays, between the hours of 6 A.M. to 10 A.M. and 6 P.M. to 10

P.M. from December 1 to February 28, excluding holidays. Energy savings are defined as energy

savings over the course of one 12-month period. Energy and demand savings must be either

calculated using pre-approved deemed (stipulated) savings, simplified M&V procedures, or a

detailed measurement and verification plan.

Project-specific M&V procedures may be classified according to three distinct approaches that

represent increasing levels of detail and rigor.

Deemed savings: Savings values are stipulated based on engineering calculations using

typical equipment characteristics and operating schedules developed for particular

applications, without on-site testing or metering. This approach is designed for use with

lighting efficiency and controls projects, window film applications, cool roof installations,

and most cooling equipment projects.

Simplified M&V: Savings values are based on engineering calculations using typical

equipment characteristics and operating schedules developed for particular applications, with

some short-term testing or simple long-term metering. For example, energy and demand

savings from high-efficiency constant load motor installations can be determined using the

simplified approach by comparing rated efficiencies of high-efficiency equipment to standard

equipment, and using kW spot-metering and simple long-term kWh metering.

Full M&V: Savings are estimated using a more detailed method than in the deemed savings

or simplified M&V approaches through the application of metering, billing analysis, or

computer simulation. These methods will need to be developed in accordance with the 2001

International Performance Measurement and Verification Protocol (IPMVP), which

represents the starting point for standard industry practice. Project Sponsors will need to

adapt the guidelines set forth in the IPMVP to their specific projects when developing the

M&V plan required for program participation.

The time required to complete M&V activities will range from less than a month up to 12

months, depending on the approach chosen. M&V plans are not required for projects that use

deemed savings for estimating all peak demand and energy savings. By choosing deemed

savings, Project Sponsors agree to follow the procedures set-forth in this Program Manual to

determine project savings. For all other projects, a detailed savings estimate and a viable M&V

plan must be submitted for an incentive to be paid. Project Sponsors are responsible for

conducting all M&V activities for the project; however, CenterPoint Energy will work with the

Project Sponsor to facilitate M&V planning as necessary.

Please refer to Section III of the Program Manual for Measurement and Verification Guidelines

for Retrofit Projects. SECTION IV of the Program Manual contains Measurement and

Verification Guidelines for New Construction Projects. The program Web site also offers

information about the M&V procedures used to determine energy and peak demand savings for

this program.

3.2.13 Savings Report

After all M&V activities are complete, the Project Sponsor will submit a Savings Report (SR)

documenting the project’s measured demand and energy savings using eTrack. For projects

using only deemed savings, the Project Sponsor may submit the Savings Report at the same time

as the Installation Report. Upon approval of the Savings Report, the Project Sponsor will be

notified by CenterPoint Energy that the final payment will be processed. After the Savings

Report is approved, the application deposit shall be refunded. The amount of the refund is based

on the percentage of the estimated incentive payment, specified in the Project Authorization,

actually received by the Project Sponsor. Reference Table 8 in section 3.2.5 to determine the

amount of the refund.

This section includes detailed information about the measurement and verification (M&V)

requirements of the 2018 CenterPoint Energy C&I Standard Offer Program, as well as guidance

for Project Sponsors on how to prepare and execute an M&V plan. These requirements and

guidelines are specific to retrofit projects.

4 Introduction to Measurement and Verification for

Retrofit Projects

Overview In the 2018 C&I Standard Offer Program, the demand and energy savings resulting from a

project are determined through measurement and verification (M&V) activities. The M&V

methods appropriate for a given measure will depend on the equipment type, operational

predictability, and complexity involved in the retrofit. The M&V guidelines provided in the

following sections vary in detail and rigor, but fall into three general categories:

Deemed approach

Simplified Measurement approach

Full Measurement approach

The measurement methods presented in this section define how the project sponsors will

calculate system impacts from energy efficiency projects. Project sponsors will document pre

and post measurement activities, as defined in this manual, to illustrate savings impacts. The

Measurement guidelines define measurement procedures covering several of the anticipated

energy-efficiency measures (EEMs) that will be installed as part of the Energy Efficiency

Programs. The simplified and full measurement approaches must adhere to the standards of the

2007 International Performance Measurement and Inspection Protocol (IPMVP). Table 9 lists

the available measurement methods for the measures.

Program Manual v 18.1 Introduction to Measurement and Verification for Retrofit Projects

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 33 -

Measurement Approaches CenterPoint Energy has outlined three distinct M&V approaches, representing increasing levels

of detail and rigor - deemed approach, simplified measurement, and full measurement. One of

these three approaches must be taken for all C&I Standard Offer Program projects. The most

appropriate method will depend upon the availability of evaluation data from previous programs

for particular measures, the predictability of equipment operation, and the benefits of the method

relative to the costs associated with the particular M&V method chosen.

4.2.1 Deemed Approach

Deemed approach refer to a savings estimation approach that does not require short-term testing

or long-term metering. Instead, demand and energy savings are stipulated based on evaluation

data from past DSM programs or other publicly available industry data. The data are used to

make assumptions about typical operating characteristics, manufacturer’s nameplate efficiency

data, and types of equipment likely to be installed. The deemed savings M&V approach is

appropriate for energy efficiency measures for which savings are relatively certain, such as

lighting efficiency.

4.2.2 Simplified Measurement

A simplified measurement approach may involve short-term testing, but relies primarily on

manufacturer’s efficiency data and pre-set savings calculation formulas. Simplified methods can

reduce the need for extensive field monitoring or performance testing. For example, pre-retrofit

chiller demand and energy may be extrapolated for one-to-one chiller replacements by measuring

energy, flow, chill water supply and return temperatures of the new chiller. Manufacturer curves

for kW and tonnage of the old chiller are then compared to the metered data (tonnage) to

extrapolate the consumption of the old chiller. CenterPoint Energy, or its designee, may collect

the monitoring data onsite during the post-installation inspection. In cases where this is

necessary, the Sponsor is required to have any logging equipment operational until the inspection

takes place. It is the responsibility of the Sponsor to have the required equipment and personnel

to gather the data from any logging equipment.

4.2.3 Full M&V

The full measurement approach estimates demand and energy savings using a higher level of

rigor than the deemed or metered measurement approaches through the application of computer

simulation. Any full measurement methods other than computer simulation should be developed

in accordance with the 2007 International Performance Measurement and Inspection Protocol

(IPMVP) and be approved by CenterPoint Energy. In general, projects involving full

measurement must submit a project-specific measurement plan. At a minimum, the plan should

address the following (from the 2007 IPMVP):

1. Describe the project site and the project; include information on how the project saves energy

and which key variables affect the realization of savings.

2. Describe the Measurement method to be used.

3. Indicate who will conduct the Measurement activities and prepare the Measurement analyses

and documentation.

Program Manual v 18.1 Introduction to Measurement and Verification for Retrofit Projects

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 34 -

4. Define the details of how calculations will be made. For instance: “List analysis tools, such

as DOE-2 computer simulations, and/or show the equations to be used.” A complete “path”

should be defined indicating how collected survey and metering/monitoring data will be used

to calculate savings. All equations should be shown.

5. Specify what metering equipment will be used, who will provide the equipment, its accuracy

and calibration procedures. Include a metering schedule describing metering duration and

when it will occur, and how data from the metering will be validated and reported. Include

data formats. Electronic, formatted data read directly from a meter or data logger are

recommended for any short-or long-term metering.

6. Define what key assumptions will be made about significant variables or unknowns. For

instance: “actual weather data will be used, rather than typical-year data,” or “fan power will

be metered for one full year for two of the six supply air systems.” Describe any stipulations

that will be made and the source of data for the stipulations.

7. Define how any baseline adjustments will be made.

8. Describe any sampling method that will be used, what are included, sample sizes,

documentation on how sample sizes were selected, and information on how random sample

points will be selected.

9. Indicate how quality assurance will be maintained and replication confirmed.

CenterPoint Energy SECTION III - 35 -

5 Measurement Guidelines for Lighting Efficiency and

Controls

Overview The lighting projects covered by this M&V procedure are lighting efficiency measures that may

include the replacement of existing lamps and ballasts with new energy efficient lamps and

ballasts. For these types of projects, demand savings are based on coincident-load factors and

changes in lighting load as determined using standard lighting fixture wattage values listed in the

CenterPoint Energy Table of Standard Fixture Wattages (see Appendix H Table H.2). To

determine energy savings, the Sponsor should establish operating hours using one of two

methods:

Deemed Hours – Operating hours have been established for certain building types (See

Table 11).

Metered Hours – Energy savings are determined by metering pre- or post-installation

operating hours using defined sampling techniques.

For lighting efficiency measures installed in electrically cooled spaces, demand and energy

savings are also given for lighting-HVAC system interaction. These savings are equal to various

percentages of the lighting demand savings and energy savings depending on the building types

and temperatures. Evaporative or alternate fuel system credits for electricity savings must be

based on Full M&V results.

In addition to determining operating hours, the Project Sponsor is required to conduct pre- and

post-installation equipment surveys. The Project Sponsor should fill out and submit survey

results in the Retrofit Lighting Survey Form using fixture codes provided in the Table of

Standard Fixture Wattages (see Appendix H Table H.2). CenterPoint Energy or its designee will

conduct pre- and post-installation inspections to verify the reported baseline and retrofit

conditions, respectively.

Pre-Installation M&V Activities

5.2.1 Pre-Installation Equipment Survey

Prior to installing the lighting retrofit, the Project Sponsor conducts a pre-installation equipment

survey, to be submitted as part of the Project Application. The purpose of the pre-installation

equipment survey is to inventory all existing lighting equipment, and to propose the replacement

equipment to be installed. This survey should provide the following information about all

fixtures: room location, fixture, lamp, and ballast types, lighting controls, area designations,

counts of operating and non-operating fixtures, and type of control device. Surveys should

include all baseline lighting fixtures and controls, regardless of whether they will be retrofitted.

Fixture wattages are based on the fixture codes listed in the Table of Standard Fixture Wattages

(see Appendix H Table H.2). This information should be tabulated electronically in the Retrofit

Lighting Survey Form.

Page 36: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Lighting Efficiency and Controls

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 36 -

5.2.2 Non-operating fixtures

The number of non-operating baseline fixtures will be limited to 10% of the total fixture count

per facility. If, for example, more than 10% of the total number of fixtures is inoperative, the

number of inoperative fixtures beyond 10% will be assumed to have a baseline fixture wattage of

zero. Thus, the total baseline demand for the project will be adjusted accordingly.

5.2.3 Pre-Installation Inspection

CenterPoint Energy or its designee may conduct a pre-installation inspection to verify that the

Sponsor has properly documented the baseline. The criterion for baseline acceptance is that the

installed demand of the inspected sample must be within 10% of the demand reported on the

Retrofit Lighting Survey Form to avoid fees. Any errors will be corrected in a revised Retrofit

Lighting Survey Form. If the project fails the initial inspection, the Project Sponsor will bear the

cost of subsequent inspections. The operating hours of the baseline lighting system are assumed

to be the same as those of the post-retrofit lighting system and are not measured as part of the

pre-installation M&V activities.

5.2.4 Installation Inspection

CenterPoint Energy or its designee may conduct an inspection after the Sponsor sends the

installation notice. The criterion for acceptance remains the same as the pre-installation

inspection but will also include surveying the equipment to be installed. If the project fails

inspection due to incorrect survey forms or not having materials or necessary equipment on site

for the install, the Project Sponsor will bear the cost of subsequent inspections. Failure to have

the equipment to be installed on-site will result in the failure of the inspection and will require

an additional inspection to take place, resulting in an inspection fee, See Table 7.

5.2.5 Installation Guidelines

Lighting measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

Post-installation M&V Activities

5.3.1 Post-Installation Equipment Survey

The Sponsor is required to conduct a post-installation lighting equipment survey as part of the

Installation Report. The purpose of the post-installation equipment survey is to inventory the

actual, as-built post-retrofit equipment. Fixture wattages shall be based on the Table of Standard

Fixture Wattages. In the IR, the proposed equipment information listed in the approved Project

Application shall be updated to reflect the actual post-retrofit conditions and equipment found

during the survey after installation. Any equipment listed in the approved Project Application

that was not in fact replaced should remain in the lighting equipment inventory – in this case,

simply copy the pre-retrofit information to the post-retrofit columns.

Program Manual v 18.1 Measurement Guidelines for Lighting Efficiency and Controls

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 37 -

5.3.2 Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

retrofit was installed as reported. In most cases, CenterPoint Energy or its designee will inspect

statistically significant samples taken from the entire lighting population. The criterion for

acceptance is that installed demand of the inspected sample must be within 10% of the demand

reported on the post-installation Retrofit Lighting Survey Form to avoid fees. Any errors will be

corrected in a revised Retrofit Lighting Survey Form.

Operating Hours

5.4.1 Deemed Hours

The Deemed Hours Method uses predetermined annual operating hours and co-incidence factors,

the interactive demand and energy savings factors as listed in Table 12. If this table does not

accurately characterize the building type, then the Project Sponsor should refer to the Stipulated

Hours Method or the Metered Hours Method section for the appropriate Measurement techniques

to calculate operating hours. The Public Utility Commission of Texas (PUC) approved the

revision of existing measurement & verification guidelines for lighting measures for energy

efficiency programs in the latest version of the Texas Technical Reference Manual, and the

updated building lighting operating hours and associated coincidence factors are listed in Table

11.

5.4.2 Metered Hours

The Metered Hours Method involves monitoring a statistically significant sample of fixtures to

determine operating hours. This involves developing a sampling plan to monitor the average

operating hours for each lighting usage group. The Project Sponsor should conduct all meter

installation, retrieval and data analysis. When performing the pre-installation activities associated

with this Measurement approach, Project Sponsors should organize the equipment into usage

groups—collections of equipment with similar operating schedules and functional uses. For

instance, although a site's open office lighting may have the same annual hours of operation as

the private office lighting, the two have different functional uses. In this case, a change in the

operating hours of the private office lights due to the installation of an occupancy sensor would

not be relevant to the operating hours of the open office lights. Therefore, private offices and

open office areas should be assigned to separate usage groups.

Table 13 illustrates the recommended minimum number of usage groups, specific to each project

site.

The Project Sponsor will conduct short-term metering of the operating hours for a random

sample of fixtures in each usage group. For facilities with little variation in weekly operating

schedules (such as offices), monitoring shall be conducted for each selected circuit for a

recommended minimum of two to four weeks. Monitoring should not occur during significant

holidays or vacations. If a holiday or vacation falls within the monitoring period, the duration

should be extended for as many days as that holiday or vacation. For facilities where operating

hours vary seasonally, monitoring should be conducted for a minimum period during each

season.

The required sample sizes for each usage group are listed in Table 14. Note: because light

loggers sometimes fail, over sampling is recommended. Light loggers should be calibrated prior

to installation to verify that the light loggers are functioning properly. If there are multiple

the populations indicated

5.4.3 Calculation of Average Operating Hours

For each usage group, the Project Sponsor should extrapolate results from the monitored sample

to the population to calculate the average annual lighting operating hours. Simple, unweighted

averages of operating hours should be calculated for each usage group as listed in the following

equations. The Project Sponsor should use these average operating hours to calculate the energy

savings for each respective usage group.

5.4.4 Calculation of Average Coincidence Factor

The equation listed below illustrates the calculation of average on-peak demand coincidence

factor (CF) for a usage group. Note that demand savings are only allowed for lighting fixtures

that will be in operation on weekdays between the hours of 1 PM and 7 PM during the months of

June through September.

5.5.1 Deemed Control Savings

This method requires the use of the deemed hours from Table 11 and a Power Adjustment Factor

(PAF) and Energy Adjustment Factor (EAF) from Table 15. If values from these tables do not

accurately characterize the building type and operation, then the Project Sponsor must refer to

If the project is ineligible for deemed savings and/or the Project Sponsor prefers to monitor

Operating Hours to claim achievable savings, the Metered Hours Method must be followed to

determine operating hours (Refer to Pages 7-9 of the 2007 International Performance

Measurement and Inspection Protocol). If the project involves the addition of lighting controls

to a building that does not fall under the deemed category and the stipulated method is

inadequate to determine pre-operating hours, then pre- and post-installation metering may be

required to determine pre- and post-operating hours.

6 Measurement Guidelines for Replacement of Cooling

Equipment

Overview Cooling equipment retrofits involve the replacement of the existing equipment with high-

efficiency equipment. This chapter presents both a deemed savings approach and a full approach

to the measurement and inspection of savings from the retrofit of cooling equipment. In general,

the measurement methods described in this chapter can be used for projects involving the one-

for-one change-out of cooling equipment. Potential qualifying equipment includes:

Unitary air conditioners (DX, air-cooled, evaporative, or water-cooled)

Heat pumps (air-cooled, evaporative, or water-cooled)

Chillers (air-cooled centrifugal, water-cooled centrifugal, air-cooled screw, etc.)

Compressors (centrifugal, screw, reciprocating)

Fuel switching from electric to gas engine-driven cooling equipment

Page 44: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Replacement of Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 44 -

The retrofits must have the following characteristics:

The newly installed electric cooling equipment capacity must be within 80% to 120% of the

replaced electric cooling equipment capacity.

The newly installed electric cooling equipment must not be redundant, backup or off –peak

use only equipment.

No additional measures are being installed that directly affect the operation of the cooling

equipment (i.e., control sequences, cooling towers, and condensers).

If the proposed retrofit does not meet these requirements, refer to the Full Measurement

guidelines for appropriate Measurement techniques. The baseline efficiency used in the savings

calculation for replace-on-burnout of Unitary ACs, Heat Pumps, and Room ACs is either

ASHRAE 2007/2010 or the Federal Manufacturer Standard. Baseline efficiency for Chillers and

Packaged Terminal Air Conditioners and Heat Pumps is either IECC 2009 or ASHRAE 90.1-

1999 (for water-cooled chillers). Efficiency values from this standard can be found in the

Standard Cooling Equipment Tables under the heading “Baseline Performance Standard”,

Appendix I of the Appendices to M&V Guidelines found at the end of this document. Early

retirement is an available option for projects involving chilled water systems and package or split

unitary air-conditioners and heat pumps that involve replacement of a working system. Baseline

efficiency will be estimated according to the capacity, type (e.g. for unitary systems, whether

package or split, heat pump or air conditioner), and the year of manufacture of the replaced

system and can be found in the Standard Cooling Equipment Tables in Appendix I.

Deemed Savings for Cooling Equipment The deemed savings approach to Measurement for cooling equipment is applicable to both one-

for-one equipment replacement as well as equipment replacement involving a change in

equipment type, e.g., changing from air-cooled DX units to a water-cooled chiller. An air-cooled

to water-cooled equipment measure requires an additional step to account for the auxiliary

devices to support a water-cooled chiller. The deemed savings methodology is incorporated in

an Excel spreadsheet, available to Project Sponsor, which calculates savings values based on

user inputs. For replacements involving, changes in equipment type, the calculations must be

done manually.

The efficiency of the installed equipment must exceed the efficiency as listed under the current

City of Houston Commercial Energy Code or Federal Standard whichever is more stringent

for the appropriate equipment type and capacity.

Projects that are eligible to use the deemed savings approach must meet the following

requirements:

The existing and proposed cooling equipment are electric.

The Cooling Equipment is not used for process loads.

Coefficients are listed in Appendix I Table I.1- Table I.8 for the type of building in which the

retrofit occurs and the type of equipment involved.

The building falls into one of the categories described in Table 16

6.2.1 Pre –Installation Measurement Activities

Proof of Equipment Purchase

Sponsors must submit, within 30 days of the application approval, documentation showing the

new equipment is on order and should be delivered within the timeframe of the SOP.

Pre-Installation Equipment Survey

The goals of the pre-installation site survey are to identify the cooling equipment, establish the

retrofit type (whether it will be replace-on-burnout or early retirement) and establish the baseline

efficiency. The information collected should include: equipment type, year, make/model, rated

capacity, rated efficiency, and an assessment of its working condition. The baseline efficiency is

established according to the retrofit type: for replace-on-burnout projects, baseline efficiencies

are determined by recent Federal or manufacturing standards, and are published in Table I.1

through Table I.8. The baseline efficiency listed in the Standard Cooling Equipment Table I.12

through Table I.27 in Appendix I.

The baseline efficiency is equal to the more efficient of the two values. The goals of the pre-

installation survey are to identify the cooling equipment and establish the baseline efficiency.

The information collected should include: equipment type, year, make/model, rated capacity,

rated efficiency. The Project Sponsor should record information about the cooling equipment in

the deemed savings spreadsheet.

Pre-Installation Inspection

CenterPoint Energy or its designee will conduct a pre-installation inspection to verify that the

Project Sponsor has properly documented the baseline. Demolition or removal of existing

equipment and/or installation of new equipment cannot commence until the pre-installation

inspection is completed and CenterPoint Energy has executed the Project Authorization.

Installation Guidelines

HVAC measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

6.2.2 Post-Installation Measurement Activities

Post-Installation Equipment Survey

Once the retrofit is complete, the Project Sponsor conducts and submits a post-installation

equipment survey. The survey should include: installed equipment type, year, make/model, rated

capacity, and rated efficiency and pertinent information about the cooling equipment recorded in

the deemed savings spreadsheet. The Project Sponsor must submit manufacturer’s

documentation of the rated efficiency of all newly installed cooling equipment, based upon ARI

test conditions. This documentation will be in the form of manufacturer cut sheets or factory

performance test results that document the part load performance of the equipment.

Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

equipment was installed as reported and is documented accurately.

Simplified Measurement for Cooling Equipment

The simple M&V procedure for electric-to-electric cooling equipment replacement involves

collecting one year of post-consumption kWh data. To determine demand savings, the

maximum equipment demand that occurs during the utility peak hours must be measured. This

can be accomplished with continuous demand metering or spot metering during peak conditions.

6.3.1 Pre –Installation Measurement Activities

Proof of Equipment Purchase

Sponsors must submit, within 30 days of the application approval, documentation showing the

new equipment is on order and should be delivered within the timeframe of the SOP.

CenterPoint Energy SECTION III - 49 -

Pre-Installation Equipment Survey

The goals of the pre-installation site survey are to identify the existing equipment, evaluate its

schedule of use, and establish the baseline efficiency or coefficient of performance (COP). The

Project Sponsor will conduct a survey of all the existing cooling equipment for buildings with a

central plant, regardless of whether they will be retrofitted. The information collected should

include: equipment type, year, make/model, rated capacity, rated efficiency, operating schedule,

and operating sequence. Record the equipment information in the Cooling Equipment Inventory

Form.

The baseline efficiency is determined by comparing the rated efficiency of the existing unit to

the minimum efficiency listed in the Standard Cooling Equipment Table I.12 through Table I.27,

which are based on ASHRAE 90.1-1989, provided in Appendix I. The baseline efficiency is

equal to the more efficient of the two values.

Pre-Installation Inspection

CenterPoint Energy or its designee will conduct a pre-installation inspection to verify that the

Project Sponsor has properly documented the baseline. Demolition or removal of existing

equipment and/or installation of new equipment cannot commence until the pre-installation

inspection is completed and CenterPoint Energy has executed the Project Authorization.

Pre-Installation Monitoring

The simple M&V procedure for electric-to-electric cooling equipment replacements does not

require pre-installation monitoring of existing equipment. The existing equipment efficiency is

determined from the Standard Cooling Equipment Table I.1 through Table I.8, Appendix I. The

existing equipment load and operating schedule are assumed to be the same as those of the post-

retrofit equipment.

The simple M&V procedure for electric-to-gas cooling equipment replacement does require pre-

installation monitoring of the existing equipment. The maximum demand (measured for a one-

hour period) that coincides with the utility peak demand period must be determined, through spot

measurements or continuous metering. The annual energy usage of the existing equipment must

also be established through measurements, or predicted by a method approved by CenterPoint

Energy.

Installation Guidelines

HVAC measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

6.3.2 Post-Installation Measurement Activities

Post-Installation Equipment Survey

Once the retrofit is complete, the Project Sponsor conducts and submits a post-installation

equipment survey. The survey should include: installed equipment type, year, make/model, rated

capacity, and rated efficiency and pertinent information about the cooling equipment recorded in

the deemed savings spreadsheet. The Project Sponsor must submit manufacturer’s

documentation of the rated efficiency of all newly installed cooling equipment, based upon ARI

test conditions. This documentation will be in the form of manufacturer cut sheets or factory

performance test results that document the part load performance of the equipment.

Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

equipment was installed as reported and is documented accurately.

Post-Installation Monitoring

Two basic steps comprise the necessary post-retrofit M&V monitoring activities for electric-to-

electric cooling equipment replacements:

1. Measure the maximum demand (measured for a one-hour period) that occurs between the

hours of 1 PM and 7 PM on weekdays during the months of June through September. This

can be accomplished with continuous demand metering (at 15-minute intervals) or a spot

measurement during peak conditions.

2. Collect twelve months of post-installation consumption (kWh) data.

For electric-to-gas fuel switching cooling equipment replacements, twelve months of post-

installation gas usage is required in the simple M&V procedure. If the new gas-engine chiller

included installation of new electric auxiliary equipment, such as a condenser water pump and

cooling tower fan, the peak demand and annual energy consumption for this additional

equipment must be metered and subtracted from the chiller savings.

6.3.3 Calculation Methodology

Appended below are equations relating to peak demand and energy savings calculations. These

calculations are embedded in the pertinent CenterPoint Energy Cooling Equipment Form.

Electric to Electric Equipment Replacements

Demand savings are allowed only for new equipment that will be in operation during the peak

periods. Peak demand and energy savings are calculated according to Equations below.

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 × (𝐶𝑂𝑃𝑝𝑜𝑠𝑡

𝐶𝑂𝑃𝑏𝑎𝑠𝑒𝑙𝑛𝑒− 1)

𝐶𝑂𝑃𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒− 1) × (

𝐶𝐷𝐷(65)𝑇𝑀𝑌

𝐶𝐷𝐷(65)𝑚𝑒𝑡𝑒𝑟𝑒𝑑)

Where:

𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = maximum metered 15-minunte cooling equipment demand during the utility peak-

demand period, kW

𝑘𝑊ℎ𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = summed metered cooling equipment energy use for one year, kWh

𝐶𝑂𝑃𝑝𝑜𝑠𝑡=installed cooling equipment coefficient-of-performance at ARI design conditions

𝐶𝑂𝑃𝑏𝑎𝑠𝑙𝑖𝑛𝑒 = baseline cooling equipment coefficient-of-performance from Table I.1 through

Table I.8 in Appendix I

𝐶𝐷𝐷(65)𝑇𝑀𝑌=cooling degree days (base 65 F) for a typical meteorological year for the National

Climatic Data Center station nearest the site. The value is available in Appendix

Table I.9.

Full Measurement for Cooling Equipment The Full Measurement procedure for electric-to-electric cooling equipment replacement or

savings realized at the cooling equipment, due to control strategies, VAV modifications, building

shell improvements, etc, requires a building simulation. Any full measurement methods other

than computer simulation should be developed in accordance with the 2007 International

Performance Measurement and Inspection Protocol (IPMVP) and be approved by CenterPoint

Energy. Computer Simulation Analysis for measurement and verification of energy savings is

used when the energy impacts of the energy efficiency measures (EEMs) are too complex1 or too

costly to analyze with traditional M&V methods. Situations where computer-based building

energy simulations may be appropriate include:

The EEM is an improvement or replacement of the building energy management or control

system.

There is more than one EEM and the degree of interaction between them is unknown or too

difficult or costly to measure.

The EEM involves improvements to the building shell or other measures that primarily affect

the building load (e.g., thermal insulation, low-emissivity windows).

The M&V method described here is based, in part, on Option D of the 2007 International

Performance Measurement and Verification Protocol (IPMVP). Valuable insights on computer

CenterPoint Energy SECTION III - 52 -

simulation analysis can be found in the IPMVP. The Project Sponsor should take the following

steps in performing Computer Simulation Analysis M&V:

1. Work with CenterPoint Energy and its designee to define a strategy for creating a calibrated

building simulation model in the project-specific M&V plan.

2. Collect the required data from utility bill records, architectural drawings, site surveys, and

direct measurements of specific equipment installed in the building.

3. Adapt the data and enter them into the program’s input files.

4. Run the simulation program for the “base” building model. The base building is the existing

building without the installed EEMs. The base building should comply with minimum state

and federal energy standards.

5. Calibrate the base model by comparing its output with measured data. The weather data for

the base model should be the actual weather occurring during the metering period. Refine the

base building model until the program’s output is within acceptable tolerances of the

measured data.

6. Run the calibrated base model using typical weather data to normalize the results.

7. Repeat the process for the post-installation model. Calibration of the retrofit model, if done,

should use data collected from site surveys (to validate that all the equipment and systems are

installed and operating properly) and possibly spot short-term or utility metering.

8. Estimate the savings. Savings are determined by subtracting the post-installation results from

the baseline results using typical conditions and weather. The savings estimates and

simulation results will be reviewed and verified by CenterPoint Energy or its designee.

These steps are described in more detail in the following sections.

6.4.1 Baseline and Post-Retrofit Data Requirements

Simulation Software

To conduct Calibrated Simulation Analysis M&V, it is recommended that the Project Sponsor

use the most current version available of the DOE-2.1E hourly building simulation program. For

projects with small projected incentive payments, the Project Sponsor may use other models if

the model can be shown to adequately model the project site and the EEMs can be calibrated to a

high level of accuracy, and the calibration can be documented.

Weather Data

Calibrating a computer simulation of a real building for a specific year requires that actual

weather data be used in the analysis. Actual weather data should be collected from a source such

as National Climatic Data Center (NCDC) weather station data. The physical location of the

weather station should be the closest available to the project site. These data should be translated

into weather data files that are compatible with DOE-2. The project-specific M&V plan should

specify which weather data sources will be used. Typical weather data used in the calculation of

energy savings should be either Typical Meteorological Year (TMY2) or TMY3 data types,

obtained from the National Renewable Energy Laboratory (NREL).

Develop a Calibrated Simulation Strategy

The following are issues that either the Project Sponsor or CenterPoint Energy will need to

address to define the simulation approach:

Page 53: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Replacement of Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 53 -

Define the existing building. In general, the existing building represents the building, as it

exists prior to installation of EEMs by the Project Sponsor.

Define the baseline building. The baseline building represents the existing building but with

baseline equipment efficiencies as specified by state or federal standards.

Define the post-installation building. The post-installation building represents the building

with the project-related EEMs installed.

Define the calibration data interval. The building models should be calibrated using

hourly, daily, or monthly data. Calibrations to hourly or daily data are preferred to monthly

data, since the former is more accurate than the latter, due to more comparison points. If

monthly project site billing data is used, then spot or short-term data collection for calibrated

key values may be used.

Specify spot and short-term measurements to be taken of building systems. These

measurements augment the whole-building data and enable the modeler to accurately

characterize building systems. Spot and short-term measurements are valuable, but may add

significant cost and time to the project.

Employ an experienced building modeling professional. Although new simulation

software packages make much of the process easier, a program’s capabilities and real data

requirements are not fully understood by inexperienced users. Employing inexperienced

users for this purpose will result in inefficient use of time in data processing, and in checking

and understanding of simulation results.

Building Data Collection

The main categories of data to be collected for the building and proposed EEMs are described

below.

Building plans. The Project Sponsor should obtain as-built building plans. If as-built plans

are not available, the Project Sponsor should work with the building owner to define

alternative sources.

Utility bills. The Project Sponsor should collect a minimum of twelve consecutive months

(preferably 24 months), with applicable dates of utility bills for the months immediately

before installation of the EEMs. The billing data should include monthly kWh consumption

and peak electric demand (kW) for the month. Fifteen minute or hourly data are also desired

for calibration. The Project Sponsor should determine if building systems are sub-metered,

and collect these data if available. If hourly data are required to calibrate the simulation, but

no data are available, metering equipment may need to be installed to acquire hourly data.

Conduct on-site surveys. CenterPoint Energy or its designee will assist the Project Sponsor

to identify the necessary data to be collected from the building. The Project Sponsor should

visit the building site to collect the data. CenterPoint Energy or its designee may accompany

the Project Sponsor during the building survey. Data that may be collected include:

HVAC systems - primary equipment (e.g. chillers and boilers): capacity, number, model

and serial numbers, age, condition, operation schedules, etc.

HVAC systems - secondary equipment (e.g., air handling units, terminal boxes):

characteristics, fan sizes and types, motor sizes and efficiencies, design flow rates and

static pressures, duct system types, economizer operation and control

HVAC system controls, including location of zones, temperature set-points, control set-

points and schedules, and any special control features

Program Manual v 18.1 Measurement Guidelines for Replacement of Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 54 -

Building envelope and thermal mass: dimensions and type of interior and exterior walls,

properties of windows, and building orientation and shading from nearby objects

Lighting systems: number and types of lamps, with nameplate data for lamps and

ballasts, lighting schedules, etc.

Plug loads: summarize major and typical plug loads for assigning values per zone

Building occupants: population counts, occupation schedules in different zones

Other major energy consuming loads: type (industrial process, air compressors, water

heaters, elevators), energy consumption, schedules of operation, etc.

Interview operators. The Project Sponsor may choose to interview the building operator.

Building operators can provide much of the above listed information, and indicate if any

deviation in the intended operation of building equipment exists.

Make spot measurements. The Project Sponsor may find it necessary to record power draw

on certain circuits (lighting, plug load, HVAC equipment, etc.) to determine actual

equipment operation power.

Conduct short-term measurements. Data-logging monitoring equipment may be set up to

record system data as they vary over time. These data reveal how variable load data changes

with building operation conditions such as weather, occupancy, daily schedules, etc. These

measurements may include lighting systems, HVAC systems and motors. The period of

measurement should be from one to several weeks.

Obtain weather data. For calibration purposes, representative site weather data should be

obtained for a nearby NCDC site.

Base Building Simulation Models

Once all necessary information is collected, the Project Sponsor should input the simulation data

into DOE-2 code to create the base building model. The modeler should refine the model to

obtain the best representation of the base building. Where possible, the modeler should use

measured data and real building information to verify or replace the program’s default values.

Minimum Energy Standards

The baseline model should comply with minimum state and federal energy standards with

respect to the following:

Baseline equipment/systems models should not include devices (e.g., lamps and ballasts) that

are not allowed to be installed under current regulations.

Baseline equipment models should meet prescriptive efficiency standards requirements for

affected equipment.

Baseline calculations do not have to comply with performance compliance methods that

require the project site to meet an energy budget.

If the existing conditions of the EEMs do not comply with minimum state and federal standards,

the modeler should calibrate the simulation model with the building as it currently exists, and

then modify the existing building model to reflect the baseline efficiencies. This modified, or

baseline building is then used as the base case for computing energy savings.

Page 55: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Replacement of Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 55 -

6.4.2 Calibration

After the base building model has been created and debugged, the modeler should make a

comparison of the energy flows and demand projected by the model to that of the measured

utility data. All utility billing data should be used in the analysis, electric as well as heating fuels,

such as natural gas. The modeler may use either monthly utility bills, or measured hourly data to

calibrate the model when available. The calibration process should be documented to show the

results from initial runs and what changes were made to bring the model into calibration.

Statistical indices are calculated during the calibration process to determine the accuracy of the

model. If the model is not sufficiently calibrated, the modeler should revise the parameters of the

model and recalculate the statistics.

Hourly Data Calibration

In hourly calibration, two statistical indices are required to declare a model “calibrated”: monthly

mean bias error (MBE) and the coefficient of variation of the root mean squared error (CV

(RMSE))2. Equations related with the calculation of MBE and CV (RMSE) is listed below. The

acceptable tolerances for these values when using hourly data calibration are shown in Table 17.

𝑀𝐵𝐸 (%) =∑ (𝑀 − 𝑆)ℎ𝑟𝑚𝑜𝑛𝑡ℎ

∑ 𝑀ℎ𝑟𝑚𝑜𝑛𝑡ℎ × 100

Where:

𝑀ℎ𝑟 = the measured kWh for any hour during the month

𝑆ℎ𝑟 = the simulated kWh for any hour during the month

𝐶𝑉𝐸 (𝑅𝑀𝑆𝐸𝑚𝑜𝑛𝑡ℎ) =√∑ (𝑀 − 𝑆)2

ℎ𝑟 × 𝑁ℎ𝑟 𝑚𝑜𝑛𝑡ℎ

∑ 𝑀ℎ𝑟𝑚𝑜𝑛𝑡ℎ × 100

Where:

𝑀ℎ𝑟 = the measured kWh for any hour during the month

𝑆ℎ𝑟 = the simulated kWh for any hour during the month

𝑁ℎ𝑟 = the number of hours in the month

Table 17. Acceptable Tolerances for Hourly Data Calibration

Value

MBEmonth 10%

CV(RMSEmonth) 30%

Monthly Data Calibration

Comparing energy use projected by simulation to monthly utility bills is straightforward. First

the model is developed and run using weather data that corresponds to the monthly utility billing

periods. Next monthly-simulated energy consumption and monthly measured data are plotted

6.4.3 Post-Installation Models

After the measures are installed, a post-installation model can be prepared. The post-installation

model should usually be the baseline model with the substitution of new energy-efficient

equipment and systems. This new model should also be calibrated and documented. The possible

calibration mechanisms are:

Using site survey data to validate that all the specified equipment and systems are installed,

have the nameplate data used in the model, and are operating properly.

Using spot and/or short-term metering data to calibrate model modules of equipment,

systems or end-uses.

Using utility (15 minute, hourly, or monthly) metering data to calibrate the model, as was

done with the pre-installation model.

The above mentioned post-installation model calibration mechanisms are not necessarily

mutually exclusive. If the first two mechanisms are used the model can be calibrated soon after

measure installation. If the last mechanism is used then the model can only be calibrated after

sufficient (e.g., 12 months) billing data are available. In some instances, the post-installation

model should be the only model calibrated. This can occur when the baseline project site cannot

be easily modeled due to significant changes during the 12 months prior to the new measures

being installed and thus the recent billing data are not representative.

6.4.4 Detailed Energy Savings Calculations

Energy savings are determined from the difference between the outputs of the baseline and post-

installation models. Savings are determined with both models using the same conditions

(weather, occupancy schedules, etc.). To calculate savings, the energy consumption projected by

the post-installation model is subtracted from energy consumption projected by the baseline

model. Energy savings are calculated by the following equation.

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 58 -

7 Measurement Guidelines for Constant Load Motor

Measures

Overview This measurement and verification (M&V) method is appropriate for projects involving existing

motors serving a constant load being replaced with higher efficiency motors of equal or lesser

capacity (horsepower). The rated efficiency of the new motor must exceed the minimum

efficiency standard defined in the Table of Standard Motor Efficiencies in Appendix J Table J.2

to be eligible for the program. Potential retrofit equipment includes:

Constant load chilled water, hot water, or condenser water pumps

Constant speed exhaust, return, and supply fans without dampers or pressure controls

Single-speed cooling tower fans

Constant load industrial processes

Similar capacity, constant speed, energy efficiency motors

Smaller, constant speed, energy efficiency motors when the existing motor is oversized

These M&V procedures are not appropriate for motor change outs that are accompanied by:

Changes in operating schedule

Changes in operating hours

Changes in flow rate

Changes in motor controls (except VSDs)

If the proposed retrofit does not meet the constant load requirements, or involves scheduling or

operational changes, refer to the Full M&V Guidelines for Generic Variable Loads in Chapter 12

for appropriate M&V techniques.

Incentives are available for the installation of premium efficiency motors. Deemed savings

are calculated by completing the Premium Efficiency Motor Form.

In the C&I Standard Offer Program, the calculation of demand and energy savings for motor

replacements is based on the baseline and post-installation kW, the difference in efficiency of the

baseline and new motors, and the motor operating hours. The operating hours are assumed the

same for existing and new motors. The baseline motor efficiency is based on the minimum

efficiency rating defined by the Table for Standard Motor Efficiencies in Appendix J. The Table

of Standard Motor Efficiencies is categorized by motor size and rotation speed. The baselines for

motors whose efficiencies are not listed in the table will be determined on a case-by-case basis

by CenterPoint Energy. The project sponsor must provide demonstrable proof that energy

efficiency was a key criterion in the motor-selection process to qualify for incentives. No

incentive payments are made for replacement motors with efficiencies equal to or less than the

baseline efficiency. In addition to having a higher efficiency than baseline motors, all new

motors should meet minimum equipment standards as defined by state and federal law.

Program Manual v 18.1 Measurement Guidelines for Constant Load Motor Measures

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 59 -

The recommended M&V approach for motors includes some or all of the following data

collection activities:

Compiling inventories for existing and new motors

Short-term metering of existing motors to verify constant loading (if warranted)

Spot metering of all existing and new motors

Short-term metering of a sample of the new motors to determine operating hours

Pre-Installation Measurement Activities The M&V steps that characterize the existing motors are:

1. Pre-installation equipment survey (to be conducted by the Sponsor)

2. Spot measurement of demand (kW), and short-term metering of existing motors, where

needed (to be conducted by the Sponsor)

3. Pre-installation inspection (to be conducted by CenterPoint Energy or its designee)

7.2.1 Pre-Installation Equipment Survey

The Sponsor should conduct a pre-installation survey to inventory the equipment to be replaced

and record data about each motor in the Motor and VFD Inventory Form. Motor location and

corresponding facility mechanical plans should be included with the survey submittal as part of

the Project Application. At a minimum, the surveys should include the following for each

existing motor:

Motor name

Load served

Motor location

Operating schedule

Equipment manufacturer

Nameplate data including model, horsepower, and speed

The baseline motor efficiency should be determined from the Table of Standard Motor

Efficiencies based on the existing motor data provided in the Project Application. The baselines

for motors whose efficiencies are not listed in the table will be determined on a case-by-case

basis by CenterPoint Energy. The project sponsor must provide demonstrable proof that energy

efficiency was a key criterion in the motor-selection process.

Any M&V activities that need to be conducted prior to the demolition of existing equipment (i.e.,

short-term measurements) should take place at this time. Demolition of existing equipment

and/or installation of new equipment cannot begin until baseline M&V activities are

completed, the pre-installation inspection is completed, and CenterPoint Energy has

approved the Project Application and issued a Project Authorization.

7.2.2 Spot and Short-term Measurement of Existing Motors

To establish the baseline kW, the Sponsor must conduct spot measurements of the power draw of

the existing motors. If the constant load criterion cannot be verified by visual inspection, then

short-term metering of the power draw or current (amperes) of the existing motors may also be

required.

Page 60: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Constant Load Motor Measures

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 60 -

The verification of constant motor loading by short-term metering is warranted in situations

where the effect of piping, valves, controls, or processes on motor load is uncertain. A motor

load is constant if 90% of all non-zero observations are within 10% of the running average

kW. If short-term metering demonstrates that the proposed retrofit does not meet the constant

load definition, then the Sponsor should refer to the Full M&V Guidelines for Generic Variable

Loads in Chapter 12 for appropriate M&V techniques.

To compensate for the variations in spot measurements that occur even in constant-load motors,

the Sponsor may need to develop normalization factors for groups of like motors serving similar

loads. A normalization factor is the ratio of a motor’s average current (from short-term metering)

to its spot measured current. CenterPoint Energy may require the use of a normalization factor

for projects with a group or groups of identical motors.

The minimum efficiency standard for the existing motor type is listed in the Table of Standard

Motor Efficiencies. If the efficiency of the existing motor is greater than or equal to the

minimum efficiency standard, then the baseline demand is equal to the spot measured value. If

not, then the baseline demand is calculated according to Equation below.

𝑘𝑊𝑝𝑟𝑒 =

𝜂𝑝𝑟𝑒

𝜂𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒× 𝑘𝑊𝑝𝑟𝑒,𝑚𝑒𝑡𝑒𝑟𝑒𝑑

Where:

𝜂𝑝𝑟𝑒=existing motor efficiency

𝜂𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 = standard minimum motor efficiency

𝑘𝑊𝑝𝑟𝑒,𝑚𝑒𝑡𝑒𝑟𝑒𝑑= spot measured existing motor demand, kW

7.2.3 Pre-Installation Inspection

CenterPoint Energy will conduct a pre-installation inspection to verify that the existing condition

is as reported in the pre-installation equipment survey in the Project Application. CenterPoint

Energy will require the Sponsor to make any necessary corrections to the Project Application

based upon the results of the inspection.

Demolition of existing equipment and/or installation of new equipment cannot begin until the

pre-installation inspection is completed and CenterPoint Energy has approved the Project

Application and issued a Project Authorization.

7.2.4 Installation Guidelines

Motor measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

Post-Installation Measurement Activities The M&V steps that characterize the new motors are:

1. Post-installation equipment survey (to be conducted by the Sponsor)

Page 61: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Constant Load Motor Measures

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 61 -

2. Spot measurements of the power draw (one-hour average values) of all the new motors (to be

conducted by the Sponsor)

3. Post-installation inspection (to be conducted by CenterPoint Energy or its designee)

4. Short-term metering of operating hours for a sample of existing motors (to be conducted by

the Sponsor)

7.3.1 Post-Installation Equipment Survey

The Sponsor shall conduct a post-installation equipment survey and record data about each

motor in the Motor and VFD Inventory Form. The survey shall reflect the actual, as-built

conditions of the project. The post-installation survey will be included in the Installation Report.

7.3.2 Spot Measurements of Motor Demand

The Sponsor must conduct spot measurements of the power draw (one-hour average values) of

each new, high-efficiency motor to establish the post-installation demand. The Sponsor will

report the measured kW as part of the Installation Report.

7.3.3 Post-Installation Inspection

Once CenterPoint Energy receives the Installation Report for the motor project, CenterPoint

Energy or its designee will conduct a post-installation inspection to verify that the equipment

specifications are correctly reported in the Installation Report. CenterPoint Energy will require

the Sponsor to make any necessary corrections to the Installation Report based upon the results

of the inspection.

7.3.4 Short-Term Metering of Motor Operating Hours

Baseline motor operating hours are assumed to be the same as post-installation operating hours,

and should be determined after new motor installation. Short-term metering is used to determine

both pre- and post-installation operating hours.

After CenterPoint Energy approves the Installation Report, the Sponsor should begin short-term

metering of motor operating hours. The metering must be conducted for a minimum period of

one week, or a sufficient amount of time to capture the full range of operation. The motor annual

operating hours are calculated from the metering data according to Equation below.

𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 =𝐻𝑜𝑢𝑟𝑠𝑜𝑛

𝐻𝑜𝑢𝑟𝑠𝑚𝑒𝑡𝑒𝑟𝑒𝑑× 8760

Where:

𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 = Average annual operating hours

𝐻𝑜𝑢𝑟𝑠𝑜𝑛 = Operating hours observed during the metering period

𝐻𝑜𝑢𝑟𝑠𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = Total number of hours in the metering period

For projects in which a large number of equal-sized motors with the same application and

operating schedule will be replaced, metering may be conducted on a sample of the motors and

CenterPoint Energy SECTION III - 62 -

the results extrapolated to the applicable population. If this approach is adopted, CenterPoint

Energy will assist the Sponsor in selecting the motors to be metered.

The Sponsor should include electronic copies of the unprocessed data files as part of the Savings

Report.

Calculation of Peak Demand and Energy Savings Demand savings are calculated for equipment that operates during the summer or winter peak

period, which is defined as weekdays between the hours of 1 p.m. and 7 p.m. from June 1

through September 30 during summer and weekdays between the hours of 6 a.m. to 10 a.m. and

6 p.m. to 10 p.m. from December 1 through February 28 during winter. The peak demand

savings and energy savings are calculated according to Equations below.

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑝𝑟𝑒 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑒𝑡𝑒𝑟𝑒𝑑

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑠𝑎𝑣𝑒𝑑 × 𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 Where:

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = The kilowatt savings realized during the year

𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑒𝑡𝑒𝑟𝑒𝑑= Spot Measured New Motor Demand, kW

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = The kilowatt-hour savings realized during the year

The Sponsor reports the peak demand and energy savings to CenterPoint Energy in the project

Savings Report.

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 65 -

9 Measurement Guidelines for Variable Speed Drives on

Constant Baseline Motor Measures

Overview Installing variable-speed drive (VSD) controllers on motors that serve a constant baseline load

requires a modified motor M&V procedure. Potential retrofit projects that might include VSDs

include:

Converting constant air volume (CAV) systems to variable air volume (VAV)

Retrofitting central chiller plants

Replacing standard efficiency electric motors with high efficiency models

Motors that are scheduled for the installation of VSDs follow the same Pre-Installation

Measurement Activities described in Chapter 7. If the efficiency of the existing motor is greater

than or equal to the minimum listed in the Table of Standard Motor Efficiencies, then the

baseline demand is equal to the spot measured value; if not, then it is calculated.

VSD measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

After the VSD and/or associated project retrofit has been installed, the Sponsor will again Post-

Installation Measurement Activities. The Post-installation equipment survey and the Post-

installation inspection procedures are the same as described earlier in this chapter.

After CenterPoint Energy has conducted a post-installation inspection and approved the project

Installation Report, the Sponsor should begin short-term metering1 of the power draw (kW) of

the motor/VSD combination (this accounts for the VSD demand/energy usage). The data must be

recorded at intervals of 15 minutes or less. However, averaged one-hour values are used in the

calculation of demand and energy savings. For calculating peak demand, the metering must

occur during one of the peak periods.

The duration of the metering period must be sufficient to capture the full range of motor

operation. If the motor load varies only daily and not seasonally, then a metering period of one

week is generally sufficient. If the motor load or operating hours vary with weather or other

seasonal parameters (e.g., production schedules, school calendars), then at least two weeks of

metering during each operating period is generally necessary. For example, if the motor serves

cooling equipment, then the metering should occur for at least two weeks during the winter

months and two weeks during the summer months.

The metering data are used to determine three values:

1 Long-term monitoring may be required for motors with non-uniform or unpredictable load patterns.

Program Manual v 18.1 Measurement Guidelines for Variable Speed Drives on Constant Baseline Motor Measures

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 66 -

Peak period demand (kW): Equal to the maximum-recorded peak period demand (one-hour

average values, where the summer peak period is defined as weekdays, between the hours of

1 PM and 7 PM, from June 1 through September 30 and the winter peak period is defined as

weekdays, from 6 AM to 10 AM and 6 PM to 10PM, from December 1 through February

28).

Average demand (kW): Equal to the average recorded demand. For motors with seasonal

load patterns, the average demand should be weighted according to the relative length of

each seasonal period (see VSD example).

Annual operating hours: Calculated from the metering data. For motors with seasonal load

patterns, the annual operating hours should be weighted according to the relative length of

each seasonal period.

For projects in which a large number of equal-sized motors with the same application and

operating schedule will be replaced, M&V may be conducted on a sample of the motors and the

results extrapolated to the applicable population. If this approach is adopted, the utility Program

Manager will select the motors to be metered.

The peak demand savings and energy savings are calculated according to Equations below: 𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑝𝑟𝑒 − 𝑘𝑊𝑝𝑒𝑎𝑘 𝑝𝑒𝑟𝑖𝑜𝑑

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = (𝑘𝑊𝑝𝑟𝑒 − 𝑘𝑊𝑝𝑜𝑠𝑡 𝑎𝑣𝑒) × 𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 Where:

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = The kilowatt savings realized during the year

𝑘𝑊𝑝𝑒𝑎𝑘 𝑝𝑒𝑟𝑖𝑜𝑑= Spot measured new motor demand in peak period, kW

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = The kilowatt-hour savings realized during the year

𝑘𝑊𝑝𝑜𝑠𝑡 𝑎𝑣𝑒= Measured averaged post-installation motor kW

HVAC Variable Frequency Drive (VFD) on Air Handler Unit (AHU)

Supply Fans deemed method This deemed method is applicable for the installation of VFDs on existing AHU supply fans.

This measure accounts for the interactive air-conditioning demand saving during the utility

defined peak period.

The baseline is a centrifugal supply fan with a single-speed motor, a direct expansion (DX) air

conditioning (AC) unit, and VAV boxes. The motor is a standard efficiency motor based on

ASHRAE Standard 90.1-2004 or other specific standards. The AC unit has standard cooling

efficiency based on IECC 2015. The part-load fan control is an outlet damper, inlet damper or

inlet guide vane.

The high efficiency condition is an installation of a VFD on an AHU supply fan. The existing

damper or inlet guide vane will be removed or set completely open permanently after

installation. The VFD will maintain a constant static pressure by adjusting fan speed and delivery

the same amount of air as the baseline condition. Deemed Demand and Energy Savings will be

calculated based on Appendix K.

10 Measurement Guidelines for Refrigeration Measures

Door Heater Controls This deemed method is applicable for the installation of Door Heater Controls for glass-door

refrigerated cases with anti-sweat heaters (ASH). A door heater controller senses dew point (DP)

temperature in the store and modules power supplied to the heaters accordingly. DP inside a

building is primarily dependent on the moisture content of outdoor ambient air. Because the

outdoor DP varies between climate zones, weather data from each climate zone must be analyzed

to obtain a DP profile. The reduced heating results in a reduced cooling load. The savings are on

a per-linear foot of display case basis.

Baseline efficiency case is a cooler or a freezer door heater that operates 8,760 hours per year

without any controls.

Eligible high efficiency equipment is a cooler or a freezer door heater connected to a heater

control system, which controls the door heaters by measuring the ambient humidity and

temperature of the store, calculating the dew point (DP) temperature, and using pulse width

modulation to control the anti-sweat door heater based on specific algorithms for freezer and

cooler doors. Deemed demand and Energy savings will be calculated based on Table 20 below.

ECM Evaporator Fan Motor This section presents the deemed savings methodology for the installation of an Electronically

Commutated Motor (ECM) in cooler and freezer display cases replacing existing evaporator fan

motors. ECMs can reduce fan energy use up to approximately 65%, and can also provide higher

efficiency, automatic variable-speed drive, lower motor operating temperatures, and less

maintenance.

All ECMs must constitute suitable, size-for-size replacements of evaporator fan motors. Baseline

efficiency case is an existing shaded pole evaporator fan motor in a refrigerated case. Eligible

high efficiency equipment is an electronically commutated motor which replaces an existing

evaporator fan motor. Deemed demand and Energy savings will be calculated based on Table 21

below. Table 21. Evaporator Fan Motor Deemed Savings

Electronic Defrost Controls This section presents the deemed savings methodology for the installation of electronic defrost

controls. The controls sense whether a defrost cycle is required in a refrigerated case, and skips it

if it is unnecessary.

The baseline efficiency case is an evaporator fan defrost system that uses a time clock

mechanism to initiate electronic resistance defrost. Eligible high efficiency equipment is an

evaporator fan defrost system with electronic defrost controls.

Evaporator Fan Controls This section presents the deemed savings methodology for the installation of evaporator fan

controls. As walk-in cooler and freezer evaporators often run continuously, this measure consists

of a control system that turns the fan on only when the unit’s thermostat is calling for the

compressor to operate.

Baseline efficiency case is an existing shaded pole evaporator fan motor with no temperature

controls, running 8,760 annual hours.

Eligible high efficiency equipment will be regarded as an energy management system (EMS) or

other electronic controls to modulate evaporator fan operation based on temperature of the

refrigerated space.

Night Covers for Open Refrigerated Display Cases This section presents the deemed savings methodology for the installation of night covers on

otherwise open vertical (multi-deck) and horizontal (or coffin-type) low-temperature and

medium-temperature display cases to decrease cooling load of the case during the night. It is

recommended that these film-type covers have small, perforated holes to decrease the build-up of

moisture.

Baseline efficiency case is an open low-temperature or medium-temperature refrigerated display

case (vertical or horizontal) that is not equipped with a night cover.

Eligible high efficiency equipment is considered any suitable material sold as a night cover. The

cover must be applied for a period of at least 6 hours per night. Vertical strip curtains may be in

use 24 hours per day.

Solid and Glass Door Reach-Ins This section presents the deemed savings methodology for the installation of ENERGY STAR®

or CEE certified Solid & Glass Reach-in doors for refrigerators and freezers, which are

significantly more efficient. The high-efficiency criteria, developed by ENERGY STAR® and

the Consortium for Energy Efficiency (CEE), relate the volume of the appliance to its daily

energy consumption. These reach-in cases have better insulation and higher-efficiency than save

energy, over regular refrigerators and freezers. The unit of measurement is volume in cubic feet

of the unit. The four most common sized refrigerators and freezers are reported here.

1. Sold- or glass-door reach-in refrigerators and freezers must meet CEE or ENERGY STAR®

minimum efficiency requirements

2. Baseline efficiency case is a regular refrigerator or freezer with anti-sweat heaters on doors

that meets federal standards.

3. Eligible high efficiency equipment for solid- or glass-door reach-in refrigerators and freezers

must meet CEE or ENERGY STAR® minimum efficiency requirements.

Strip Curtains for Walk-In Refrigerated Storage This measure refers to the installation of infiltration barriers (strip curtains or plastic swinging

doors) on walk-in coolers or freezers. These units impede heat transfer from adjacent warm and

humid spaces into walk-ins when the main door is opened, reducing the cooling load. This

results in a reduced compressor run-time, reducing energy consumption. This assumes that a

walk-in door is open 2.5 hours per day every day, and strip curtains cover the entire doorframe.

Strip curtains or plastic swinging doors installed on walk-in coolers or freezers.

Baseline efficiency case is a refrigerated walk-in space with nothing to impede air flow from the

refrigerated space to adjacent warm and humid space when the door is opened.

Eligible high efficiency equipment in a polyethylene strip curtain added to the walk-in cooler or

freezer. Any suitable material sold as a strip cover for a walk-in unit is eligible if it covers the

entire doorway.

Zero Energy Doors for Refrigerated Cases This section presents the deemed savings methodology for the installation of Zero Energy Doors

for refrigerated cases. These new zero-energy door designs eliminate the need for anti-sweat

heaters to prevent the formation of condensation on the glass surface by incorporating heat

reflective coatings on the glass, gas inserted between the panes, non-metallic spacers to separate

glass panes, and/or non-metallic frames.

This measure cannot be used in conjunction with anti-sweat heat (ASH) controls. It is not

eligible to be installed on cases above 0ºF.

Baseline efficiency case is a standard vertical reach-in refrigerated case with anti-sweat heaters

on the glass surface of the doors.

Eligible high efficiency equipment is the installation of special doors that eliminate the need for

anti-sweat heaters, for low-temperature cases only (below 0 ºF). Doors must have either heat

reflective treated glass, be gas-filled, or both.

Program Manual v 18.1 Measurement Guidelines for Application of Window Films

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 72 -

11 Measurement Guidelines for Application of Window

Films

Overview The installation of window films decreases the window shading coefficient and reduces the solar

heat transmitted to the building space. During months when perimeter cooling is required in the

building, this measure decreases cooling energy use.

The simplified M&V guidelines developed for this measure are applicable for window films

applied to south- and west-facing windows only. The measure demand and energy savings are

calculated based on the window-film area, change in shading coefficient, and cooling equipment

efficiency. Savings for window film measures are determined using the Window Film

Worksheet, available on the CenterPoint Energy C&I Standard Offer Program Web site at

https://centerpoint.anbetrack.com/.

The following steps comprise the simplified M&V procedure for window-film installations.

1. Collect data characterizing the existing south and west windows including: shading

coefficient, type of interior shading devices, and presence of exterior shading from buildings

or other obstacles. Identify the type and rated efficiency of the cooling equipment in the

building.

2. Document the installed window-film shading coefficient and window application area for the

south and west windows.

3. Based on the characteristics of the existing windows, newly installed window-films, and

cooling equipment; determine the annual demand and energy savings using the window-film

calculation spreadsheet.

Pre-Installation M&V Activities

11.2.1 Pre-Installation Site Survey

The goal of the pre-installation site survey is to identify the existing south and west window

characteristics. At a minimum, the surveys should include the following data for the south and

west windows:

Existing window description

Existing window shading coefficient

Window area by cardinal orientation

Description of interior shading devices

If applicable, an estimate of combined window-interior shading coefficient determined from

1997 ASHRAE Fundamentals, Chapter 29, Tables 24-29

Description of exterior shading

Description of building cooling equipment

This information will be included as part of the Project Application (PA). For window film

measures, the PA should be submitted after the project site has been identified. Submitting the

Program Manual v 18.1 Measurement Guidelines for Application of Window Films

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 73 -

PA prior to site identification could result in significant under or over estimation of savings since

variations in window area and shading characteristics between sites are large.

11.2.2 Pre-Installation Inspection

After the PA is submitted, CenterPoint Energy or its designee will conduct a pre-installation

inspection to verify that the Sponsor has properly documented the baseline characteristics of the

building, including window area by orientation, shading devices, and cooling equipment type.

The M&V administrator will inform the Project Sponsor of any necessary corrections to be made

to the pre-installation survey based on the results of the inspection. Removal or demolition of

existing shading devices and equipment or installation of new films, shading devices, and

equipment cannot commence until the pre-installation inspection is completed.

11.2.3 Installation Guidelines

Window film measures must be installed according to the manufacturer’s specifications.

Installed measures must also meet minimum electrical, fire, and health safety standards.

CenterPoint Energy will cancel any project whose installation fails to meet these requirements.

Post-Installation M&V Activities

11.3.1 Post-Installation Survey

The Sponsor should provide manufacturer’s data for the window films, specifically the National

Fenestration Rating Council (NFRC) shading coefficient for the installed window films. The area

of the window films applied for each different solar orientation must also be specified. These

data are required as part of the Installation Report (IR).

11.3.2 Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify the

documented characteristics of the building, windows, shading, cooling equipment, and window

films. The M&V administrator will inform the Project Sponsor of any necessary corrections to

be made to the pre-installation survey based on the results of the inspection. If the project is

comprised of many small installations, CenterPoint Energy will inspect a randomly selected

sample of the window-film installations completed by the Sponsor.

Calculation of Energy Savings The window film demand and energy savings result from a reduction in demand and energy use

of cooling equipment. Use the Window Film Worksheet to calculate savings. The savings

estimates rely on tabulated values of solar heat gain factors (SHGF) as published in the 1997

ASHRAE Fundamentals, Chapter 29, and Table 17. The ASHRAE data represent the amount of

solar radiation that is transmitted through single-pane clear glass for a cloudless day at 32o N

Latitude for the 21st day of each month by hour of day and solar orientation. The solar gain

values are translated to electric energy savings by considering the cooling equipment efficiency.

In the calculation, the cooling equipment efficiency equals the rated efficiency of the installed

equipment or the ASHRAE Standard 90.1-1989 minimum cooling equipment efficiency (see the

Standard Cooling Equipment Tables – Appendix I), whichever is more efficient.

To determine the coincident, peak summer demand savings associated with window films, the

highest, hourly, ASHRAE SHGF value that occurs during the summer peak period is identified

for each of the south and west building orientations. The available data nearest the CenterPoint

Energy service territory are presented in Table 22. The building demand savings are determined

from the maximum of these peak SHG values for the applicable window orientations.

To determine cooling energy savings associated with window films, the ASHRAE SHGF data

are aggregated into daily totals for weekdays during the months of April through October. These

totaled, SHG values are presented in Table 22. In the table, orientations that are symmetrical

relative to the southern sky have the same SHGF values.

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 76 -

12 Measurement and Verification for Generic Variable

Loads

Overview Projects that improve the efficiency of end-uses that exhibit variable energy demand or operating

hours may require continuous post-installation metering to measure and verify energy savings.

Examples of such projects include:

Upgrading building automation systems

Installing new industrial process equipment or systems

Comprehensive chiller plant modifications, including chillers, cooling towers, pumps, etc.

The use of continuous metering for measurement and verification (M&V) of variable loads

normally involves four steps:

1. Surveying the pre-installation system(s). As with all M&V methods, the Sponsor must audit

existing systems to document relevant components (e.g., piping and ductwork diagrams,

control sequences, and operating parameters).

2. Establishing a baseline model (e.g., an equation that determines energy use when key

independent variables are known). All, or a representative sample, of the existing systems

should be metered to establish regression-based equations or curves for defining baseline

system energy use as a function of appropriate variables (e.g., weather or cooling load).

Adjustments may be required for the models to comply with minimum energy efficiency

standards.

3. Monitoring post-installation energy use and/or independent variables e.g., weather.

Monitoring can be done continuously throughout a full year or for representative periods of

time during each performance year.

4. Determining the savings by subtracting the post-installation energy use from the baseline

energy use (as indicated in the baseline model).

Most energy retrofits can be monitored and savings verified using this method. However, there

are retrofits that cannot be quantitatively verified using continuous post-installation metering,

such as window tinting.

The M&V method described here is based on Option B of the 2007 International Performance

Measurement and Verification Protocol (IPMVP). Valuable insights on this method can be found

in the IPMVP.

Pre-Installation M&V Activities To establish the baseline operating characteristics of the existing systems, the following steps are

taken:

1. The Sponsor conducts a pre-installation equipment survey.

2. CenterPoint Energy and/or its designee conduct a pre-installation inspection.

3. The Sponsor conducts any necessary M&V activities.

4. The Sponsor develops a baseline energy consumption model based on metered system data.

CenterPoint Energy SECTION III - 77 -

12.2.1 Pre-Installation Equipment Survey

The Sponsor is required to conduct a pre-installation equipment survey, to be submitted as part

of the Project Application. The purpose of the pre-installation equipment survey is to inventory

all existing equipment to be affected by a project, and to propose the replacement equipment to

be installed. For each piece of equipment, the survey should list (as applicable): location,

manufacturer, model number, rated capacity, energy use factors (such as voltage, rated

amperage, MBtu/hr, fixture wattage), nominal efficiency, the load served, and any independent

variables that affect system energy consumption.

12.2.2 Pre-Installation Inspection

CenterPoint Energy or its designee will conduct a pre-installation inspection to verify that the

Sponsor has properly documented the baseline equipment. If significant errors are found in the

survey, CenterPoint Energy will inform the Sponsor that the submitted survey (which is a part of

the Project Application) must be corrected and resubmitted.

12.2.3 Pre-Installation Data Collection

Before making any efficiency modifications to existing equipment, the Sponsor must monitor the

following variables simultaneously:

Independent variables that affect energy use. Examples of such data are ambient

temperature, control outputs, flow rate, cooling tons, and building occupancy.

System energy consumption. Energy demand (e.g., kW) of the equipment to be affected by

the project metered over a representative time period sufficient to document the full range of

system operation.

Typically, metering observations should be made in 15-minute intervals, unless the Sponsor can

demonstrate that longer intervals are sufficient and CenterPoint Energy approves such intervals.

If multiple, identical equipment components or systems are to be modified (e.g., multiple heating

boilers), the M&V plan may specify metering of only a statistical sampling of the equipment.

In some cases, a dependent variable may serve as an accurate proxy for energy demand and may

be monitored in lieu of energy metering. Examples of dependent variables that may be used as a

proxy for energy include amperes and rotating equipment speed. If proxy variables are used, the

Sponsor must show that the proxy variable is representative of the actual demand.

12.2.4 Baseline Model Development

The energy use of most projects will be influenced by independent variables. For such projects, a

model must be developed (typically using regression techniques) that links independent-variable

data to energy use. The methodologies for creating such a model must be included in the Project

Application and approved by CenterPoint Energy.

The results of energy-input metering and variable(s) monitoring will be used to establish the pre-

installation relationship between these quantities. This relationship will be known as the “System

Baseline Model” and will probably be presented in the form of an equation. Regression analysis

is typically used to develop such an equation, although other mathematical methods may be

CenterPoint Energy SECTION III - 78 -

approved. If regression analysis is used, it must be demonstrated that that the model is

statistically valid.

The criteria for establishing statistical validity of the model are:

The model makes intuitive sense; e.g., the explanatory variables are reasonable, and the

coefficients have the expected sign (positive or negative) and are within an expected range

(magnitude).

The modeled data represent the population.

The model’s form conforms to standard statistical practice and modeling techniques for the

system in question.

The number of coefficients is appropriate for the number of observations.

The T-statistic for each term in the regression equation is equal to at least 2 (indicates with

95% confidence that the associated regression coefficient is not zero). The regression R2 is at

least 80%.

All data entered into the model are thoroughly documented and model limits (range of

independent variables for which the model is valid) are specified.

Raw data used in model development must be submitted with the Project Application or

Installation Report. CenterPoint Energy or its designee will make a final determination on the

validity of models and monitoring plans and may request additional documentation, analysis, or

metering as necessary.

12.2.5 Compliance with Energy Standards

The baseline model must comply with all applicable federal and state energy standards and

codes. If any existing equipment that will be part of the project does not meet the applicable

standards, the Sponsor must document how the baseline model will be adjusted to account for the

standards. It is possible that two baseline models will be developed – an existing system baseline

model and a minimum-standard system baseline model. In general, however, the M&V plan

should document how baseline values comply, or will be adjusted to comply, with the following:

Baseline equipment characterization should meet prescriptive efficiency standards

requirements for affected equipment

The baseline does not have to comply with performance compliance methods that require the

project site to meet an energy budget.

Demand and energy savings should be calculated with the incorporation of minimum state

and federal energy efficiency standards or codes into the determination of baseline energy

use.

12.2.6 Installation Guidelines

HVAC measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

CenterPoint Energy SECTION III - 79 -

Post-Installation M&V Activities To establish the post-installation operating characteristics of the affected systems, the following

steps are taken:

1. The Sponsor conducts a post-installation equipment survey.

2. CenterPoint Energy and/or its designee conduct a post-installation inspection.

3. The Sponsor conducts any necessary M&V activities.

12.3.1 Post-Installation Equipment Survey

The Sponsor is required to conduct a post-installation equipment survey to be submitted as part

of the Installation Report. The purpose of this equipment survey is to document the equipment

that was installed as part of a project. For each piece of equipment, the survey should list (as

applicable): location, manufacturer, model number, rated capacity, energy use factors (such as

voltage, rated amperage, MBtu/hr, wattage), nominal efficiency, the load served, and any

independent variables that affect system energy consumption.

12.3.2 Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

Sponsor has properly documented the installed equipment. After the inspection, CenterPoint

Energy will either accept or reject the Installation Report based on the inspection results and

project review.

12.3.3 Post-Installation Data Collection

After the retrofit, the Sponsor must monitor one or both of the following variables

simultaneously:

Independent variables that affect energy use. Examples of such data are ambient

temperature, control outputs, flow rate, cooling tons, and building occupancy.

System energy consumption. Energy demand (e.g., kW) of the equipment to be affected by

the project metered over a representative time period sufficient to document the full range of

system operation.

The variable(s) that must be monitored will depend on the savings calculation methodology used

for the retrofit, as described further in the next section. Note that the same guidelines for pre-

installation data collection should be followed for all post-installation data collection.

Calculation of Demand and Energy Savings There are two approaches for calculating demand and energy savings from generic variable load

projects. Both approaches require pre- and post-installation metering. The pre-installation

metering includes short-term measurements of equipment demand and metering of independent

variables. The pre-installation metering is necessary to develop the baseline energy use model.

For the post-installation monitoring, the first approach requires continuous metering of demand

and independent variables. The second approach relies on short-term measurements of demand

and continuous metering of independent variables. The two methods are summarized below.

Page 80: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification for Generic Variable Loads

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 80 -

1. Short-term, pre-installation metering of demand and independent variables to develop

baseline model. Continuous measurement of post-installation demand and the independent

variables used in the baseline model. Post-installation variable data are used with the baseline

model to calculate baseline energy use.

2. Short-term, pre-installation metering of demand and independent variables to develop

baseline model. Short-term, post-installation metering of demand and independent variables

to develop post-installation model. Continuous measurement of post-installation variables.

Post-installation variable data are used with the baseline and post-installation models to

calculate baseline and post-installation energy use.

12.4.1 First Approach: Metering Post-Installation Energy Use & Variables

To calculate energy savings using the first approach, the Sponsor will monitor demand and the

same independent variables that were used to develop the System Baseline Model after installing

the project. The Sponsor will then compare metered post-installation energy use with pre-

installation energy use as estimated by inputting the post-installation monitored independent

variables into the System Baseline Model. Demand and energy savings will be calculated using

the following equations:

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑝𝑟𝑒,𝑚𝑎𝑥 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = ∑(𝑘𝑊𝑝𝑟𝑒,𝑖– 𝑘𝑊𝑝𝑜𝑠𝑡−𝑚𝑒𝑎𝑠𝑢𝑟𝑒𝑑,𝑖)

𝑛

𝑖=1

Where:

𝑘𝑊𝑝𝑟𝑒,𝑚𝑎𝑥 = Maximum, pre-installation equipment demand occurring during utility peak

coincident load period

𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥 = Maximum, post-installation equipment demand occurring during utility peak

coincident load period

𝒌𝑾𝒑𝒓𝒆,𝒊= Baseline kW calculated from Baseline Model and corresponding to same time interval

𝒊, system output, weather, etc., conditions as 𝒌𝑾𝒑𝒐𝒔𝒕,𝒊

𝒌𝑾𝒑𝒐𝒔𝒕−𝒎𝒆𝒂𝒔𝒖𝒓𝒆𝒅,𝒊= Measured kW obtained through continuous or representative period, post-

installation metering

12.4.2 Second Approach: Metering Post-Installation Variables

To calculate energy savings using the second approach, the Sponsor must first develop a Post-

Installation System Model for use as a proxy for direct post-installation energy use measurement.

Then, the Sponsor monitors the relevant independent variables and uses that data to estimate

post-installation energy use. Note that the development of the Post-Installation System Model is

Page 81: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification for Generic Variable Loads

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 81 -

subject to the same requirements outlined for development of the Baseline System Model. Once

the post-installation energy use is estimated, energy savings over the course of a single

observation interval will be calculated using the following equations:

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑝𝑟𝑒,𝑚𝑎𝑥 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = ∑(𝑘𝑊𝑝𝑟𝑒,𝑖– 𝑘𝑊𝑝𝑜𝑠𝑡,𝑖)

𝑛

𝑖=1

Where:

𝑘𝑊𝑝𝑟𝑒,𝑚𝑎𝑥 = Maximum, pre-installation equipment demand occurring during utility peak

coincident load period

𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥 = Maximum, post-installation equipment demand occurring during utility peak

coincident load period

𝒌𝑾𝒑𝒓𝒆,𝒊= Baseline kW calculated from Baseline Model and corresponding to same time interval 𝒊, system

output, weather, etc., conditions as 𝒌𝑾𝒑𝒐𝒔𝒕,𝒊

𝑘𝑊𝑝𝑜𝑠𝑡,𝑖= Post-installation kW calculated from Post-Installation Model and corresponding to the

measured time interval; measured system output, measured weather variables, etc. in

the post-installation period

For a particular observation interval, the monitored data must be applied to the Baseline System

Model and to the Post-Installation Model to determine the baseline-system energy and post-

installation system energy input. The modeled-system post-installation is then subtracted from

the baseline energy input value. Energy savings are determined by multiplying this difference by

the length of the observation interval.

Project-Specific M&V Issues Specific M&V issues that need to be addressed for generic variable load projects include:

Determination of post-installation metering approach -- i.e., monitoring of energy use or

post-installation variables.

Modeling methodology for Baseline System Model(s) and Post-Installation Model (if used).

How minimum energy efficiency standards will be defined for the Baseline System Model?

Identification of appropriate variables.

Duration of baseline and post-installation monitoring.

13 Measurement and Verification Using Billing Analysis and

Regression Models

Overview Billing analysis involves the use of regression models with historical utility billing data (kW and

kWh) to calculate annual demand and energy savings. In general, billing analysis is used with

complex equipment retrofits and controls projects. Examples of the types of projects where

billing analysis may be employed include the installation of an energy management control

system (EMCS), and a comprehensive building retrofit involving multiple types of energy

efficiency measures (EEMs).

Billing analysis provides retrofit performance verification for projects where whole-facility

baseline and post-installation data are available. Billing analysis usually involves collection of

historical whole-facility baseline energy use data and a continuous measurement of the whole-

facility energy use after measure installation. Baseline and periodic inspections of the equipment

may also be warranted. Energy consumption is calculated by developing statistically

representative models (multivariate regression models) of historical whole-facility energy

consumption (kWh).

The M&V method described here is based, in part, on Option C of the 2001 International

Performance Measurement and Verification Protocol (IPMVP). Valuable insights on utility bill

analysis can be found in the IPMVP.

Baseline and Post-Retrofit Data Collection Collecting and validating data, as well as ensuring alignment of data start and end dates are

important elements of billing analysis. Data types and some data analysis protocols are discussed

below.

13.2.1 Data Types

As input to the multivariate regression models, billing data provide the basis for calibrating

models and post-installation energy use. Site data provide a means for controlling changes in

energy use not associated with measure installation. These data elements are discussed below.

Monthly Energy Billing Data. There are typically two types of monthly energy billing data;

total energy usage for the month, or energy usage aggregated by time-of-use periods. While

either type of data can be used with a regression model, time-of-use is preferable as it

provides more insight into usage patterns.

Interval Demand Billing Data. This type of billing data records the average demand for a

given interval (e.g., 15 minutes) associated with the billing period.

Site Data. Site data provide the information necessary to account for either changes in or

usage of energy consumption that is not associated with the retrofit equipment. Typical site

data that can be incorporated in regression models include weather parameters, occupancy,

facility square footage and operating hours. These data are typically used to help define the

independent variables that explain energy consumption or change associated with equipment

other than the equipment installed as part of an EEM.

Page 83: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification Using Billing Analysis and Regression Models

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 83 -

13.2.2 Data Analysis Protocols

The following are some of the required data analysis protocols:

Baseline Energy Consumption. This regression analysis requires at least 12 months’ worth

of data prior to the date of installation. However, if energy consumption is sensitive to

weather or other highly variable factors, then at least 24 months’ worth of data are required.

Post-installation Energy Consumption. This regression analysis requires at least nine

months, and preferably twelve months of data after the date of installation to determine

impacts for the first year.

Outliers. Outliers are data beyond the expected range of values (e.g., a data point more than

two standard deviations away from the average of the data). However, the elimination of

outliers should be explained. It is not sufficient to eliminate a data point because it is beyond

the expected range of values. If there is reason to believe that the data point is abnormal

because of specific mitigating factors, then it can be eliminated from the analysis.

Nevertheless, if a reason for the unexpected data point cannot be found, it should be included

in the analysis. Outliers should be defined based on “common sense” as well as common

statistical practice. Outliers can be defined in terms of consumption changes and actual

consumption levels.

Calculation of Energy Savings: Multivariate Regression Method Multivariate regression is an effective technique that controls for non-retrofit-related factors that

affect energy consumption. If the site data (all relevant explanatory variables, such as weather,

occupancy, and operating schedules) are available and/or collected, the technique should result in

more accurate and reliable savings estimates than a simple comparison of pre- and post-

installation energy consumption.

The use of the multivariate regression approach is dependent on and limited by the availability of

site and billing data. The decision to use a regression analysis technique should be based on the

availability of this information. Thus, on a project-specific basis, it is critical to investigate the

EEM dependent and independent variables that have direct relationships to energy use. Data

need to be collected for these variables in a suitable format over a significant period of time.

Separate models may be proposed that define pre-installation energy use and post-installation

energy use with savings equal to the difference between the two equations. It is assumed,

however, that a single “savings” model will be simpler and generate more reliable estimates

since it is also based on more data points.

13.3.1 Overview of the Regression Approach

Regression models should be developed that describe pre-installation and post-installation

energy use for the affected site (or sites), considering all explanatory variables.

For projects with time-of-use utility billing data, the regression models should yield savings by

hour or critical time-of-use period. For projects with only monthly consumption data, the models

should be used to predict monthly savings.

Page 84: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification Using Billing Analysis and Regression Models

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 84 -

13.3.2 Standard Equation for Regression Analysis

In the regression analysis, utility billing data (monthly or hourly) on a project-specific basis are

used to develop the models for comparing the pre-installation energy use to post-installation

energy use. After adjusting for non-retrofit-related factors in the models, the models’ energy use

difference is defined as the gross performance impact of the EEMs.

The regression equations should be specified to yield as much information as possible about

savings impacts. For example, with hourly data, it should be possible to estimate the savings

impacts by time of day, day of week, month, and year. With only monthly data, however, it is

only possible to determine the effects by month or year. Data with a frequency lower than

monthly should not be used under any circumstances.

13.3.3 Independent Variables

Independent variables that affect energy consumption should be specified for use in the

regression analysis. These variables can include weather, occupancy patterns, and operating

schedules.

If the multivariate regression models discussed above incorporate weather in the form of heating

degree-days (HDD) and/or cooling degree-days (CDD), the following issues must be considered:

The use of the building “temperature balance point” for defining degree-days versus an

arbitrary degree-day temperature base.

The relationship between temperature and energy use that tends to vary depending upon the

time of year. For example, a temperature of 55F in January has a different implication for

energy usage than the same temperature in August. Thus, seasonality should be addressed in

the model.

13.3.4 Testing Statistical Validity of Models

The statistical validity of the final regression model should be tested by the Sponsor and

CenterPoint Energy or its designee and should demonstrate the following:

The model makes intuitive sense; e.g., the independent variables are reasonable, and the

coefficients have the expected sign (positive or negative) and are within an expected range

(magnitude).

The modeled data are representative of the population.

The form of the model conforms to standard statistical practice.

The number of coefficients is appropriate for the number of observations (approximately no

more than one explanatory variable for every five data observations).

The T-statistic for all key parameters in the model is at least 2 (95% confidence that the

coefficient is not zero).

The model is tested for possible statistical problems and, if present, appropriate statistical

techniques are used to correct for them.

All data input to the model are thoroughly documented, and model limits (range of

independent variables for which the model is valid) are specified.

Program Manual v 18.1 Measurement and Verification Using Billing Analysis and Regression Models

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 85 -

13.3.5 Compliance with Energy Standards

When using billing analysis methods, the baseline should comply with minimum state and

federal energy standards with respect to the following:

Baseline equipment/systems should not include devices (e.g., lamps and ballasts) that are

not allowed to be installed under current regulations.

Baseline equipment should meet prescriptive efficiency standards requirements for

affected equipment.

Surveys and analysis correction methods (potentially outside of the model) should be

documented in a project-specific M&V plan.

The baseline does not have to comply with performance compliance methods that require

the facility to meet an energy budget.

13.3.6 Detailed Calculation Issues

The details of the savings calculations are dependent on such issues as:

The use of hourly versus monthly utility meter billing data

1 The format of the data (e.g., corresponding to same time interval as the billing data) and

availability of all relevant data for explanatory variables

2 The amount of available energy consumption data

3 The use of actual or typical data to calculate savings

4 Compliance with energy standards when calculating baseline energy use. Energy savings

should be calculated with the incorporation of minimum state and federal energy efficiency

standards or codes into the determination of baseline energy use.

Project Specific M&V Issues When billing analysis methods are used, the project specific M&V plan should address, in

addition to other topics generic to all M&V methods, the following:

How billing data covering an adequate period should be used to calculate savings in the performance year?

How the baseline will be adjusted to have the baseline meet minimum energy standards?

14 Measurement and Verification Using Calibrated

Simulation Analysis

Overview Computer Simulation Analysis for measurement and verification of energy savings is used when

the energy impacts of the energy efficiency measures (EEMs) are too complex1 or too costly to

analyze with traditional M&V methods. Situations where computer-based building energy

simulations may be appropriate include:

The EEM is an improvement or replacement of the building energy management or

control system.

There is more than one EEM and the degree of interaction between them is unknown or

too difficult or costly to measure.

The EEM involves improvements to the building shell or other measures that primarily

affect the building load (e.g., thermal insulation, low-emissivity windows).

Conducting simulation analysis is a time-consuming task. In some instances, the high costs of

conducting simulation analysis may not justify this type of M&V. Also, building simulation

software programs are not capable of modeling every conceivable building and equipment or

control EEM.

The M&V method described here is based, in part, on Option D of the 2001 International

Performance Measurement and Verification Protocol (IPMVP). Valuable insights on computer

simulation analysis can be found in the IPMVP.

The Sponsor should take the following steps in performing Computer Simulation Analysis

M&V:

1. Work with CenterPoint Energy and its designee to define a strategy for creating a calibrated

building simulation model in the project-specific M&V plan.

2. Collect the required data from utility bill records, architectural drawings, site surveys, and

direct measurements of specific equipment installed in the building.

3. Adapt the data and enter them into the program’s input files.

4. Run the simulation program for the “base” building model. The base building is the existing

building without the installed EEMs. The base building should comply with minimum state

and federal energy standards.

5. Calibrate the base model by comparing its output with measured data. The weather data for

the base model should be the actual weather occurring during the metering period. Refine the

base building model until the program’s output is within acceptable tolerances of the

measured data.

6. Run the calibrated base model using typical weather data to normalize the results.

Environment Conference.

CenterPoint Energy SECTION III - 87 -

7. Repeat the process for the post-installation model. Calibration of the retrofit model, if done,

should use data collected from site surveys (to validate that all the equipment and systems are

installed and operating properly) and possibly spot, short-term, or utility metering.

8. Estimate the savings. Savings are determined by subtracting the post-installation results from

the baseline results using typical conditions and weather. The savings estimates and

simulation results will be reviewed and verified by CenterPoint Energy or its designee.

These steps are described in more detail in the following sections.

Baseline and Post-Retrofit Data Requirements

14.2.1 Simulation Software

To conduct Calibrated Simulation Analysis M&V, it is recommended that the Sponsor use the

most current version available of the DOE-2.1E hourly building simulation program. For projects

with small projected incentive payments, the Sponsor may use other models if the model can be

shown to adequately model the project site and the EEMs, can be calibrated to a high level of

accuracy, and the calibration can be documented.

14.2.2 Weather Data

Calibrating a computer simulation of a real building for a specific year requires that actual

weather data be used in the analysis. Actual weather data should be collected from a source such

as National Climatic Data Center (NCDC) weather station data. The physical location of the

weather station should be the closest available to the project site. These data should be translated

into weather data files that are compatible with DOE-2. The project-specific M&V plan should

specify which weather data sources will be used.

Typical weather data used in the calculation of energy savings should be either Typical

Meteorological Year (TMY) or TMY2 data types, obtained from the National Renewable Energy

Laboratory (NREL).

Calculation of Energy Savings

14.3.1 Develop a Calibrated Simulation Strategy

The following are issues that either the Sponsor or CenterPoint Energy will need to address to

define the simulation approach:

Define the existing building. In general, the existing building represents the building, as it

exists prior to installation of EEMs by the Sponsor.

Define the baseline building. The baseline building represents the existing building but with

baseline equipment efficiencies as specified by state or federal standards.

Define the post-installation building. The post-installation building represents the building

with the project-related EEMs installed.

Define the calibration data interval. The building models should be calibrated using hourly,

daily or monthly data. Calibrations to hourly or daily data are preferred, since they are

Page 88: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 88 -

generally more accurate than calibrations to monthly data because there are more points to

compare. If monthly project site billing data are used, then spot or short-term data collection

for calibrated key values may be used.

Specify spot and short-term measurements to be taken of building systems. These

measurements augment the whole-building data and enable the modeler to accurately

characterize building systems. Spot and short-term measurements are valuable, but may add

significant cost and time to the project.

Employ an experienced building modeling professional. Although new simulation software

packages make much of the process easier, a program’s capabilities and real data

requirements are not fully understood by inexperienced users. Employing inexperienced

users for this purpose will result in inefficient use of time in data processing, and in checking

and understanding of simulation results.

14.3.2 Building Data Collection

The data required for simulating a real building are voluminous. The main categories of data to

be collected for the building and proposed EEMs are described below.

Building plans. The Sponsor should obtain as-built building plans. If as-built plans are not

available, the Sponsor should work with the building owner to define alternative sources.

Utility bills. The Sponsor should collect a minimum of twelve consecutive months (preferably 24

months), with applicable dates of utility bills for the months immediately before installation of

the EEMs. The billing data should include monthly kWh consumption and peak electric demand

(kW) for the month. Fifteen minute or hourly data are also desired for calibration. The Sponsor

should determine if building systems are sub-metered, and collect these data if available. If

hourly data are required to calibrate the simulation, but no data are available, metering

equipment may need to be installed to acquire hourly data.

Conduct on-site surveys. CenterPoint Energy or its designee will assist the Sponsor to identify

the necessary data to be collected from the building. The Sponsor should visit the building site to

collect the data. CenterPoint Energy or its designee may accompany the Sponsor during the

building survey. Data that may be collected include:

HVAC systems - primary equipment (e.g. chillers and boilers): capacity, number, model and

serial numbers, age, condition, operation schedules, etc.

HVAC systems - secondary equipment (e.g. air handling units, terminal boxes):

characteristics, fan sizes and types, motor sizes and efficiencies, design flow rates and static

pressures, duct system types, economizer operation and control

HVAC system controls, including location of zones, temperature set-points, control set-

points and schedules, and any special control features

Building envelope and thermal mass: dimensions and type of interior and exterior walls,

properties of windows, and building orientation and shading from nearby objects

Lighting systems: number and types of lamps, with nameplate data for lamps and ballasts,

lighting schedules, etc.

Plug loads: summarize major and typical plug loads for assigning values per zone

Building occupants: population counts, occupation schedules in different zones

Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 89 -

Other major energy consuming loads: type (industrial process, air compressors, water

heaters, elevators), energy consumption, schedules of operation, etc.

Interview operators. The Sponsor may choose to interview the building operator. Building

operators can provide much of the above listed information, and indicate if any deviation in

the intended operation of building equipment exists.

Make spot measurements. The Sponsor may find it necessary to record power draw on certain

circuits (lighting, plug load, HVAC equipment, etc.) to determine actual equipment operation

power.

Conduct short-term measurements. Data-logging monitoring equipment may be set up to record

system data as they vary over time. These data reveal how variable load data changes with

building operation conditions such as weather, occupancy, daily schedules, etc. These

measurements may include lighting systems, HVAC systems and motors. The period of

measurement should be from one to several weeks.

Obtain weather data. For calibration purposes, representative site weather data should be

obtained for a nearby NCDC site.

14.3.3 Base Building Simulation Models

Once all necessary information is collected, the Sponsor should input the simulation data into

DOE-2 code to create the base building model. The modeler should refine the model to obtain

the best representation of the base building. Where possible, the modeler should use measured

data and real building information to verify or replace the program’s default values.

Minimum Energy Standards

The baseline model should comply with minimum state and federal energy standards with

respect to the following:

Baseline equipment/systems models should not include devices (e.g. lamps and ballasts) that

are not allowed to be installed under current regulations.

Baseline equipment models should meet prescriptive efficiency standards requirements for

affected equipment.

Baseline calculations do not have to comply with performance compliance methods that

require the project site to meet an energy budget.

If the existing conditions of the EEMs do not comply with minimum state and federal standards,

the modeler should calibrate the simulation model with the building as it currently exists, and

then modify the existing building model to reflect the baseline efficiencies. This modified, or

baseline building is then used as the base case for computing energy savings.

Calibration

After the base building model has been created and debugged, the modeler should make a

comparison of the energy flows and demand projected by the model to that of the measured

utility data. All utility billing data should be used in the analysis, electric as well as heating fuels,

Page 90: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis

CenterPoint Energy SECTION III - 90 -

such as natural gas. The modeler may use either monthly utility bills, or measured hourly data to

calibrate the model when available.

The calibration process should be documented to show the results from initial runs and what

changes were made to bring the model into calibration. Statistical indices are calculated during

the calibration process to determine the accuracy of the model. If the model is not sufficiently

calibrated, the modeler should revise the parameters of the model and recalculate the statistics.

Hourly Data Calibration

In hourly calibration, two statistical indices are required to declare a model “calibrated”: monthly

mean bias error (MBE) and the coefficient of variation of the root mean squared error

(CV(RMSE))2.

𝑀𝐵𝐸 (%) =∑ (𝑀 − 𝑆)ℎ𝑟𝑚𝑜𝑛𝑡ℎ

∑ 𝑀ℎ𝑟𝑚𝑜𝑛𝑡ℎ × 100

𝐶𝑉𝐸 (𝑅𝑀𝑆𝐸𝑚𝑜𝑛𝑡ℎ) =√∑ (𝑀 − 𝑆)2

Where:

𝑀ℎ𝑟 = the measured kWh for any hour during the month

Monthly Data Calibration

Comparing energy use projected by simulation to monthly utility bills is straightforward. First

the model is developed and run using weather data that corresponds to the monthly utility billing

periods. Next monthly-simulated energy consumption and monthly measured data are plotted

against each other for every month in the data set. Equations below calculate the error in the

monthly and annual energy consumption. The acceptable tolerances for these values when using

monthly data calibration are shown in Table 24.

14.3.4 Post-Installation Models

After measure installation, a post-installation model can be prepared. The post-installation model

should usually be the baseline model with the substitution of new energy-efficient equipment and

systems. This new model should also be calibrated and documented. The possible calibration

mechanisms are:

Using site survey data to validate that all the specified equipment and systems are installed,

have the nameplate data used in the model, and are operating properly.

Using spot and/or short-term metering data to calibrate particular model modules of

equipment, systems or end-uses.

Using utility (15 minute, hourly or monthly) metering data to calibrate the model, as was

done with the pre-installation model.

The above mentioned post-installation model calibration mechanisms are not necessarily

mutually exclusive. If the first two mechanisms are used the model can be calibrated soon after

measure installation. If the last mechanism is used then the model can only be calibrated after

sufficient (e.g., 12 months) billing data are available.

In some instances, the post-installation model should be the only model calibrated. This can

occur when the baseline project site cannot be easily modeled due to significant changes during

the 12 months prior to the new measures being installed and thus the recent billing data are not

representative.

14.3.5 Detailed Energy Savings Calculations

Energy savings are determined from the difference between the outputs of the baseline and post-

installation models. Savings are determined with both models using the same conditions

(weather, occupancy schedules, etc.). To calculate savings, the energy consumption projected by

the post-installation model is subtracted from energy consumption projected by the baseline

model.

Program Manual v 18.1 Introduction to Measurement and Verification for New Construction Projects

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 93 -

This section includes detailed information about the measurement and verification (M&V)

requirements of the 2018 C&I Standard Offer Program, as well as guidance for Project Sponsors

on how to prepare and execute an M&V plan. These requirements and guidelines are specific to

New Construction projects.

15 Introduction to Measurement and Verification for New

Construction Projects

Overview In the 2018 C&I Standard Offer Program (SOP), the demand and energy savings resulting from a

project are determined through measurement and verification (M&V) activities. The M&V

methodology appropriate for any given project depends on the equipment type, operational

predictability, and project complexity.

Project Sponsors should use the M&V approaches presented here as the basis for developing a

methodology for measuring and verifying the demand and energy savings associated with their

projects. A Project Sponsor may recommend an alternative approach; however, any alternative

must be approved by CenterPoint Energy and adhere to the 2001 International Performance

Measurement and Verification Protocol (IPMVP), upon which these approaches are based

(except for deemed savings approaches, discussed below). Table 25 lists the available

measurement methods for the measures.

Table 25. Energy Efficiency Measure vs. Measurement Approach

Measurement Approaches The M&V guidelines provided in the following sections vary in detail and rigor, but fall into

three general categories:

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 94 -

The most appropriate approach depends on the availability of evaluation data from previous

programs for particular measures, the predictability of equipment operation, and the benefits of

the approach relative to the costs associated with that approach.

15.2.1 Deemed Savings

In deemed savings approaches, the demand and energy savings associated with particular

measures are based on values stipulated by CenterPoint Energy for factors such as operating

hours, efficiencies, and coincidence factors. These values result from analyses of evaluation data

from past demand-side management programs or other industry data. The deemed savings

approach is appropriate for equipment installations for which savings are relatively certain, such

as high-efficiency lamps or high performance windows. With deemed savings, the Project

Sponsor is not required to perform short-term testing or long-term metering.

15.2.2 Simplified M&V

A simplified M&V approach may involve short-term testing or simple long-term metering, but

relies primarily on manufacturer’s efficiency data and pre-established savings calculation

formulas. Simplified methods can reduce the need for some field monitoring or performance

testing. For example, the energy and demand savings associated with a high-efficiency constant

load motor are determined by comparing the rated efficiency of the specified, high-efficiency

motor to that of a standard motor, and then conducting spot-metering of the motor's demand and

long-term metering of the energy consumption.

CenterPoint Energy, or its designee, may collect the monitoring data onsite during the post-

installation inspection. In cases where this is necessary, the Sponsor is required to have any

logging equipment operational until the inspection takes place. It is the responsibility of the

Sponsor to have the required equipment or personnel to gather the data from any logging

equipment.

15.2.3 Full M&V

The full measurement approach estimates demand and energy savings using a higher level of

rigor than the deemed or metered measurement approaches through the application of computer

simulation. Any full measurement methods other than computer simulation should be developed

in accordance with the 2007 International Performance Measurement and Inspection Protocol

(IPMVP) and be approved by CenterPoint Energy. In general, projects involving full

measurement must submit a project-specific measurement plan. At a minimum, the plan should

address the following (from the 2007 IPMVP):

1. Describe the new construction project; include information on how the specified equipment

exceeds applicable standards.

2. Describe the Measurement method to be used.

3. Indicate who will conduct the Measurement activities and prepare the Measurement analyses

and documentation.

4. Define the details of how calculations will be made. For instance: “List analysis tools, such

as DOE-2 computer simulations, and/or show the equations to be used.” A complete “path”

CenterPoint Energy SECTION III - 95 -

should be defined indicating how collected survey and metering/monitoring data will be used

to calculate savings. All equations should be shown.

5. Specify what metering equipment will be used, who will provide the equipment, its accuracy

and calibration procedures. Include a metering schedule describing metering duration and

when it will occur, and how data from the metering will be validated and reported. Include

data formats. Electronic, formatted data read directly from a meter or data logger are

recommended for any short-or long-term metering.

6. Define what key assumptions will be made about significant variables or unknowns. For

instance: “actual weather data will be used, rather than typical-year data,” or “fan power will

be metered for one full year for two of the six supply air systems.” Describe any stipulations

that will be made and the source of data for the stipulations.

7. Define how any baseline adjustments will be made.

8. Describe any sampling method that will be used, what is included, sample size,

documentation on how sample size was selected, and information on how random sample

points will be selected.

9. Indicate how quality assurance will be maintained and replication confirmed.

16 Measurement Guidelines for Lighting Efficiency and

Controls

Overview The lighting projects covered by this M&V procedure are lighting efficiency measures that may

include the replacement of existing lamps and ballasts with new energy efficient lamps and

ballasts. For these types of projects, demand savings are based on coincident-load factors and

changes in lighting load as determined using standard lighting fixture wattage values listed in the

CenterPoint Energy Table of Standard Fixture Wattages (see Appendix H). To determine energy

savings, the Sponsor should establish operating hours using one of two methods:

Page 96: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement Guidelines for Lighting Efficiency and Controls

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 96 -

Deemed Hours – Operating hours have been established for certain building types (See

Table 16)

Metered Hours – Energy savings are determined by metering pre- or post-installation

operating hours using defined sampling techniques.

For lighting efficiency measures installed in electrically cooled spaces, demand and energy

savings are also given for lighting-HVAC system interaction. These savings are equal to various

percentages of the lighting demand savings and energy savings depending on the building types

and temperatures. Evaporative or alternate fuel system credits for electricity savings must be

based on Full M&V results.

In addition to determining operating hours, the Project Sponsor is required to conduct pre- and

post-installation equipment surveys. The Project Sponsor should fill out and submit survey

results in the New Construction Lighting Survey Form using fixture codes provided in the Table

of Standard Fixture Wattages. CenterPoint Energy or its designee will conduct a post-installation

inspection to verify the installation of the specified equipment.

Pre-Installation M&V Activities

16.2.1 Pre-Installation Equipment Survey

Prior to installing the lighting measures, the Project Sponsor prepares a pre-installation

equipment specification sheet by filling out a New Construction Lighting Survey Form. The

Project Sponsor submits this information as part of the Project Application. The pre-installation

equipment specification should provide the following information about all proposed fixtures:

room location, fixture, lamp, and ballast types, area designations, counts of fixtures, and type of

control device. Surveys should include all proposed lighting fixtures and controls. The Project

Sponsor must include estimates of the amount of lighting that will be provided by task lamps and

other moveable lighting sources. Fixture wattages are based on the fixture codes listed in the

Table of Standard Fixture Wattages. This information should be tabulated electronically in the

New Construction Lighting Survey Form. Once the Project Sponsor enters all fixtures into the

form, the form calculates what the building’s installed interior lighting load will be.

Some types of lighting fixtures are exempt from inclusion in the interior lighting demand

calculation. Project Sponsors should list exempt fixtures in the separate sheet provided in the

New Construction Lighting Survey Form. Exempt fixtures are fixtures that provide lighting that

is in addition to general, ambient lighting, have separate control devices, and are installed in one

of the following applications3:

Display or accent lighting that is an essential element for the function performed in galleries,

museums, and monuments.

Lighting that is integral to equipment or instrumentation and is installed by its manufacturer.

Lighting in retail display windows, provided the display area is enclosed by ceiling-height

partitions.

Lighting in interior spaces that have been specifically designated as a registered interior

historic landmark.

Lighting that is an integral part of advertising or directional signage.

Exit signs.

Lighting that is for sale or lighting educational demonstration systems.

Lighting for theatrical purposes, including performance, stage, and film and video

production.

Athletic playing areas with permanent facilities for television broadcasting.

Casino gaming areas.

16.2.2 Installation Guidelines

Lighting measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

Post-installation M&V Activities

16.3.1 Post-Installation Equipment Survey

The Project Sponsor is required to conduct a post-installation lighting equipment survey as part

of the Installation Report. The purpose of the post-installation equipment survey is to inventory

the actual, as-built equipment. Inventory information should be tabulated electronically in the

New Construction Lighting Survey Form. Fixture wattages shall be based on the Table of

Standard Fixture Wattages. Once the Project Sponsor enters all fixtures into the survey form, the

form calculates the buildings installed interior lighting load.

16.3.2 Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

measures were installed as reported. In most cases, CenterPoint Energy or its designee will

inspect statistically significant samples taken from the entire lighting population. The criterion

for acceptance is that the error in the installed demand of the sample must be within 10% of the

demand reported on the post-installation lighting equipment inventory form to avoid fees. Any

errors will be corrected in a revised Retrofit Lighting Survey Form.

CenterPoint Energy SECTION III - 98 -

16.3.3 Lighting Power Allowance

Demand savings are based on the difference between a project’s installed lighting loads,

compared to the maximum, code-specified lighting power allowance. To calculate the maximum

code-allowed lighting power allowance for a building, multiply the maximum lighting power

density for the appropriate building type, as listed in Table 27 and Table 28, by the gross lighted

floor area of the building. If a lighting measure is planned for a building type not listed in Table

27, choose the building type that is most similar in function. If a lighting measure is planned for

a building with mixed usages, e.g. a high rise building with retail space and office space, choose

the building type that represents the largest portion of the floor space.

16.4.2 Metered Hours

The Metered Hours Method involves monitoring a statistically significant sample of fixtures to

determine operating hours. This involves developing a sampling plan to monitor the average

operating hours for each lighting usage group. The Project Sponsor should conduct all meter

installation, retrieval and data analysis. When performing the post-installation activities

associated with this Measurement approach, Project Sponsors should organize the equipment

into usage groups—collections of equipment with similar operating schedules and functional

uses. For instance, although a site's open office lighting may have the same annual hours of

operation as the private office lighting, the two have different functional uses. In this case, a

change in the operating hours of the private office lights due to the installation of an occupancy

sensor would not be relevant to the operating hours of the open office lights. Therefore, private

offices and open office areas should be assigned to separate usage groups. Table 31 illustrates the

recommended minimum number of usage groups, specific to each project site.

Table 31. Suggested Minimum Numbers of Usage Groups for Project Site Types

Building Type

Usage Groups

Examples of Usage Group types

Retail Stores 5 Sales floor, storeroom, displays, private office, 24-hr

Manufacturing 6 Manufacturing, warehouse, shipping, offices, shops,

Other 10 N/A

The Project Sponsor will conduct short-term metering of the operating hours for a random

sample of fixtures in each usage group. For facilities with little variation in weekly operating

schedules (such as offices), monitoring shall be conducted for each selected circuit for a

recommended minimum of two to four weeks. Monitoring should not occur during significant

holidays or vacations. If a holiday or vacation falls within the monitoring period, the duration

should be extended for as many days as that holiday or vacation. For facilities where operating

hours vary seasonally, monitoring should be conducted for a minimum period during each

season. The required sample sizes for each usage group are listed in Table 32.

Note: because light loggers sometimes fail, over sampling is recommended. Light loggers should

be calibrated prior to installation to verify that the light loggers are functioning properly. If there

16.4.3 Calculation of Average Operating Hours

For each usage group, the Project Sponsor should extrapolate results from the monitored sample

to the population to calculate the average annual lighting operating hours. Simple, unweighted

averages of operating hours should be calculated for each usage group as listed in the following

equations. The Project Sponsor should use these average operating hours to calculate the energy

savings for each respective usage group.

16.4.4 Calculation of Average Co-Incidence Factor

The equation listed below illustrates the calculation of average on-peak demand coincidence

factor (CF) for a usage group. Note that demand savings are only allowed for lighting fixtures

that will be in operation on weekdays between the hours of 1 PM and 7 PM during the months of

June through September or from 6 AM to 10 AM and 6 PM to 10PM, from December 1 through

16.4.6 Metered Control Savings

If the project is ineligible for deemed savings and/or the Project Sponsor prefers to monitor

Operating Hours to claim achievable savings, the Metered Hours Method must be followed to

determine operating hours (Refer to Pages 7-9 of the 2007 International Performance

Measurement and Inspection Protocol). If the project involves the addition of lighting controls

to a building that does not fall under the deemed category and the stipulated method is

inadequate to determine pre-operating hours, then pre- and post-installation metering may be

required to determine pre- and post-operating hours.

17 Measurement Guidelines for High-Efficiency Cooling

Equipment

Overview Cooling equipment measures must involve the installation of equipment that exceeds current

energy efficiency standards. This chapter presents both a deemed savings approach and a

simplified approach to the measurement and verification of savings from the installation of high-

efficiency cooling equipment. High-efficiency equipment for which savings may be measured

using the methods described in this chapter includes:

Unitary air conditioners (DX, air-cooled, evaporative, or water-cooled)

Heat pumps (air-cooled, evaporative, or water-cooled)

Chillers (air-cooled centrifugal, water-cooled centrifugal, air-cooled screw)

Compressors (centrifugal, screw, reciprocating)

The projects should have the following characteristics:

Documented cooling load calculations for the affected facility.

The scope of the project for which incentives are requested is limited to individual pieces of

equipment, e.g. two 500-ton chillers, and not entire building systems.

If the proposed installation does not meet these requirements, refer to the Full Measurement

guidelines for appropriate Measurement techniques.

The applicable baseline efficiency values are from ASHRAE Standard 90.1-1999/2007/2010, or

IECC 2009; these values are provided in the Standard Cooling Equipment Tables in Appendix I

of this document. The applicable column in the Standard Cooling Equipment Tables is titled

“Minimum Performance Standard”.

Deemed Savings for Cooling Equipment The deemed savings approach to M&V for cooling equipment as part of new construction is

available to sponsors. The deemed savings methodology is incorporated in an Excel spreadsheet,

available to sponsors, which calculates savings values based on user inputs. The spreadsheet was

developed as a tool to assist sponsors with the deemed savings method. Manual calculations

using Equations below are acceptable as well.

Projects that are eligible to use the deemed savings approach must meet the following

requirements:

The existing and proposed cooling equipment are electric.

The Cooling Equipment is not used for process loads.

Coefficients are listed in Appendix I Table I.1 though Table I.8 for the type of building in

which the retrofit occurs and the type of equipment involved.

The building falls into one of the categories described in Table 34

17.2.1 Pre-Installation M&V Activities

Proof of Equipment Purchase

Sponsors must submit, within 30 days of the application approval, documentation showing the

new equipment is on order and should be delivered within the timeframe of the SOP.

Pre-Installation Site Survey

Prior to installing the cooling equipment measures, the Project Sponsor prepares a pre-

installation equipment specification sheet by filling out the deemed savings spreadsheet. The

deemed savings spreadsheet is available for downloading from the program Web site,

https://centerpoint.anbetrack.com/. The deemed savings spreadsheet requires the Project Sponsor

to input information about the equipment and the specified equipment’s type, size, make/model

and efficiency. The Project Sponsor submits the deemed savings spreadsheet as part of the

Project Application.

Pre-Installation Site Inspection

A pre-construction site inspection is generally not required, but in some cases – such as projects

involving additions to existing facilities – this inspection may be requested at CenterPoint

Energy’s discretion.

Installation Guidelines

HVAC measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

17.2.2 Post-Installation M&V Activities

Post-Installation Equipment Survey

Once the construction project is complete, the Project Sponsor revises the deemed savings

spreadsheet as necessary to reflect as-built conditions. An updated copy of the deemed savings

spreadsheet should be included with the Installation Report.

The Project Sponsor must submit manufacturer’s documentation of the rated efficiency of all

installed cooling equipment, based upon ARI test conditions. This documentation will be in the

form of manufacturer cut sheets or factory performance test results that document the full load

performance of the equipment.

Post-Installation Inspection

CenterPoint Energy or its designee will conduct a post-installation inspection to verify that the

equipment was installed as reported and is documented accurately.

Simplified M&V for Cooling Equipment The simplified M&V procedure for cooling equipment involves collecting one year of

consumption data after the project is complete. To determine demand savings for new electric

cooling equipment, the maximum demand that occurs during the utility peak hours must be

measured. This can be accomplished with continuous demand metering or spot metering during

peak conditions.

For gas engine-driven cooling equipment, the Sponsor must establish a “baseline” peak demand

and annual energy usage for a similarly sized electric chiller serving the exact same load. This

can be done two ways. The Sponsor can provide a year of measured data for a same size electric

chiller installed in an identical facility, or with a computer model. The same requirements for any

model discussed elsewhere in this manual apply in this case. The Sponsor must establish the

baseline to the satisfaction of CenterPoint Energy.

17.3.1 Pre-Construction M&V Activities

Proof of Equipment Purchase

Sponsors must submit, within 30 days of the application approval, documentation showing the

new equipment is on order and should be delivered within the timeframe of the program.

Equipment Survey

As part of the application process, the Project Sponsor provides an inventory of all specified

cooling equipment by filling out the Cooling Equipment Inventory Form, available for

downloading from the program Web site at https://centerpoint.anbetrack.com/. The information

provided should include:

equipment type

year

make/model

rated capacity

rated efficiency

operating schedule

operating sequence

Site Inspection

A pre-construction site inspection is generally not required, but in some cases—such as projects

involving additions to existing facilities—this inspection may be requested at CenterPoint

Energy's discretion.

Installation Guidelines

HVAC measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

CenterPoint Energy SECTION III - 112 -

17.3.2 Post-Installation M&V Activities

Equipment Survey

After construction is complete, the Project Sponsor provides an updated Cooling Equipment

Inventory Form to CenterPoint Energy as part of the Installation Report (IR). This survey must

include the same information itemized above, and be accompanied by a description of the

cooling equipment and its location as well as mechanical design drawings.

The Project Sponsor also submits manufacturer documentation of the rated efficiency of all

installed cooling equipment, based on ARI test conditions. This documentation should be in the

form of manufacturer cut sheets or factory performance test results that show the full load

performance of the equipment.

Site Inspection

Either CenterPoint Energy or its designee conducts a post-construction inspection to verify that

the specified equipment has been installed as reported and has been documented accurately.

Performance Monitoring

To verify the energy consumption (kWh) impacts of the higher efficiency cooling equipment, the

Project Sponsor collects consumption data, continuously, for a 12-month period. To verify the

impacts on demand (kW), the Project Sponsor measures demand for a one-hour period either

through continuous demand metering (at 15-minute intervals) or with spot measurements,

conducted between the hours of 1 PM and 7 PM on weekdays during the months of June through

September.

For electric-to-gas fuel switching cooling equipment, twelve months of post-installation gas

usage is required in the simple M&V procedure. In situations where the “baseline” equipment

and new construction equipment are not similar (water-cooled vs. air-cooled), the Sponsor must

account for the peak demand and annual energy usage of any auxiliary equipment.

17.3.3 Calculation of Demand and Energy Savings

High-efficiency Cooling Equipment

Project Sponsors can claim demand savings only for equipment that operates on weekdays

between the hours of 1 PM and 7 PM, Monday through Friday, during the months of June through

September.

Peak demand and energy savings are calculated according to Equations below.

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 × (𝐶𝑂𝑃𝑝𝑜𝑠𝑡

𝐶𝑂𝑃𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒− 1)

Full Measurement for Cooling Equipment The Full Measurement procedure for electric-to-electric cooling equipment replacement or

savings realized at the cooling equipment, due to control strategies, VAV modifications, building

shell improvements, etc, requires a building simulation. Any full measurement methods other

than computer simulation should be developed in accordance with the 2007 International

Performance Measurement and Inspection Protocol (IPMVP) and be approved by CenterPoint

Energy. Computer Simulation Analysis for measurement and verification of energy savings is

used when the energy impacts of the energy efficiency measures (EEMs) are too complex1 or too

costly to analyze with traditional M&V methods. Situations where computer-based building

energy simulations may be appropriate include:

The EEM is an improvement or replacement of the building energy management or control

system.

There is more than one EEM and the degree of interaction between them is unknown or too

difficult or costly to measure.

The EEM involves improvements to the building shell or other measures that primarily affect

the building load (e.g., thermal insulation, low-emissivity windows).

The M&V method described here is based, in part, on Option D of the 2007 International

Performance Measurement and Verification Protocol (IPMVP). Valuable insights on computer

simulation analysis can be found in the IPMVP. The Project Sponsor should take the following

steps in performing Computer Simulation Analysis M&V:

1. Work with CenterPoint Energy and its designee to define a strategy for creating a calibrated

building simulation model in the project-specific M&V plan.

2. Collect the required data from utility bill records, architectural drawings, site surveys, and

direct measurements of specific equipment installed in the building.

3. Adapt the data and enter them into the program’s input files.

4. Run the simulation program for the “base” building model. The base building is the existing

building without the installed EEMs. The base building should comply with minimum state

and federal energy standards.

5. Calibrate the base model by comparing its output with measured data. The weather data for

the base model should be the actual weather occurring during the metering period. Refine the

Environment Conference.

CenterPoint Energy SECTION III - 114 -

base building model until the program’s output is within acceptable tolerances of the

measured data.

6. Run the calibrated base model using typical weather data to normalize the results.

7. Repeat the process for the post-installation model. Calibration of the retrofit model, if done,

should use data collected from site surveys (to validate that all the equipment and systems are

installed and operating properly) and possibly spot short-term or utility metering.

8. Estimate the savings. Savings are determined by subtracting the post-installation results from

the baseline results using typical conditions and weather. The savings estimates and

simulation results will be reviewed and verified by CenterPoint Energy or its designee.

These steps are described in more detail in the following sections.

17.4.1 Baseline and Post-Retrofit Data Requirements

Simulation Software

To conduct Calibrated Simulation Analysis M&V, it is recommended that the Project Sponsor

use the most current version available of the DOE-2.1E hourly building simulation program. For

projects with small projected incentive payments, the Project Sponsor may use other models if

the model can be shown to adequately model the project site and the EEMs, can be calibrated to

a high level of accuracy, and the calibration can be documented.

Weather Data

Calibrating a computer simulation of a real building for a specific year requires that actual

weather data be used in the analysis. Actual weather data should be collected from a source such

as National Climatic Data Center (NCDC) weather station data. The physical location of the

weather station should be the closest available to the project site. These data should be translated

into weather data files that are compatible with DOE-2. The project-specific M&V plan should

specify which weather data sources will be used. Typical weather data used in the calculation of

energy savings should be either Typical Meteorological Year (TMY2) or TMY3 data types,

obtained from the National Renewable Energy Laboratory (NREL).

Develop a Calibrated Simulation Strategy

The following are issues that either the Project Sponsor or CenterPoint Energy will need to

address to define the simulation approach:

Define the baseline building. The baseline building represents the building with baseline

equipment efficiencies as specified by state or federal standards.

Define the post-installation building. The post-installation building represents the building

with the project-related EEMs installed.

Define the calibration data interval. The building models should be calibrated using

hourly, daily, or monthly data. Calibrations to hourly or daily data are preferred to monthly

data, since the former is more accurate than the latter, due to more comparison points. If

monthly project site billing data is used, then spot or short-term data collection for calibrated

key values may be used.

Specify spot and short-term measurements to be taken of building systems. These

measurements augment the whole-building data and enable the modeler to accurately

characterize building systems. Spot and short-term measurements are valuable, but may add

significant cost and time to the project.

Employ an experienced building modeling professional. Although new simulation

software packages make much of the process easier, a program’s capabilities and real data

requirements are not fully understood by inexperienced users. Employing inexperienced

users for this purpose will result in inefficient use of time in data processing, and in checking

and understanding of simulation results.

Building Data Collection

The main categories of data to be collected for the building and proposed EEMs are described

below.

Building plans. The Project Sponsor should obtain as-built building plans. If as-built plans

are not available, the Project Sponsor should work with the building owner to define

alternative sources.

Utility bills. The Project Sponsor should collect a minimum of twelve consecutive months

(preferably 24 months), with applicable dates of utility bills for the months immediately

before installation of the EEMs. The billing data should include monthly kWh consumption

and peak electric demand (kW) for the month. Fifteen minute or hourly data are also desired

for calibration. The Project Sponsor should determine if building systems are sub-metered,

and collect these data if available. If hourly data are required to calibrate the simulation, but

no data are available, metering equipment may need to be installed to acquire hourly data.

Conduct on-site surveys. CenterPoint Energy or its designee will assist the Project Sponsor

to identify the necessary data to be collected from the building. The Project Sponsor should

visit the building site to collect the data. CenterPoint Energy or its designee may accompany

the Project Sponsor during the building survey. Data that may be collected include:

HVAC systems - primary equipment (e.g. chillers and boilers): capacity, number, model

and serial numbers, age, condition, operation schedules, etc.

HVAC systems - secondary equipment (e.g., air handling units, terminal boxes):

characteristics, fan sizes and types, motor sizes and efficiencies, design flow rates and

static pressures, duct system types, economizer operation and control

HVAC system controls, including location of zones, temperature set-points, control set-

points and schedules, and any special control features

Building envelope and thermal mass: dimensions and type of interior and exterior walls,

properties of windows, and building orientation and shading from nearby objects

Lighting systems: number and types of lamps, with nameplate data for lamps and

ballasts, lighting schedules, etc.

Plug loads: summarize major and typical plug loads for assigning values per zone

Building occupants: population counts, occupation schedules in different zones

Other major energy consuming loads: type (industrial process, air compressors, water

heaters, elevators), energy consumption, schedules of operation, etc.

Interview operators. The Project Sponsor may choose to interview the building operator.

Building operators can provide much of the above listed information, and indicate if any

deviation in the intended operation of building equipment exists.

Make spot measurements. The Project Sponsor may find it necessary to record power draw

on certain circuits (lighting, plug load, HVAC equipment, etc.) to determine actual

equipment operation power.

Program Manual v 18.1 Measurement Guidelines for High-Efficiency Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 116 -

Conduct short-term measurements. Data-logging monitoring equipment may be set up to

record system data as they vary over time. These data reveal how variable load data changes

with building operation conditions such as weather, occupancy, daily schedules, etc. These

measurements may include lighting systems, HVAC systems and motors. The period of

measurement should be from one to several weeks.

Obtain weather data. For calibration purposes, representative site weather data should be

obtained for a nearby NCDC site.

Base Building Simulation Models

Once all necessary information is collected, the Project Sponsor should input the simulation data

into DOE-2 code to create the base building model. The modeler should refine the model to

obtain the best representation of the base building. Where possible, the modeler should use

measured data and real building information to verify or replace the program’s default values.

Minimum Energy Standards

The baseline model should comply with minimum state and federal energy standards with

respect to the following:

Baseline equipment/systems models should not include devices (e.g., lamps and ballasts) that

are not allowed to be installed under current regulations.

Baseline equipment models should meet prescriptive efficiency standards requirements for

affected equipment.

Baseline calculations do not have to comply with performance compliance methods that

require the project site to meet an energy budget.

If the existing conditions of the EEMs do not comply with minimum state and federal standards,

the modeler should calibrate the simulation model with the building as it currently exists, and

then modify the existing building model to reflect the baseline efficiencies. This modified, or

baseline building is then used as the base case for computing energy savings.

17.4.2 Calibration

After the base building model has been created and debugged, the modeler should make a

comparison of the energy flows and demand projected by the model to that of the measured

utility data. All utility billing data should be used in the analysis, electric as well as heating fuels,

such as natural gas. The modeler may use either monthly utility bills, or measured hourly data to

calibrate the model when available. The calibration process should be documented to show the

results from initial runs and what changes were made to bring the model into calibration.

Statistical indices are calculated during the calibration process to determine the accuracy of the

model. If the model is not sufficiently calibrated, the modeler should revise the parameters of the

model and recalculate the statistics.

Program Manual v 18.1 Measurement Guidelines for High-Efficiency Cooling Equipment

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 117 -

Hourly Data Calibration

In hourly calibration, two statistical indices are required to declare a model “calibrated”: monthly

mean bias error (MBE) and the coefficient of variation of the root mean squared error

(CV(RMSE))2. Equations related with the calculation of MBE and CV (RMSE) is listed below.

The acceptable tolerances for these values when using hourly data calibration are shown in Table

35.

𝑀𝐵𝐸 (%) =∑ (𝑀 − 𝑆)ℎ𝑟𝑚𝑜𝑛𝑡ℎ

∑ 𝑀ℎ𝑟𝑚𝑜𝑛𝑡ℎ × 100

Where:

𝑀ℎ𝑟 = the measured kWh for any hour during the month

𝑆ℎ𝑟 = the simulated kWh for any hour during the month

𝐶𝑉𝐸 (𝑅𝑀𝑆𝐸𝑚𝑜𝑛𝑡ℎ) =√∑ (𝑀 − 𝑆)2

ℎ𝑟 × 𝑁ℎ𝑟 𝑚𝑜𝑛𝑡ℎ

∑ 𝑀ℎ𝑟𝑚𝑜𝑛𝑡ℎ × 100

Where:

𝑆ℎ𝑟 = the simulated kWh for any hour during the month

𝑁ℎ𝑟 = the number of hours in the month

Monthly Data Calibration

Comparing energy use projected by simulation to monthly utility bills is straightforward. First

the model is developed and run using weather data that corresponds to the monthly utility billing

periods. Next monthly-simulated energy consumption and monthly measured data are plotted

against each other for every month in the data set. Equations calculating the error in the monthly

and annual energy consumption are given below. The acceptable tolerances for these values

when using monthly data calibration are shown in Table 36.

17.4.3 Post-Installation Models

After the measures are installed, a post-installation model can be prepared. The post-installation

model should usually be the baseline model with the substitution of new energy-efficient

equipment and systems. This new model should also be calibrated and documented. The possible

calibration mechanisms are:

Using site survey data to validate that all the specified equipment and systems are installed,

have the nameplate data used in the model, and are operating properly.

Using spot and/or short-term metering data to calibrate particular model modules of

equipment, systems or end-uses.

Using utility (15 minute, hourly, or monthly) metering data to calibrate the model, as was

done with the pre-installation model.

The above mentioned post-installation model calibration mechanisms are not necessarily

mutually exclusive. If the first two mechanisms are used the model can be calibrated soon after

measure installation. If the last mechanism is used then the model can only be calibrated after

sufficient (e.g., 12 months) billing data are available. In some instances, the post-installation

model should be the only model calibrated. This can occur when the baseline project site cannot

be easily modeled due to significant changes during the 12 months prior to the new measures

being installed and thus the recent billing data are not representative.

17.4.4 Detailed Energy Savings Calculations

Energy savings are determined from the difference between the outputs of the baseline and post-

installation models. Savings are determined with both models using the same conditions

(weather, occupancy schedules, etc.). To calculate savings, the energy consumption projected by

the post-installation model is subtracted from energy consumption projected by the baseline

model. Energy savings are calculated by the following equation.

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊ℎ𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 − 𝑘𝑊ℎ𝑝𝑜𝑠𝑡 Where:

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = The kilowatt-hour savings realized during the year.

𝑘𝑊ℎ𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒 =The kilowatt-hour consumption of the baseline building operating under the same

conditions (weather, operation and occupancy schedules, etc.) as the post-

installation building.

𝑘𝑊ℎ𝑝𝑜𝑠𝑡 = The kilowatt-hour consumption of the post-installation building operating under the

same conditions (weather, operation and occupancy schedules, etc.) as the baseline

building.

CenterPoint Energy SECTION III - 119 -

18 Measurement Guidelines for Constant Load Motor

Measures

Overview This chapter presents the simplified M&V approach for projects involving the installation of

constant load motors with efficiency ratings higher than those required by the applicable energy

efficiency standard. Examples of qualifying equipment include:

Constant load chilled water, hot water, or condenser water pumps

Constant speed exhaust, return, and supply fans without dampers or pressure controls

Single-speed cooling tower fans

Constant load industrial processes

Similar capacity, constant speed, energy efficiency motors

Project Sponsors should not use this approach if factors utilized to derive savings vary

throughout the year. Examples may include schedule changes and load changes.

If the project does not meet the above requirements, please refer to Chapter 7 for the appropriate

M&V approach.

Demand and energy savings for motor installations are based on post-construction peak demand

(kW), the motor operating hours, and the difference in efficiency between baseline and higher-

efficiency motors.

The peak demand period is defined as weekdays, between the hours of 1 PM and 7 PM, from June

1 through September 30 (excluding holidays) or weekdays, from 6 AM to 10 AM and 6 PM to

10PM, from December 1 through February 28. The operating hours are assumed to be the same

for both baseline and higher-efficiency motors.

Prescriptive incentives are available for the installation of premium efficiency motors.

Savings values can be obtained by completing the Premium Efficiency Motor Form.

Baseline motor efficiencies are listed in the Standard Motor Table in Appendix J of this

document, which is based on ASHRAE Standard 90.1m-1995. The Standard Motor Table is

categorized by motor size and rotation speed. The baselines for motors whose efficiencies are not

listed in the table will be determined on a case-by-case basis by CenterPoint Energy. The project

sponsor must provide demonstrable proof that energy efficiency was a key criterion in the motor-

selection process to qualify for incentives. No incentive payments are made for replacement

motors with efficiencies equal to or less than the baseline efficiency. In addition to having a

higher efficiency than baseline motors, all new motors should meet minimum equipment

standards as defined by state and federal law.

Pre-Construction Activities

18.2.1 Equipment Survey

Project Sponsors should use the Motor and VSD Inventory form to record the following

information for each specified high-efficiency motor:

Motor name

Load served

Motor location

Operating schedule

Equipment manufacturer

Nameplate data including model, horsepower, and speed

18.2.2 Site Inspection

A pre-construction site inspection is generally not required, but in some cases—such as projects

involving additions to existing facilities—this inspection may be requested at CenterPoint

Energy's discretion.

18.2.3 Installation Guidelines

Motor measures must be installed according to the manufacturer’s specifications. Installed

measures must also meet minimum electrical, fire, and health safety standards. CenterPoint

Energy will cancel any project whose installation fails to meet these requirements.

Post-Construction Activities

18.3.1 Equipment Survey

The Project Sponsor provides a post-construction equipment survey, similar to the pre-

construction equipment survey, to CenterPoint Energy as part of the Installation Report. The

updated Motor and VSD Inventory Form reflects the actual, as-built conditions of the project.

18.3.2 Motor Demand Measurement

The Project Sponsor performs spot measurements of the power draw (one-hour average values)

of all the high-efficiency motors installed, and includes these measurements in the Installation

Report.

18.3.3 Calculation of Baseline Motor Demand

Equation below is used to determine what the demand would have been had a lower efficiency

motor been specified for installation.

𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑= spot measured existing motor demand, kW

18.3.4 Site Inspection

After CenterPoint Energy receives an Installation Report, either CenterPoint Energy or its

designee conducts a post-construction site inspection to verify that the equipment specifications

have been correctly reported by the Project Sponsor in the Installation Report. CenterPoint

Energy will require the Project Sponsor to make any necessary corrections to the Installation

Report based on the results of the inspection.

Calculation of Motor Operating Hours After CenterPoint Energy approves the Installation Report, the Project Sponsor begins short-term

metering of motor operating hours. The metering must be conducted for a minimum period of

one week, or an amount of time sufficient to capture the full range of operation. Equation below

is used to calculate the annual operating hours using the metered data.

𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 =𝐻𝑜𝑢𝑟𝑠𝑜𝑛

𝐻𝑜𝑢𝑟𝑠𝑚𝑒𝑡𝑒𝑟𝑒𝑑× 8760

Where:

𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙 = average annual operating hours

𝐻𝑜𝑢𝑟𝑠𝑜𝑛 = operating hours observed during the metering period

𝐻𝑜𝑢𝑟𝑠𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = total number of hours in the metering period

Calculation of Peak Demand and Energy Savings Project Sponsors can claim demand savings only for equipment that operates on weekdays

between the hours of 1 PM and 7 PM, Monday through Friday, from June 1 through September 30

(excluding holidays).

Peak demand and energy savings are calculated according to Equations below.

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑝𝑟𝑒 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑒𝑡𝑒𝑟𝑒𝑑

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑠𝑎𝑣𝑒𝑑 × 𝐻𝑜𝑢𝑟𝑠𝑎𝑛𝑛𝑢𝑎𝑙

Where:

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = The kilowatt savings realized during the year

𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑒𝑡𝑒𝑟𝑒𝑑= Spot Measured New Motor Demand, kW

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = The kilowatt-hour savings realized during the year

The Sponsor reports the peak demand and energy savings to CenterPoint Energy in the project

Savings Report.

CenterPoint Energy SECTION III - 124 -

20 Measurement and Verification for Generic Variable

Loads

Overview High-efficiency end-use systems that exhibit variable energy demand or operating hours may

require continuous metering to measure and verify energy savings. Examples of such projects are

constructions that involve:

building automation systems

industrial process equipment or systems

chiller plant optimization, including chillers, cooling towers, pumps, etc.

The use of continuous metering for measurement and verification (M&V) of variable loads

normally involves four steps:

1. Reviewing the pre-construction system(s). As with all M&V methods, the Project Sponsor

must review plans and specifications to document relevant components (e.g., piping and

ductwork diagrams, control sequences, and operating parameters).

2. Establishing a baseline model (e.g., an equation that determines energy use when key

independent variables are known). All, or a representative sample, of the systems should be

modeled to establish regression-based equations or curves for defining baseline system

energy use as a function of appropriate variables (e.g., weather or cooling load).

3. Monitoring energy use and/or independent variables such as weather. Monitoring can be

done continuously throughout a full year or for representative periods of time during each

performance year.

4. Determining the savings by subtracting the post-construction energy use from the baseline

energy use (as indicated in the baseline model).

The M&V method described here is based on Option B of the 2007 International Performance

Measurement and Verification Protocol (IPMVP). More details on this method can be found in

the IPMVP.

Documenting Baseline Characteristics To establish the baseline characteristics of the new-construction systems, the following steps are

taken:

1. The Project Sponsor conducts a pre-construction equipment inventory.

2. Either CenterPoint Energy or its designee conducts a pre-construction inspection, if

necessary.

3. The Project Sponsor develops a baseline energy consumption model.

20.2.1 Pre-Construction Equipment Survey

The Project Sponsor is required to conduct a pre-construction equipment survey, which is part of

the Project Application. The equipment survey itemizes all specified equipment involved in the

Page 125: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification for Generic Variable Loads

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 125 -

project. For each piece of equipment, the survey should list (as applicable) the location,

manufacturer, model number, rated capacity, energy use factors (such as voltage, rated

amperage, MBtu/hr, fixture wattage), nominal efficiency, load served, and any independent

variables that affect system energy consumption.

20.2.2 Pre-Construction Inspection

A pre-construction site inspection is generally not required, but in some cases—such as projects

involving additions to existing facilities—this inspection may be requested at CenterPoint

Energy's discretion

.

20.2.3 Installation Guidelines

Measures must be installed according to the manufacturer’s specifications. Installed measures

must also meet minimum electrical, fire, and health safety standards. CenterPoint Energy will

cancel any project whose installation fails to meet these requirements.

20.2.4 Baseline Model Development

The energy use of most projects is influenced by independent variables. For such projects, the

Project Sponsor must develop a model (typically using regression techniques) that links

independent-variable data to energy use. The Project Sponsor must include an explanation of the

methodologies used for creating such a model in the Project Application for CenterPoint

Energy's review.

Project Sponsors should use manufacturer-supplied performance data for equipment that meets

the minimum requirements of code to establish a relationship between independent variables and

energy use. This relationship is known as the “Baseline System Model” and will likely take the

form of an equation. Regression analysis is typically used to develop such an equation, although

other mathematical methods may be approved. If regression analysis is used, it must be

demonstrated that that the model is statistically valid.

The criteria for establishing statistical validity of the model are:

The model makes intuitive sense; that is, the explanatory variables are reasonable, and the

coefficients have the expected sign (positive or negative) and are within an expected range

(magnitude).

The modeled data represent the population.

The model’s form conforms to standard statistical practice and modeling techniques for the

system in question.

The number of coefficients is appropriate for the number of observations.

The T-statistic for each term in the regression equation is equal to at least 2 (indicates with

95% confidence that the associated regression coefficient is not zero). The regression R2 is at

least 80%.

All data entered into the model are thoroughly documented and model limits (range of

independent variables for which the model is valid) are specified.

The Project Sponsor includes the data used in model development in the Project Application or

Installation Report. Either CenterPoint Energy or its designee makes a final determination on the

Page 126: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification for Generic Variable Loads

CenterPoint Energy SECTION III - 126 -

validity of models and monitoring plans and may request additional documentation, analysis, or

metering.

20.2.5 Compliance with Energy Standards

The baseline model must comply with all applicable federal and state energy standards and

codes. If any existing equipment that will be part of the project (as may be the case in a new-

construction addition to an existing building) does not meet the applicable standards, the Project

Sponsor must document how the baseline model will be adjusted to account for the standards. In

general, however, the M&V plan should document that the

Baseline equipment characterization meets prescriptive efficiency standards requirements for

affected equipment (e.g., ASHRAE Standard 90.1).

Baseline need not comply with performance compliance methods that require the project site

to meet an energy budget.

Minimum state and federal energy efficiency standards or codes must be incorporated into

the baseline.

Documenting Post-Construction Characteristics When construction is complete, the following steps are taken:

1. The Project Sponsor updates the equipment inventory.

2. Either CenterPoint Energy or its designee conducts an inspection.

3. The Project Sponsor conducts any necessary data collection.

20.3.1 Post-Construction Equipment Survey

The Project Sponsor is required to conduct a post-construction equipment survey to be submitted

as part of the Installation Report. This equipment survey documents the equipment that was

installed. For each piece of equipment, the survey should list (as applicable) the location,

manufacturer, model number, rated capacity, energy use factors (such as voltage, rated

amperage, MBtu/hr, wattage), nominal efficiency, load served, and any independent variables

that affect system energy consumption.

20.3.2 Post-Construction Inspection

Either CenterPoint Energy or its designee conducts an inspection to verify that the Project

Sponsor has properly documented the installed equipment. After the inspection, CenterPoint

Energy either accepts or rejects the Installation Report based on the inspection results and project

review.

20.3.3 Post-Construction Data Collection

The Project Sponsor must monitor one or both of the following variables simultaneously:

Independent variables that affect energy use. Examples of such data are ambient

temperature, control outputs, flow rate, cooling tons, and building occupancy.

System energy consumption. Energy demand (kW) of installed equipment, metered over a

time period representative of the full range of system operation.

The variable(s) monitored depend on the variable(s) modeled in the Baseline System Model.

Calculation of Demand and Energy Savings There are two approaches for calculating demand and energy savings from generic variable load

projects. Both approaches require baseline modeling (as previously discussed) and post-

construction metering.

The first approach requires continuous metering of demand and the independent variables used

in the baseline model. Post-construction variable data are used with the baseline model to

calculate baseline energy use.

The second approach involves developing a post-construction model from short-term metering of

demand and continuous metering of independent variables. Data from continuous metered post-

construction variables are then used in the baseline and post-construction models to calculate

baseline and post-construction energy use.

20.4.1 First Approach: Metering Post-Construction Energy Use and Variables

To calculate energy savings using the first approach, the Project Sponsor monitors demand and

the same independent variables that were used for the System Baseline Model. The Project

Sponsor then inputs the post-construction independent variable data to the System Baseline

Model and compares post-construction energy use with baseline energy use. Demand and energy

savings, over a single observation interval, are calculated using Equations below.

𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑏𝑎𝑠𝑙𝑖𝑛𝑒,𝑚𝑎𝑥 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥

𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = ∑(𝑘𝑊𝑏𝑎𝑒𝑙𝑖𝑛𝑒,𝑖– 𝑘𝑊𝑝𝑜𝑠𝑡−𝑚𝑒𝑎𝑠𝑢𝑟𝑒𝑑,𝑖)

𝑛

𝑖=1

Where:

𝑘𝑊𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒,𝑚𝑎𝑥 = maximum baseline equipment demand occurring during utility peak coincident

load period

𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥 = maximum, post-installation equipment demand occurring during utility peak

coincident load period

system output, weather, etc., conditions as 𝒌𝑾𝒑𝒐𝒔𝒕,𝒊

𝒌𝑾𝒑𝒐𝒔𝒕−𝒎𝒆𝒂𝒔𝒖𝒓𝒆𝒅,𝒊= measured kW obtained through continuous, or representative period, post-installation

metering

20.4.2 Second Approach: Metering Post-Construction Variables

To calculate energy savings using the second approach, the Project Sponsor must first develop a

Post-Construction System Model for use as a proxy for direct post-construction energy use

measurement. Then, the Project Sponsor monitors the relevant independent variables and uses

that data to estimate post-construction energy use. Once the post-construction energy use is

estimated, energy savings over the course of a single observation interval will be calculated

using the following Equations below.

𝑘𝑊𝑝𝑜𝑠𝑡,𝑖= Post-installation kW calculated from Post-Installation Model and corresponding to the

measured time interval; measured system output, measured weather variables, etc. in

the post-installation period

For a particular observation interval, the monitored data must be applied to the Baseline System

Model and to the Post-Construction System Model to determine the baseline-system energy and

post-construction system energy input. The modeled-system post-construction is then subtracted

from the baseline energy input value. Energy savings are determined by multiplying this

difference by the length of the observation interval.

Project-Specific M&V Issues Specific M&V issues that need to be addressed for generic variable load projects include:

Determination of post-construction metering approach—i.e., metering of energy use or post-

construction variables.

Modeling methodology for Baseline System Model and Post-Construction Model (if used).

Identification of appropriate independent variables.

Duration of post-construction metering.

CenterPoint Energy SECTION III - 129 -

21 Measurement and Verification Using Calibrated

Simulation Analysis

Overview This section outlines the use of computer simulation analysis for measurement and verification

of new construction energy savings. Computer simulation analysis should be used when the

energy impacts of the energy efficiency measures are too complex6 or too costly to analyze with

traditional M&V methods. Computer-based building energy simulations are appropriate for

constructions in which

A building energy management or control system is specified

The degree of interaction among multiple measures is either unknown or too difficult or

costly to measure.

The measures involve improvements that primarily affect building load—e.g., thermal

insulation, low-emissivity windows

Conducting simulation analysis is often a time-consuming and expensive task, and the costs

associated with this approach may be prohibitive in some instances. Also, building simulation

software programs are not always capable of modeling every type or combination of energy

efficiency measures.

The approach described here is based, in part, on Option D of the 2001 International

Performance Measurement and Verification Protocol (IPMVP). More information on computer

simulation analysis can be found in the IPMVP. This approach requires that the Project Sponsor:

1. Work with CenterPoint Energy to define a strategy for creating a calibrated building

simulation model in the project-specific M&V plan.

2. Collect the required data from architectural drawings, mechanical plans, equipment

schedules, and equipment submittals.

3. Adapt the data and enter them into the program’s input files.

4. Run the simulation program for the “as-built” high-performance building model. The “as-

built” building is the newly constructed building with all energy efficiency measures

installed.

5. Calibrate the model by comparing its output with measured data. The weather data for the

model should be the actual weather occurring during the metering period. Refine the model

until the program’s output is within acceptable tolerances of the measured data.

6. Run the calibrated as-built model using typical weather data to normalize the results.

7. Repeat the process for the baseline building model. The baseline building model is the newly

constructed building with specifications that reflect applicable minimum performance values

(from ASHRAE 90.1 1999 or from the minimum state and federal energy standards,

whichever are more efficient).

Environment Conference.

CenterPoint Energy SECTION III - 130 -

8. Calculate the savings by subtracting the as-built results from the baseline results. CenterPoint

Energy reviews and verifies the savings estimates and simulation results. These steps are

described in more detail in the following sections.

Software Selection CenterPoint Energy recommends that the Project Sponsor use the most current version available

of the DOE-2.1E hourly building simulation program. For projects with small projected incentive

payments, the Project Sponsor may use another program, provided that the program can be

shown to adequately model the building, the system or equipment installations can be calibrated

to a high level of accuracy, and the calibration can be documented.

Developing a Calibrated Simulation Strategy A sound approach to measuring and verifying your savings using computer simulation analysis

must include the activities listed below. The Project Sponsor and CenterPoint Energy should

confer on the best approach to each activity.

Employ an experienced building modeling professional. Although new simulation software

packages make much of the process easier, a program’s capabilities and real data

requirements are not fully understood by inexperienced users. Employing an experienced

modeler can save a significant amount of time.

Define the baseline building. In general, the baseline building represents the building, as it

would have been built, had minimum standard equipment been installed instead of the high-

efficiency equipment.

Define the as-built building, which represents the building as it was constructed, with all the

installed high-efficiency equipment and systems.

Define the calibration interval. The as-built model should be calibrated using hourly, daily, or

monthly data. Calibrations to hourly or daily data are preferred because there are more data

points to compare. If monthly billing data are used, then spot or short-term data

measurements for calibrated key values may be used.

Specify spot and short-term measurements to be taken of building systems. These

measurements augment the whole-building data and enable the modeler to accurately

characterize building systems. Spot and short-term measurements are valuable, but may add

significant cost and time to the project.

Data Collection The volume of data required for simulating a real building is significant. The Project Sponsor

needs to collect data from the following sources:

As-built building plans. The Project Sponsor should work with the building owner to gather

as-built building plans.

Utility bills. The Project Sponsor should collect utility bills for a minimum of twelve

consecutive months following construction. The billing data should include monthly

consumption (kWh) and peak electric demand (kW), preferably in fifteen-minute or hourly

intervals (for optimal calibration). If interval data are not available, the Project Sponsor may

need to arrange for the installation of metering equipment to collect the necessary data. Also,

Page 131: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION III - 131 -

the Project Sponsor should determine if building systems are sub-metered, and collect these

data if available.

Conduct on-site surveys and reviews of mechanical plans. CenterPoint Energy helps the

Project Sponsor establish which data must be collected. The Project Sponsor should visit the

site to verify the accuracy of the mechanical plan data. CenterPoint Energy may accompany

the Project Sponsor during this survey. Depending on the project, the Project Sponsor should

collect data for

primary HVAC equipment (e.g. chillers and boilers): capacity, number, model and serial

numbers, operation schedules

secondary HVAC equipment (e.g., air handling units, terminal boxes): fan sizes and

types, motor sizes and efficiencies, design flow rates and static pressures, duct system

types, economizer operation and control

HVAC controls, including the location of zones, temperature set-points, control set-

points and schedules, and any special control features

building envelope and thermal mass: dimensions and type of interior and exterior walls,

properties of windows, and building orientation and shading

lighting systems: number and types of lamps, with nameplate data for lamps and ballasts,

lighting schedules

plug loads: summarize major and typical plug loads for assigning values per zone

occupancy: population counts, occupation schedules in different zones

other major energy consuming loads: type (industrial process, air compressors, water

heaters, elevators), energy consumption, schedules of operation.

Interview operators. Building operators can provide much of the above listed information

and can also inform on any deviation in the intended operation of equipment.

Make spot measurements. To determine the actual power draw of operating equipment, the

Project Sponsor may find it necessary to meter certain circuits (lighting, plug load, HVAC

equipment).

Conduct short-term measurements. Data-logging equipment may be set up to record

system data as they vary over time. These measurements may involve lighting systems,

HVAC systems, and motors. The period of measurement should be from one to several

weeks.

Obtain weather data. Calibrating a computer simulation of a real building for a specific

year requires the use of actual weather data in the analysis. Actual weather data should be

collected from a source such as National Climatic Data Center (NCDC) weather station data.

The physical location of the weather station should be the closest available to the project site.

These data should be translated into weather data files that are compatible with DOE-2. In

the M&V plan, the Project Sponsor should specify which weather data sources will be used.

Typical weather data used in the calculation of energy savings should be either Typical

Meteorological Year (TMY) or TMY2 data types, obtained from the National Renewable

Energy Laboratory (NREL).

Building Simulation Models Once all necessary information is collected, the Project Sponsor inputs the data into DOE-2 code

to create the as-built model. The modeler should refine the model to obtain the best

Page 132: 2018 Commercial and Industrial Standard Offer Program MEASUREMENT AND VERIFICATION USING BILLING ANALYSIS AND REGRESSION MODELS.....82 OVERVIEW.....82

CenterPoint Energy SECTION III - 132 -

representation of the as-built building. Where possible, the modeler should use measured data

and real building information to verify or replace the program’s default values.

21.5.1 Calibration

After the as-built model is created and debugged, the modeler should make a comparison of the

energy flows and demand projected by the model to that of the utility data. All utility billing data

should be used in the analysis, electric as well as heating fuels, such as natural gas. The modeler

may use either monthly utility bills, or measured hourly data to calibrate the model when

available.

The modeler should document the calibration process to show the results from initial runs and

what changes were made to bring the model into calibration. Statistical indices are calculated

during the calibration process to determine the accuracy of the model. If the model is not

sufficiently calibrated, the modeler should revise the parameters of the model and recalculate the

statistics.

21.5.2 Hourly Data Calibration

In hourly calibration, two statistical indices are required to declare a model calibrated: monthly

mean bias error (MBE) and the coefficient of variation of the root mean squared error

(CV(RMSE))7. Equations below Error are used to calculate MBE and CV(RMSE).

MBE (%) =∑ (M − S)hrmonth

∑ Mhrmonth × 100

Where:

Mhr = the measured kWh for any hour during the month

Shr = the simulated kWh for any hour during the month

CVE (RMSEmonth) =√∑ (M − S)2

hr × Nhr month

∑ Mhrmonth × 100

Where:

Mhr = the measured kWh for any hour during the month

Shr = the simulated kWh for any hour during the month

Nhr = the number of hours in the month

The acceptable tolerances for these values when using hourly data calibration are shown in Table

38.

21.5.3 Monthly Data Calibration

Comparing simulated energy use to monthly utility bills is straightforward. First, the model is

developed and run using weather data that correspond to the monthly utility billing periods.

Next, monthly simulated energy consumption and monthly measured data are plotted against

each other for every month in the data set. Equations below are used to calculate the error in the

monthly and annual energy consumption, respectively.

Mmonth = the measured kWh for the month

Smonth = the simulated kWh for the month

ERRyear 15%

21.5.4 Baseline Models

After calibrated simulation of the as-built model, the baseline model can be prepared. The

baseline model is usually the as-built model with the substitution of minimum energy standards

for equipment and systems. This new baseline model should also be documented.

21.5.5 Minimum Energy Standards

The baseline model should comply with minimum state and federal energy standards with

respect to the following:

Baseline equipment/systems should not include devices (such as lamps and ballasts) that are

not allowed under current regulations.

Baseline equipment models should meet prescriptive efficiency standards for affected

equipment. These requirements are found local/federal energy codes. The applicable standard

requiring the highest efficiency should be used.

Baseline calculations do not have to comply with performance compliance methods that

require the project site to meet an energy budget.

21.5.6 Detailed Energy Savings Calculations

Energy savings are determined from the difference between the outputs of the baseline and as-

built models. Savings are determined with both models using the same conditions (weather,

occupancy schedules, etc.). To calculate savings, the energy consumption projected by the as-

built model is subtracted from energy consumption projected by the baseline model.

Program Manual v 18.1 G.M&V EXAMPLE

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION V. - 147 -

G. M&V EXAMPLE

G.1 Project Summary An owner of a 250,000 square foot office complex is participating in CenterPoint Energy’s C&I

Standard Offer Program. A central chilled water plant cools the facility with a 15-year-old 700-

ton centrifugal chiller. The owner of the building is planning to replace the older chiller with a

new, high efficiency unit. The new unit under consideration is rated with an ARI nominal COP

of 6.4 (0.55 kW/Ton). The baseline and minimum efficiency standards for water-cooled electric

chillers are taken from Appendix I, Table I.7 of the Standard Cooling Equipment Tables. For a

700-ton water-cooled chiller, the baseline efficiency is 4.7 COP, which is equivalent to 0.748

kW/ton. Likewise, for a 700-ton water-cooled chiller, the minimum efficiency is 6.1 COP, which

is equivalent to 0.577 kW/ton (and the unit qualifies for the program by having a higher

efficiency than the required minimum).

G.2 Assumptions This M&V plan is written with the following assumptions:

1. The office building is not planning any major projects that would significantly alter the

chiller load or schedule, such as building additions, significant changes in building

occupancy, or significant changes in building schedule.

2. The chiller operating schedule will not change because of this project.

Based on the assumptions and the fact that the new chiller is similar to the existing one (similar

size, water-cooled, no VFD, etc.), the only characteristic needed to estimate the demand and

energy savings is the full load efficiency of each chiller.

G.3 Project Activities The proposed method for conducting the M&V is from Section III, Chapter 6: Measurement

Guidelines for Replacement of Cooling Equipment. Since the simplified guidelines are being

used, pre-installation monitoring is not required. The project does require pre-installation and

post-installation inspections, post-installation monitoring of chiller demand (kW for at least one

hour at peak operating conditions), post-installation monitoring of chiller consumption (kWh for

the entire year), an Installation Report, and a Savings Report. The Project Sponsor shall be

responsible for all M&V activities and production of reports.

G.3.1 Inspections

CenterPoint Energy shall perform a pre-installation inspection to validate assumptions used in

the savings calculations, and verify the existing chiller efficiency. The best source of information

for the existing efficiency is the ARI certification, which accompanies the existing chiller. A

post-installation inspection will be performed to verify that the chiller was installed and is

operating as proposed in the approved Project Application.

G.3.2 Post-Installation Monitoring

Post-installation monitoring of chiller electrical consumption shall be conducted for the entire

M&V period. This monitoring will be accomplished using an ACME Inc., self-contained, three-

phase, true RMS kW logger. The logger collects time stamped data at 15-minute intervals. The

logger will be downloaded monthly and the data validated and stored. If there is a significant gap

in the data due to a logger failure, the process to replace the missing data with interpolated or

averaged data will be clearly documented. The 15-minute time stamped data will be used to

satisfy all post-installation monitoring requirements.

G.3.3 Reports

After the chiller is installed and commissioned, an Installation Report will be produced

documenting that the equipment specified in the PA was installed and is functioning as expected.

A Savings Report, following the guidelines and forms provided in the procedures manual, will be

generated and submitted upon completion of the data collection activities. Savings estimates will

be provided in spreadsheet form, following the template provided in Table G.2: Template for

Computing Savings, below. In addition to the reports, all monitoring data will be submitted in

electronic format for review by CenterPoint Energy.

G.4 Metering Plan The electrical demand of the proposed (new) chiller will be monitored to support the required

M&V activities. This three-phase load will be monitored using an ACME true RMS kW meter.

Current Transducers will be placed on Breakers 1, 3 and 5 of switch-gear SG-1. These breakers

are the A, B, and C phases of the 460 volt service that supplies the chiller. No other devices draw

power from these breakers.

The ACME meter will record electrical consumption at 15 Minute intervals for the duration of

the monitoring period. This logger is capable of storing 41 days of 15-minute data using a fifteen

minute interval. Data will be downloaded and stored on the first working day of each month to

ensure that the logger does not run out of memory.

G.5 Accuracy Requirements The ACME logger will be calibrated at the time of installation and then checked for calibration

every 6 months. This will be accomplished using a Powersite true RMS meter calibrated at the

factory to 2 percent of reading.

G.6 Data Gathering and Quality Control The data will be collected using quality control procedures for checking reasonableness. Any and

all missing intervals will be replaced either by interpolation or use of average values.

CenterPoint Energy will be notified of any data substitution because of missing data, and the

method employed to substitute the data.

G.7 Calculations and Adjustments The calculations described below will be performed for the Savings Report. The nominal

efficiencies of the chillers are provided again in Table G.1 below.

Program Manual v 18.1 H.TABLE OF STANDARD FIXTURE WATTAGES

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION V. - 151 -

H. TABLE OF STANDARD FIXTURE WATTAGES

H.1 Overview The Central Wattage Table contains reference data for estimating demand and energy savings in

the C&I Standard Offer Program for lighting measures. The Table assigns identification codes

and demand values (watts) to common fixture types (fluorescent, incandescent, HID, LED, etc.)

used in commercial applications. The Table wattage values for each fixture type are averages of

various manufacturers’ laboratory tests performed to ANSI test standards. By using standardized

demand values for each fixture type, the Table simplifies the accounting procedures for lighting

equipment retrofits.

CenterPoint Energy posts updated versions of the Table on the program Web site at

https://centerpoint.anbetrack.com/ as new fixtures are added. Project Sponsors should make sure

that they are working with the most recent version of the Table as they prepare Lighting

Equipment Survey forms.

If a project uses a fixture type not listed in the Table, the Sponsor should request that CenterPoint

Energy add a new fixture code. The request should include all information required to uniquely

identify the fixture type and to fix its demand. If possible, the request should be supported by

manufacturer’s ANSI test data.

The Lighting Equipment Survey Form is linked to a copy of the Central Wattage Table and looks

up wattage values for fixture codes automatically. For this reason, Sponsors should use only the

identification codes included in the Table.

H.2 Table The Table is subdivided into fixture types such as linear fluorescent, compact fluorescent,

mercury vapor, Light-emitting diode (LED) etc, with each subdivision sorted by fixture code.

Each record, or row, in the Table contains a fixture code, which serves as a unique identifier.

Each record also includes a description of the fixture, the number of lamps, the number of

ballasts if applicable, and the fixture wattage. A legend explains the rules behind the fixture

codes.

The US Energy Policy Act of 1992 (EPACT) sets energy efficiency standards that preclude

certain lamps and ballasts from being manufactured or imported into the US. Under the C&I

Standard Offer Program, all lighting equipment, including existing or baseline equipment, must

be EPACT compliant. As a result, certain lamp/ballast combinations, which are non-EPACT

compliant, are assigned EPACT demand values. Thus, a 4-foot fixture with 40-watt T-12 lamps

and standard magnetic ballast has the same demand value as a like fixture equipped with 34-watt

T-12 lamps and energy efficient magnetic ballast.

Program Manual v 18.1 I.STANDARD COOLING EQUIPMENT TABLES

2018 Commercial Standard Offer Program

CenterPoint Energy SECTION V. - 243 -

I. STANDARD COOLING EQUIPMENT TABLES

This document contains reference data for estimating demand and energy savings for cooling

equipment in the C&I Standard Offer Program. The data are equipment efficiency standards or

climate data that will be used to develop the baseline system models and to evaluate savings for

all projects under the C&I Standard Offer Program.

Cooling equipment installed under the program must exceed the minimum new equipment

efficiency standards shown in the tables. In addition, the minimum baseline efficiencies define

the baseline for calculating energy savings. The guidelines in Section III (M&V Guidelines),

Chapter 6 (Guidelines for Cooling Equipment) describe the application of these equipment

efficiency standards and coefficient tables for estimating baseline demand and energy use and

cooling equipment demand and energy savings.

For the following types of cooling equipment, baseline efficiency ratings are provided in

Appendix I below:

Unitary air conditioners and heat pumps (air cooled, evaporative cooled, or water cooled)

Packaged-terminal air conditioners and heat pumps

Room air conditioners and heat pumps

Water-source and ground-water source heat pumps

Water- and air-cooled water chilling packages

Appendix I presents the minimum efficiencies of particular types of cooling equipment. The

performance standard data in these tables should be used to determine the rated baseline

equipment efficiencies. The baseline for equipment for which rating conditions are not provided

shall be defined as the energy consumption of the actual existing equipment. Appendix I of this

document presents the cooling degree-days (CDD) for a weather station located in the

CenterPoint Energy distribution service territory. Cooling degree-day data are used to normalize

metered energy consumption to a typical meteorological year (TMY3). M&V Guideline 3

describes the application of weather data for estimating baseline energy use and cooling

equipment energy savings.

Table I.10 provides the coefficients necessary to complete the air-conditioning equipment

deemed savings calculation described in Section III, Chapter 6.

Table I.12 - Table I.15 present baselines for early retirement projects. Early retirement projects

must involve replacement of a working system. Baseline efficiency will be estimated according

to the capacity, type (package or split, heat pump or air conditioner), and year of manufacture of

the replaced system. Baseline efficiency levels for air conditioners and heat pumps are provided

in Table I.1, for systems installed between 1990 and 2007.

J. STANDARD MOTOR EFFICIENCIES TABLE

J.1 Overview

This document contains reference data for estimating demand and energy savings in C&I

Standard Offer Program for energy efficient motors and related measures. For motors installed

under the program, the equipment must exceed these minimum efficiency standards. In addition,

the minimum efficiencies define the baseline for calculating demand and energy savings. M&V

Guideline 7 for motor measures describes the application of these equipment efficiency standards

for estimating baseline demand and energy use and measure demand and energy savings.

J.2 Table The efficiencies of permanently wired, poly-phase motors that are at least one horsepower in size

and that are used for fan, pumping, and conveyance applications are defined in Appendix J is

based on ASHRAE Standard 90.1m-1995. Note, however, that the following motors are exempt

from these requirements:

Motors in appliances.

Refrigeration compressor motors.

Multi-speed motors.

Motors that are used as components of cooling equipment where the motors are part of the

efficiency ratings listed in the Appendix I Standard Cooling Equipment Tables.

The efficiency values given in Appendix J should be used to determine the equipment baseline.

Equipment installed under the C&I Standard Offer Program must be more efficient than the

standards shown to be eligible for incentives.

Program Manual v 18.1 M.M&V SAMPLE GUIDELINE

CenterPoint Energy SECTION V.1 - 271 -

M. M&V SAMPLE GUIDELINE

M.1 Overview This appendix provides guidelines for defining a sample of equipment for measurement and

verification purposes. In sampling, a large number of similar pieces of equipment affected by the

same energy-efficiency measure can be grouped into usage groups from which samples are

selected. These sampling guidelines are designed to provide assistance in determining the

number of sample points that should be monitored to meet the program precision requirements

and provide a reliable estimate of parameters such as annual energy savings or hours of

operation. If alternative approaches are proposed, they must be approved by CenterPoint Energy

and based on sound statistical principles.

M.2 Steps in Calculating Sample Size The number of pieces of equipment requiring monitoring can be calculated according to the

following steps:

M.2.1 Compile measure information

Compile the following information for the equipment affected by the measures. This step is

normally undertaken during the preparation of the Project Application.

Number of Fixtures/Equipment. Identify and document the fixtures/equipment that is

affected by the installation of measures in a survey that includes nameplate data, quantity of

equipment, and location information.

Projected Hours of Operation. Project the average hours of operation of the equipment. It

should be based on the experience of the building operator, on the operation of the affected

equipment or even some preliminary monitoring.

M.2.2 Designate usage group

Next, provide a brief description of the functional use of the space being audited. Functional uses

typically encountered in lighting for commercial and industrial facilities are provided in Table 29

of this manual. Usage groups for non-lighting measures are dependent on type of application.

Sources of information on operating characteristics, other than monitoring, used in defining

usage groups include: (a) operating schedules that provide information on energy consumption or

hours of operation; and (b) type of application or location that provides information on how and

when equipment (e.g., fixtures or motors) are operated. In some instances, area type alone may

be insufficient to designate usage groups. Usage groups may need to be further subdivided if an

area type is inherently variable in nature due to different characteristics of their occupants. For

example, some laboratories may have longer operating hours than others and should be divided

into different usage groups (e.g., computer laboratory lighting operates for 8 hours per day while

agriculture laboratories operate 4 hours per day).

M.2.3 Calculate sample sizes

Once the equipment has been divided into usage groups, the total sample size needed for these

groupings can be calculated. This approach produces a sample (with a coefficient of variation of

M.3 Over-sampling The initial sample size should be increased to compensate for potential reductions in the final

usable sample due to equipment failure or loss. Suggested guidelines are that the sample size be

increased by 10 percent.
