SECTION I. PREFACE
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.
SECTION II. PROGRAM GUIDELINES &
PARTICIPATION

offering deemed or simple savings calculations for many measures.
Diversify portfolio to include non-traditional measures which hardly or never appear in the
program.
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.

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.

2018 Commercial Standard Offer Program
CenterPoint Energy SECTION II - 12 -
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.
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.

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
Sent to the Attention of Loretta Battles
Addressed to: CenterPoint Energy, 1111 Louisiana 9th Floor, Houston, TX 77002

transferred to CenterPoint Energy emailed to [email protected]
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.
Program Manual v 18.1 PARTICIPATION PROCESS
2018 Commercial Standard Offer Program
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
Program Manual v 18.1 PARTICIPATION PROCESS
2018 Commercial Standard Offer Program
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.
Program Manual v 18.1 PARTICIPATION PROCESS
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION II - 29 -
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

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.

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.

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.

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.
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.
Table 13. Suggested Minimum Numbers of Usage Groups for Project Site Types
Building Type

Retail Stores 5 Sales floor, storeroom, displays, private office, 24-hr
Manufacturing 6 Manufacturing, warehouse, shipping, offices, shops, 24-
hr
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 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

* Sample sizes assume a confidence interval of 80%, precision of 20%, and a coefficient of variation (cv) of 0.5 for
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

Controls The addition of controls such as occupancy sensors and day lighting are measures eligible for the
program. Energy Savings resulting from reduced operating hours can be claimed with the
installation of controls. There are two paths that the Project Sponsor may take to claim savings
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
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.

Electric to Gas Equipment Replacements (Fuel switching)
Demand savings are allowed only for equipment that operates during the peak periods. Peak
demand savings are calculated according to Equations below.
𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 − 𝑘𝑊𝑛𝑒𝑤 𝑒𝑞𝑢𝑖𝑝
𝑘𝑊ℎ𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 − 𝑘𝑊𝑛𝑒𝑤 𝑒𝑞𝑢𝑖𝑝 − 𝐵𝑇𝑈𝑔𝑎𝑠 × (1

Where:
𝑘𝑊𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = maximum metered 15-minunte cooling equipment demand during the utility peak-
demand period, kW
𝑘𝑊𝑛𝑒𝑤 𝑒𝑞𝑢𝑖𝑝 = maximum demand of any new electric auxiliary equipment installed with the gas
engine chiller measured during the utility peak-demand period, kW
𝑘𝑊ℎ𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = summed metered cooling equipment energy use for one year, kWh
𝑘𝑊ℎ𝑚𝑒𝑡𝑒𝑟𝑒𝑑 = Annual energy usage of any new electric auxiliary equipment installed with the
gas engine chiller measured or predicted, kWh
𝐵𝑇𝑈𝑔𝑎𝑠 = Measured annual post-retrofit gas consumption
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:
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):

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

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.

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

𝑁ℎ𝑟 = the number of hours in the month

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.

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.
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)
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

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

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.

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

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
Program Manual v 18.1 Measurement Guidelines for Application of Window Films
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION III - 74 -
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.

The data from Table 22 are used to determine the demand and energy savings associated with the

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.

2018 Commercial Standard Offer Program
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
Program Manual v 18.1 Measurement and Verification for Generic Variable Loads
2018 Commercial Standard Offer Program
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.
Program Manual v 18.1 Measurement and Verification for Generic Variable Loads

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.

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

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
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

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.

2018 Commercial Standard Offer Program
CenterPoint Energy SECTION III - 82 -
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.

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.
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.

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?

CenterPoint Energy SECTION III - 86 -
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.
Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis
2018 Commercial Standard Offer Program
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
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,
Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis
2018 Commercial Standard Offer Program
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
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
23. Table 23.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
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.

Project-Specific M&V Issues Specific M&V issues that need to be addressed in the project-specific M&V plan and that are
related to this M&V method include:
Which version of DOE-2 will be used, the supplier of the program, and what if any pre- and
post-processors will be used?
Baseline building description (age square footage, location, etc.) including a description of
building systems to be replaced.

data).

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:

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”
Program Manual v 18.1 Measurement Guidelines for Lighting Efficiency and Controls

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:
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

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.

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
Minimum
Number of
Usage Groups
Examples of Usage Group types
Office Buildings 6 General offices, private offices, hallways, restrooms,
conference, lobbies, 24-hr
Education (K-12) 6 Classrooms, offices, hallways, restrooms, admin,
auditorium, gymnasium, 24-hr

rooms, labs, offices, hallways
Retail Stores 5 Sales floor, storeroom, displays, private office, 24-hr
Manufacturing 6 Manufacturing, warehouse, shipping, offices, shops,
24-hr
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
are multiple fixtures on a single circuit breaker (e.g., warehouse), then the Project Sponsor will
coordinate with CenterPoint Energy to determine number of samples required.

* Sample sizes assume a confidence interval of 80%, precision of 20%, and a coefficient of variation (cv) of 0.5 for the populations indicated
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
February 28.

accurately characterize the building type and operation, then the Project Sponsor must refer to
Metered Control Savings Method.

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.
Program Manual v 18.1 Measurement Guidelines for High-Efficiency Cooling Equipment
2018 Commercial Standard Offer Program
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.

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
1 Wolpert, J.S. and J. Stein, “Simulation, Monitoring, and the Design Assistance Professional,” 1992 International Energy and
Environment Conference.
Program Manual v 18.1 Measurement Guidelines for High-Efficiency Cooling Equipment
2018 Commercial Standard Offer Program
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
Program Manual v 18.1 Measurement Guidelines for High-Efficiency Cooling Equipment
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION III - 115 -
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

𝑁ℎ𝑟 = the number of hours in the month

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
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.

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
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
Program Manual v 18.1 Measurement and Verification for Generic Variable Loads
2018 Commercial Standard Offer Program
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.
Program Manual v 18.1 Measurement and Verification for Generic Variable Loads
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION III - 127 -
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
𝒌𝑾𝒃𝒂𝒔𝒆𝒍𝒊𝒏𝒆,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
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.
Program Manual v 18.1 Measurement and Verification for Generic Variable Loads
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION III - 128 -
𝑘𝑊𝑠𝑎𝑣𝑒𝑑 = 𝑘𝑊𝑏𝑎𝑠𝑒𝑙𝑖𝑛𝑒,𝑚𝑎𝑥 − 𝑘𝑊𝑝𝑜𝑠𝑡,𝑚𝑎𝑥

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
𝒌𝑾𝒃𝒂𝒔𝒆𝒍𝒊𝒏𝒆,𝒊= Baseline kW calculated from Baseline Model and corresponding to same time interval 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-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.

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,
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
Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis
2018 Commercial Standard Offer Program
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.

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,
Program Manual v 18.1 Measurement and Verification Using Calibrated Simulation Analysis

CenterPoint Energy SECTION III - 134 -
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.

Demand Savings: The maximum one-hour average demand reduction (in kW) that occurs when
the system undergoing retrofit is operating at peak conditions during the summer or winter
period. The summer period is defined as weekdays, between the hours of 1 PM and 7 PM from
June 1 until September 30, excluding holidays. 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, excluding
holidays.
Energy Efficiency Measure (EEM): A system, piece of equipment, or materials that result in
either reduced electric energy consumption, or reduced peak demand, or both.
Energy Efficiency Project: An energy efficiency measure or combination of measures installed
under a Standard Agreement that results in both a reduction in customers’ electric energy
consumption and peak demand, as well as a reduction in energy costs.
Energy Savings Estimates: Energy savings (in kWh) over 12 months derived from metering
and/or calculations in accordance with the provisions of the approved measurement and
verification plans, and documented in the Savings Report.
Project Application (PA): With the PA, CenterPoint Energy will collect a non-refundable
deposit equal to 5% of the incentive funding requested. Approval by CenterPoint Energy of the
PA signifies that funding has been reserved for the project. Project Sponsors must have detailed
the expected demand and energy savings and incentive payments for each project, to be included
in the Project Authorization, which is attached to the signed Standard Offer Program Purchase
Agreement between CenterPoint Energy and the Project Sponsor.
Full Measurement and Verification: A detailed estimate of savings using a higher level of
rigor than in the deemed savings or simple M&B approaches through the application of
metering, billing analysis, or computer simulation.
Installation Payment: The first of two incentive payments made to a Project Sponsor. The
installation payment is 40% of the total estimated incentive amount.
Installation Report (IR): After approval of the PA and issuance of a Project Authorization, a
Project Sponsor may proceed to install the energy efficiency measures included in an application.
After installation is complete, the Project Sponsor will submit an Installation Report giving
details about the equipment installed at each customer site. Once CenterPoint Energy receives
the IR, CenterPoint Energy or its M&V designee will inspect the customer sites to ensure
installation and operation of the equipment.

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-
Program Manual v 18.1 G.M&V EXAMPLE
2018 Commercial Standard Offer Program
CenterPoint Energy SECTION V. - 148 -
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.

The illustrative load data represents chiller consumption in the month of June. Energy savings
(kWh) will be estimated in each month by multiplying the average hourly kWh with the number
of days in the month. The energy savings for each month will then be aggregated into an annual
savings estimate. The peak data shall be used to estimate the peak demand savings (kW).
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.

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.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.

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

0.5) expected to estimate the average hours of operation with sufficient accuracy. The following
table shows the number of samples required in a usage group.

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.
