1. EXECUTIVE SUMMARY

The savings estimation technical reference manual describes – for program administrators,

regulatory agencies, program evaluators, utility customers, and other interested stakeholders –

how California publicly owned utilities1 consistently, reliably, and transparently calculate

energy savings for their energy efficiency programs.

The reference manual provides the methods, formulas, and default assumptions used for

estimating energy savings and peak demand impacts from energy efficiency measures and

projects. The energy savings estimates are used to report program accomplishments and

measure progress towards program goals.

Energy efficiency measures are documented and classified as either unit energy savings

measures, provisional measures, semi-custom measures, or custom measures. The manual

presents both nonresidential and residential measures. Each measure type is presented in

separate sections and grouped by technology type. Measure information is presented in a

consistent tabular format.

The reference manual also includes spreadsheets that provide detailed and transparent measure

calculations and, for certain semi-custom measures, energy savings calculators for estimating

energy savings for project-specific measures. The measure spreadsheet includes summary tables

for transferring measure savings data into the program’s regulatory compliance reporting tool.

The current 2016 version of the manual includes updates to account for code changes since the

2014 version was published. It also includes several new measures and updates to existing

measures. Provisional measures are included for the first time in Section 17. TRM spreadsheets

were added or revised as needed. In addition, new TRM spreadsheets are added that simplify

the use of the lighting and VFD calculators.

2. INTRODUCTION

The savings estimation technical reference manual describes – for program administrators,

regulatory agencies, program evaluators, utility customers, and other interested stakeholders –

how publicly owned utilities consistently, reliably, and transparently calculate energy savings

for their energy efficiency programs.

2.1 Purpose

The reference manual provides the methods, formulas, and default assumptions used for

estimating energy savings and peak demand impacts from energy efficiency measures and

projects. The energy savings estimates are used to report program accomplishments and

measure progress towards program goals.

2.2 Background

California publicly owned utilities annually report their program accomplishments to the

California Energy Commission. As mandated by California state law (SB1037, AB2021, Section

9505 of the Public Utilities Code), each utility reports its program energy savings on an annual

basis. Since 2006, California publicly owned utilities have collaborated to develop tools and

resources for consistently and reliably reporting program energy savings.

The first source of energy savings estimates used to report program savings was published in

2006 and subsequently updated in 2008 and 2009. In 2014, the previous versions of the manual

were superseded by a new version of the manual.

2.2.1 What’s New in 2016

The current 2016 version of the manual includes updates to account for code changes since the

2014 version was published. It also includes several new measures and updates to existing

measures. Provisional measures are included for the first time in Section 17. TRM spreadsheets

were added or revised as needed. In addition, new TRM spreadsheets are added that simplify

the use of the lighting and VFD calculators.

2.3 Approach

The reference manual documents and classifies energy efficiency measures in three ways: unit

energy savings (UES) measures, provisional measures, semi-custom measures, and custom

measures.

Section 2 Introduction

2-2 Savings Estimation TRM

ers

UES measures, previously defined as deemed savings measures, are normalized savings

estimates that represent the most typical savings expected from a range of similar measures.

These savings estimates are used for reporting savings at the program or at a regional level.

The UES measures provided in this manual are based on credible and reliable sources of

energy savings estimates and savings estimate parameters, generally those that have been

documented and vetted through either peer engineering review or a regulatory process

governing efficiency programs. As such, the UES savings estimates are based on the most

current and best available resources.

Semi-custom measures are measures for which the savings estimates can vary significantly

depending on how or where the measure is used. Savings estimates are calculated using

standard methodologies based on project-specific parameters. For semi-custom measures, the

manual documents the savings methodology and may also provide a standardized savings

calculator for use in estimating energy savings.

Custom measures are project-specific actions, equipment changes, or system improvements

that reduce energy consumption. This manual outlines a protocol for program administrators

to use that will consistently and reliably estimate and document energy savings estimates for

custom measures.

Provisional unit energy savings measures are measures that do not yet meet the reliability

standard of a UES measure. The most typical are emerging technology or newly-adopted

program measures that exhibit significant energy saving potential. Provisional savings

estimates provide an interim solution for reporting measure savings while testing, evaluation,

or demonstration efforts are under way to validate energy savings estimates.

2.4 Manual Organization

The reference manual consists of both this document and its supporting spreadsheets.

The manual presents both nonresidential and residential measures. Each measure type is

presented in separate sections and grouped by technology type. Measure information is

presented in a consistent tabular format consisting of the following sections:

Measure summary information – Provides a brief description of the measure, its

applicability, savings type (UES, semi-custom), energy savings, incremental measure cost,

and effective useful life (EUL)

Baseline and efficient case conditions – Defines the baseline type (see Section 3 –

Definitions) and provides a brief description of the baseline and efficient case conditions.

Savings calculation – Documents the savings methodology and algorithms used to

estimate savings

Key parameters – Lists key operating parameters that have the most influence on energy

savings estimates

Introduction Section 2


ers

Quality assurance, design, installation, commissioning, and operation – Provides key

quality assurance checks to help ensure that the estimated savings are realized

Important notes – Provide further explanation, clarifications, or relevant supporting

information

All references and data resources are identified in the table footnotes.

As needed, each section also contains supplementary tables and charts to provide additional

measure details. Measures with multiple savings values (savings by size, building use, varying

levels of efficiency, etc.) will have savings and cost data listed in a supplementary table. If the

number of measures is too large to include in a supplementary table, they are listed in the

supporting spreadsheet summary table. The spreadsheet summary table allows measures to be

filtered by climate zone and, if applicable, by building type.

The last section of the manual provides the custom measure protocol, which outlines a process

for estimating and documenting custom measure savings.

The reference manual spreadsheets provide the detailed measure calculations. For UES

measures, the spreadsheet consists of a summary table, a calculation narrative, measure savings

calculations, and reference data. The summary table is constructed to provide easy transfer of

measure data into the program’s regulatory compliance reporting tool.

Energy savings calculators are also provided as part of the reference manual. The calculators

are Excel spreadsheet-based engineering models for estimating semi-custom measures per the

described methodology. They provide a simple and transparent approach for estimating

project-specific energy savings.

2.5 Manual Update Process

In order to maintain the most current and best available estimates of energy savings, the

reference manual should be reviewed and updated on a regular basis. Measures should be

reviewed to determine if newly adopted code changes will affect the energy savings estimates.

Measure savings estimates may need to be updated based on new sources of information, such

as market research studies, technology studies, or program impact evaluation reports. In

addition, assumptions used in the measure baseline definitions may over time become obsolete

or otherwise no longer applicable.

Manual review and updates to incorporate code changes should occur on an annual basis, or at

the time when code updates go into effect. Updates for measures which represent a significant

amount of program energy savings should occur on an annual basis. Manual updates to

incorporate the most current and best available information for all measures should occur every

2 to 3 years.

2.6 Applicable State and Federal Codes

Within each measure description, the measure savings estimate baseline is described. Where the

appropriate baseline is determined to be code, the applicable state or federal code is identified.

The codes used in determining savings estimate baselines include:

California 2012 and 2015 Appliance Efficiency Regulations (California Code of

Regulations, Title 20, sections 1601‒1608)

California 2013 and 2016 Building Energy Efficiency Standards for Residential and

Nonresidential Buildings (California Code of Regulations, Title 24, part 6 and associated

administrative regulations, part 1)

Department of Energy Code of Federal Regulations, Title 10

Definitions 3

3. DEFINITIONS

In this manual, the following definitions apply:

custom measure – Any measure not defined by this manual as either a unit energy savings

measure or a semi-custom measure. In more general terms, a custom measure is defined as an

energy-related project, action, equipment change, or system improvement that reduces energy

consumption.

effective useful life (EUL) – An estimate of the median number of years (from a statistically

representative sample) that an installed measure is expected to be operable and capable of

performing its intended function. The primary source of EUL is the California Public Utilities

Commission’s Database for Energy Efficient Resources (DEER).

efficient case – Describes the affected equipment or system condition after an energy efficiency

measure has been implemented or installed. Also referred to as the post-retrofit condition.

energy use baseline – Energy use that is compared to the efficient case energy use for the

purposes of estimating future annual energy savings. The baseline is identified as being one of

the four following types:

natural replacement – code – Describes an energy use baseline that is based on current

minimum energy efficiency code requirements as established by the applicable local,

state, or federal jurisdiction.

natural replacement – current practice – Describes an energy use baseline that is based

on standard industry practice or market availability.

natural replacement – preexisting conditions – Describes the projected energy use

baseline that is based on the energy performance of the existing systems or

equipment that was in place before a measure was implemented. This baseline is

applicable if retaining the preexisting conditions over the entire effective useful life

of the measure is a realistic option.

dual baseline – early retirement – Describes the use of two energy use baselines to

determine energy savings where equipment with remaining useful life (RUL) is

replaced. In general, the first baseline is based on preexisting conditions and the

second baseline is one of the three types of natural replacement. See Section 16.1 for

a description of how a dual baseline is used in estimating measure cost-effectiveness.

measure cost – The incremental cost of implementing the energy savings measure. For

measures with an adjusted baseline, it is the incremental cost of the more-efficient measure

Section 3 Definitions


ers

compared to the cost of a code-compliant or current practice measure. For a preexisting

baseline, it is the full implementation cost of the measure. Installation costs not directly

associated with the energy savings measure are not included.

peak demand – The California grid-level average hourly peak demand occurring during a 3-

hour time period (2:00 p.m. – 5:00 p.m.) on a summer weekday from June to September. It also

can be defined for weather-sensitive measures as the maximum hourly peak demand occurring

between 2:00 p.m. and 5:00 p.m. during 3 consecutive weekdays containing the weekday with

the hottest temperature of the year.

semi-custom measure – An energy savings measure for which the savings estimates varies

significantly depending on how or where the measure is used (project-specific parameters).

Semi-custom measure savings are calculated using standard methodologies or standardized

saving estimate models (e.g., spreadsheet models).

UES measure – A unit energy savings measure that has unitized savings estimates (e.g., savings

per motor, savings per hp) that represent an average or weighted average of similar savings

measures. UES measures were previously known as deemed savings measures.

The UES measures provided in this manual are based on credible and reliable sources of

energy savings estimates and savings estimate parameters, generally those that have been

documented and vetted through either peer engineering review or a regulatory process

governing efficiency programs.

Provisional measure – A measure that does not meet the reliability standard of a UES

measure. The most typical are emerging technology or newly adopted program measures that

exhibit significant energy saving potential. Provisional savings estimates provide an interim

solution for reporting measure savings while testing, evaluation, or demonstration efforts are

under way to validate energy savings estimates.

4. COMMON DEFAULT FACTORS

This section provides the default values used in estimating energy savings for UES and semi-

custom lighting measures. Three default values are used: HVAC interactive effect, operating

hours, and peak demand factors.

Energy efficient lighting measures reduce the internal heat gain of air-conditioned spaces. This

reduction in heat gain reduces the cooling energy consumption and increases heating energy

consumption. Default interactive effect factors have been developed as part of the DEER

resources2 to account for these interactions in typical building end-use types. These default

interactive effects are used in the savings estimates for UES and semi-custom measures

provided in this manual.

Tables 4-1 through 4-4 provide the air-conditioning cooling interactive effect factors (HVAC IE

factors) used for lighting measures.

End use HVAC

Project eligibility 1. For retrofits, the units meet the regulatory definition of replacement units: non-standard sized units (less than 16 inches high or less than 42 inches wide with a cross-section area less than 670 square inches) specially manufactured for replacement applications. The units are designed to fit into the sleeve of the replaced unit.

2. For new construction, the units exceed the new construction (standard size) code efficiency requirements ‒ see the Unit Efficiency Ratings Table.

3. New construction measures are limited to units with a capacity of less than 7,000 Btu/h.

Savings type UES

Unit energy savings 1. Measure savings are found in the TRM101 spreadsheet.

2. With twelve climate zones, sixteen unit types, and two building types, savings for 384 measures are provided.

3. Each replacement unit measure has both natural replacement-code and dual baseline-early retirement savings values.

4. All savings are listed per ton of cooling.

Incremental measure cost 1. $144 per ton for replacement units1

2. $34 per ton for new construction unit costs2

EUL 15 years3


Applicable baseline types 1. Natural replacement – code

Baseline description 1. For retrofit units, the baseline efficiencies are based on non-standard, replacement

units as defined in Federal Code of Regulations2. The federal code requirements can

also be found in the 2013/2016 Title 24 code requirements.

2. For new construction units, the baseline efficiencies are based on standard units as defined in the Federal Code of Regulations..

Efficient case description 1. For retrofit units, the minimum unit efficiency rating meets the requirements listed in the Unit Efficiency Ratings Table.

Important Notes

Due to the recent federal code changes, there are currently (as of March 2013) no ENERGY STAR-qualified PTAC or PTHP units.

Most new construction units available (per AHRI directory) do not exceed code efficiency requirements by enough to provide sufficient savings to be a cost-effective measure. Therefore, the only size category included in the new construction savings estimates is for PTHP and PTAC units with a capacity of less than 7,000 Btu/h.

Based on a 2011 market survey conducted by U.S. EPA4, there are a limited number of replacement units available at the

efficiency ranges assumed by DEER (nearly 20% greater than code).

The efficiency rating for PTAC retrofit units in the 7,000 to 15,000 Btu/h size range is based on a

unit size of 11,000 Btu/h. To determine the efficiency rating for all unit sizes within this range

that provide the same level of energy savings, the following formula is used: EER = 13 - (0.25 ×

Cap/1000), where Cap is the unit-rated cooling capacity in Btu/h. For PTHP retrofit units, the

formula is: EER = 13 - (0.255 × Cap/1000).

Project eligibility Covers measures not specified as a UES lighting measure; however, UES measures with project-specific parameters are eligible under this measure

Savings type Semi-custom

Unit energy savings Project-specific savings are calculated using the energy savings calculators. The calculators can also be used to develop program-specific unit energy savings estimates for common lighting measure retrofits

Measure cost Project-specific costs are used to determine cost-effectiveness

EUL Rated lamp life divided by default annual operating hours for each building type 1.

Applicable baseline types 1. Natural replacement – preexisting conditions

2. Natural replacement – code

Baseline description Either the code minimum lighting power density requirement or preexisting light fixture power

Efficient case description Retrofitted fixtures, replacement fixtures, newly installed fixtures, or newly installed lighting controls

Savings Calculation

Annual energy savings Savings can be estimated using one of the lighting savings calculators, which are Excel 2010 spreadsheet models for estimating energy savings.

The TRM400 energy savings calculator for nonresidential lighting is intended for use by utility program administrators and covers all lighting measure types. Savings calculation formulas and methodologies are fully documented in the calculator.

The TRM404 spreadsheet provides a simplified lighting rebate calculator. It provides an easy-to-use interface for the lighting calculator. It includes a program administrator section where incentive rates, climate zones, and estimated code impacts can be set or adjusted. If a code baseline is applicable, the saving estimates are adjusted by a predetermined factor.

Peak demand reduction Default CDF factors are used to estimate peak demand reduction.

Section 6 Lighting Measures – Nonresidential


ers

Key Parameters

The TRM savings calculators allows the use of either default operating hours by building type or manual input of operating hours based on building operator interviews or field-measured data.

Lighting control savings factors are primarily based on studies2 with measured field data. However, given the 1.

large variability in control savings, project-specific measured data may be preferred over the default values. In addition, Title 24 requires controls for many end-use space types. Where applicable, the TRM400 lighting calculator includes code-required controls in the measure baseline.

Space end-use types are used to determine default operating hours. 2.

Where code baseline requirements will be applied, the TRM400 calculator uses space end-use types to 3.determine the lighting power allowance used in determining the space baseline lighting power.


Confirm that the existing fixture quantity, fixture type, location/end-use type, and control type are correctly 1.entered into the calculator.

The retrofit and replacement fixture type selected in the calculator should be verified as an appropriate 2.replacement for the existing fixture.

Lighting operating hours should be verified through operator interviews or field measurement. 3.

New lighting controls installed should be verified to be applicable to the space where they are applied. 4.

New lighting controls installed should be commissioned to ensure they are properly functioning. 5.

Important Notes

March 2016: The lighting calculators include revised lighting power allowances from the 2016 Title 24 code that goes into effect on January 1, 2017. For 2016 Title 24 lighting alterations, the calculator code application tables will no longer be needed. The CEC will be creating lighting alteration compliance documentation that can be used by the program administrator to determine code applicability and lighting power allowances.

After July 1, 2014, Title 24 code requires occupancy sensor controls for several space end-use

types. Where applicable, the occupancy control savings factor is included in the baseline energy

use calculation.

Daylight controls may also be applicable to a space if the lighting power exceeds a certain

threshold. However, actual application of daylight controls is determined through space

daylight zone analysis. If this analysis indicates that fixture daylight control is required, the

daylight sensor savings factor should be applied to the preexisting (baseline) conditions.

Savings Calculation

Annual energy savings Savings are project-specific and can be estimated using the TRM401 pump and 1.fan VFD calculator, an Excel 2010 spreadsheet model for estimating energy savings. TRM405 is a simplified fan rebate calculator. TRM 406 is a parking garage fan VSD rebate calculator. TRM407 is a pump VSD rebate calculator.

Fan and pump performance curves used to estimate savings are generic curves 2.

developed by BPA2

and are based on manufacturer performance data.

The VFD calculator allows for either standard load profiles or custom load 3.profiles developed by the user based on actual operating conditions.

Peak demand reduction In general, there is no peak demand reduction for this measure. It is possible, depending upon operating conditions, that there is a 2%–5% demand penalty due to the efficiency losses associated with the addition of a VFD controller operating at 100% flow.

Key Parameters

Performance curves and load profiles

For improved accuracy, generic performance curves can be replaced with performance curves developed using actual manufacturer data. Load profile accuracy can be improved by trending post-installation fan performance.


Determine design and control mechanism for preexisting fan or pump system. 1.

Determine if load being served is constant or variable. 2.

Determine if the application of VFD control is appropriate (e.g., no high static head or operational performance 3.issues).

Ensure that the VFD is installed correctly and that pump or fan speed is controlled appropriately. 4.

Important Notes

Installation of VFDs is considered industry standard practice for a majority of applications and is required by 1.code for a variety of HVAC applications. Savings are applicable only if a VFD would not have been installed otherwise.

Using measured trend data to estimate and validate energy saving is the most accurate method for estimating 2.energy savings for fan and pump VFD retrofits. When measured data is unavailable, the VFD calculator will provide a reasonable estimate of potential energy savings given the project meets the eligibility criteria previously stated.

The calculator includes a default load profile for a garage fan being controlled by a CO2 sensor, based on 3.measured field data.

Baseline description Title 20 compliant clothes washer, MEF = 1.26.

Efficient case description CEE Tier 3-qualified clothes washer

Savings Calculation


IOU work paper1

Energy savings are achieved by a reduction in heated water use and a reduction in dryer energy use (efficient water spin cycles remove more water from clothes).

Savings values are based on various assumptions regarding clothes washer market shares, weighted average efficiencies of standard and efficient washers, and RASS-based populations of gas and electric dryers and hot water heaters.

Peak demand reduction The residential energy/peak factor of 0.417 from DEER 2005 was used to calculate the peak demand.

Savings Calculation


The energy savings were determined using the ENERGY STAR savings calculator. 1.

Calculator assumes demand wattages for low, medium, and high fan speeds for 2.standard and efficient units. It also gives lighting wattages for standard and efficient units.

ENERGY STAR assumes average daily operating hours for the fan and lighting in 3.different regions of the country and gives a percentage of time at each speed setting. The Pacific region was used to determine operating hours.

Peak demand reduction The demand savings were calculated by multiplying the demand savings at each fan speed by a weighting factor that corresponds to the percentage of the total operating hours the fan spends at that speed. These three numbers were summed and then added to the demand savings of the lighting to determine the total demand savings of 0.123 kW.

Key Parameters

N/A


Verify that fan is ENERGY STAR qualified.

Unit energy savings for a new ENERGY STAR refrigerator/freezer are not included in the measure savings.

3/15/2016: Recent updates to DEER for 2016 indicate that the savings potential for recycling programs has been reduced by close to half of previous savings estimates. It is not fully documented as to why the savings have been reduced, but it is most likely associated with relatively newer, more efficient units being recycled. Program administrators should use the updated DEER savings estimates (included with TRM spreadsheet documentation) for reporting savings after 1/1/2017.

Savings Calculation

Annual energy savings

Savings were derived from the National Renewable Energy Laboratory (NREL) study

and analysis on hot water heat pumps (HWHPs).3 Energy modeling software

(TRNSYS) was used to estimate savings for a prototypical home. For HWHP installed in the conditioned space of the home, the additional heating load for home’s HVAC system is included in the savings results. NREL’s analysis concluded that a HWHP’s overall operating performance is less efficient than indicated by standard test procedures used to develop unit energy factor (EF) ratings.

Peak demand reduction NA – based on typical energy use profiles, a DHW heater does not contribute to peak demand

Key Parameters

ers


1. Verify that the unit is ENERGY STAR qualified.

2. If HPWP has an exhaust duct, verify that the duct is adequately sized.

Important Notes

1. HPWHs use the surrounding air as a heat source. If the HWHP is installed within the home, it imposes a heating load on the home’s air conditioning system.

2. Unit efficiency decreases as the ambient temperature falls below 68°F. If ambient space temperature falls below 45°F, the unit’s electrical resistance heaters are enabled, significantly lowering the heater’s energy performance.

5. Heat exchanger load factor reduces stream trap losses.

6. The combined load factor/pressure factor is 21.4%.

The TRM402 steam trap savings calculator can be used to determine more accurate, project-specific savings estimates. The calculator is designed to estimate savings for both replacement and repair of steam straps. Calculations are based on site steam system characteristics and steam trap size and type.

Custom Measure Protocol 16


ers

16. CUSTOM MEASURE PROTOCOL

This section describes how program administrators can reliably estimate and document energy

savings for custom measures.

A custom measure is any measure not defined by this manual as either a unit energy savings

measure or a semi-custom measure. In more general terms, a custom measure is defined as an

energy-related project, action, equipment change, or system improvements that reduce energy

consumption.

16.1 Baseline Use in Estimating Energy Savings

In order to estimate energy savings, energy usage must be determined for both a baseline and

an efficient-case condition. The baseline condition is an estimate of the future energy use that

would have occurred in the absence of the installed measure. It is constrained by the available

alternatives to installing the measure. Alternatives are often project-specific and may include

“do nothing” or be limited by minimum code requirements or product availability. In practice,

the pre-retrofit energy use is adjusted3 to account for the alternative constraints and normalized

for comparison to the efficient-case condition. The efficient-case condition is the energy

consumption after the measure has been implemented. Energy savings are the difference

between the baseline and efficient-case energy use.

3 Often referred to as the adjusted baseline. In the context presented in this manual, adjusted baseline and

baseline have the same meaning.

Section 16 Custom Measure Protocol


ers

Figure 16-1 Baseline and Efficient Case Energy Use

16.1.1 Baseline Examples

The following are examples of how pre-retrofit conditions are adjusted to determine the

baseline energy use:

Energy code baseline adjustment – The lighting fixtures in a warehouse are to be completely

replaced with new energy efficient high-bay fixtures. Energy code requires fixture replacements

to meet current code lighting power densities. Therefore, the baseline energy use is based on the

existing fixtures or on the energy code requirements, whichever uses less energy.

Federal regulations baseline adjustment – Lighting fixtures with T12 lamps will be retrofitted

with high performance T8 lamps and new ballasts. Recent federal regulations have ceased the

manufacturing of standard T12 lamps, such as the ones in the fixtures to be retrofitted. If the

existing stock of T12 replacement lamps has been depleted, then T12 lamps are not a viable

option. Therefore, the baseline energy use is based on a fixture lamp that meets federal

regulations. The lamp choices would be either first-generation T8 lamps or code-compliant T12

lamps (high-efficacy T12 lamps made with rare-earth elements that meet federal regulations).

Production rate baseline adjustment – An electric boiler at a manufacturing plant will be

replaced with a new, energy efficient boiler with heat recovery. The existing boiler energy use is

driven by the amount of product produced at the plant, which varies based on market demand.

The baseline energy use is based on the existing boiler energy use per unit of product produced,

which allows the projected baseline energy use to be compared to the efficient-case energy use.

Current practice baseline adjustment – A plant is expanding and needs to replace a heat

exchanger to meet its new capacity requirements. The existing two-stage heat exchanger is

considered obsolete. The least-efficient heat exchanger available for purchase is a four-stage

Custom Measure Protocol Section 16


ers

heat exchanger. Therefore, the baseline energy use is based on the use of a four-stage heat

exchanger to meet the expanded capacity requirements.

16.1.2 Dual Baseline

A dual baseline is used to properly assess a measure’s cost-effectiveness when more than one

baseline is applicable over the life of the measure. In this scenario, the baseline energy use for

the first baseline time period may be the preexisting conditions and is limited to the remaining

useful life (RUL) of the preexisting equipment. The second baseline energy use is based on code

or current practice, and its time period starts after the RUL time period ends and continues up

to the effective useful life (EUL) of the measure. The energy savings benefit of the measure

(used in cost-effectiveness tests) is based on the sum of the annual savings over the life of the

measure. Note that annual energy savings in this context is not the same as first-year savings,

which may be used for tracking program energy savings goals.

For example, consider that a packaged AC unit is replaced with a more energy-efficient unit.

The existing AC unit is 8 years old at the time of replacement, and its EUL is 15 years. The first

baseline energy use is based on the existing AC unit’s efficiency and the calculated annual

energy savings for this baseline is appropriate for the first 7 years (EUL minus the age of the

unit) of lifecycle energy savings. The second baseline energy use is based on the current energy

code efficiency requirements, and the calculated energy savings for the second baseline is

appropriate for the last 8 years of life cycle energy savings.

Figure 16-2 Dual Baseline Example

16.2 Energy Savings Estimate Approach

Custom measure energy savings can be estimated by using one of the three following

approaches:

1. Modified unit energy savings – The program administrator uses the analysis methodology

provided for a UES (or semi-custom) measure and adjusts project-specific parameters that



ers

differ from those specified for the measure. This is often the simplest approach, because the

savings estimate methodology, assumptions, and key operating parameters are already

documented. Only the project-specific changes need to be documented.

2. Unit energy savings from other credible sources – Credible sources of reliable savings

estimate are those documented and vetted through peer engineering review or regulatory

process. Examples of credible sources include: California DEER database, CPUC-

approved IOU work papers4, Regional Technical Forum (RTF) approved and provisional

savings estimates and protocols, Efficiency Maine Technical Reference Manual, and the

New York Department of Public Service Technical Reference Manual. Use of savings

values from other credible sources should be confirmed to be current and the best-

available source of savings estimation. The underlying assumptions, conditions, or other

factors on which the savings estimates are based on should be verified as applicable for its

intended use. Note that weather-sensitive measures from other regions may need to be

adjusted for local climatic conditions.

3. Project-specific savings calculations – The program administrator estimates energy

savings using generally accepted engineering calculations and methodologies. Or, the

program administrator sets guidelines for program participants to provide energy savings

estimates. In either case, the energy savings estimates should be consistent with the

approach described in this section of the manual and fully documented.

16.3 Measure Description

The custom measure description should be described in terms of what systems or equipment is

affected, how the measure will be implemented, and how energy will be saved. Key

assumptions or operating parameters should also be described. The description is summary in

nature, and it is written so it clearly conveys all key aspects of the measure. The level of detail is

contingent upon the measure’s complexity or its uniqueness.

What systems or equipment are affected – Identify the system or equipment that will

reduce its energy consumption after the measure is implemented. For example, the

building’s central cooling plant utilizes two 25 hp chilled water supply pumps to deliver a

constant flow of chilled water to multiple air handlers. Another example: The open office

area is illuminated by recessed 4-foot, four-lamp T12 lighting fixtures. The lights are

controlled by time clocks.

How the measure will be implemented – Describe what actions are taken, what

equipment is removed or installed, or what changes are made to the affected system. For

the previous two examples: VFDs will be installed to control the speed of the two chilled

water pumps, the air handlers’ three-way valves will be replaced by two-way valves, and

new control algorithms will be programmed into the existing building automation system

4 Note that older versions (pre-2012) of IOU work papers or DEER data (pre-2011) may be obsolete and

not representative of the best available energy savings information.



ers

to vary chilled water flow based on zone cooling load. Or, for the lighting system

example, the existing fixture T12 lamps and ballasts will be retrofitted with high

performance T8 lamps and premium electronic ballasts. Two T8 lamps will replace four

T12 lamps in each fixture. Occupancy sensors will be installed in the private offices.

How the measure saves energy – Explain how implementing the measure brings about a

reduction in energy use. For the HVAC example: By converting the chilled water flow

from constant to variable flow, the chiller water pump speed will vary and therefore use

less energy. For the lighting example: The new lamps and ballast require less power while

maintaining space lighting levels. The private office occupancy sensors will reduce the

lighting on-time by turning off lights when the office is unoccupied.

Key assumptions and operating parameters – Identify the key assumptions or operating

parameters that significantly affect the estimated energy savings. Often, these parameters

are the focus of post-project evaluation efforts to verify reported energy savings. For the

HVAC example: System trend data indicates the cooling system operates most of the time

at part load, with the majority of operating hours at or near 50% of full load. For the

lighting example: The building is occupied for more than 16 hours per day, resulting in

more than 3,000 annual lighting operating hours. Although the private office lights have

manual switches, building staff reported that the lights are never turned off. Occupancy

light loggers were deployed and they confirmed that the lights are operating for extended

periods when the offices are unoccupied.

Examples of operating parameters – Examples include: hours of operation, occupancy

schedules, production rates, variable or constant loads, automated control sequences (i.e.,

the boilers are shut off when the outside temperature is above 60°F), conditioned or

unconditioned space, human interaction and behavioral influences, interactive effects, and

equipment efficiency at full and part load.

16.4 Savings Calculation Methods

To estimate energy savings, the baseline and efficient case energy use are estimated. The

difference between the two is the measure energy savings. Annual energy savings are estimated

using an engineering model or estimated/validated through measurement and verification.

16.4.1 Engineering Model

Engineering models are generally one of two types: a spreadsheet model or a computer

software model. The engineering model can be as simple a single equation utilizing applicable

input parameters (i.e., difference in pre- and post-equipment efficiency multiplied by equivalent

full load hours) or a more complex analysis that accounts for dynamic operating parameters

and system interactions that affect energy use. A spreadsheet HVAC bin analysis, for example,

can be constructed to account for variable cooling and heating equipment loads that correlate to

outside weather conditions, production schedules, occupancy schedules, and/or operating

schedules. Computer software simulation models are effective at modeling complex and

dynamic building, equipment, or system interactions that affect energy use.



ers

16.4.2 Model Transparency

Engineering models are subject to review. For models submitted by the program participant,

the program administrator must be able to review the savings estimates to ensure its validity.

Models used by a program administrator to estimate program or project-specific measure

savings are often subject to third-party review for the purposes of validating energy savings.

To assure an engineering model’s savings estimate is valid and reliable, the model should be

transparent and accessible to the reviewer. The savings algorithms for all calculations should be

completely described and sufficient enough so that the reviewer can reproduce the saving

estimate results. Equations in spreadsheet cells should be summarized (for each applicable

group or category) and each equation constant or variable defined. Any values derived from

external references or sources should be described. For complex models, a narrative should

accompany the model to guide the reviewer through the analysis.

Spreadsheet mega-formulas should be sufficiently described so that any reviewer can follow

and confirm the formula logic. A mega-formula is a complex formula created by combining

multiple formulas into a single formula, and it is characterized by the use of multiple embedded

functions. Mega-formulas are very difficult, if not impossible, to decipher, so it is essential that a

step-by-step breakdown of the formula be fully explained.

16.4.3 Measurement and Verification

Where savings estimates are highly variable or uncertain, post-project M&V can be used to

either validate energy savings or be the source of reported energy savings. Measurement and

verification (M&V), as defined by the IPMVP5, is the process of using measurements to reliably

determine actual savings. There are a variety of methods defined by IPMVP for using measured

data to estimate savings. They generally involve using measured data as input for engineering

models (the measured data calibrates the engineering model to site-specific conditions) or as the

basis of statistical models, such as a whole-building utility bill analysis. Statistical models can be

used to estimate energy savings based on measured data that is correlated to key parameters

that affect energy use, such as weather or production. In addition to the IPMVP, there are a

variety of available resources that provide guidance on statistical modeling techniques.6 M&V

costs can quickly escalate, so use of M&V to validate energy savings should be used sparingly.

And where used, M&V costs should be minimized through the use of statistical sampling

techniques.

16.5 Quality Assurance and Savings Validation

Whether or not a custom measure will realize its savings potential is dependent upon the

measure being properly installed, commissioned, and operating as predicted (in the savings

commissioning guidelines. See Section 14 – References.



ers

analysis). The following approaches are used to ensure the measure is achieving, or is capable

of achieving, energy savings.

Pre-Implementation

Documentation review – The measure should be properly documented, as described in

the following section. The documentation should be examined to ensure that it is complete

and that it provides all essential information for verifying savings estimates.

Site pre-inspection and interviews – Site inspections may be conducted to verify

preexisting conditions, quantities of measures, key operating parameters, equipment

performance, and baseline assumptions in the measure documentation.

Measured data collection – To address uncertainties regarding the performance of the

measure or to confirm the validity of assumptions used in the baseline analysis, spot

measurements, data trending (via data loggers or building control systems), or other

performance tests may be conducted before the measure is implemented. Pre-

implementation measured data is also collected if required as part of an M&V approach to

estimating savings.

Post-Implementation

Documentation retention – All program-required documents should be reviewed to

ensure they are accurate and complete. All energy savings-related documentation should

be retained for future savings validation or evaluation efforts.

Site post-inspection and interviews – Site inspections and interviews may be conducted

to verify that the measure was installed, commissioned, and operating as intended.

Measured data collection – Spot measurements or data trending may be conducted to

verify measure key operating parameters, or to meet the requirements of an M&V plan.

Third-party evaluation – The measure may be evaluated as part of a program evaluation

to verify energy savings.

16.6 Documentation

Proper documentation of custom measures is essential for demonstrating the reliability of

reported measure energy savings. A fully documented measure helps to ensure the measure is

installed and operating as intended. It will also help optimize program evaluation efforts by

providing evaluators with the necessary information that is needed to verify savings estimates.

A fully documented measure consists of a measure description, energy savings summary,

baseline description, savings calculations, and a summary of quality assurance activities.

Table 16-1 provides a template for guiding program administrators through the

documentation process.

Provisional Measures 17


ers

17. PROVISIONAL MEASURES

This section provides savings estimates for provisional measures. Provisional savings measures

are measures that do not yet meet the reliability standard of a UES measure. The most typical

are emerging technology or newly adopted program measures that exhibit significant energy

saving potential. Provisional measures may also include measures that have a minor impact

on overall program savings for which UES savings estimates are not yet available. Provisional

savings estimates provide an interim solution for reporting measure savings while testing,

evaluation, or demonstration efforts are under way to validate energy savings estimates.

Savings estimates for provisional measures have a higher degree of uncertainty than UES

estimates and are expected to be updated by current or future studies and evaluations. Given

the temporary nature of the savings estimate, each provisional measure is assigned a sunset

date after which the savings estimate should be updated or other sources or credible savings

estimates should be used. Future TRM updates will either revise the savings estimates and set a

new sunset date, revise the measure savings estimates and reclassify the measure as a UES

measure, or remove the measure. Revised savings will be based on the most current and best

available data.

The savings estimates provide a simplified approach for reporting measure savings. The

savings estimates are considered a secondary option when compared to savings estimates that

are validated through program measurement and verification.

It’s anticipated that provisional savings estimates will account for a relatively small portion of a

program administrator’s reported savings. Program administrators should track the percentage

of savings reported that are based on provisional savings estimates. If the percentage exceeds a

specified amount, it should be reported in the program’s annual regulatory compliance report

along with a plan of action for reducing the uncertainty in the reported savings.

Key Parameters for Estimating Savings

HVAC cooling capacity The HVAC unit nominal capacity or size, in tons, is needed to estimate measure savings. If the unit size is unknown, then the conditioned area served by the unit may be used to estimate savings

Square foot of conditioned area

The conditioned area may be used to estimate measure savings.

HVAC unit type The type of HVAC unit should be obtained. Applicable HVAC types are electric cooling only, electric cooling/gas heating, and all-electric air source heat pump units.

Existing thermostat type The thermostat make and model should be obtained to confirm thermostat capabilities and obtain other relevant data, such as wiring diagrams

Existing thermostat programmable settings

The thermostat operating status (e.g., in programming mode, in manual bypass) should be obtained as well as the currently used programmable settings. This information will be useful for evaluating and validating program savings



ers

Program Design and Eligibility Considerations

Eligible thermostats should have advanced programming capabilities and be accessible via the Internet. Users should be required to maintain an Internet connection to the thermostat and be encouraged to regularly use its reporting and alarm features. Program administrators may also wish to limit or prohibit replacement of existing programmable thermostats where the thermostat’s operating schedules and temperature setbacks are being used effectively.

Savings Estimate Expiration Date

The savings estimates for this measure are provisional and expire on June 30, 2017. At that time, the savings estimates should be revised and updated based on the best available data.

There are a number of studies that are either ongoing or in the planning stages that are expected to provide recommendations on the best way to estimate and report program savings. In addition, the studies should identify and provide best practices for effective program design and implementation.

17.4 Tier II Advanced Power Strips – Residential


Measure description Replacement of a standard electric power strip with a new Tier II advanced power strip (Tier II APS)

End use Residential – for controlling audio video home entertainment equipment

Measure eligibility Qualifying products must be tested in both lab and field trials to demonstrate performance and savings potential


Unit energy savings 212 kWh per unit1


EUL 5 years1



Baseline description A standard power strip that supplies electric power to a minimum of two AV devices with at least one being a television

Efficient case description A Tier II APS controlling power to a minimum of two AV devices with at least one being a television

Savings Calculation


Savings are derived from field trial test data.1

Peak demand reduction 0.003 kW

Definitions Currently, there are no industry-standard specifications for Tier II APS devices. The University of California, Irvine’s California Plug Load Research Center (CALPLUG) has suggested that the devices at a minimum have the following features:

Usage sensing – provide at least one method to sense and determine consumer utilization and usage patterns

Advanced power analysis – in addition to voltage and current sensing, the device must perform advanced power analysis, including true root mean square power analysis, power factor analysis, and load signature detection

Control algorithms – perform automated power management of connect devices based on data and information acquired


AV entertainment equipment controlled by the device

Savings are relative to the amount of power controlled by the device.

Equipment use patterns Savings are achieved by powering down equipment after a period (typically 1 hour) of inactivity

Behavior User acceptance of device is essential to the persistence of savings


Eligible Tier II devices should meet the performance and test recommendations of an independent testing or research agency, such as CALPLUG. Program administrators should consider ways to ensure that the device is properly installed and controls at a minimum one television and one other AV device such as a DVD player, cable box, or surround sound system. Program administrators should also consider ways to ensure the device is not removed, or verify installation and persistence of use by conducting post installation evaluation.


The savings estimates for this measure are provisional and expire on June 30, 2018. At that time, the savings and effective useful life of the measure should be revised based on ongoing tests, evaluations, and studies.

17.5 Home Energy Reports – Residential


Measure description Behavioral program – delivery of monthly energy reports that are designed to influence customers to reduce energy use by providing comparisons to efficient and similar homes.

End use Residential – comprehensive

Measure eligibility Applicable to residential home energy reports that provide feedback, comparisons, and efficiency suggestions based on monthly electric and/or natural gas energy use.

Savings type Custom – provisional

Program savings are reported using the custom input section of the POU reporting tool (currently the E3 reporting tool spreadsheet)

Unit energy savings 1.48% of annual electric energy use1

0.60% of annual natural gas energy use2

The preferred approach for estimating program-specific savings is to conduct randomized control trial (RCT) evaluation. Other saving estimate methods are being explored that may eventually be proven to produce comparable results.

Incremental measure cost Program administrator implementation costs for the program

EUL 1 year.

It’s possible that savings could persist beyond the treatment (i.e., delivery of monthly reports), which would result in a EUL greater than 1. However, persistence of savings has not yet been substantiated to a degree that would allow for the use of default persistence assumptions. Additionally, reporting annual savings estimates with EULs greater than 1 year requires adjustment of savings claimed in future years should the program operate for more than 1 year.



Baseline description Nonparticipant in the program (does not receive home energy reports)

Efficient case description Customer receives monthly energy reports
