This version of the Texas Technical Reference Manual was primarily developed from program documentation and measure savings calculators used by the Texas Electric Utilities and their Energy Efficiency Services Providers (EESPs) to support their energy efficiency efforts, and original source material from petitions filed with the Public Utility Commission of Texas by the utilities, their consultants and EESPs such as Frontier Associates (TXu 1-904-705), ICF, CLEAResult and?Nexant. Portions of the Technical Reference Manual are copyrighted 2001-2015 by the Electric Utility Marketing Managers of Texas (EUMMOT), while other portions are copyrighted 2001-2015 by Frontier Associates. Certain technical content and updates were added by the EM&V team to provide further explanation and direction as well as consistent structure and level of informationTRM Technical SupportTechnical support and questions can be emailed to the EM&V project manager (lark.lee@) and PUCT staff (katie.rich@puc.).Introduction This volume of the TRM contains the deemed savings for nonresidential measures that have been approved for use in Texas by the PUCT. This volume includes instructions regarding various savings calculators and reference sources of the information. The TRM serves as a centralized source of deemed savings values; where appropriate, Measurement & Verification (M&V) methods by measure category are noted for informational purposes only regarding the basis of projected and claimed savings. REF _Ref371061506 \h Table 11 provides an overview of the nonresidential measures contained within Volume 3 and the types of deemed savings estimates available for each one. There are four types of deemed savings estimates identified: Point estimates that provide a single deemed savings value that correspond to a single measure or type of technology. Deemed saving tables that provide energy and peak savings as a function of size, capacity; building type, efficiency level, or other inputs.Savings algorithms that require user defined inputs that must be gathered on site and the identification of default inputs where primary data could not be collected. In many cases, these algorithms are provided as references to deemed savings tables, point estimates, or calculator explanations. Calculators are used by different utilities and implementers to calculate energy savings for different measures. In many cases, there are several different calculators available for a single measure. Sometimes their background calculators are similar, and in other cases, estimates can vary greatly between each calculator. M&V methods are also used for some measures to calculate savings in the event that standard equipment is not used, or the specified building types do not apply. For some of these measures, both a simplified M&V approach and a full M&V approach may be allowed by the utility. M&V methods as a source of claimed and projected savings are noted for informational purposes only. Standardized M&V approaches that have been reviewed by the EM&V team are incorporated into Volume 4: Measurement & Verification Protocols of this TRM. Please consult Volume I: Overview and User Guide, Section 4: Structure and Content, for details on the organization of the measure templates presented in this volume.

This TRM Measure ID covers the following lighting technologies:Linear Fluorescent T5s, and High-Performance or Reduced Watt T8s. Linear fluorescent measures may also involve delamping with or without the use of pact Fluorescent Lamp (CFL) screw-based lamps and hard-wired pin-based fixtures Induction lampsPulse-start (PSMH) and Ceramic Metal Halide (CMH) lamps, and other High Intensity Discharge (HID) lamps.Light Emitting Diode (LED) screw-based lamps and hard-wired LED fixturesEnergy and demand savings are based on operating hours, coincident-load factors, and changes in pre-existing and post-installation lighting loads as determined using an approved lighting Standard Fixture Wattage table (see the Lighting Survey Form). The Lighting Survey Form (LSF) is one example of a calculator that is used to determine energy and demand savings. Pre and post-retrofit lighting inventories are entered and used with the pre-loaded stipulated values and algorithms needed to calculate energy and demand savings. Components of the calculator include:Instructions and Project Information Pre and Post-retrofit lighting inventories. A tab for exempt fixtures, and a description of the exemptions, is also present in this calculator.Fixture descriptions are selected from a Standard Fixture Wattage table.Factor Tables which contain stipulated operating hours, coincidence factors, and interactive HVAC factors.A Summary tab, where the final energy and demand calculations are displayed. The data from this tab is entered into the utility program tracking data as the claimed savings values.Although the generic Lighting Survey Form calculator is available to all entities on the Texas Energy Efficiency website, several utilities have their own versions.Eligibility Criteria This section describes the system information and certified wattage values that must be used to estimate energy and peak savings from lighting systems installed as part of the Texas utility energy efficiency programs. The fixture codes and the demand values listed in the Table of Standard Fixture Wattages are used in calculating energy and demand savings for lighting efficiency projects. In addition, LED and linear fluorescent T8s need to be certified, as follows:High-performance (HP) and reduced-watt (RW) T8 linear fluorescent lamps and ballasts need to be certified by the Consortium for Energy Efficiency (CEE). Links for both HPT8s and RWT8s are provided on the Texas Energy Efficiency website.LED lamps and fixtures must be certified and listed by at least one of the following organizations: DesignLights Consortium (DLC), ENERGY STAR?, Lighting Design Lab (LDL), or DOE LED Lighting Facts.? Links to these organizations and their certified LED equipment lists are provided on the Texas Energy Efficiency website. Additionally, at the utilities discretion, LED products may receive approval if results of independent lab testing (e.g. LM-79, LM-80, TM-21, ISTMT) show the products comply with the most current version of the DLC Technical Requirements.Exempt Lighting for New Construction. Some types of new construction lighting fixtures are exempt from inclusion in the interior lighting demand savings calculation, but they are still included in the total installed lighting power calculations for a project. Exempt fixtures are those that do not provide general/ambient/area lighting, have separate control devices, and are installed in one of the following applications:The connected power associated with the following lighting equipment is not included in calculating total connected lighting power.Professional sports arena playing-field lighting.Sleeping-unit lighting in hotels, motels, boarding houses, or similar buildings.Emergency lighting automatically off during normal building operation.Lighting in spaces specifically designed for use by occupants with special lighting needs including visual impairment and other medical and age-related issues.Lighting in interior spaces that have been specifically designated as a registered interior historic landmark.Casino gaming areas.Lighting equipment used for the following shall be exempt provided that it is in addition to general lighting and is controlled by an independent control device:Task lighting for medical and dental purposes.Display lighting for exhibits in galleries, museums, and monuments.Lighting for theatrical purposes, including performance, stage, film production, and video production.Lighting for photographic processes.Lighting integral to equipment or instrumentation and installed by the manufacturer.Task lighting for plant growth or maintenance.Advertising signage or directional signage.In restaurant building and areas, lighting for food warming or integral to food preparation equipment.Lighting equipment that is for sale.Lighting demonstration equipment in education facilities.Lighting approved because of safety or emergency considerations, inclusive of exit lights.Lighting integral to both open and glass-enclosed refrigerator and freezer cases.Lighting in retail display windows, provided the display area is enclosed by ceiling height partitions.Furniture-mounted supplemental task lighting that is controlled by automatic shut off.Baseline ConditionThe baseline condition or assumed baseline efficiency used in the savings calculations depends on the decision type used for the measure. For new construction, the baseline will be based on a Lighting Power Density (LPD) in watts per square foot by building type, as specified by the relevant energy code/standard applied to a specific project. For retrofit applications, the baseline efficiency would typically reflect the in-situ, pre-existing equipment, with the exception of linear fluorescent T12s and first generation T8s as explained below. Fixture wattages used for the savings calculations are determined from the Table of Standard Fixture Wattages. Linear Fluorescent T12 Special Conditions The U.S. Energy Policy Act of 1992 (EPACT) set energy efficiency standards that preclude certain lamps and ballasts from being manufactured or imported into the U.S. The latest standards covering general service linear fluorescents went into full effect July 2014. Under this provision, almost all 4-foot and some 8-foot T12 lamps, as well as first-generation 4-foot, 700?series T8 lamps were prohibited from manufacture. Because all lighting equipment for Texas energy efficiency programs must be EPACT compliant, including existing or baseline equipment, adjustments were made to the T12 fixtures in the Standard Fixture Wattage table. Certain T12 lamp/ballast combinations which are non-EPACT compliant are assigned EPACT demand values. As such, 4-foot and 8-foot T12s are no longer an approved baseline technology for Texas energy efficiency programs. 4-foot and 8-foot T12s are still eligible for lighting retrofit projects, but an assumed electronic T8 baseline will be used for estimating the energy and demand savings instead of the existing T12 equipment. T12 fixtures will remain in the Standard Fixture Wattage list, but the label for these records will be changed to “T12 (T8 baseline)” and the fixture wattage for these records will be adjusted to use the adjusted fixture wattages shown in REF _Ref410804186 Table 21.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 1: Adjusted Baseline Wattages for T12 EquipmentT12 LengthLampCountRevised Lamp WattageRevisedSystem Wattage48 inch – Std, HO, and VHO(4 feet)13231232583328543211263217083222496 inch - Std(8 feet)60/75W15969259110359179459219659330859438+*96 inch-HO and VHO(8 feet)95/110W1861012861603862614863196864818866382 ft U-Tube132322326033289* Value approximated using linear interpolation.*+ 8 lamp fixture wattage approximated by doubling 4 lamp fixture wattage.Key: HO = high output, VHO = very high outputHigh-Efficiency ConditionAcceptable efficient fixture types are specified in the Table of Standard Fixture Wattages. In addition, some technologies such as LEDs must meet the additional requirements specified under Eligibility Criteria.High-Efficiency/Performance Linear Fluorescent T8s All post-retrofit technologies and new construction must use Reduced Wattage T8 systems or High Performance T8 systems that meet the High Performance and Reduced Wattage lamp and ballast efficiency specifications developed by the Consortium for Energy Efficiency (CEE) as published on its website. This is a requirement for all T8 system projects. In addition, iIf CEE does not have efficiency guidelines for a T8 system (such as for 8-foot, 3-foot, 2-foot, and U-bend T8 products), the product must have higher light output or reduced wattage than its standard equivalent product (minimum efficacy of 75 mean lumens per watt), while also providing a higher CRI (color rendition index) greater than 80, and a n average rated life of 24,000 hours at 3 hours per starthigher rated lamp life, and an equivalent or higher initial and mean lumen output per lamp. In addition, 2-foot and 3-foot ballasts must also use electronic ballasts manufactured after November 2014.Energy and Demand Savings MethodologySavings Algorithms and Input VariablesThis section describes the deemed savings methodology for both energy and demand savings for all lighting projects. The savings are calculated in separate methods for retrofit projects and new construction projects, and both are described below.

One example of a Table of Standard Fixture Wattages can be found in the Lighting Survey Form maintained on the Texas Energy Efficiency website. This table is used to assign identification codes and demand values (watts) to common fixture types (fluorescent, incandescent, HID, LED, etc.) used in commercial applications. The table is subdivided into lamp types such as linear fluorescent, compact fluorescent, mercury vapor, 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. A legend explains the rules behind the fixture codes.Each record also includes a description of the fixture, the number of lamps, the number of ballasts if applicable, and the fixture wattage. 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. The table is usually updated periodically as new fixtures are added.The fixture codes and the demand values listed in the watt/fixture column in the Table of Standard Fixture Wattages are used in calculating energy and demand savings for any lighting efficiency project. There are two versions of the Table of Standard Fixture Wattages (Frontier and Nexant). Having a common master table in a single location would make it easier to maintain and add new fixtures, and more importantly ensure consistent savings are used for the same lighting measure across the state. However, an alternative approach would be to compare all standard wattage tables being used as part of the evaluation effort, identify differences, and choose the one that is most correct.For implementers interested in adding new fixtures to Frontier’s lighting table, a request should be submitted to Frontier. The request should include all information required to uniquely identify the fixture type and to fix its demand, as well as other contextual information needed for the table. If possible, the request should also be supported by manufacturer’s ANSI test data. Frontier then periodically releases updates of the table.New Construction: Lighting Power Density Table. For new construction projects, the post-retrofit lighting wattages are determined as they are for the existing construction projects, from the Standard Fixture Wattage table. However, the baseline wattage is determined from the treated floor area and a lighting power density (LPD) value, which are the allowable watts per square foot of lit floor area as specified by the relevant energy code. These values are presented in REF _Ref367729731 Table 22.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 2: New Construction LPDs by Building TypeFacility TypeLighting Power Density ( W/ft2)Facility TypeLighting Power Density ( W/ft2)Automotive Facility0.90Office1.00Convention Center1.20Outdoor Uncovered Parking Area: Zone 10.04Courthouse1.20Outdoor Uncovered Parking Area: Zone 20.06Dining: Bar/Lounge/Leisure1.30Outdoor Uncovered Parking Area: Zone 30.10Dining: Cafeteria1.40Outdoor Uncovered Parking Area: Zone 40.13Dining: Family1.60Parking Garage0.30Dormitory1.00Penitentiary1.00Exercise Center1.00Performing Arts1.60Gymnasium1.10Police/Fire Stations1.00Health Care – Clinic1.00Post Office1.10Hospital1.20Religious Buildings1.30Hotel1.00Retail1.50Library1.30School/University1.20Manufacturing1.30Sports Arena1.10Motel1.00Town Hall1.10Motion Picture1.20Transportation1.00Multi-Family0.70Warehouse0.80Museum1.10Workshop1.40In REF _Ref367729731 Table 22 above, the zones used for the Outdoor Uncovered Parking Areas are:Zone 1: Developed areas of national parks, state parks, forest lands, and rural areasZone 2: Areas predominantly consisting of residential zoning, neighborhood business districts, light industrial with limited night-time use, and residential mixed use areasZone 3: All other areasZone 4: High-activity commercial districts in major metropolitan areas as designated by the local land use planning authorityOperating Hours (Hours) and Coincidence Factors (CFs)Operating hours and peak demand coincidence factors are assigned by building type, as shown in Table 2-3.

Slight variations to these are found in other calculators and program manuals. A set of comparisons of HOU and CF across utilities are found in Appendix C. Interactive HVAC Factors (HVAC energy, demand)Basic lighting savings are adjusted to account for the lighting system interaction with HVAC systems in conditioned or refrigerated spaces. A reduced lighting load reduces the internal heat gain to the building, which reduces the air conditioning/cooling load but it also increases the heating load. Currently, the TRM only considers the additional cooling savings, and the heating penalty or increase in usage is ignored. As REF _Ref367732228 Table 24 shows, four conditioned space types are used for the Texas programs. There is a single air-conditioned space type and two options for commercial refrigeration type spaces like walk-in coolers and refrigerated warehouses: Medium and Low temperature. Utility procedures state that if the actual application falls between these values, that the higher temperature value should be used. The final space type is unconditioned (or more explicitly uncooled as the focus is on cooling). In the lighting calculators, these values are typically assigned at the line-item level based on the conditioning type for the space in which the fixtures are located.

For retrofit applications, lighting controls would typically be installed where there is no control other than a manual switch (wall or circuit panel). For new construction lighting systems, they would be added where they are not already required by existing energy or building codes. Promoted technologies include occupancy sensors and daylight dimming controls. Energy and peak demand savings are calculated for these technologies via an energy adjustment factor (EAF) for kWh, and a power adjustment factor (PAF) for kW. Eligibility CriteriaMeasures installed through utility programs must be one of the occupancy sensor, daylighting, and tuning controls that are described in Table 2-7.Baseline Condition The baseline condition assumes no existing or code required (new construction) automatic lighting controls are installed on the existing lighting fixtures (i.e. they are only manually switched).High-Efficiency ConditionThe energy-efficient condition is properly installed (not bypassed or overridden) and calibrated lighting controls that control overhead lighting in a facility based on occupancy, day lighting, or tuning sensors.Energy and Demand Savings MethodologySavings Algorithms and Input Variables The equations for lighting controls are similar to those used for lighting lamps and fixtures, with the addition of the EAF and PAF multipliers, as shown below. Additionally, the pre/post k/W difference is replaced by a single kW value (the total fixture wattage controlled by the device).Energy Savings= kWcontrolled×EAF×Hours×HVACenergyEquation SEQ Equation \* ARABIC 5Peak Summer Demand Savings=kWcontrolled×PAF×CF×HVACdemandEquation SEQ Equation \* ARABIC 6Where:kWcontrolled=Total kW of controlled fixtures (Fixture wattage from Standard wattage table multiplied by quantity of fixtures)Hours=Hours by building type from Table 2-3EAF= Lighting control Energy Adjustment Factor, see Table 2-8PAF= Lighting control Power Adjustment Factor, see Table 2-8CF= Coincidence factor by building type, see Table 2-3HVACenergy=Energy Interactive HVAC factor by building type, see REF _Ref367732228 \h \* MERGEFORMAT Table 24HVACdemand= Demand Interactive HVAC factor by building type, see REF _Ref367732228 \h \* MERGEFORMAT Table 24See the 2.1.1 Lighting – Lamps and Fixtures measure overview section for a full explanation of the non-control variables and their corresponding values.

For example, a factor of 0.24 would equate to a 24% energy and demand savings. Note that in previous TRM versions, the EAFs and PAFs were different values obtained from different sources. The same values from the referenced LBNL study are used for both EAF and PAF factors due to the lack of published data for demand factors.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 7: Lighting Controls DefinitionsControl TypeDescriptionNoneNo controlOccupancyAdjusting light levels according to the presence of occupants-Wall or Ceiling-Mounted Occupancy Sensors-Integrated Fixture Occupancy Sensors-Time Clocks-Energy Management SystemsDaylighting(Indoor)Adjusting light levels automatically in response to the presence of natural light-PhotosensorsOutdoorOutdoor on/off photosensor/time clock controls; no savings attributed because already required by codePersonalTuningAdjusting individual light levels by occupants according to their personal preference; applies to private offices, workstation-specific lighting in open-plan offices, and classrooms-Dimmers-Wireless ON/OFF switches-Personal computer based controls-Pre-set scene selectionInstitutionalTuningAdjustment of light levels through commissioning or provision of switches or controls for areas or groups of occupants-Dimmable ballasts-On/Off or dimmer switches for non-personal tuningMultiple TypesAny combination of the types described aboveTable STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 8: Lighting Controls Energy and Power Adjustment FactorsControl TypeSub-CategoryControl CodesEAFPAFNonen/aNone0.000.00Occupancyn/aOS0.240.24Daylighting(Indoor)Continuous dimmingDL-Cont0.280.28Multiple step dimmingDL-StepON/OFFDL-ON/OFFOutdoorn/aOutdoor0.000.00Personal Tuningn/aPT0.310.31Institutional Tuningn/aIT0.360.36Multiple/Combined TypesVarious combinationsMultiple0.380.38Deemed Energy and Demand Savings TablesThis section is not applicable.Claimed Peak Demand SavingsRefer to Volume 1, Appendix B: Peak Demand Reduction Documentation for further details on peak demand savings and methodology.Measure Life and Lifetime SavingsThe estimated useful life (EUL) for lighting controls is provided by the 2007 GDS Associates Report:Occupancy Sensor: 10 yearsDaylighting Control: 10 yearsTime Clock: 10 yearsTuning Control: 10 yearsProgram Tracking Data & Evaluation RequirementsPrimary inputs and contextual data that should be specified and tracked by the program database to inform the evaluation and apply the savings properly are: Building TypeDecision/Action Type: Retrofit or NCConditioned Space Type: cooling equipment type, refrigerated space temperature range, heating fuel type (specified per control)Location of Controlled Lighting: Interior or Exterior (specified per control)Baseline Lighting Control Type CodeInstalled Lighting Control Type CodeLighting Control Mount Type: Wall, Ceiling, Integrated Fixture, etc.Lighting Control Specification SheetsControlled Fixture ConfigurationControlled Fixture Lamp TypeControlled Fixture WattageReferences and Efficiency StandardsPetitions and Rulings“A Meta-Analysis of Energy Savings from Lighting Controls in Commercial Buildings”.

Nonresidential: HVAC Split System/Single Packaged Air Conditioners and Heat Pumps Measure OverviewTRM Measure ID: NR-HV-PSMarket Sector: CommercialMeasure Category: HVAC Applicable Building Types: See Table 2-18 through Table 2-22 Fuels Affected: Electricity Decision/Action Type: Replace-on-Burnout (ROB), Early Retirement (ER), and New Construction (NC)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings Calculation Savings Methodology: CalculatorMeasure DescriptionThis section summarizes the deemed savings methodology for the installation of air-cooled Split System and Single Packaged Air Conditioning (AC) and Heat Pump (HP) systems. This document covers assumptions made for baseline equipment efficiencies for early retirement (ER) based on the age of the replaced equipment, and replace-on-burnout (ROB) and new construction (NC) situations based on efficiency standards. Savings calculations incorporate the use of both full-load and part-load efficiency values. For ER, the actual age of the baseline system should be determined from the equipment nameplate or other physical documentation whenever possible. In the event that the actual age of the unit is unknown, default values are provided.Applicable efficient measure types include:Packaged and Split air conditioners (DX or air-cooled)Packaged and Split heat pumps (air-cooled)System Type Conversions. Retrofits involving a change from a chiller-based system to a packaged/split system are also covered under this measure. In the event that this type of retrofit is performed, the tables from the HVAC Chillers measure will need to be referenced.Eligibility CriteriaFor a measure to be eligible to use this deemed savings approach, the following conditions must be met:The existing and proposed cooling equipment are electric.The climate zone is determined from the county-to-climate-zone mapping table.The building falls into one of the categories listed in Table 2-28 through Table 2-22. Building type descriptions and examples are provided in REF _Ref428187133 \h \* MERGEFORMAT Table 216 and REF _Ref433116522 Table 217.For early retirement projects: ER projects involve the replacement of a working system that is at least five years old before natural burnout. Additionally, the ER approach cannot be used for projects involving a renovation where a major structural change or internal space remodel has occurred. An ROB approach should be used for these scenarios.In the event that these conditions are not met, the deemed savings approach cannot be used, and the Simplified M&V Methodology or the Full M&V Methodology must be used.Baseline ConditionThe baseline conditions related to efficiency and system capacity for early retirement and replace-on-burnout/new construction are as follows:Early RetirementEarly retirement systems involve the replacement of a working system, prior to natural burnout. The early retirement baseline cannot be used for projects involving a renovation where a major structural change or internal space remodel has occurred.Two baseline condition efficiency values are required for an ER scenario, one for the ER (RUL) period and one for the ROB (EUL-RUL) period. For the ROB period, the baseline efficiency is the same as for an ROB/NC scenario. For the ER period, the baseline efficiency should be estimated using the values from Table 2-10 through Table 2-14 according to the capacity, system type, and age (based on year of manufacture) of the replaced system. When the system age can be determined (from a nameplate, building prints, equipment inventory list, etc.), the baseline efficiency levels provided in Table 2-10 through Table 2-14 should be used. These tables will be updated every few years so that systems greater than five years old will be eligible for early retirement. When the system age is unknown, assume an age of 17 years.Regarding the ER baseline efficiency tables, PUCT Docket 40885 provided baseline efficiencies for split and packaged systems replaced via early retirement programs, and included a category for 1990-1991. However, common practice for energy efficiency programs in Texas is to allow systems older than 1990 to use the same baseline efficiencies as those listed for 1990-1991. This practice is reflected in the ER baseline efficiency tables, by showing the Year Installed as “≤ 1991” rather than 1990-1991.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 10: ER Baseline Full-Load Efficiency for ACsYearInstalled(ReplacedSystem)SplitSystems< 5.4 tons[EER]PackageSystem< 5.4 tons[EER]AllSystems5.4 to< 11.3 tons[EER]AllSystems11.3 to< 20 tons[EER]AllSystems20 to< 63.3 tons[EER]AllSystems> 63.3 tons[EER]≤ 19919.29.08.98.08.07.81992 – 20019.29.08.98.38.38.02002 – 20059.29.010.19.59.39.02006 – 200911.211.210.19.59.39.02010 – 201111.211.211.010.89.89.5Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 11: ER Baseline Part-Load Efficiency for ACsYearInstalled(ReplacedSystem)SplitSystems< 5.4 tons[SEER]PackageSystem< 5.4 tons[SEER]AllSystems5.4 to< 11.3 tons[IEER]AllSystems11.3 to< 20 tons[IEER]AllSystems20 to< 63.3 tons[IEER]AllSystems> 63.3 tons[IEER]≤ 199110.09.79.18.28.17.91992 – 200110.09.79.18.58.48.12002 – 200510.09.710.39.79.49.12006 – 200913.013.010.39.79.49.12010 – 201113.013.011.211.09.99.6Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 12: ER Baseline Full-Load Cooling Efficiency for HPsYearInstalled(ReplacedSystem)SplitSystems< 5.4 tons[EER]PackageSystem< 5.4 tons[EER]AllSystems5.4 to< 11.3 tons[EER]AllSystems11.3 to< 20 tons[EER]AllSystems20 to< 63.3 tons[EER]AllSystems> 63.3 tons[EER]≤ 19919.29.08.98.08.07.81992 – 20019.29.08.98.38.38.52002 – 20059.29.09.99.18.88.82006 – 200911.211.29.99.18.88.82010 – 201111.211.210.810.49.39.3Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 13: ER Baseline Part-Load Cooling Efficiency for HPsYearInstalled(ReplacedSystem)SplitSystems< 5.4 tons[SEER]PackageSystem< 5.4 tons[SEER]AllSystems5.4 to< 11.3 tons[IEER]AllSystems11.3 to< 20 tons[IEER]AllSystems20 to< 63.3 tons[IEER]AllSystems> 63.3 tons[IEER]≤ 199110.09.79.18.18.17.91992 – 200110.09.79.18.48.48.62002 – 200510.09.710.19.28.98.92006 – 200913.013.010.19.28.98.92010 – 201113.013.011.010.59.49.4Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 14: ER Baseline Heating Efficiency for HPsYear Installed(ReplacedSystem)Split Systems< 5.4 tons[HSPF]Package System< 5.4 tons[HSPF]All Systems5.4 to < 11.3 tons[COP]All Systems> 11.3 tons [COP]≤ 19986.86.63.03.01999 – 20006.86.63.02.92001 – 20056.86.63.23.12006 – 20097.77.73.23.12010 – 20117.77.73.33.2Replace-on-Burnout (ROB) and New Construction (NC):Baseline efficiency levels for package and split DX air conditioners and heat pumps are provided in REF _Ref410912639 Table 215.

Early Retirement The high-efficiency retrofits must meet the following criteria:For early retirement projects only, the installed equipment cooling capacity must be within 80% to 120% of the replaced electric cooling capacityNo additional measures are being installed that directly affect the operation of the cooling equipment (i.e., control sequences, cooling towers, and condensers).Energy and Demand Savings MethodologySavings Algorithms and Input VariablesEnergy Savings kWhsavings=kWhSavings,C+kWhSavings,HEquation SEQ Equation \* ARABIC 7Peak Demand [kWSavings,C]=CapC,preηbaseline,C-CapC,postηinstalled,C×CF×1 kW1,000 WEquation SEQ Equation \* ARABIC 8Energy Cooling kWhSavings,C=CapC,preηbaseline,C-CapC,postηinstalled,C×EFLHC×1 kW1,000 WEquation SEQ Equation \* ARABIC 9Energy Heating kWhSavings,H=CapH,preηbaseline,H-CapH,postηinstalled,H×EFLHH×1 kWh3,412 BtuEquation SEQ Equation \* ARABIC 10Where:CapC/H,pre=Rated equipment cooling/heating capacity of the existing equipment at AHRI standard conditions [Btuh]; 1 ton = 12,000 BtuhCapC/H,post=Rated equipment cooling/heating capacity of the newly installed equipment at AHRI standard conditions [Btuh]; 1 ton = 12,000 Btuhηbaseline,C= Cooling efficiency of existing equipment (ER) or standard equipment (ROB/NC) [Btuh/W]ηinstalled,C=Rated cooling efficiency of the newly installed equipment (kW/Ton) - (Must exceed ROB/NC baseline efficiency standards in REF _Ref401839252 Table 215) [Btuh/W]ηbaseline,H= Heating efficiency of existing equipment (ER) or standard equipment (ROB/NC) [COP]ηinstalled,H=Rated heating efficiency of the newly installed equipment (Must exceed baseline efficiency standards in REF _Ref401839252 Table 215) [COP]Note: Use EER for kW savings calculations and SEER/IEER and COP for kWh savings calculations.

However, ER projects require a weighted savings calculated over both the ER and ROB periods taking the EUL and RUL into account. The ER savings are applied over the remaining useful life (RUL) period, and the ROB savings are applied over the remaining period (EUL-RUL). The final reported savings for ER projects are not actually a “first-year” savings, but an “average annual savings over the lifetime (EUL) of the measure”. These savings calculations are explained in Appendix D.Deemed Energy and Demand Savings TablesDeemed peak demand coincidence factor (CF) and equivalent full-load hour (EFLH) values are presented by building type and climate zone. A description of the building types that are used for HVAC systems are presented in REF _Ref428187133 Table 216 and REF _Ref433116522 Table 217. These building types are derived from the EIA CBECS study. The CF and EFLH values for packaged and split AC and HP units are presented in Table 2-18 through Table 2-22. These tables also include an “Other” building type, which can be used for business types that are not explicitly listed. The CF and EFLH values used for Other are the most conservative values from the explicitly listed building types.? When the Other building type is used, a description of the actual building type, the primary business activity, the business hours, and the HVAC schedule must be collected for the project site, and stored in the utility tracking data system.For those combinations of technology, climate zone, and building type where no values are present, a project with that specific combination cannot use the deemed approach.A description of the calculation method used to derive these values can be found in Docket No. 40885, Attachment B.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 16: Commercial HVAC Building Type Descriptions and ExamplesBuilding TypePrincipal Building ActivityDefinitionDetailed Business Type ExamplesEducationCollegeBuildings used for academic or technical classroom instruction, such as elementary, middle, or high schools, and classroom buildings on college or university campuses.

Prior to filing of Docket 41070, deemed savings for what is now climate zone 5 were the Climate Zone 2 deemed savings. Due to significant differences between the values for CZ5 filed in Docket 41070 relative to the values for the other CZs, the values for CZ2 are used here for CZ5.? This change also expands the coverage of building types and HVAC systems type for CZ5.Claimed Peak Demand SavingsA summer peak period value is used for this measure. Refer to Volume 1, Appendix B: Peak Demand Reduction Documentation for further details on peak demand savings and methodology. Measure Life and Lifetime SavingsThe EUL and RULs for this HVAC equipment are provided below. The reader should refer to the definitions of effective useful life and remaining useful life in the glossary in Volume 1 for guidance on how to determine the decision type for system installations. Effective Useful Life (EUL)The EUL for Split and Packaged Air Conditioners and Heat Pumps is 15 years. Remaining Useful Life (RUL) The RUL of replaced systems is provided according to system age in REF _Ref373761639 \h Table 223. As previously noted, for ER units of unknown age, a default value of 17 years should be used. Both the RUL and EUL are needed to estimate savings for early retirement projects for two distinct periods: The ER period (RUL) and the ROB period (EUL - RUL). The calculations for early retirement projects are extensive, and as such are provided in Appendix D.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 23: Remaining Useful Life Early Retirement SystemsAge in Years of Replaced SystemSplit and Packaged A/C and HP Systems [years]Age in Years of Replaced SystemSplit and Packaged A/C and HP Systems [years]51015 2.869.1162.578.2172.287.3181.996.5191.7105.7201.5115.0211.3124.4221.1133.8231.0143.3Program Tracking Data & Evaluation RequirementsThe below list of primary inputs and contextual data is recommended to be specified and tracked by the program database to inform the evaluation and apply the savings properly.

Table 236Fuels Affected: Electricity Decision/Action Type: Replace on Burnout (ROB), Early Retirement (ER), and New Construction (NC)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings CalculationSavings Methodology: CalculatorMeasure DescriptionThis document presents the deemed savings methodology for the installation of chillers. This document covers assumptions made for baseline equipment efficiencies for early retirement (ER) based on the age of the replaced equipment, and replace-on-burnout (ROB) and new construction (NC) situations based on efficiency standards. Savings calculations incorporate the use of both full-load and part-load efficiency values. For ER, the actual age of the baseline system should be determined from the equipment nameplate or other physical documentation whenever possible. In the event that the actual age of the unit is unknown, default values are provided.Applicable efficient measure types include:Compressor Types: Centrifugal or Positive-displacement (Screw, Scroll, or Reciprocating)Condenser/Heat Rejection Type: Air-cooled or Water-cooled System Type Conversions. Retrofits involving a change from a chiller-based system to a packaged/split system are also covered under this measure. In the event that this type of retrofit is performed, the tables from the Split/Single Packaged Air Conditioners and Heat Pumps measure will need to be referenced.Chiller Type Conversions: Conversion from an air-cooled chiller system to a water-cooled chiller system is also addressed in this measure. An additional adjustment is made to the basic chiller savings to account for the auxiliary equipment associated with a water-cooled chiller.Eligibility CriteriaFor a measure to be eligible for this deemed savings approach the following conditions must be met:The existing and proposed cooling equipment are electric.The climate zone is determined from the county-to-climate-zone mapping table. The building falls into one of the categories listed in Table 2-32 through Table 2-36. Building type descriptions and examples are provided in Table 2-16 and Table 2-17.For early retirement projects: ER projects involve the replacement of a working system that is at least five years old before natural burnout. Additionally, the ER approach cannot be used for projects involving a renovation where a major structural change or internal space remodel has occurred. An ROB approach should be used for these scenarios.In the event that one of these conditions are not met, the deemed savings approach cannot be used, and the Simplified M&V Methodology or the Full M&V Methodology must be used.Baseline ConditionEarly RetirementEarly retirement systems involve the replacement of a working system prior to natural burnout. The early retirement baseline cannot be used for projects involving a renovation where a major structural change or internal space remodel has occurred.Two baseline condition efficiency values are required for an ER scenario, one for the ER (RUL) period and one for the ROB (EUL-RUL) period. For the ROB period, the baseline efficiency is the same as for an ROB/NC scenario. For the ER period, the baseline efficiency should be estimated using the values from REF _Ref410917286 \h \* MERGEFORMAT Table 225 through REF _Ref410915279 \h Table 230 according to the capacity, chiller type, and age (based on year of manufacture) of the replaced system. When the chiller age can be determined (from a nameplate, building prints, equipment inventory list, etc.), the baseline efficiency levels provided in REF _Ref410917286 \h Table 225 through REF _Ref410915279 Table 230 should be used. These tables will be updated every few years so that systems greater than 5 years old will be eligible for early retirement. When the system age is unknown, assume 21 years for Non-Centrifugal chillers and 26 years for Centrifugal chillers. ER baseline efficiency values represent the code-specified efficiency in effect at the time the chiller was installed. Prior to 2002, code-specified efficiencies from ASHRAE 90.1-1989 were in effect. Code-specified efficiencies increased in 2002, approximating the effective date of ASHRAE 90.1-1999, which went into effect on October 29, 2001. Code-specified efficiencies increased again in 2010, coinciding with the ASHRAE90.1-2010 code increase (Path A).Code-specified efficiencies in effect prior to 2010 (ASHRAE 90.1-2010), efficiencies were given in COP and have been converted to EER and kW/ton in the tables below using EER = COP x 3.412 and kW/ton = 3.516 ÷ COP. Values in the “< 2001” and “2002-2009” rows of REF _Ref410917286 \h \* MERGEFORMAT Table 225, REF _Ref409176978 \h \* MERGEFORMAT Table 227, REF _Ref409176985 \h \* MERGEFORMAT Table 229 have been converted and are expressed in italics.PUCT Docket 40885 provided baseline efficiencies for chillers replaced via early retirement programs, and included a category for 1990-2001. However, common practice for energy efficiency programs in Texas is to allow systems older than 1990 to use the same baseline efficiencies as those listed for 1990-2001. This practice is reflected in the baseline efficiency tables, by showing the Year Installed as ≤ 2001 rather than 1990-2001.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 25: ER Baseline Full-Load Efficiency of All Air-Cooled ChillersYear Installed(Replaced System)< 75 tons[EER]≥ 75 to 150tons[EER]≥ 150 to 300tons[EER]≥ 300 to 600tons[EER]≥ 600 tons[EER]≤ 20019.2129.2128.5308.5308.5302002 - 20099.5549.5549.5549.5549.5542010 - 20119.5629.5629.5629.5629.562Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 26: ER Baseline Part-Load Efficiency of All Air-Cooled ChillersYear Installed(Replaced System)< 75 tons[IPLV]≥ 75 to 150tons[IPLV]≥ 150 to 300tons[IPLV]≥ 300 to 600tons[IPLV]≥ 600 tons[IPLV]≤ 20019.5549.5548.5308.5308.5302002 - 200910.40710.40710.40710.40710.4072010 - 201112.75012.75012.75012.75012.750ER Baseline: Centrifugal Water-Cooled ChillersTable STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 27: ER Baseline Full-Load Efficiency of Centrifugal Water-Cooled ChillersYear Installed(Replaced System)< 75 tons[kW/ton]≥ 75 to 150tons[kW/ton]≥ 150 to 300tons[kW/ton]≥ 300 to 600tons[kW/ton]≥ 600 tons[kW/ton]≤ 20010.9250.9250.8370.7480.7482002 - 20090.7030.7030.6340.5760.5762010 - 20110.6340.6340.6340.5760.570Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 28: ER Baseline Part-Load Efficiency of Centrifugal Water-Cooled ChillersYear Installed(Replaced System)< 75 tons[IPLV]≥ 75 to 150tons[IPLV]≥ 150 to 300tons[IPLV]≥ 300 to 600tons[IPLV]≥ 600 tons[IPLV]≤ 20010.9020.9020.7810.7330.7332002 - 20090.6700.6700.5960.5490.5492010 - 20110.5960.5960.5960.5490.539ER Baseline: Positive-Displacement Water-Cooled ChillersTable STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 29: ER Baseline Full-Load Efficiency of Screw/Scroll/Recip.

Therefore, when an air-cooled chiller is replaced with a water-cooled chiller, the savings must be reduced to account for the impact of the water-cooled system’s additional equipment. This type of retrofit is only applicable for ER situations.

However, ER projects require a weighted savings calculated over both the early retirement period and the replace-on-burnout period, and take into account the EUL and the RUL. The final reported savings for ER projects are not actually a “first-year” savings, but an “average annual savings over the lifetime (EUL) of the measure”. These savings calculations are explained in Appendix D. REF _Ref410917229 \h Table 232 through Table 2-36 present the demand and energy coefficients. These HVAC coefficients vary by climate zone, building type, and equipment type. A description of the calculation method can be found in Docket No. 40885, Attachment BClaimed Peak Demand SavingsA summer peak period value is used for this measure. Refer to Volume 1, Appendix B: Peak Demand Reduction Documentation for further details on peak demand savings and methodology.Deemed Energy and Demand Savings TablesDeemed peak demand coincidence factor (CF) and equivalent full-load hour (EFLH) values are presented building type and climate zone for chillers in REF _Ref410917229 \h \* MERGEFORMAT Table 232 through Table 2-36. These tables also include an “Other” building type, which can be used for business types that are not explicitly listed. The CF and EFLH values used for Other are the most conservative values from the explicitly listed building types.? When the Other building type is used, a description of the actual building type, the primary business activity, the business operating hours, and the HVAC schedule must be collected for the project site, and stored in the utility tracking data system. For those combinations of technology, climate zone, and building type where no values are present, a project with that specific combination cannot used the deemed approach.

Packaged Terminal Air Conditioners, Heat Pumps and Room Air Conditioners Measure OverviewTRM Measure ID: NR-HV-PTMarket Sector: CommercialMeasure Category: HVACApplicable Building Types: Large Hotel and Small Hotel/MotelFuels Affected: Electricity Decision/Action Type: Replace-on-Burnout (ROB), Early Retirement (ER), and New Construction (NC)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings CalculationsSavings Methodology: CalculatorMeasure DescriptionThis section presents the deemed savings methodology for the installation of Packaged Terminal Air Conditioners (PTAC), Packaged Terminal Heat Pumps (PTHP), and Room AC (RAC) systems. This document covers assumptions made for baseline equipment efficiencies for early retirement (ER) of PTAC/PTHPs, replace-on-burnout (ROB), and new construction (NC) situations based current and previous on efficiency standards. For ER, the actual age of the baseline system should be determined from the equipment nameplate or other physical documentation whenever possible. In the event that the actual age of the unit is unknown, default values are provided. Applicable efficient measure types include:Packaged Terminal Air Conditioners and Heat Pumps. Both Standard and Non-Standard size equipment types are covered. Standard Size refers to equipment with wall sleeve dimensions having an external wall opening greater than, equal to 16 inches high or greater than, or equal to 42 inches wide and a cross sectional area greater than 670 in2. Non-Standard Size refers to equipment with existing wall sleeve dimensions having an external wall opening of less than 16 inches high or less than 42 inches wide and a cross sectional area less than 670 in2.Room Air Conditioners. Includes all equipment configurations covered by the federal appliance standards, including with or without reverse cycle, louvered or non-louvered sides, casement-only, and casement-slide.Eligibility CriteriaFor a measure to be eligible for this deemed savings approach the following conditions will be met:The existing and proposed cooling equipment are electric.The climate zone is determined from the county-to-climate-zone mapping table. For PTAC/PTHP and RAC equipment types, the eligible building types are “Large Hotel” and “Small Hotel/Motel. Building type descriptions and examples are provided in REF _Ref428187133 \h \* MERGEFORMAT Table 216 and REF _Ref433116522 Table 217.For early retirement PTAC/PTHP projects: ER projects involve the replacement of a working system that is at least five years old before natural burnout. Additionally, the ER approach cannot be used for projects involving a renovation where a major structural change or internal space remodel has occurred. An ROB approach should be used for these scenariosIn the event that one of these conditions are not met, the deemed savings approach cannot be used, and the Simplified M&V Methodology or the Full M&V Methodology must be used.Baseline ConditionEarly Retirement for PTAC/PTHP SystemsAn early retirement scenario is only applicable for Standard Size PTAC/PTHP system types replacing system types with an equivalent cooling capacity or reduced cooling capacity (within 80% of existing capacity).Two baseline condition efficiency values are required for an ER scenario, one for the ER (RUL) period and one for the ROB (EUL-RUL) period. For the ROB period, the baseline efficiency is that same as for an ROB/NC scenario. For the ER period, the baseline efficiency should be estimated according to the capacity, system type (PTAC or PTHP), and age (based on year of manufacture) of the replaced system. When the system age can be determined (from a nameplate, building prints, equipment inventory list, etc.), the baseline efficiency levels provided in REF _Ref410917635 \h Table 239, reflecting ASHRAE Standard 90.1-2001 through 90.1-2007, should be used. When the system age is unknown, assume 17 years.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 39: ER Baseline Efficiency Levels for Standard Size PTAC/PTHP UnitsEquipmentCoolingCapacity[Btuh]Baseline CoolingEfficiency [EER]Baseline HeatingEfficiency [COP]PTAC<7,00011.0--7,000-15,00012.5-0.213×Cap/1000-->15,0009.3--PTHP<7,00010.83.07,000-15,00012.3-0.213×Cap/10003.2-0.026×Cap/1000>15,0009.12.8Replace-on-Burnout and New Construction REF _Ref381691914 \h Table 240 provides minimum efficiency standards for PTAC/PTHP units and reflects the federal standards for Packaged Terminal Air Conditioners and Heat Pumps effective February 2013 and reflected in 10 CFR 431.

The first year savings algorithms in the above equations are used for all HVAC projects, across NC, ROB, and ER projects. However, ER projects require a weighted savings calculated over both the ER and ROB periods taking the EUL and RUL into account. The ER savings are applied over the remaining useful life (RUL) period, and the ROB savings are applied over the remaining period (EUL-RUL). The final reported savings for ER projects are not actually a “first-year” savings, but an “average annual savings over the lifetime (EUL) of the measure”. These savings calculations are explained in Appendix D.Claimed Peak Demand SavingsA summer peak period value is used for this measure. Refer to Volume 1, Appendix B: Peak Demand Reduction Documentation for further details on peak demand savings and methodology.Deemed Energy and Demand Savings TablesTable 2 42 and Table 2 43 present the coincident factor (CF) and equivalent full-load hour (EFLH) values for PTAC/PTHPs and RACs. These values are calculated by climate zone, building type, and equipment type.

HVAC Variable Frequency Drive (VFD) on Air Handler Unit (AHU) Supply Fans Measure OverviewTRM Measure ID: NR-HV-VFMarket Sector: CommercialMeasure Category: HVACApplicable Building Types: See REF _Ref366837591 \h \* MERGEFORMAT Table 247 though REF _Ref410917982 \h Table 249Fuels Affected: Electricity Decision/Action Type: Retrofit (RET)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings ValuesSavings Methodology: Look-up Tables (fan type, motor hp, Climate Zone, Building Type)Measure DescriptionThis measure involves the installation of a VFD on an existing AHU supply fan to replace either outlet damper or inlet guide vane part-load control. The fan is in a variable air volume (VAV) system with terminal VAV boxes. This measure accounts for the interactive air-conditioning demand savings during the utility defined summer peak period. The savings are on a per-control basis and the lookup tables show the total savings for particular eligible scenarios. Eligibility CriteriaSupply fans may not have variable pitch blades. New construction and constant-volume systems are ineligible. Supply fans must be less than or equal to 100 HP.Baseline ConditionThe 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 standards which are provided by horsepower. The AC unit has standard cooling efficiency based on ASHRAE 90.1-2004. The part-load fan control is an outlet damper, inlet damper or inlet guide vane. High-Efficiency ConditionThe high efficiency condition is 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 delivering the same amount of air as the baseline condition.Energy and Demand Savings MethodologySavings Algorithms and

Roofs Measure OverviewTRM Measure ID: NR-BE-CR Market Sector: CommercialMeasure Category: Building EnvelopeApplicable Building Types: Specific building types defined by each utilityFuels Affected: Electricity Decision/Action Type: Retrofit (RET)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings CalculationSavings Methodology: Calculators, WorksheetsMeasure DescriptionThis section presents the deemed savings methodology for the installation of an ENERGY STAR? certified roof. The installation of an ENERGY STAR? roof decreases the roofing heat transfer coefficient and reduces the solar heat transmitted to the building space. During months when cooling is required in the building, this measure decreases the cooling energy use.Eligibility CriteriaThe simplified M&V guidelines are applicable for roofs with a slope of 2.5 or less only. Reflectivity must be at least 65% at three years, have at least a 10-year life, and be listed on the ENERGY STAR? list of qualified products.Baseline Condition A baseline is not specified in the program manuals for any of the utilities. The only utility to specify baseline requirements is EPE, in PUCT Docket No. 41070, which states that the baseline is considered to be a black ethylene propylene diene monomer (EPDM) roofing membrane with a solar reflectance of 6.2%. The building is assumed to have a ceiling with a total R-value (including construction materials) of 18. Electric AC was assumed to have an EER of 8.5, and electric heating, a COP of 1.High-Efficiency ConditionA high efficiency condition is not specified in the program manuals for any of the utilities. The only utility to specify high efficiency requirements is EPE, in PUCT Docket No. 41070 in which it was determined that to qualify for a cool roof at least 75% of the roof surface over conditioned space must be replaced by a material with a solar reflectance of at least 70%. The roof must also receive significant direct sunlight.Energy and Demand Savings MethodologySavings Algorithms and Input VariablesAcross the Texas utilities, there are several ways of calculating energy and demand savings for ENERGY STAR? roofs. Oncor and AEP use the algorithms below in their calculators to calculate their savings.

Window Treatments Measure OverviewTRM Measure ID: NR-BE-WFMarket Sector: CommercialMeasure Category: Building EnvelopeApplicable Building Types: All Commercial Building Types Fuels Affected: Electricity Decision/Action Type: Retrofit (RET)Program Delivery Type: PrescriptiveDeemed Savings Type: Deemed Savings CalculationsSavings Methodology: AlgorithmsMeasure DescriptionThis section presents the deemed savings methodology for the installation of window films and solar screens. The installation of window film 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. Demand and energy savings result in demand and energy use of cooling equipment. Eligibility CriteriaThis measure is applicable for treatment of single-paned windows in south or west facing orientations (as specified in Table 2-56 that do not have existing solar films or solar screens, are not shaded by exterior awnings, curtains, or overhangs, in buildings that are mechanically cooled (DX or chilled water). Baseline ConditionThe baseline condition is single-pane clear glass, without existing window treatment. Interior and exterior shading is acceptable, but should be considered in the savings calculation. High-Efficiency ConditionThe high-efficiency condition is an eligible window treatment applied to eligible windows. Energy and Demand Savings MethodologyThe demand and energy savings equations in this section originated in calculations by the EUMMOT utilities as presented in the EUMMOT program manual Commercial Standard Offer Program: Measurement and Verification Guidelines for Retrofit and New Construction Projects. The method estimates reduction in solar heat gain/insolation attributable to a given window treatment using shading coefficients for the treated and untreated window and solar heat gain estimates by window orientation according to ASHRAE Fundamentals. The reduction in building energy use attributable to reduction in cooling system energy use is estimated based on the reduced heat removal requirement for a standard efficiency cooling system.Savings Algorithms and Input VariablesDemand Savingso kW=Afilm,o×SHGFo×SCpre, o-SCpost,o3413×COPEquation SEQ Equation \* ARABIC 46Peak Demand Savings kW=DemandSavingo, maxEquation SEQ Equation \* ARABIC 47Energy Savingso kWh= Afilm,o×SHGo×SCpre, o-SCpost,o3413×COPEquation SEQ Equation \* ARABIC 48Energy Savings kWh= Energy SavingsoEquation SEQ Equation \* ARABIC 49Where:Demand Savings =Peak demand savings per window orientationEnergy Savings=Energy savings per window orientationAfilm,o=Area of window film applied to orientation [ft2]SHGFo=Peak solar heat gain factor for orientation of interest [Btu/hr-ft2-year].

Convection ovens cook their food by forcing hot dry air over the surface of the food product. The rapidly moving hot air strips away the layer of cooler air next to the food and enables the food to absorb the heat energy. The energy and demand savings are deemed, and based off of energy rates of the oven, cooking efficiencies, operating hours, production capacities and building type. An average energy and demand consumption has been calculated based on these default values to create a stipulated savings value. The energy and demand savings are determined on a per-oven basis. Eligibility CriteriaEligible units must meet ENERGY STAR? qualifications, with half-size and full-size electric ovens as defined by ENERGY STAR?. Half-Size Combination Oven: A combination oven capable of accommodating half-size sheet pans measuring 18 x 13 x 1-inch.Full-Size Combination Oven: A combination oven capable of accommodating standard full-size sheet pans measuring 18 x 26 x 1-inch.Eligible building types include independent restaurants, chain restaurants, elementary and secondary schools, colleges and universities, corporate foodservice operations, healthcare, hospitality, and supermarkets.Convection ovens eligible for rebate do not include ovens that have the ability to heat the cooking cavity with saturated or superheated steam.Baseline ConditionEligible baseline condition for retrofit situations is an electric convection oven.

Commercial dishwashers that have earned the ENERGY STAR? label are on average 25% more energy-efficient and 25% more water-efficient than standard models. The energy savings associated with ENERGY STAR? commercial dishwashers is primarily due to reduced water use and reduced need to heat water. A commercial kitchen may have external booster water heaters or booster water heaters may be internal to specific equipment. Both primary and booster water heaters may be either gas or electric; therefore, dishwasher programs need to assure the savings calculations used are appropriate for the water heating equipment installed at the participating customer’s facility. The energy and demand savings are determined on a per-dishwasher basis. Eligibility CriteriaThe dishwasher must be ENERGY STAR? certified and fall under one of the following categories, and are described in REF _Ref367189638 \h \* MERGEFORMAT Table 268:Under Counter DishwasherStationary Rack, Single Tank, Door Type DishwasherSingle Tank Conveyor DishwasherMultiple Tank Conveyor DishwasherPot, Pan & UtensilEligible building types include independent restaurants, chain restaurants, elementary and secondary schools, colleges and universities, corporate foodservice operations, healthcare, hospitality, and supermarkets.Dishwashers intended for use in residential or laboratory applications are not eligible for ENERGY STAR? under this product specification.

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.Eligibility CriteriaN/ABaseline ConditionBaseline efficiency case is a cooler or a freezer door heater that operates 8,760 hours per year without any controls.High-Efficiency Condition 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. Energy and Demand Savings MethodologySavings Algorithms and Input Variables The energy savings from the installation of Anti-Sweat heater controls are a result from both the decrease in length of time the heater is running (kWhASH) and the reduction in load on the refrigeration (kWhrefrig). These savings are calculated using the following procedures:Indoor dew point (td-in) can be calculated from outdoor dew point (td-out) using the following equation:td-in=0.005×td-out2+0.172×td-out+19.870Equation SEQ Equation \* ARABIC 75The baseline assumes door heats are running on 8,760 operation. In the post-retrofit case, the duty for each hourly reading is calculated by assuming a linear relationship between indoor DP and duty cycle for each bin reading. It is assumed that the door heaters will be all off (duty cycle of 0%) at 42.89?F DP and all on (duty cycle of 100%) at 52.87?F for a typical supermarket. Between these values, the door heaters’ duty cycle changes proportionally:Door Heater ON%= td-in-All OFF setpt 42.89°FAll ON setpt 52.87℉-All OFF setpt 42.89°FEquation SEQ Equation \* ARABIC 76The controller only changes the run-time of the heaters so the instantaneous door heater power (kWASH) as a resistive load remains constant per linear foot of door heater at:kWASH=115V×0.37Aft1000×Linear ft of door heater=0.043kWft×ft of door heaterEquation SEQ Equation \* ARABIC 77Door heater energy consumption for each hour of the year is a product of power and run-time:kWhASH-Hourly=kWASH×Door Heater ON% ×1HourEquation SEQ Equation \* ARABIC 78kWhASH= kWhASH-HourlyEquation SEQ Equation \* ARABIC 79To calculate energy savings from the reduced refrigeration load using average system efficiency and assuming that 35% of the anti-sweat heat becomes a load on the refrigeration system, the cooling load contribution from door heaters can be given by:QASHton-hrs=0.35×kWASH×3413Btuhr12000Btuton×Door Heater ON%Equation SEQ Equation \* ARABIC 80The compressor power requirements are based on calculated cooling load and energy-efficiency ratios obtained from manufacturers' data. The compressor analysis is limited to the cooling load imposed by the door heaters, not the total cooling load of the refrigeration system. For medium temperature refrigerated cases, the saturated condensing temperature (SCT) is calculated as the design dry-bulb temperature plus 15 degrees. For low temperature refrigerated cases, the SCT is the design dry-bulb temperature plus 10 degrees. The EER for both medium- and low-temperature applications is a function of SCT and part load ratio (PLR) of the compressor. PLR is the ratio of total cooling load to compressor capacity, and is assumed to be a constant 0.87.For medium temperature compressors, the following equation is used to determine the EERMT [Btu/hr/watts]. These values are shown in Table 2-88.EERMT=a+b×SCT+c×PLR+d×SCT2+e×PLR2+f×SCT×PLR+g×SCT3+h×PLR3+i×SCT×PLR2+j×SCT2×PLREquation SEQ Equation \* ARABIC 81Where:a=3.753b=-0.050c=29.459d=0.0003e =-11.771f =-0.213g=-1.466 x 10-6h=6.802I=-0.020j=0.0007PLR=0.87SCT=ambient design temperature+ 15For low temperature compressors, the following equation is used to determine the EERLT [Btu/hr/watts]:EERLT=a+b×SCT+c×PLR+d×SCT2+e×PLR2+f×SCT×PLR+g×SCT3+h×PLR3+i×SCT×PLR2+j×SCT2×PLREquation SEQ Equation \* ARABIC 82Where:a=9.867b=-0.230c =22.906d=0.002e=-2.489f=-0.248g=-7.575 x 10-6h=2.036i=-0.021j=0.0009PLR=0.87SCT=ambient design temperature+10Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 88: Values Based on Climate Zone CityClimate ZoneSummer Design Dry Bulb TempSCTMTSCTLTEERMTEERLTAmarillo961111066.444.98Dallas-Ft.

It is recommended that these film-type covers have small, perforated holes to decrease the build-up of moisture.Eligibility CriteriaAny suitable material sold as a night cover. BaselineBaseline efficiency case is an open low-temperature or medium-temperature refrigerated display case (vertical or horizontal) that is not equipped with a night cover. High-Efficiency ConditionEligible 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.Energy and Demand Savings MethodologySavings Algorithms and Input VariablesThe following outlines the assumptions and approach used to estimate demand and energy savings due to installation of night covers on open low- and medium-temperature, vertical and horizontal, display cases. Heat transfer components of the display case include infiltration (convection), transmission (conduction), and radiation. This work paper assumes that installing night covers on open display cases will only reduce the infiltration load on the case. Infiltration affects cooling load in the following ways:Infiltration accounts for approximately 80% of the total cooling load of open vertical (or multi-deck) display cases.Infiltration accounts for approximately 24% of the total cooling load of open horizontal (coffin or tub style) display cases. NOTEREF _Ref364341003 \f \h 150Installing night covers for a period of 6 hours per night can reduce the cooling load due to infiltration by:8% on vertical cases NOTEREF _Ref364341003 \f \h 15050% on horizontal casesThe energy savings due to the reduced infiltration load when night covers are installed will vary based on outdoor temperature and climate zone. As a result the energy savings must be determined for each climate zone and typical outdoor temperatures when the covers are applied.Once the infiltration load for each type of case was determined, the following steps were followed to determine the compressor power requirements and energy savings. It is important to reiterate that heat transfer in display cases occurs due to convection, conduction, and radiation. The analysis presented here is limited to the cooling load imposed by convection (infiltration) only and not the total cooling load of a particulate display case.In the base case it is assumed that no night covers are installed on the cases and the infiltration cooling load for each bin can be given by:QbaselineInfiltrationton-hours=QbaselineInfiltrationBtuh×Bin-hours12,000 BtutonEquation SEQ Equation \* ARABIC 98The compressor power requirements are based on calculated cooling load and energy-efficiency ratios (EER) obtained from manufacturers’ data.Determine the saturated condensing temperature (SCT)For Medium Temperature (MT): SCT=DBadj+15Equation SEQ Equation \* ARABIC 99For Low Temperature (LT): SCT=DBadj+10Equation SEQ Equation \* ARABIC 100Where:DBadj=Design dry-bulb temperature (?F), based on climate zone, of ambient or space where the compressor/condensing units reside.

It indicates the percentage of compressor capacity needed to remove the total cooling load. It is calculated by the following equation:PLR=QcoolingQcapacityEquation SEQ Equation \* ARABIC 101Where:PLR=Part Load RatioQcooling =Cooling LoadQcapacity=Total Compressor CapacityQcapacity=Qcooling×1.15PLR=11.15=0.87To simplify the analysis, it is assumed that PLR remains constant for the post-retrofit condition. The energy efficiency ratio (EER) is a measure of how efficient a cooling system operates at a particular temperature. It is defined as the ratio of useful energy transfer to the work input. For refrigeration systems it is the ratio of heat removed by the compressor (Btu/h) to the input power (Watts). The higher the EER the greater the efficiency of the system.For medium temperature compressors, the following equation is used to determine the EERMT (Btu/hr/watts). The equation uses SCT (from step 2), and a PLR of 0.87 (from step 3b).EERMT=a+b×SCT+c×PLR+d×SCT2+ e×PLR2+f×SCT×PLR+g×SCT3+h×PLR3+i×SCT×PLR2+j×SCT2×PLREquation SEQ Equation \* ARABIC 102Where:a=3.753b =-0.050c = 29.459d= 0.0003e= -11.771f= -0.213g= -1.466 x 10-6h= 6.802i= -0.020j= 0.0007For low temperature compressors, the following equation is used to determine the EERLT (Btu/hr/watts).

Hotel and motel guest room occupancy schedules are highly variable, and guests often leave HVAC equipment and lighting on when they leave the room. Installation of occupancy controls can reduce the unnecessary energy consumption in unoccupied guest rooms. Savings have also been developed for use of this measure in college dormitories. This measure is also commonly referred to as a guest room energy management (GREM) system.Eligibility CriteriaTo be eligible for HVAC savings, controls must be capable of either a 5?F or 10?F temperature offset. To be eligible for lighting savings, at least 50% of all the lighting fixtures in a guest room – both hardwired and plug-load lighting - must be actively controlled. Baseline ConditionThe baseline condition is a guest room or dorm room without occupancy controls.High-Efficiency ConditionThe high-efficiency condition is a hotel/motel guest room or dorm room with occupancy controls. The occupancy sensors can control either the HVAC equipment only, or the HVAC equipment and the interior lighting (including plug-in lighting). The occupancy-based control system must include, but not be limited to, infrared sensors, ultrasonic sensors, door magnetic strip sensors, and/or card-key sensors. The controls must be able to either completely shut-off the HVAC equipment serving the space and/or place it into an unoccupied temperature setback/setup mode.Energy and Demand Savings MethodologyEnergy and demand savings are deemed values based on energy simulation runs performed using EnergyPro Version 5. Building prototype models were developed for a hotel, motel, and dormitory. The base case for each prototype model assumed a uniform temperature setting, and was calibrated to a baseline energy use. Occupancy patterns based on both documented field studies and prototypical ASHRAE 90.1-1999 occupancy schedules were used in the energy simulation runs to create realistic vacancy schedules. The prototype models were then adjusted to simulate an occupancy control system, which was compared to the baseline models. Savings Algorithms and InputsA building simulation approach was used to produce savings estimates.Deemed Energy and Demand Savings TablesEnergy and demand savings are provided by region, for HVAC-Only and HVAC+Lighting control configurations, and for three facility types: Motel and Hotel guest rooms, and Dormitory rooms.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 110: Deemed Energy and Demand Savings for Motel per Guest Room, by RegionRepresentative City (Region)Heat PumpElectric HeatHVAC-OnlyHVAC & LightingHVAC-OnlyHVAC & LightingkWkWhkWkWhkWkWhkWkWh5-Degree Setup/Setback OffsetAmarillo (Panhandle)0.0592670.0753800.0593410.075441Dallas-Ft Worth (North)0.0763150.0914430.0763650.091485Houston (South)0.0823240.0974610.0823510.097484McAllen (Valley)0.0863540.1035000.0863690.103513El Paso (West)0.0632510.0783790.0632830.07840610-Degree Setup/Setback OffsetAmarillo (Panhandle)0.1114860.1265980.1116270.126726Dallas-Ft Worth (North)0.1465590.1616860.1466400.161761Houston (South)0.1515590.1666950.1516020.166735McAllen (Valley)0.1636170.1797610.1636500.179792El Paso (West)0.1184320.1335610.1184820.133607Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 111: Deemed Energy and Demand Savings for Hotel per Guest Room, by RegionRepresentative City (Region)Heat PumpElectric HeatHVAC-OnlyHVAC & LightingHVAC-OnlyHVAC & LightingkWkWhkWkWhkWkWhkWkWh5-Degree Setup/Setback OffsetAmarillo (Panhandle)0.0532320.0724390.0533030.072530Dallas-Ft Worth (North)0.0732580.0934520.0733030.093505Houston (South)0.0742420.0944300.0742600.094450McAllen (Valley)0.0812600.1024510.0812670.102459El Paso (West)0.0561780.0753600.0561960.07538010-Degree Setup/Setback OffsetAmarillo (Panhandle)0.1024260.1215680.1025570.121684Dallas-Ft Worth (North)0.1344520.1546170.1345170.154676Houston (South)0.1364230.1565990.1364460.156621McAllen (Valley)0.1494670.1696520.1494830.169667El Paso (West)0.1063120.1264790.1063380.126501Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 112: Deemed Energy and Demand Savings for Dormitories per Room, by RegionRepresentative City (Region)Heat PumpElectric HeatHVAC-OnlyHVAC & LightingHVAC-OnlyHVAC & LightingkWkWhkWkWhkWkwhkWkWh5-Degree Setup/Setback OffsetAmarillo (Panhandle)0.0341360.0613190.0341520.061316Dallas-Ft Worth (North)0.0482140.0764250.0482230.076428Houston (South)0.0512420.0784610.0512440.078462McAllen (Valley)0.0532650.0814920.0532660.081492El Paso (West)0.0311100.0593270.0311100.05932610-Degree Setup/Setback OffsetAmarillo (Panhandle)0.0732610.0844040.0732890.084417Dallas-Ft Worth (North)0.0782930.1055050.0783040.105511Houston (South)0.0813260.1085430.0813280.108545McAllen (Valley)0.0883680.1145910.0883700.114593El Paso (West)0.0451510.0604480.0451530.060450Claimed Peak Demand Savings Refer to Volume 1, Appendix B: Peak Demand Reduction Documentation for further details on peak demand savings and methodology.Measure Life and Lifetime SavingsEstimated Useful Life is 10 years based on the value for retrofit energy management system (EMS) HVAC control from the Massachusetts Joint Utility Measure Life Study.

These controllers are used to shut down the pump when the fluid falls below a certain level and “fluid pounding” occurs. POCs save energy by optimizing the pump run-times to match the flow conditions of the well.Eligibility CriteriaThe POC measure retrofit is available for existing wells (wells with an existing API number prior to September 11th, 2014) with rod pumps using 15 hp or larger motors operating on time clock controls or less efficient devices. These cannot be integrated with a variable frequency drive, and only apply to POCs using load cells, which measure the weight on the rod string for greater precision. Additionally, the POC must control a conventional well (above ground, vertical, with a standard induction motor of 480V or less). Baseline ConditionThe baseline condition is an existing conventional well (with an API number prior to September 11th, 2014) with rod pumps operating on time clock controls or less efficient control devices.High-Efficiency ConditionThe efficient condition is the same existing well retrofitted with a pump-off controller. Energy and Demand Savings MethodologyTwo main sources were referenced to develop the savings methods for the POC measure: Electrical Savings in Oil Production (SPE 16363), which identified a relationship between volumetric efficiency and pump run times, and the 2006-2008 Evaluation Report for PG&E Fabrication, Process, and Manufacturing Contract Group, which showed a reduction in savings from the SPE 16363 paper. These two methods were the basis of the current savings calculations and deemed inputs listed below. However, to develop Texas-specific stipulated values, field and metering data will be collected in 2015 and used to calibrate and update the savings calculation methods and input variables for a future version of the TRM.Savings Algorithms and InputsThe energy and demand algorithms and associated input variables are listed below:Energy Savings kWh=kWavg*TimeClock%On-POC%On*8760Equation SEQ Equation \* ARABIC 113Demand Savings kW=EnergySavings8760Equation SEQ Equation \* ARABIC 114The inputs for the energy and peak coincident demand savings are listed below: kWavg=HP×0.746×LFMESMEEquation SEQ Equation \* ARABIC 115POC%On=RunConstant+RunCoefficient×VolumetricEfficiency%×TimeClock%On×100100Equation SEQ Equation \* ARABIC 116Where:kWavg=The demand used by each rod pumpHP =Rated pump motor horsepower0.746=Conversion factor from HP to kWLF = Motor load factor – ratio of average demand to maximum demand, see Table 2-114 ME=Motor efficiency, based on NEMA Standard Efficiency Motor, see Table 2-115SME=Mechanical efficiency of sucker rod pump, see Table 2-114TimeClock%On=Stipulated baseline timeclock setting, see Table 2-114Runconstant, Runcoefficient=8.336, 0.956.

These programs are offered by the Texas utilities, with the primary objective to achieve cost-effective energy savings and peak demand savings. Participation in the Solar Photovoltaic program involves the installation of a solar photovoltaic system. There are two primary methods used to estimate savings. The deemed method uses deemed algorithms, and the M&V method uses a simulation tool: the National Renewable Energy Laboratory’s (NREL) PVWatts?. Each utility has a minimum and maximum incentivized system size, as shown in REF _Ref366143749 \h Table 2117, as well as additional eligibility criteria.Table STYLEREF 1 \s 2 SEQ Table \* ARABIC \s 1 117: Incentivized System Ranges by UtilityUtilityMinimum Incentivized Size [kW]Maximum Incentivized Size [kW]Oncor1 kWN/AAEP (all entities)1 kW25 kWEl Paso Electric (EPE)1 kW10 kWEligibility CriteriaA project will be eligible for rebates under the Solar Photovoltaic programs if the following criteria are met:Eligible equipment must be new, and used for individually metered commercial buildings. Used, refurbished, and existing solar PV systems are not eligible for incentives.System ranges must be met, as described above in Table 2-117.Solar electric systems must deliver energy to a building’s electrical distribution system which is connected to the utility. Portable systems, systems of a temporary nature, and off-grid systems are ineligible.Each utility may have additional program eligibility requirements, which are listed here. These requirements are provided for reference purposes only, and are not listed in any PUCT-approved petition. Therefore, these utility-specific eligibility requirements may be subject to change.Oncor:Electrical output of the installed solar PV system is limited to 75% of the host customer’s demand during summer peak demand. Additionally, annual energy generation should not exceed the customer’s annual energy consumption.A deemed savings approach can only be used for “standard” systems. A standard system, for both residential and nonresidential PV systems, is defined as a system that does not exceed an azimuth angle of +/- 20? of south, and has a tilt angle between 0? (horizontal) and [system latitude + 15?]. The azimuth angle requirement is irrelevant for flat panel systems. Systems that fall outside of these requirements are considered non-standard systems, and are required to use a site-specific approach for energy and demand production impacts.El Paso Electric & AEP:Modules and Inverters must be new and certified to UL 1741 standards by a Nationally Recognized Testing Laboratory (NRTL). Eligible modules must be warranted for at least 10 years to produce at least 90% of their rated power output, and for at least 20 years to produce at least 80% of their rated power output.Energy produced will be monitored by a utility-provided Revenue-Grade Solar (REC) Meter.The estimated annual electrical energy output of a solar electric system, as modeled by National Renewable Energy Laboratory’s (NREL) PVWatts? and considering an appropriate factor for shading, must be at least 80% of the estimated annual energy output for an optimally-sited, un-shaded system of the same DC capacity.A deemed savings approach is used to claim savings for all eligible systems, however, no mention of this deemed savings approach is found in any of the EPE or AEP program manuals. The deemed savings approach used is the same as is used by Oncor, and listed below in the section on REF _Ref372881679 \h \* MERGEFORMAT Savings Algorithms and Input Variables. The EPE and AEP program manuals actually discuss the method of savings calculations as an M&V Methodology, however, project desk reviews performed for the 2012 evaluations did not find any of these M&V methods being used. The M&V methodology, which is currently being used by Oncor for non-standard installations, is listed below in the section titled, REF _Ref372881893 \h \* MERGEFORMAT M&V Methodology.Baseline Condition PV system not currently installed (typical), or production capacity of an existing system is less than any utility requirements, so that additional panels can be added.High-Efficiency ConditionPV systems must meet the eligibility criteria shown above to be eligible for incentives. Energy and Demand Savings Methodology Savings Algorithms and Input Variables The deemed energy and demand savings methodology is used by all utilities. An alternate approach for ‘non-standard’ installations is also available state-wide.Energy and demand savings methodology for standard installations use a deemed algorithm based on the system size.

See the section labeled REF _Ref366155261 \h \* MERGEFORMAT Program Tracking Data & Evaluation Requirements below to see the additional information needing to be collected.M&V MethodologyThe estimated annual electrical energy output of the proposed system shall be derived from PVWatts? and shall consider separately the effects of tilt, orientation and shading on each array and/or string, as appropriate. The effect of shading shall be determined using a Solar Pathfinder or equivalent instrument. As a general rule, multiple shading measurements should be made along the lower or southern edge of an array, and/or locations where shading is most prevalent. Non-Standard Installation:PUCT Docket No. 40885 allows for alternative means for estimating deemed savings for solar PV systems for non-standard installations, allowing commercial customers around the state access to utility incentives for systems installed on roofs – or portions of roofs – that are not within 20 degrees of south, or for which the tilt angle must exceed 15 degrees from horizontal due to site specific considerations. The proposed alternative would also facilitate the installation of single-axis or two-axis tracking systems. For those solar PV installations that do not conform to the installation standards of the existing deemed savings, the deemed demand and energy savings be established by modeling the performance of the system using PVWatts?

This supersedes the previous Measure Life Savings found in PUCT Dockets 40083 and 40885, and is revised to clarify the understanding of the Measure Life calculations and reduce any misrepresentation of Net Present Value (NPV) of early retirement projects. These calculations are provided in the Docket [43681].

However, the efficiency values used in estimating the equations differ from those used in Petitions 40083 and 40885: (1) the Early Retirement savings, earned for the RUL of the replaced system, are estimated using the difference between the efficiency of the replaced system and that of the installed system; (2) the replace-on-burnout savings, earned over the measure EUL minus the project’s RUL, are estimated using the difference between the replace-on-burnout baseline efficiency and the efficiency of the installed system.Step 4: Calculate the total capacity and energy cost contributions to the total NPV:NPVTotal, kW=NPVER,kW+NPVROB,kWEquation SEQ Equation \* ARABIC 129NPVTotal, kWh=NPVER,kWh+NPVROB,kWhEquation SEQ Equation \* ARABIC 130Where:NPVTotal, kW=Total capacity contributions to NPV of both ER and ROB component NPVTotal, kWh=Total energy contributions to NPV of both ER and ROB component Step 5: Calculate the capacity and energy cost contributions to the NPV without weighting by demand and energy savings for a scenario using the original EUL:NPVEUL, kW=ACkW×1+ed-e×1-1+e1+dEULEquation SEQ Equation \* ARABIC 131NPVEUL, kWh=ACkWh×1+ed-e×1-1+e1+dEULEquation SEQ Equation \* ARABIC 132Where:NPVEUL, kW=Capacity contributions to NPV without weighting, using original EULNPVTotal, kWh=Energy contributions to NPV without weighting, using original EULStep 6: Calculate the weighted demand and energy savings by dividing the combined capacity and energy cost contributions from the ER and ROB scenarios by the non-savings weighted capacity and energy cost contributions from the single EUL scenario.
