DEER error corrections DEER 2019 Suspension of below-code NTG adjustment factor The below-code NTG adjustment factor for accelerated replacement (AR) applications has been suspended, effective 2019-01-01 and lasting indefinitely.

Suspend below-code NTG adjustment factor

Per the DEER2021 DRAFT Update Scoping Memo, issued 2019-04-29, the below-code NTG adjustment factor for AR applications has been suspended, effective 2019-01-01 and lasting indefinitely. The DEER2020 Update Resolution E-4952, Section 5.4 introduced the requirement for a below-code Net-to-Gross adjustment factor for accelerated replacement measures. (See DEER2020 Update Resolution E-4952, Section 5.4 Net-to-Gross for Accelerated Replacement Measure, pages A-42 to A-47, http://docs.cpuc.ca.gov/publisheddocs/published/g000/m232/k459/232459122.pdf.) This concept was adapted from the “Energy Efficiency Potential and Goals Study for 2018 and Beyond” as a way to adjust for savings already accounted for by Codes and Standards, and potential differences for below- and above-code free-ridership. (See http://docs.cpuc.ca.gov/PublishedDocs/Efile/G000/M194/K614/194614840.PDF, Aug 23, 2017, Navigant Consulting, Inc.) The adjustment was assumed to be effective for 2019 programs, as part of the general change in Measure Application Type from Early Replacement (ER) to Accelerated Replacement (AR) that was also directed in the Resolution.

However,Energy Division Staff has asked the Program Administrators not to make this change for 2019 claims or for future reporting and filing needs. We have had multiple meetings with utility staff and we appreciate their work, but it would be difficult to make the needed structural data system changes at this time due to limited resource availability and to meet the future reporting schedule. Staff also decided that a manual, interim fix is not desirable given the complications around communicating it to third party implementers, resulting in over/underestimated savings, and uncertainty around tracking and verifying the manual updates. Finally, the portfolio impact of net-to-gross for to-code savings is not clear at this time, as not all PAs appear to have a high presence of accelerated replacement measures in their portfolios. Notice of this change was previously communicated to the PAs via email on 2019-04-16, but will be included in the DEER2021 update resolution to be issued later this year. Comments on the future viability and application of this concept were requested in response to the DRAFT DEER2021 Update Scoping Memo.

DEER2020 Update

Commission staff, with the assistance of its DEER contractor team, developed a set of revisions for DEER2019 and a DEER2020 update in compliance with D.15-10-028, D.16-08-019, and Resolution E-4818. The updates were adopted on October 11, 2018 by the Commission via Final Resolution E-4952, issued on Energy Division’s own motion pursuant to Decision D.15-10-028. A summary of each of the changes can be found in the Attachment of Resolution E-4952. Errors and clarifications for the Resolution discovered after its passage are documented in the DEER2020 Update errata document. This web page provides general information about the updates and links to more detailed documentation and supporting materials. 

The proposed update was first described in a Scoping Memo issued by Commission staff May 9, 2018. Parties submitted comments on the proposed updates per the Draft Resolution E-4952 Comment Letter. The scoping memo solicited comments from parties which were filed later in May 2018. The commission staff and its DEER contractor then provided responses to the comments in the Draft Resolution Attachment, as well as incorporated appropriate changes to the update scope as reflected in the Draft Resolution and its Attachment.

Some minor typos, broken links and missing file references for the Draft Resolution E-4952 were identified and corrected in an Update to the Attachment. A public webinar for Draft Resolution E-4952 covering the DEER2020 updates and DEER2019 revisions was held September 10, 2018. Webinar slides are available here: PowerPoint Version PDF version

 

The DEER2019-2020 update included these categories of proposed changes:

  • Peak Period Definition: Peak period demand values have been updated for all measures based on the new peak period definition proposed by the working group established in response to Resolution E-4867.
  • Addition: New measures are added in response to Program Administrator requests or due to the proposal to move non-DEER workpaper measures into DEER.
  • Correction/Methodology Update: Previous measure values are changed due to errors or improvements identified in the existing DEER measure assumptions, methods or values. NOTE: An Extended-Hours Prototype was considered in the Scoping Memo, but not pursued for the final update. This new commercial building prototype would have included extended hours of operation and high load activity areas such as clean rooms, manufacturing process, or data centers, and used central chillers as the main cooling source.
  • Code Update: Measure code baselines are updated in response to adopted state or federal code changes becoming effective.
  • Evaluation Update: Measure assumptions or analysis methods are updated as a result of recent evaluation data.

LED Indoor and Outdoor Lighting

The DEER2019 update incorporates the standard practice baselines from recent dispositions covering exterior, interior low-bay, interior high-bay, screw-in and can-retrofit lighting. Measures that were previously identified in the Preliminary Ex Ante Review database (PEARdb) have been migrated to the Ex Ante database (EAdb) and identified as DEER2019 measures. In addition to incorporating measures covered by recent workpaper dispositions, DEER2019 updates the standard practice baseline for all other normal replacement (NR), new construction (NC), replace-on-burnout (ROB), and accelerated replacement (AR) measures to be based on LED technologies. This includes LED ceiling, troffer and retrofit kits measures that have previously been defined with T8 linear fluorescent baselines. Supporting documents for revised lighting measures are as follows:

DHW Rating Change

In June of 2017, federal requirements for rating of small and residential use water heaters changed from Energy Factor (EF) to Uniform Energy Factor (UEF). At the time of issuance of the DEER update Resolution E-4867 in August 2017, available product databases published by the CEC and The Air Conditioning Heating and Refrigeration Institute (AHRI) did not include sufficient quantities of UEF rated water heaters to develop typical code baseline and measure level performance criteria. For the DEER 2019 update, these databases have been reviewed to support updates to the industry standard practice baselines and measure tiers for residential 30, 40 and 50 gallon gas storage water heaters and residential tankless water heaters. Supporting documents for the DHW measures are as follows:

  • DEER2020 CEC+AHRI_water_heater_binning_for_UEF_calcs.xlsx: Analysis of CEC and AHRI databases to determine Code/standard practice and Measure technology performance characteristics
  • DEER-WaterHeater-Calculator-v3.2.xlsm: (updated 25 Sept 2018) Water heater impacts calculation workbook for use in 2019 (which corrects an error in the previously released version). This workbook has been updated to reflect revised measure technology definitions  which use UEF replacing EF for the rating
  • DEER-WaterHeater-Calculator-v3.3.xlsm: Water heater impacts calculation workbook for DEER2020. This workbook has been updated to use the DEER2020 vintage and and peak period definitions. The gas water heater measures are included in the PEAR database as part of the DEER2020 update.

Accelerated Replacement NTG Values for DEER2019

Decision 16-08-019 and Resolution E-4818 established an expanded framework for applying the accelerated replacement dual baseline approach where savings are estimated above the existing baseline for the RUL and above the standard practice or code baseline for the post-RUL period (equal to the EUL minus the RUL of the replaced equipment).  Similarly, the use of normalized metered energy consumption (NMEC) for estimating savings is based on the existing equipment baseline. Historically, evaluation results at either the measure level or program activity level have been presented as a single net-to-gross value that was not differentiated based on the measure application type (such as accelerated replacement or normal replacement) or baseline (i.e. existing conditions, standard practice or code). DEER adopts an approach for developing an appropriate NTG values for AR and NMEC measures and projects based on existing DEER NTG values modified by a methodology adopted by D.17-09-025 as used in the develop of energy savings goals.

Peak Period Update

Resolution E-4867, issued August 24, 2017, which approved the DEER2019 update and revisions to DEER2017 and DEER2018, ordered the utilities to establish a working group to propose adjustments to the definition of the Peak Period. This working group convened two meetings, which occurred April 3 and 16, 2018, and produced a report on May 4, 2018. The recommendation in the working group report were considered along with comments on the report and additional considerations as noted in the Resolution E-4952. The Peak Period definition change is proposed for adoption as noted below.

Peak demand savings for DEER measures were re-evaluated based the order by the CPUC to update the peak period definition as quoted below.

Resolution E-4952 Ordering Paragraph 1: Effective January 1, 2020 the DEER demand reduction shall be defined as the average demand impact as would be “seen” at the electric grid level for a measure averaged across 15 hours from 4 p.m. to 9 p.m. during the three consecutive weekday period containing the highest algebraic sum of: the average temperature over the three-day period, the average temperature from noon to 6 p.m. over the three day period, and the peak temperature within the three-day period. The three Peak Period days shall not include a holiday, and shall fall within the dates of June 1 through September 30, inclusive.  Holidays within the possible peak dates include the nearest weekday to the Fourth of July, and Labor Day. A Peak Period shall be selected for each of the 16 California climate zones, based on the most current weather data sets and day-of-week sequencing adopted for the California Title 24 Building Energy Efficiency Standards, as published by the California Energy Commission.

The new peak period definition utilizes the same three-day heat wave as defined for each climate zone in the previous versions of DEER.  A workbook developed for DEER2014 (see CZ2010 Peak Period Determination - v3.xlsm) contains the data and calculations used to select the peak days for each of the 16 California climate zones adopted by the California Energy Commission for use in Title 24 Building Energy Efficiency Standards analysis. As noted above, the new peak period is from 4 p.m. to 9 p.m. instead of the previous 2 p.m. to 5 p.m. interval. All previous DEER measures with no expiration date, or with an expiration date after December 31, 2019 have updated peak demand savings based on the new peak period definition.

Lighting HVAC interactive effects (IE) values are updated based on the new peak period definition and other updates and fixes applied to the simulation prototypes as noted below. The IE tables have been updated for 2020 and are available in the Support Tables section of READI in the Energy Impacts group, and have been compiled into a single Lighting HVAC IE workbook. Updated weights tables and the Residential and Commercial HVAC IE development workbooks are also available.

Efficient Furnace Fan Motor

The commercial and residential furnace measures were updated and augmented to include the option of higher efficiency supply-air fan motors. The previous furnace efficiency measures include only impacts to the gas consumption of the higher-efficiency furnace. The ECM furnace fan motor was estimated to save 18% on average compared to the baseline Permanent Split Capacitor (PSC) motor. The derivation of this estimate is provided in DEER2020_FurnaceFan.xlsx.

Expanded HVAC Savings Methods

To support development of alternative measure definitions for chillers, and to extend the DEER chiller savings calculation methods to custom projects, DEER now includes a chiller savings calculation workbook, DEER2020_Chiller_Workbook-v1.xlsx, which utilizes the DEER chiller simulation results to develop savings of chiller measures that incorporate designated non-DEER measure characteristics. Detailed guidelines for project inputs, chiller inputs and calculation results are provided the document DEER2020_Chiller_Workbook Guide.

A set of chiller efficiency measures has been added for the scenario in which a single chiller in a multi-chiller cooling plant is replaced with a higher efficiency unit, and that unit is operated as the lead chiller throughout the year. The “lead chiller” has much higher operating hours and therefore these measures will have higher savings per ton. Lead chiller measures may only be utilized in custom programs and shall not be used in deemed downstream rebate, upstream incentive or direct install programs. Custom programs for lead chiller measures shall include pre- and post-installation measurement and verifications that support the measure chiller is installed and operating as the lead chiller.

The workbook DEER2020-DEER2017_ChillerImpacts_Comparison.xlsx provides a comparison of DEER2020 and DEER2017 impacts for chiller measures with the same measure performance characteristics.

Note (30 September 2018): During the development of the DEER2020 chiller results errors were noticed in the DEER2017 June 2017 update and DEER2019 chiller modeling. The peak demand period was not correctly updated for the CEC Title 24 weather file update and an error was found in the screw chiller performance curves. These errors have been corrected and updated workbooks and chiller modeling archives can be found on the DEER2017 page and the DEER2019 and June 2017 Update page.

Commercial Prototype Update

The DEER commercial energy simulation prototypes have been updated to account for all the lighting systems and activity areas defined in the DEER2016 update. Development of the updated prototypes also led to several changes to the building model assumptions. Some of these changes were needed to support the expanded activity area definitions and others were a result of the more flexible modeling framework of the new prototypes. The extensive re-development of the prototypes also led to critical review and updates of a number of model parameters, which are documented in DEER2020_Prototype_Changes.xlsx.

Building Vintage Consolidation

The DEER modeling process has used building vintages to distinguish the differing building and building system characteristics associated with the age of relevant buildings stock being served by an IOU. Each new DEER version considered changes to the definition of the new building vintage, based on code updates and improved standard practice, as well as how the lighting and HVAC system characteristics of older vintages may have changed. With many DEER updates over the past 15 years a new building vintage was defined and existing building vintage definitions were updated. This has led to defining unique characteristics for as many as 10 distinct building vintages for a single building type. For all but a few building shell measures in DEER, the vintage-specific energy impacts of a measure were rolled up into a single "existing building" vintage. The vintage-specific measure energy impacts that determined from energy simulations were rolled up based on the estimated total area of a given building type associated with each building vintage. Since the total area associated with the more recent vintages for any building type is always small compared to the total area of the older vintages for the same building type, the existing vintage was overwhelmingly representative of the older building vintage energy impacts.

For DEER2020, a new approach has been developed to eliminate the 10 individual vintage definitions as well as the "existing" vintage definition. Instead, there are three vintage classifications that represent existing buildings of different age ranges, and one new building vintage:

  • Old: Before 2002 for non-mobile homes, before 1995 for mobile homes
  • Median: 2002 to 2016 for non-mobile homes, 1995 to 2005 for mobile homes
  • Recent: 2017 to present for non-mobile homes, 2006 to present for mobile homes
  • New: new construction for any building type

The median vintage is defined with lighting and HVAC systems that cover the range of their respective EULs. As such, the median vintage is the most appropriate vintage to utilize for claims of measures that are applied to buildings whose age is unknown or undocumented. Note: for DEER2020, the code used for the median vintage is "ex" so that references to the previous existing vintage will be compatible with the updated measure energy impact results.

As a part of the vintage consolidation, several characteristics of multizone and central plant HVAC systems were updated to account for equipment upgrades that would likely have occurred in those buildings. All motor efficiencies and controls, supply air temperature controls, and duct insulation levels have been updated for the oldest two vintages to bring them up to the level of the 1996 vintage. Details are provided in DEER2020_Prototype_Changes.xlsx.

Commercial Building Outside Air

The outdoor air ventilation requirements of the commercial building prototypes are based on an adjustment to the required outdoor air flow per person along with the code-based egress requirements that specify the design area per person ; the code recommended adjustment to the egress-based occupancy rates differs from the adjustment used in the development of previous DEER versions. This correction has been applied to both occupant density and outdoor air ventilation requirements to be consistent with the code requirements. The new values used for DEER2020 and the previous DEER values are listed in DEER2020_Ventilation.xlsx. The median change in occupant density is a decrease of 25%, and the median change in ventilation requirement is a 50% increase as compared with previous DEER versions.

Other Corrections

Miscellaneous corrections are as follows:

  • Residential windows in DEER2017 were oversized by 18% due to an error in the application of window frame width.
  • The fan power relationship for two speed AC and HP measures was incorrect in DEER2017. The correction for DEER2020 results in fan power reduction in the low speed mode of approximately 15%.

Commercial HVAC Energy Code

Updates in the 2019 Title-24 requirements for commercial buildings include expanded ventilation (outdoor-air flow) rates by activity area, increased exhaust-air flow rates for some activity areas and increased values for cooling tower efficiency. These updates, which have been incorporated into the 2020 DEER building vintage and the new construction DEER building vintage prototype models, are expected to have minor effects on measure savings. Details of the updated values are listed in DEER2020_CodeUpdates.xlsx and DEER2020_Ventilation.xlsx.

Residential Shell Energy Code

Updates in the 2019 Title-24 requirements for residential buildings include changes to the roof insulation configuration in single-family buildings along with lower framed wall U-value for single-family buildings and improved window specifications for single-family and multi-family buildings. These updates have been incorporated into the 2020 DEER building vintage prototype models. Overall, wall insulation increases about 7%, and window performance increases about 5%. Attic radiant barrier requirements have been removed from several climate zones, and roof insulation requirements are slightly more stringent, and will result in reduced savings from duct loss measures. Details of the updated values are listed in DEER2020_CodeUpdates.xlsx.

Net-to-Gross

Updates to HVAC measures reflect recent ex post evaluations: Residential HVAC maintenance and non-residential HVAC maintenance and upstream packaged measure NTG values are updated, effective January 1, 2020, based on recent evaluation results.

Direct Install to Hard-To-Reach NTG retained: Since the 2008 version, DEER has included a higher NTG value of 0.85 for direct install deemed measures into hard-to-reach markets. Commission staff reviewed the evidence gained through almost ten years of evaluation results. In review of the most recent evaluation results along with overall 2017 deemed claims, Commission staff does not find there to be a preponderance of evidence to support reducing the NTG value for direct install programs into HTR markets to equal that for the general market. A review of 2017 claims (see 2017-HTRNTG-DeemedClaims-21Aug2018.xlsx) shows that over 50% of HTR NTG claims are for lighting lamp or fixture measures with higher measure level NTG values than the existing HTR value.

Other NTG updates

Commission staff have completed a comprehensive review of the DEER NTG values along with NTG values that have been assigned to deemed measures through recent workpaper dispositions. Many NTG values are now revised, removed or combined with other NTG values to reflect most recent workpaper dispositions, evaluation results or code changes.

Out-of-date measure criteria:  Some measures have incorrect measure specifications and in some cases there are no current evaluation results to support an NTG value that is different from the DEER default. Such values have been updated, removed or replaced.

Values that are not significantly different from the DEER defaults: In some cases, measure specific NTG values do not differ by a large amount from the DEER defaults. Such values have been removed.

Lighting NTG values to reflect recent dispositions: The 2018 Phase 1 lighting dispositions updated NTG values for all LED measures. The DEER2019 expands on these dispositions to revise the code/standard practice baseline for all hardwired LED fixtures to be a typical performing LED fixture.

Table simplification: Commission staff have revised the NTG table to remove most descriptive fields and substituted direction in the comments section that describes under what circumstances an NTG value shall be used. Criteria include measure type (deemed, custom, etc.), application type (NC, NR, AR, etc.) or delivery type (downstream, upstream, downstream DI, etc) and any measure technology requirements.

The updated NTG table is downloadable using the READI tool and also here (updated 18 Sept 2018).

Effective Useful Life

D.16-08-019 created he Behavioral, Operational and Retrocommissioning (BRO) measure classification with EUL values of one to three years with retrocommissioning assigned a three-year EUL. Resolution E-4818 directed that all measure which utilize a degraded performance baseline and/or are restorative of performance in nature be classified as retrocommissioning. The DEER EUL/RUL table has been updated to follow these policy directions. This policy direction was effective 1 January 2017.

Resolution E-4818 re-affirmed the long-standing policy that EUL values for add-on equipment measures (including wall, floor and ceiling insulation added to existing insulation) are limited to the RUL values of the host equipment. The only exception to this is when the add-on measure is part of a new installation in which case the EUL of the add-on equipment is limited by the EUL of the host equipment. This DEER update add specific language and provides examples to guide future application of this policy to measure EUL/RUL assignments.

LED screw-in lamps have a spread of manufacturers rated life values ranging from 25,000 to 50,000 hours with an Energy Star minimum requirement of 25,000 hours. These ratings are based upon a specific test method that may not provide results that are a good indicator of expected life in real installations. The results of CPUC laboratory test show that LED A-lamps are unlikely to obtain their rated life or even the Commission staff approved value of 20,000 hours. Based on the testing result the LED screw-in A-Lamp life is reduced from 20,000 hours to 10,000 hours. This change is effective 1 January 2019.

The updated EUL table is downloadable using the READI tool.

Custom Project/Measure GRR

Although an update to the default gross realization rate for custom measures and projects is within the scope of this Resolution, Staff determined that the values established by Decision 11-07-030 may not be modified through this Resolution, thus remain 0.90 at this time. The results of recent CPUC sponsored laboratory testing show that LED A-lamps are unlikely to obtain their rated life or even the Commission staff approved value of 20,000 hours. Based on the testing results the  LED screw-in A-Lamp EUL is reduced from 20,000 hours to 10,000 hours effective 1 January 2019.

  • Notices of changes and updates to the DEER values that occur while in the review and comment period are posted to the PEAR change log.

Residential Baseline

Pursuant to Commission direction in E-4818 Commission staff investigated available data sources for updates to existing condition baselines for DEER measures. For residential measures, the source for baseline data review was the 2012 California Lighting and Appliance Saturation Study (CLASS). The CLASS database contains building characteristics and appliance efficiency data collected in on-site surveys of 2,000 residences. For this DEER update, values from the database were averaged to estimate existing baseline conditions. For appliance measures, equipment less than four years old at the time of the surveys was excluded from the averages. Since the surveys were conducted in 2012, this translates to current day averages that are based on equipment 9 years old or older. It was found that trends in appliance efficiency versus building vintage were weak, reflecting the fact that original appliances have been replaced in all but the most recent building vintages. Thus, a single baseline was established representing all building vintages. Workbooks used in the development of the new pre-existing values from the CLASS data are provided in DEER2017 Update supporting materials.

Residential Clothes Washer

The residential clothes washer measures were last updated for DEER2016. Impacts in the Ex-Ante database include values for both pre-existing and standard baselines.

For all DEER2016 clothes washer measures, the pre-existing baseline used a Modified Energy Factor (MEF) value of 1.29, regardless of building vintage, however, the average efficiency for existing top loading washers from the CLASS database was found to be 1.50 MEF, and the average for front loading washers was 2.14 MEF. Development of clothes washer baselines is included in the CLASS Clothes Washer Baseline workbook. Additionally, the DEER2016 pre-existing baseline for front loading washers was based on typical efficiency values of top loading machines. This represented a technology switch, which is not allowed in DEER and is not consistent with the new federal standard, which rates front loading units separately. Details of the clothes washer measure development are included in the DEER Update Clothes Washer workbook. The clothes washer comparison workbook provides details on how each measures definition has changed and the associated change in energy impacts. Refer to Section 1.1 of the DEER update documentation for more information on clothes washer measure updates.

Residential Refrigerators and Freezers

Residential refrigerator and freezer measures were revised in for the DEER2017 update to consider building prototype revisions. However, measure definitions did not include pre-existing efficiency levels and all above pre-existing energy impacts were reported as zero. For this update, a pre-existing technology is established based on CLASS data for refrigerators and freezers four years old or older at the time of the survey (these units would be at least nine years old in 2017). Development of refrigerator and freezer baselines is included in the CLASS Refrigerator Baseline workbook and the CLASS Freezer Baseline workbook. Refer to Section 1.2 of the DEER update documentation for more information on refrigerator and freezer measure updates

Residential Water Heaters

Residential small storage, instantaneous and heat pump water heater measures were last updated in DEER2015. The CLASS database shows only minor differences in water heater efficiencies relative to building vintage, whereas the DEER2015 pre-existing baselines were significantly worse for older vintages than for newer vintages. For this update, the DEER pre-existing baseline for each residential water heater type is updated using CLASS data averaged across the building vintages. Development of refrigerator and freezer baselines is included in the CLASS Water Heater Baseline workbook.

Heat pump water heater measures were last updated for DEER2015. Since then, the Energy Factor (EF) of available water heaters has increased dramatically, and lower efficiency units are no longer available. At this time, all heat pump water heaters available from major California retailers have EF values greater than 3.0. Therefore, the Code/Standard baseline of all heat pump water heaters has been revised to be a standard practice baseline of 3.0 EF. Measure efficiency levels are also revised to be representative of the most efficient products currently available based on examination of manufacturers' literature. Information on the market analysis of available heat pump water heaters is found in the DEER2017 Update Heat Pump Water Heaters workbook.

The energy impacts for all residential hot water heater measures are re-calculated using the Updated DEER DHW Calculator workbook. Refer to Section 1.3 of the DEER update documentation for more information on water heater measure updates.

Residential Gas Furnace

Residential gas furnace measures were included in the DEER2017 update to consider building prototype revisions. The pre-existing baseline efficiency for DEER2017 was 78% for vintages through 2014, and 80% thereafter. Review of the CLASS database revealed an average furnace efficiency of 80% for existing systems, which is the same as the code value that has been in place since 2015. Development of gas furnace baselines is included in the CLASS Furnace Baseline workbook. Therefore, to-code savings for the DEER2017 Update will be zero for residential gas furnaces. PAs may propose alternative existing baseline values, however, claims must be supported by workpapers for accelerated replacement that specify how the proof of pre-existing equipment efficiency will be collected and stored with project files and supplied to support accelerated replacement savings claims. Refer to Section 1.4 of the DEER update documentation for more information on residential furnace measure updates.

Residential Air Conditioners

Cooling efficiency measures were updated in DEER2017 to consider prototype revisions, code changes and performance map improvements. Pre-existing efficiency values for DEER2017 were SEER 10 for older vintages through 2005, SEER 13 from 2006 through 2014, and SEER 14 for 2015 and later. The average efficiency for pre-existing systems calculated from the CLASS database is SEER 11.4. Residential Air Conditioning (AC) measure technologies were not affected by the baseline update. Since only the pre-existing baselines were affected, above code impacts have not changed. Development of air conditioner baselines is included in the CLASS Cooling Baseline workbook. Energy impacts for the affected measures were determined by weighting the existing above pre-existing energy impacts with the above-code/std energy impacts based on the target efficiency level. The scaled impacts workbook develops the new impacts and compares the measure savings to the previous version. Refer to Section 1.5 of the DEER update documentation for more information on residential air conditioner measure updates.

Net-to-Gross Updates to Address Direction in E-4818

For this DEER update, Commission staff adds an adjustment factor to the DEER NTG table designed to provide an appropriate adjustment to the normal replacement NTG values for use with the measure when given an accelerated replacement measure type designation. The adjustment factor provides an incremental free ridership fraction for the to-code portion (RUL period) of the accelerated replacement savings calculation. The normal replacement NTG provides the net of free ridership for the above code portion of the saving while the new "accelerated replacement NTG adjustment factor" (AFAR) provides an increment to the free ridership for the below code portion of the savings. The adjustment will reduce the net-to-gross value for the to-code savings to account for customers who were not influenced by a program to replace the existing equipment or systems prior to the end of the useful life. More information on the development of values for AFAR are included in the DEER2017 Update To-Code NTG workbook.

Commercial Variable Refrigerant Flow HVAC Systems

In March 2017 Commission staff issued a Phase 1 disposition covering VRF measures. The disposition includes direction for updates to energy savings values for a limited number of DEER building types. For the current update the VRF efficiency measure assessment has been expanded to include additional building types and system capacity ranges, and the results have been added to the official Ex-Ante Database for DEER2017. Measure tiers for VRF systems have been established by a review of data from the product database published by the Air-Conditioning, Heating and Refrigeration Institute (AHRI). A limitation was placed on lowest efficiency tier that these units must be at least 15% higher than the code EER. Refer to Section 2.2 of the DEER update documentation for more information on revisions to VRF measures. Documentation of the March 2017 assessment and the updated VRF modeling tools are posted in the file [VRF_Reports_And_Modeling_Tools.zip].

Commercial Air Conditioner and Heat Pump Systems

The last significant update for commercial unitary air conditioners and heat pumps was in DEER2015. This update included all AC and heat pump (HP) units below 65 kBtu/hr, and all AC units 65 kBtu/hr and greater. The pre-existing baselines in DEER2015 were based on historic code requirements. For buildings built before 2002, it was assumed that the air conditioners had been updated to the efficiency level of the 2002 to 2005 vintage. A review of the California Commercial Saturation Survey (CSS) shows efficiency levels that are significantly above the DEER2015 pre-existing baselines for most equipment size categories. Since CSS was completed in 2012, the supporting data represents equipment that, today, would be at least 5 years or old. A survey of claims from the SCE Packaged HVAC Early Retirement Program shows that there are relatively few claims where the replaced system is less than 9 years old. For this update, existing baselines were updated to reflect efficiencies in CSS. In cases where limited or no data existed, the existing baseline was set to the applicable code value. Development of air conditioner baselines is included in the CSS Air Conditioner Baseline workbook. PAs may claim existing baseline efficiencies, however, claims must be supported by workpapers for accelerated replacement that specify how the proof of pre-existing equipment efficiency will be collected and stored with project files and supplied to support accelerated replacement savings claims.

A review of SCE Packaged HVAC Early Retirement Program shows that most equipment larger than 20 tons are variable volume systems. Based on this data, constant volume systems in the largest size range have been removed from DEER in order to prevent accidental claims of VAV systems as if they were constant volume. For the 240 to 760 kBtu/hr size range, a single weighed measure has been implemented in DEER based on the population data from the claims. The constant volume and VAV measures are retained in the database as component-type measures for reference. Claims analysis of SCE’s early retirement program are included in the SCE Early Retirement workbook.

Refer to Section 1.5 of the DEER update documentation for more information on non-residential air conditioner measure updates.

In the process of reviewing baseline updates two errors were discovered in the DEER2015 analysis of SEER rated air conditioning and heat pump systems for commercial buildings. The first error was applicable to all one-speed split air conditioners less than 65 kBtu/hr, as well as all one-speed split and packaged heat pump systems less than 65 kBtu/hr. This error was due to an incorrect minimum threshold for the cycling loss performance curve, and the result was an underestimation of energy use for the affected simulations, which were always either pre-existing or code level models. Thus, correction of the error will result in slight increases in impacts for those measures.

The second error was applicable to all split and packaged air conditioning and heat pump systems in the 55 to 65 kBtu/hr capacity range. For these situations, the code level system was incorrectly set up as a two-speed unit instead of a one-speed unit. This resulted in underestimation of the code model energy use, so correcting the error will increase to-code impacts. In accordance with this correction, the SEER 15 measure was also changed from a two-speed unit to a single speed unit. This correction results in significant increases in savings for cases where the code changes to constant speed while the measure remains at two-speed.

The scaled impacts workbook develops the new impacts and compares the measure savings to the previous version. Refer to Section 3.1 of the DEER update documentation for more information on measure corrections for non-residential SEER rated HVAC systems.

Commercial Chillers

The 2017DEER included updates to water chiller measures that included both minimum full-load efficiency (kW/ton for water-cooled machines or EER for air-cooled machines) and minimum integrated part-load efficiency (IPLV) values. Program administrators (PAs) have voiced concerns that the minimum IPLV requirements were set at efficiency levels that are better than nearly all equipment currently available in the marketplace. The DEER2017 update addresses this problem by setting minimum measure requirements for both full-load and integrated part-load efficiency to be at least 10% better than Title 24 minimum requirements. PAs also were concerned that DEER did not include measures for variable speed positive displacement machines, which are becoming more common. This update also includes new measures for variable speed screw chillers, which are the most common types of positive displacement chillers.

For more information see Section 3.3 of the DEER2017/2018/2019 update documentation. More details on revised measure definitions, including details on screw chiller performance characteristics, can be found in the DEER2017 Update Chiller Measures workbook. The complete set of simulation files for the new screw chiller measures can be found in the DEER2017 Update Chiller Models Archive.

(Updated September 28, 2018) DEER2017 chiller measures included peak demand savings based on an out-of-date demand period. New Additionally, the performance map for the variable speed screw chiller included an error in the development of the performance curve that sets the chiller power input as a function of part-load-ratio, entering condenser temperature and leaving chilled water temperature.  The DEER2019 update corrects these errors. More details on revised measure definitions, including details on screw chiller performance characteristics, can be found in the DEER2017 Update Chiller Measures workbook. The complete set of simulation files for the new screw chiller measures can be found in the DEER2017 Update Chiller Models Archive.

Residential Clothes Washer Code Update

The new federal standard for top loading clothes washers goes into effect on 1/1/2018. This code update changes the IMEF for standard capacity top loading clothes washers from the DEER2017 code value of 1.50 to the new federal standard value of 1.57.

For the DEER Top-loading clothes washers, the savings based on the pre-existing technology will not change from the DEER2017 results. Measure energy impacts above the code/standard technology will decrease by approximately 12% starting in 2018 compared to the DEER2017 energy impacts. Refer to Section 4.1 of the DEER Update Documentation for more information on clothes washer measure code updates.

Residential Refrigerant Charge

During the development of the updates for the non-residential refrigerant change adjustment (RCA) measure described below, the DEER team discovered a mistake in the calculation methodology. The previous measure modeling was done using measure assumption parameters developed by weighting together model input parameters for systems with thermal expansion valves (TXV) and those with non-TXV devices rather than weighting together the modeling results for TXV and non-TXV devices. Measures are now differentiated between systems with and without TXV devices. For systems with non-TXV control, the change from the original DEER2018 results is minimal, since this was weighted heavily in the measure inputs. However, systems with TXV control have much lower savings for undercharged systems, and effectively zero savings for overcharged systems. Development of RCA is covered in the Residential Refrigerant Charge workbook. Refer to Section 3.2 of the DEER update documentation for more information on residential RCA measures.

Net-to-Gross Review

The DEER team reviewed recent EM&V findings and updated net-to-gross (NTG) values where EM&V findings indicate a substantial difference from current DEER values. The DEER team opinion is that evaluation results moving up or down less than five percent annually should not result in a shift in the DEER ex ante values unless there is evidence from two or more consecutive evaluations that the change represents a directional shift that is expected to persist into the future rather than simply a normal year-to-year change in participation or measure mix that can move NTG values either up or down. When an upward or downward trend is observed the DEER team also considered that these values will be applied four years later than the program year for which the evaluation was performed and thus additional adjustments may be warranted. Therefore, Commission staff recommends only the limited NTG adjustments. Refer to Section 5.1 of the DEER update documentation for more information on NTG updates.

Commercial Refrigerant Charge

Commercial refrigerant charge adjustment (RCA) measures were last revised in DEER2014. The DEER team used data from recent laboratory investigations of RCA to develop adjustments to cooling capacity and efficiency of package HVAC systems. Adjustments are different for systems with thermal expansion valves (TXVs) and systems without TXVs. Data show that improvement in electric input ratio (EIR) is much lower than was assumed for DEER2014 values, especially for overcharged systems. Additionally, difficulty in precise measurements and diagnosis in the field for these small off-charge states makes it difficult to establish that small charge adjustments will result in any improved system state or performance. For these reasons the DEER savings values are only to be utilized for charge adjustments of four percent or greater and shall only be allowed if the technicians are utilizing approved methods and tools and have undergone approved training by a qualified professional. In order to use the DEER savings values, the implementation activities must include a continuous verification element that ensures that the approved system fault diagnosis and correction protocols are being followed and that any charge adjustments are necessary and correct. RCA data analysis is included in the Commercial RCA Data workbook. Development of refrigerant charge measures is covered in the Commercial Refrigerant Charge workbook. Refer to Section 5.2 of the DEER update documentation for more information on nonresidential RCA measures.
