  • The Appliance Recycling Program (ARP) measures have been updated based on commission direction and DEER-team identified errors in the proposed values and will have an effective date of 1/1/2016.
  • The ARP Net-to-Gross values have been updated due to the ARP impact values update mentioned above.
  • The supporting documentation on ARP analysis and results have been updated and augmented. See the 2015 Uncertain Measures Update page under the DEER Versions menu for the updated documentation.
Updated 2015-10-20
2015-10-16 Update DEER2016 NTG The DEER2016 NTG update workbook and NTG database table have been revised for clarity and to allow all rows to be displayed within the READI Support Tables. The updates are highlighted in the workbook and include a revision to the specified DeliveryType field for 11 of the NTG records. None of the NTG IDs or values have changed with this update. Updated 2015-10-16
2015-10-09 Correction DEER EnergyImpact The Residential Common-Area Lighting energy impacts are corrected. The previous values included demand values in Watts instead of kiloWatts (i.e. were 1000x too large). Thanks to engineers at SCE for providing the information leading to this correction. See this workbook for a list of all measures affected.

The 2016 Lighting Summary support tables is corrected. The CDF and EFLH fields in the previous version was not fully updated from the previous DEER2014 Lighting Summary table.
Updated 2015-10-09
2015-09-04 Addition DEER2016 exante1314
DEER Cost records added to the MeasureCost table and Cost references added to DEER measures that utilize these cost records. Also, a number of changes and additions have been made to support cost-effectiveness processing for 2016 claims:
  • Start and Expiry dates are added to the GSIA and EUL tables to support cost-effectiveness values processing.
  • Status field in the main ex ante tables have been updated to reflect a record's availability to Claims. Status is either:
    • Available: available for use in Claims
    • Proposed: record is a proposed addition currently in the review period
    • NotAvailable: record is not available for use in Claims
    • Other: this is a temporary status used to transition some 2013-14 PA ex ante data for use in 2016 claims, equivalent to NotAvailable but may be updated to Available as the PA ex ante data applicability is verified
  • ReviewStatus field added to main ex ante tables to augment the status field and/or document how a Status was determined
  • MeasType (Measure Type) field added to Measure table to identify measures used for processing. This information was previously part of the Status field.
  • PA-specific Measure ID fields are added to the Measure table to allow PAs to identify DEER Measures based on their internal codes. This field is for PA reference and documentation only, it is not a required field:
    • MeasID_PGE: a PG&E measure ID for the Measure record.
    • MeasID_SCE: a SCE measure ID for the Measure record.
    • MeasID_SDG: a SDG&E measure ID for the Measure record.
    • MeasID_SCG: a SoCalGas measure ID for the Measure record.
  • The optional Implementation.MeasEnQual field is renamed to MeasQualifier and the optional Measure.Qualifier field is renamed to MeasQualifierGroup to be consistent with how the fields are used when determing cost effectiveness values.
  • DEER2015 measures with the same MeasureID but with a different Version have been assigned a MeasQualifierGroup to facilitate referencing specific versions from an Implementation record, the MeasureIDs have not changed:
    • RG-WtrHt-SmlStrg-Gas-lte75kBtuh-30G-0p65EF

Updated 2014-11-07
2014-11-07 Correction DEER2011 exante1314
For the DEER2011 dishwasher measures it was determined that the typical pre-existing dishwasher met or exceeded existing code requirements. The code/standard technology case for these measures should have been defined the same as the pre-existing technology. Instead, the code/standard technology was undefined and therefore above code/standard energy impacts for the DEER2011 dishwasher measures are zero. With this correction, the code/standard technology is specified to be the same as the pre-existing technology and above-code/standard energy impacts are corrected to be the same as above pre-existing energy impacts for the following DEER2011 Measures:
  • Dishwasher-EnStar-Level1-wtd
  • Dishwasher-EnStar-Level2-wtd
  • Appl-Dishwash-StdSize-ElecDHW-0p65EF
  • Appl-Dishwash-StdSize-ElecDHW-0p68EF
  • Appl-Dishwash-StdSize-GasDHW-0p65EF
  • Appl-Dishwash-StdSize-GasDHW-0p68EF
Updated 2014-11-07
2014-10-29 Correction DEER2014 exante1314 An error in the technology specification results in zero energy savings being reported for two measures in the exante1314 database:
  • Res-Lighting-InGen_CFLratio0409_CFLscw-Refl-15w
  • Res-Lighting-InGen_CFLratio0409_CFLscw-Refl-23w
These measures and associated energy impacts were correct in the DEER2011 and DEER2014 versions of the database and have now been fixed in the combined database.

2014-02-12 Addition DEER2014 EnergyImpact The weighting of energy impacts for three HVAC measures has been updated. Prior to this update, these measures incorrectly weighted the "zero impact" records for recent vintages (2014, 2011 and 2007 vintages) into the "existing" vintage energy impacts. The updated process weights only those vintages for which the measure is applicable (i.e. has savings) and leads to approximately a 10% increase for the existing vintage energy impacts for the following commercial HVAC measures:
  • NE-HVAC-airAC-Pkg-lt55kBtuh-13p0seer
  • NE-HVAC-airAC-Split-lt55kBtuh-13p0seer
  • NE-HVAC-airHP-Split-lt55kBtuh-13p0seer-7p7hspf
In addition to these updates, the "New" vintage results for commercial HVAC measures have been identified as improperly based on the 2011 vintage building specifications. For measures where the code level changed from 2011 to 2014 vintage, this error can result in very overstated savings. The "New" vintage results for commercial HVAC measures have been temporarily removed from DEER2014 while this issue is addressed.

2014-02-05 Addition DEER2014 EUL A number of database updates have been applied to the DEER2014 database:
  • Extra measure definitions from DEER2011 removed. These measures had no associated energy impacts because they were not part of the DEER2014 update.
  • EUL table updated with additional records and one change to prior values. Workbook posted on documents the EUL table update.
    • EUL records for CFL lamps with rated life of 6,000, 8,000 and 12,000 hours added.
    • EUL records for hot water equipment simplified by consolidating equipment specification variations that utilized the same EUL values.
    • Residential indoor CFL degradation factor changed to 0.523 from 0.5 to match value in DEER2008 documentation.

2014-01-31 Addition DEER2014 Measure DEER2011 measures and associated energy impacts that were not updated for the DEER2014 release but which remain applicable to the post-DEER2011 period, were added to the DEER2014 database. The measure definitions and energy impacts are the same as in the DEER2011 database. These measures include the green house measures (identified with "Grnhs-Shell-" in the Measure IDs) and the DEER2005 carry-over measures (identified with "D03-" in the Measure IDs). Updated 2014-01-31
2014-01-21 Update DEER2014 EnergyImpact Weighted energy impacts (Existing vintage, IOU territory and Com building type) for commercial CFL and Linear Fluorescent measures with occupancy sensors updated. The previous release (16-Jan-2014) updated the algorithm used to calculate the impacts for lighting measures with occupancy sensors, but the previous weighted energy impacts were not updated. Updated 2014-01-21
2013-12-03 Update DEER2014 Measure Lighting measures that were part of DEER2011 but removed from DEER2014 due to the code update still appeared in the DEER2014 Measure List, but had "zero" associated energy impacts. These measures have been removed from the DEER2014 measure list. Updated 2013-12-03
2013-11-25 Planned Update DEER2014 deer2104
A draft of the "Ex Ante 13-14 Cycle" database has been made available. This database combines DEER2011 and DEER2014 along with IOU ex ante data. To view this database, use the "Tools => Change Database" option and select "Ex Ante 13-14 Cycle" on the Select Database dialog.
  • Measure definitions that have not changed between DEER2011 and DEER2014 but whose energy impacts have been updated have a single measure definition in DEER1314.
    • The different sets of associated energy impacts are selectable for a given measure definition via the "Impact Qualifier" field.
    • The impact qualifier is presented as a pull-down list for those measures that have qualifiers. Measures that do not have qualifiers have a "Version" value of either DEER2011 or DEER2014.
    • For DEER2014 lighting measures, the impact qualifier is also used to present the occupancy sensor options.
  • Examples of Non-DEER IOU ex ante Measures, Energy Impacts and Measure Costs are included in this database. These records are translations of IOU workpapers and are presented for review and discussion.

2013-11-25 Planned Update DEER2014 deer2104
The DEER2013 database has been finalized and renamed to "DEER2014". This new convention references the first year the data are applicable. To view this database, use the "Tools => Change Database" option and select "DEER2014 Code Update" on the Select Database dialog.
  • The DEER2005 measures and energy impacts have been removed from DEER2014 and are retained in the DEER2011 version. These measures and energy impacts have not changed for this update.
  • The "Implementations" table and examples of non-DEER data that supported the Implementations table have been removed from this DEER version. The "Implementations" table has been rename "Measure Catalog" and is included in the combined DEER1314 database.
  • The Net-to-Gross Ratio table has been modified:
    • The "HTG" tag, included in the "Hard to Reach" NTGR entries has been changed to "HTR" for clarity.
    • The faucet aerator records have been given the same NTGR_ID, each with with its appropriate applicablity values. This allows a single Measure Catalog entry to connect to both single-family and multi-family ex ante values.
    • "All" Program Delivery Type changed to "Any" to support Measure Catalog link to cost effectiveness values.
  • The GSIA table has been modified:
    • Improved display of GSIA table by adding HTML summary.
    • Fixed the GSIA records for Residential measures that used "Com" in the GSIA_ID name by mistake.
    • GSIA ID: "MFm-IntCF-SCE" changed to "MFm-ExtCF-SCE" to fix typo.
