DEER2014/2013 Update

On November 25, 2013, the CPUC released the latest version of DEER (Database for Energy Efficiency Resources). 

The DEER update, previously referred to as "DEER2013", will be referenced as "DEER2014" moving forward. The naming convention refers to the year when the updated values become applicable to avoid confusion. Previously, the naming convention refers to the year when the updated values are being published. 

DEER2014 is an update of DEER2011 required by Codes and Standards (C&S) changes which are effective in 2014. The C&S updates include the California Title 20 Appliance Efficiency Regulations, the California Title 24 Building Energy Efficiency Standards, and the United States Code of Federal Regulations. These C&S updates are incorporated into all energy saving measure definitions and new construction building descriptions for DEER2013. 

The READI tool to view the database and the update documentation are all available on

The latest version of the READI tool (v1.0.3) includes the following changes: 

  • Available databases: DEER2014 Code Update, DEER2011, and Ex Ante 13-14 Cycle (draft combination of DEER2011 and DEER2014) 
  • Alerts user which database is being connected on start-up. 
  • More fields within the Measure, Energy Impact, and Measure Catalog tables are now linked to their source tables. Double-click on any field that has a blue “highlight” font to get additional information. 
  • The “Implementation” tab is now only available for the “Ex Ante 13-14 Cycle” combined database. It has been renamed to “Measure Catalog” to better communicate the function of the table.
    • Measure Catalog entries are based on IOU workpapers and connect all ex ante data to a measure catalog entry. 
    • A field specifying the start date of the catalog entry has been added. This allows a reference to a Measure Catalog ID to have different linked values based on a reference date. 
    • A field specifying the Measure Impact Qualifier has been added. 
    • Double-click on a row of the Measure Catalog list to create a table of all ex ante values associated with the entry.
