The Energy Commission has prepared a Notice of Proposed Action (NOPA) and an Initial Statement of Reasons (ISOR) regarding the need for the proposed amendments. These two documents will be published and accessible online on October 3, 2008, at the Energy Commission's website specified below.

The NOPA will announce the availability of the Express Terms (45-Day Language) of the proposed amendments to the existing HERS Program regulations, including the HERS Technical Manual that is incorporated by reference. The Express Terms, including the HERS Technical Manual, can be obtained on September 30, 2008, from the contact person designated below or from the Energy Commission's website at:


Public Resources Code (PRC) Section 25942 directs the Energy Commission to adopt a statewide HERS program for residential dwellings. Phase II rulemaking of the HERS program will put in place the following remaining elements of PRC Section 25942 necessary to extend the HERS Program to whole-house energy ratings of existing and newly constructed homes:

  • Consistent, accurate, and uniform ratings based on a single statewide rating scale;
  • Reasonable estimates of potential utility bill savings, and reliable recommendations on cost-effective measures to improve energy efficiency; and
  • Labeling procedures that will meet the needs of home buyers, homeowners, renters, the real estate industry, and mortgage lenders with an interest in home energy ratings.

Phase I of the HERS Program was adopted in 1999 and established the basic operating framework of the program, including training and certification procedures for raters, quality assurance procedures, and data collecting and reporting requirements for raters who are performing field verification and diagnostic testing services for demonstrating compliance with Title 24 Building Energy Efficiency Standards.

Phase II will extend Phase I of the HERS Program to include methodologies for calculating a California HERS Index and analyzing utility bills and cost-effectiveness of energy efficiency measures. Phase II will further address whole-house energy ratings and certification of individuals who would be involved in the California HERS Program, including raters, energy auditors, energy inspectors, energy analysts, and building performance contractors.
