The California Energy Commission (CEC) started this order instituting rulemaking proceeding so all stakeholders and other interested persons may participate in the consideration of the following:

  1. Relocate the field verification and diagnostic testing program data collection requirements from HERS program (22-HERS-02) to the Energy Code (22-BSTD-03)
  2. Improve CEC oversight and program performance by adding or amending provisions for progressive discipline, quality assurance procedures, conflict of interest, rater designation, approval processes, training requirements; and amendments which clarify other sections, as necessary

See the full text of the CEC Order Instituting Rulemaking.

The CEC uses a public process and a rulemaking to adopt changes to the HERS Program (Title 20, California Code of Regulations, sections 1670-1675) and the Energy Code contained in the California Code of Regulations (CCR), Title 24, Part 6, and associated administrative regulations in Part 1 (collectively considered the Energy Code).

The updated HERS Program regulations will be proposed for adoption in 2023 with an effective date of January 1, 2026, and the Energy Code standards will be proposed for adoption in 2024 with an effective date of January 1, 2026. See the public participation section below for more information.
