Here’s a link that explains the Auditors https://www.disclosuresource.com/downloads/HomeEnergyRating.pdf. Effective January 1, 2026, the FV&DT provisions are administered under the Energy Code Compliance (ECC) Program and appear in Title 24, Part 6 and the administrative regulations in Title 24, Part 1. to further separate the two. What is Title 24? That is the California Building Code. Part 6 is the Energy Code.https://www.disclosuresource.com/downloads/HomeEnergyRating.pdf

HERS Raters will now be called ECC Raters or ECC Technicians, ECC stands for Energy Code Compliance.
