This Technical Manual explains the requirements for the California Home Energy Rating System (HERS) Program, including requirements for HERS Providers, modeling procedures and assumptions for HERS software, and procedures for California Whole‐House Home Energy Raters. HERS rating software is used to calculate the California HERS Index, generate recommendations on how to improve the energy performance of the rated home, and analyze customers’ utility bills. The Technical Manual also explains the roles, requirements, and procedures for persons certified to perform specific functions related to HERS ratings. The Technical Manual explains the requirements for completion of California Home Energy Audits that are provided for people who do not wish to
have a formal rating but want recommendations for cost‐effective energy efficiency improvements. The Technical Manual also explains the HERS reports, data collection procedures, and certification and quality assurance procedures.
