The California Energy Commission is required by Public Resources Code Section 25942 to establish regulations for a statewide HERS Program to certify home energy rating services in California. The goal of the program is to provide reliable information to differentiate the energy efficiency levels among California homes and to guide investment in cost-effective home energy efficiency measures.
HERS tests or HERS verification are required to close out permits for most types of energy upgrades for residential and non-residential construction. We have completed thousands tests in Northern California.
