Energy Efficiency
The California Energy Commission (CEC) updates the Energy Code every three years. On September 11,2024, the CEC adopted the 2025 Energy Code. In December, it was approved by the California Building Standards Commission for inclusion into the California Building Standards Code. The 2025 Energy Code encourages efficient electric heat pumps, establishes electric-ready requirements for new homes, expands solar photovoltaic and battery storage standards, strengthens ventilation standards, and more. Buildings whose permit applications are applied for on or after January 1, 2026, must comply with the 2025 Energy Code.
