Title 24 Energy Code
Title 24 - Part 6, also known as the Energy Code, define the building energy efficiency standards for residential and nonresidential buildings in California. It is regulated by the California Energy Commission (CEC). These standards are aimed to reduce energy cost and increase reliability and availability of electricity, while improving building occupants comfort, and finally making more sustainable California’s energy future.
The low-rise residential standards regulate the design of the building envelope; the heating, ventilation and air-conditioning (HVAC) system; the water-heating system; and the lighting system. PV (Photovoltaics) Systems are required for new single family and multifamily buildings.
Title 24 Energy Compliance
New constructions, remodels, additions and ADUs are required to include a Title 24 Energy Certificate of Compliance (CFR1) with the permit application. Additionally, some local agencies have adopted ordinances requiring more stringent energy requirements than those set by California’s Energy Code (Title 24, Part 6).
New!
2022 T24 Energy Code
The 2022 Title 24 Energy Code is effective as of January 1, 2023. Any projects that apply for a permit on or after this date will be subject to the 2022 Energy Code. The new standards are aiming to keep reducing greenhouse gas emissions (GHG) while creating an energy system that is resilient to climate risks and with a low-carbon footprint.
Among important changes, the new Energy Code requires Electric Ready for mechanical equipment that Architects/Designers shall specify on plans. For additional information, you could download our Important Changes for Single-Family Buildings document:
