Title 24, Part 6 Building Energy Efficiency Standards (the Energy Code) are part of the California Code of Regulations and are included in California’s overall Title 24 Building Standards Code.
California’s Energy Code promotes efficient building energy use to protect people and the environment. For example, the California Energy Commission estimates that single-family homes built in compliance with the 2022 Energy Code will use about seven percent less energy due to energy-efficiency measures versus those built under the 2019 Energy Code. Once rooftop solar electricity generation is factored in, homes built under the 2019 standards will use about 53 percent less energy than those under the 2016 standards. This may reduce greenhouse gas emissions by 700,000 metric tons over three years, equivalent to taking 115,000 fossil fuel cars off the road. Additionally, California’s energy codes and standards have helped keep California’s per capita energy consumption much lower than the rest of the nation for decades.
