The California Energy Code (also titled Building Energy Efficiency Standards for Residential and Nonresidential Buildings), called simply Title 24 in industry, is the sixth section of the California Building Standards Code. The code was created by the California Building Standards Commission in 1978 in response to a legislative mandate to reduce California's energy consumption. These standards are updated periodically by the California Energy Commission. The code includes energy conservation standards applicable to most buildings throughout California.^[1]

The code's purpose is to advance the state's energy policy, develop renewable energy sources and prepare for energy emergencies.^{[citation needed]} A 2020 study found that the 1978 energy code successfully reduced energy consumption, and that the implementation of the policy passed a cost-benefit test.^[2]
