Title 24 | JA8
Title 24 is the Energy Efficiency Standards for Residential and Non-Residential Buildings in California. Title 24 addresses the energy efficiency of construction projects in the state (including new construction, remodeling, addition and commercial buildings).
California Title 24 building code regulations were established in 1978 in response to a legislative mandate to reduce energy consumption and to improve state’s energy efficiency. The title was adapted to control and enhance energy consumption in the state as it relates to construction of buildings. According to the commission, every building must adhere to certain rules before construction. These standards are contained in part 6 of the the California Building Standard Code, which is California Title 24 (California Energy Code).
