CA Title 24


The Warren-Alquist Act, enacted in 1976, mandated that the Energy Commission create and periodically update Building Energy Efficiency Standards for the state of California. These Standards address newly constructed buildings and additions and alterations to existing buildings. The Standards have, in combination with appliance efficiency standards and utility-sponsored incentive programs, strongly contributed to California's per capita electricity consumption levels remaining relatively flat since the mid-1970s. First adopted in 1977, the Standards have been periodically updated approximately on a three-year cycle. The most recent update, the 2013 Building Energy Efficiency Standards, goes into effect on July 1, 2014.

Effective Date: Title 24, Part 6, v2013 becomes effective on January 1st, 2014
