The Building Energy Efficiency Standards serve to reduce wasteful, uneconomical, and unnecessary uses of energy for the state. They include requirements in the Energy Code (Title 24, Part 6) and voluntary energy efficiency provisions in CALGreen (Title 24, Part 11). The Building Energy Efficiency Standards are updated every three years.

They conserve nonrenewable resources, such as natural gas, and ensure renewable resources are extended as far as possible so power plants do not need to be built.
