And an excerpt from the site:

The Energy Efficiency Standards for Residential and Nonresidential Buildings were established in 1978 in response to a legislative mandate to reduce California’s energy consumption. The standards are updated periodically to allow consideration and possible incorporation of new energy efficiency technologies and methods.

You can view the 2005 standards here in PDF form:

California’s building efficiency standards (along with those for energy efficient appliances) have saved more than $56 billion in electricity and natural gas costs since 1978. It is estimated the standards will save an additional $23 billion by 2013.

The current 2005 standards and the 2001 Standards may be downloaded from the Web pages listed above, or to obtain a hard copy, contact the Energy Commission’s publications unit at 916-654-5200.
