Environmentally Safe Roof Systems
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 roofing systems technologies and methods.
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.
2001 Standards - These standards were in effect prior to the 2005 Standards. Projects that applied for building permits prior to October 1, 2005 fall under the 2001 Standards.
2008 Standards - The 2008 update process has begun. This page has the latest information.
The current 2005 standards and the 2001 Standards may be downloaded from the California Sate Web Site, or to obtain a hard copy, contact the Energy Commission's publications unit at 916-654-5200.
