2008 Building Energy Efficiency Standards (Title 24, Part 6 of California Code of Regulations)
Intro/Brief:
- Residential Code: 2008 Building Energy Efficiency Standards (BEES), Title 24, Part 6 of the California Code of Regulations -- This state-developed code meets or exceeds the stringency of the 2009 IECC and is mandatory statewide.
-
Commercial Code: 2008 Building Energy Efficiency Standards (BEES), Title 24, Part 6 of the California Code of Regulations -- This state-developed code meets or exceeds the stringency of the ASHRAE Standard 90.1-2007 and is mandatory statewide.
The California Energy Commission (CEC) completed the rulemaking process for the 2008 Energy Efficiency Standards for Residential and Nonresidential Buildings. The CEC adopted the 2008 Standards on April 23, 2008, and the Building Standards Commission approved them for publication on September 11, 2008. Though initially slated for implementation on August 1, 2009, the 2008 Standards became effective on January 1, 2010.
The CEC has also posted the final versions of the 2008 Residential Compliance Manual and the 2008 Nonresidential Compliance Manual.
A first analysis of the 2008 Standards revealed an average energy performance at least 21% more efficient than ASHRAE 90.1-2004.
