From John Britton, AIA:
"The effective date for the 2008 Building Energy Efficiency Standards (Title 24, Parts 1 and 6) has been changed to January 1, 2010.
The California Energy Commission adopted the 2008 Standards on April 23, 2008, and the Building Standards Commission approved them on September 11, 2008. The Standards were scheduled to become effective on August 1, 2009.
The Energy Commission has experienced delays in completing the public domain compliance software. The Energy Commission had anticipated that these software programs would be available earlier, however the software required further programming attention before the programs could be released. The Energy Commission is resolving those problems, and will provide the programs in the near future.
This delay provides the industry and building officials more time to prepare for the new Standards. The Energy Commission will use this additional time to provide more information for the Standards and work with the California utilities, building industry and the California Building Officials to provide training on the new Standards."
