The California Energy Commission revised the effective date for the 2013 Building Energy Efficiency Standards (Title 24, Part 1, Chapter 10 and Part 6, and affected provisions in Part 11 [Cal. Green Building Standards Code]) from Jan. 1, 2014 to July 1, 2014. The public domain software for the 2013 Standards does not yet provide the full feature set needed for building and alteration projects seeking building permits in early 2014. Further, time is needed for the building industry and local building departments to learn and adapt to the new tools.
