Bryan Gauger summarizes the major points from the new Title 24 code which will become effective January 1, 2014:
Title-24, California’s energy code in part governing energy efficiency of installed lighting, is changing effective January 1, 2014. I have prepared the linked pdf below highlighting the major changes to the interior lighting code and how space design and installation will change to accommodate the new code. Some of the revisions are dramatic and this will directly affect every project’s design and budget.
You can find the code and the compliance manual here at the California Energy Commission’s website : energy.ca.gov
