The burning question everyone is asking: “What is the difference between the new California Building Code (CALGreen) and third party rating systems?”  GOOD NEWS – a very handy and thorough comparison chart has arrived!

The USGBC-NCC, along with AIA California Council, AIA-SF, StopWaste, City of San Francisco, Simon and Associates, and Build it Green formed the Green Building Codes Educational Collaborative.  This group created two matrixes (one for commercial space and one for residential space) as quick reference guides to compare CALGreen to third party systems.  The matrixes are as compact as one could hope.

The commercial matrix compares CALGreen (Commercial) with LEED BD+C.  The residential matrix compares CALGreen (residential) with (GreenPoint) Build it Green and LEED for Homes.

Please click below for the complete packet I just received Friday from the USGBC-NCC.  If you like the content of these documents, please consider a membership with at least one of the groups that helped make the documents possible.
