The resource center includes the CALGreen Companion Guide for LEED Projects, which provides recommendations for reducing the documentation burden on LEED-NC commercial projects that must meet the California Green Building Standards Code (CALGreen) non-residential mandatory provisions. The Companion Guide is intended for building officials as well as design professionals. This Companion Guide does not address the voluntary “Tiers” in CALGreen, nor does it address residential CALGreen mandatory code requirements.
