Existing Buildings Tool Kit

California's Green Building Initiative (Executive Order S-20-04) requires all state buildings larger than 50,000 square feet to maintain a Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) certification of silver or greater. There are approximately 210 buildings statewide that are required to be maintained and operated according to the US Green Building Council's rating system that outlines sustainable practices in sustainable sites; water efficiency; energy and atmosphere; materials and resources; and indoor environmental quality.

Led by the CA Department of General Services, the Statewide LEED-EB Workgroup is a core group gathered from 18 departments/agencies that are responsible for the facility management of the state of California's larger public buildings. The workgroup was formed in February of 2008 and provides opportunities to share information about "greening" state facilities and receive training for attaining LEED-EB certification at state facilities.

The DGS has developed several tools available to interested public and private entities to assist in understanding LEED-EB documentation and sustainable activities:
