California Department of Education HQ - Block 225: Sacramento, CA
The California Department of Education Headquarters, built in 2002, raised the bar for sustainable building practices in California. It is the first state office building to incorporate an underfloor air-distribution system and is the state's first design-build office building. Sustainable practices used during construction are now part of the state's green building manual. At least 25% of the building includes recycled materials, including the lobby marble flooring, which was salvaged from the Library & Courts Building, circa 1923.
