California State Central Plant Bridging Documents and Peer Review

Sacramento, CA

The State of California Central Plant was originally constructed in the late 1960s. After fifty years of supplying heating and cooling to 23 buildings in the Downtown Sacramento area, including the State Capitol, the Central Plant was in need of a major overhaul. The Bridging Document team was charged with developing a strategy to replace the antiquated equipment, increase the capacity, include emergency power generation capabilities and eliminating the discharge of water into the Sacramento River and do it all while the original plant remained fully operational. The new LEED Gold Central Plant with LEED Platinum administrative areas achieved all of these goals.
