State Building Energy Consumption

All state-owned government buildings in California have been benchmarked for energy use by employing the energy management tool, U.S. EPA Energy Star Portfolio Manager. 

Benchmarking is the measurement and tracking of energy use by facilities. Energy Star is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy for consumers and organizations pursuing energy efficiency improvements.

Major utilities have completed linking utility accounts to the Energy Star Portfolio Manager database and are uploading utility data on a monthly basis. DGS continues working with state agencies to resolve data issues and to assist agencies in collecting, updating and verifying benchmarking data.

In 2010, DGS completed benchmarking for 1,718 state facilities. Data indicated that although the state building area grew by 8.7 percent between 2003 and 2010, overall energy use increased by only 1.8 percent during that same time period, while energy use intensity (energy used per square foot of building area) was reduced by 6.3 percent.
