The mission of the U.S. Department of Energy's Federal Energy Management Program (FEMP) is to reduce the cost of Government by advancing energy efficiency, water conservation, and the use of solar and other renewable technologies. This is accomplished by creating partnerships, leveraging resources, transferring technology, and providing training and technical guidance and assistance to Federal agencies. Each of these activities is directly related to achieving the requirements set forth in the Energy Policy Act of 1992 and the goals that have been established in Executive Order 13123 (June 1999), as well as supporting activities that promote sound management of Federal financial and personnel resources. The Pacific Northwest National Laboratory (PNNL) supports the FEMP mission in all activity areas. This document provides information that will be useful to FEMP in targeting and identifying Federal sites for energy efficiency project potential. This document consolidates Federal energy data into a single source reference from which FEMP that can work to more efficiently target opportunities. It is hoped that this will ultimately assist in the development and implementation of more Federal sector energy efficiency projects financed with private sector capital.
