Executive Order 13123 requires Federal agencies to reduce building energy consumption per square foot by 30% in 2005 and 35% in 2010, both relative to 1985. Since 1985, energy use at federal buildings has dropped from 139.8 MBtu/ksf (million Btu per thousand square feet) to 113.7 MBtu/ksf in 1998 [1]. Thus, significant additional energy savings will be required to meet the future goals of 97.9 MBtu/ksf in 2005 and 90.9 MBtu/ksf in 2010. This paper reports on the results of a study conducted by the Pacific Northwest National Laboratory for the U.S. Department of Energy?s (DOE?s) Federal Energy Management Program (FEMP) [2]. The study estimated the life-cycle cost-effective (i.e., economic) energy savings potential in federal buildings via retrofit of energy-related infrastructure and the corresponding capital investment required to achieve these savings, with federal financing. Estimates were developed for major categories of energy efficiency measures such as building envelope, heating systems, cooling systems, and lighting. The estimated potential was then compared with the requirements for meeting energy efficiency goals.
