LO-09-095 -- Improving Energy Performance of Army Dining Facilities

The Energy Policy Act of 2005 requires that federal facilities be built to achieve at least 30% energy savings over ASHRAE Standard 90.1-2004. The Construction Engineering Research Laboratory of the U.S. Army Corps of Engineers, in collaboration with USACE HQ and centers of standardization for respective building types, the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL), and the ASHRAE MTG have developed design guides to achieve 30% energy savings over a baseline. This baseline was built to the minimum requirements of ASHRAE Standard 90.1-2004 for new buildings to be constructed under the Military Transformation Program. The building types include barracks, administrative buildings, a maintenance facility, a dining facility, a child development center, and an Army reserve center. This paper presents the results of the energy analysis for Dining facilities. It provides a definition of the baseline building and the modeling assumptions. EnergyPlus version 2.1 was used to determine baseline and target energy budgets for all 15 DOE climate zones. Finally, a recommended set of energy-efficient solutions for each climate zone is presented that enable at least 30% energy savings over the baseline. Results of this study were implemented through the Army’s standard bid-build process in late 2008 by incorporation in request for proposal target energy budgets by climate zone and sets of technologies to meet these budgets.
