ABSTRACT The 2005 Energy Policy Act Requires that federal facilities be built to achieve at least a 30% energy savings over the 2004 ASHRAE Standard 90.1-2004. The Construction Engineering Research Laboratory of the U.S. Army Corps of Engineers@ in collaboration with U.S. Army Corps of Engineers Headquarters and centers of standardization for respective building types@ the U.S. Department of Energy (DOE)@ the National Renewable Energy Laboratory@ and the ASHRAE Military Technology Group have developed design guides to achieve 30% energy savings over a baseline 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 included barracks@ administrative buildings (e.g.@ a battalion headquarters and a company operation facility)@ 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 tactical equipment maintenance facilities (TEMFs). It provides a definition of the baseline building selected for the analysis and the modeling assumptions. As a result of a computer analysis using EnergyPlus version 2.0@ baseline and target energy budgets are clearly defined for all 15 DOE climate zones. Finally@ a recommended set of energy efficiency solutions for each climate zone is presented that enable at least 30% energy savings in addition to improved and more productive work environments that provide better thermal conditions and indoor air quality for soldiers and workers. Results of this study were implemented through the Army's standard design/build process in late 2007 by incorporating the target energy budgets by climate zone and the recommended sets of technologies to meet these budgets into the Army standard Request for Proposal for TEMFs.
