Energy Design Guides for Army Barracks
The Energy Policy Act of 2005 requires federal facilities to be built to achieve 30% energy savings over the 2004 International Energy Code or American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1-2004, as appropriate. The Engineer Research and Development Center of the U.S. Army Corps of Engineers and the National Renewable Energy Laboratory (NREL) are developing target energy budgets and design guides with a prescriptive path to achieve 30% energy savings over a baseline built to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004. This project covers eight building types in 15 U.S. climate zones. The building types include barracks, administrative buildings, a maintenance facility, a dining facility, a child development center, and an Army reserve center. All the design guides will be completed by the end of 2008. This paper focuses on the design guide for one type of barracks called unaccompanied enlisted personal housing (UEPH). The UEPH buildings are similar to apartment buildings with double occupancy units. For each building type, a baseline was established following typical Army construction and ASHRAE Standard 90.1 Appendix G modeling rules. Improvements in energy performance were achieved for the envelope using the NREL optimization platform for commercial buildings and previous ASHRAE design guides. Credit was also taken for tightening the building envelope by using proposed envelope leakage rates from ASHRAE and the Army. Two HVAC systems, including a dedicated outdoor air system, were considered. The final results achieved 29% site energy savings in two climates and greater than 30% site energy savings in all other climates. Results of this study were implemented in the Army's standard RFP process for new UEPH barracks construction in late 2007. New UEPH design/construction begun in 2008 and beyond will require the contractor to design and construct a UEPH facility that meets the target energy budget developed in this study using either a custom design or the design guide's prescriptive path developed as part of this study.
