Energy Optimization Assessment at U.S. Army Installations: Fort Bliss, TX

An Energy Optimization Assessment was conducted at Fort Bliss as a part of the Annex 46 Holistic Assessment Toolkit on Energy Efficient Retrofit Measures for Government Buildings (EnERGo) initiative to identify energy inefficiencies and wastes and propose energy related projects with applicable funding and execution methods that could enable the installation to better meet the energy reduction requirements mandated by Executive Order 13123 and Energy Policy Act (EPAct) 2005. The assessment included a Level I study of energy conservation opportunities in a number of representative buildings including an analysis of their building envelopes, ventilation air systems, controls, interior and exterior lighting as well as opportunities to use renewable energy resources. The Annex 46 initiative at Fort Bliss did not include the evaluation of industrial or manufacturing processes. The study identified 210 different energy conservation measures (ECMs) that if implemented would reduce Fort Bliss's annual energy use by up to 65 MWH/yr electric and 170,023 MMBtu/yr thermal savings (mostly natural gas). Savings of $552K/yr in maintenance costs were also identified. The total energy and maintenance savings would be $7.9 million/yr. An investment of $23.4 million to implement the ECMs results in a simple payback of 3 yrs. These ECMs are presented in nine groups according to the system type that the ECM affects.
