Energy performance optimization for Army installations

Buildings contribute to a large fraction of energy usage worldwide. In the United States alone, buildings consume about 40% of total energy expenditure, including 71% of electricity and 54% of natural gas.1 The Army alone spends more than US $1 billion for building-related energy expenses. The 2005 Energy Policy Act2 requires that Federal facilities be built to achieve at least a 30% energy savings over the 2004 International Energy Code or ASHRAE Standard 90.1-2004, as appropriate, and that energy efficient designs must be life-cycle cost effective. According to the Energy Independence and Security Act (EISA 2007),3 new buildings and buildings undergoing major renovations shall be designed to reduce consumption of energy generated off-site or on-site using fossil fuels, as compared with such energy consumption by a similar building in fiscal year 2003 (FY03) as measured by Commercial Buildings Energy Consumption Survey (CBECS) or Residential Energy Consumption Survey (RECS) data from the Energy Informati...
