The efforts of the Air Force to reduce energy consumption are driven largely by external goals and mandates derived from congressional legislation—the Energy Policy Act of 2005 (EPACT) (Public Law No. 109-58) and the Energy Independence and Security Act of 2007 (EISA) (Public Law No. 110-140)—and Executive Order 13423 (EOs), shown in Figure 1-3. To date, these goals and mandates have targeted the energy used in facilities only and not the larger amount used in aviation operations. The primary metric used in setting the goals is energy intensity, as measured in British thermal units (Btu) per square foot of facility space. The goal for facility energy is an intensity reduction of 3 percent per year from 2003 to 2015. The Air Force has made considerable progress toward its goals, having invested hundreds of millions of dollars ($274 million in FY 2011) in projects that have reduced facility energy intensity by 16 percent since the base
