In FY 2010, EPA continued its long-term commitment to energy conservation and exceeded the federal energy reduction requirements set forth by the Energy Independence and Security Act of 2007 (EISA) and Executive Order (EO) 13423, which EO 13514 ensures are still in effect.

EPA reduced its energy intensity from 388,561 British thermal units per gross square foot (Btu/GSF) in FY 2003 to 317,577 Btu/GSF in FY 2010, exceeding the EO 13423 goal of 330,277 Btu/GSF without counting any of the Agency’s extensive green power purchases. This reduction represented an 18.3 percent energy intensity savings compared to the FY 2003 baseline established by EO 13423. EPA remains ahead of schedule in meeting annual energy intensity reduction goals thanks to a combination of recommissioning, facility upgrades, operations and maintenance improvements, and green power purchases.

EPA tracks its energy and water consumption quarterly in order to set priorities for energy assessments, mechanical system design and construction projects, and recommissioning efforts. EPA distributes this data in a variety of quarterly reports to EPA facility managers in an effort to motivate them to continue to conserve energy and water. Below are several data tables and charts representing year-end FY 2010 energy data.

To help stimulate the green power market, EO 13123 and the Energy Policy Act of 2005 (EPAct 2005) have historically allowed federal agencies to subtract, or “net out,” renewable energy purchases from total energy consumption figures in order to meet their mandated energy intensity reduction requirements. Under follow-up guidance related to EPAct 2005 and EO 13423, beginning in FY 2008 the U.S. Department of Energy has limited federal agencies’ use of renewable energy purchases to meet energy efficiency requirements. While purchases of green power and renewable energy certificates (RECs) may contribute up to 20 percent of an agency’s annual energy reduction goal for FY 2010, this percentage will gradually be reduced to zero by FY 2012.

FY 2010 Results

Agencywide Energy Consumption and Intensity Data Tables
These tables compare EPA's total Agencywide FY 2010 reportable energy consumption (Btu) and energy intensity (Btu/GSF) to EPA’s FY 2003 baseline figures, with and without green power purchases netted out.

Individual EPA Laboratories' Comparison of Energy Intensity in FY 2010 to FY 2003 Baseline
This chart compares individual EPA facilities’ energy intensity (Btu/GSF) in FY 2010 to their respective baseline energy intensity in FY 2003. Green power purchases are not netted out in this chart.

Individual EPA Laboratories' Share of Total Energy Use in FY 2010
This pie chart shows the percent share of EPA’s total Agencywide FY 2010 energy use associated with each EPA reporting facility. Green power purchases are not netted out in this chart.

Individual EPA Laboratories' FY 2010 Energy Cost in Dollars per GSF
This chart illustrates the FY 2010 energy cost for each EPA reporting facility (in dollars per GSF). EPA tracks utility cost data to help identify energy conservation projects that have exceptionally good payback potential. Investments in these projects provide economic benefits to the taxpayers by reducing future utility expenses and avoiding future energy cost increases.
