Results and Projections
In This Section
In FY 2008, 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 (E.O.) 13423. The Agency achieved a significant decline in reportable energy intensity at its reporting facilities in FY 2008 through a combination of recommissioning, facility upgrades, operations and maintenance improvements, and green power purchases.
In FY 2008, EPA reduced its energy intensity 3.2 percent compared to FY 2007. Compared to the FY 2003 baseline established by E.O. 13423, EPA reduced its energy intensity 17.5 percent, without netting out green power purchases1. EPA reduced its energy intensity in British thermal units per gross square foot (Btu/GSF) from 395,520 Btu/GSF in FY 2003 to 326,230 Btu/GSF in FY 2008, exceeding the E.O. 13423 goal of 359,923 Btu/GSF without counting any of the Agency’s extensive green power purchases.
EPA tracks its energy and water consumption quarterly in order to set priorities for energy audits, 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 2008 energy data.
To help stimulate the green power market, E.O. 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 reduction requirements. Under follow-up guidance related to EPAct 2005 and E.O. 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 renewable energy or renewable energy certificates (RECs) may contribute up to 60 percent of an agency’s annual energy reduction goal for FY 2008, this percentage will gradually be reduced to zero by 2012.
1 Note: Although EPA has been able to refine its FY 2008 data since it submitted its FY 2008 Annual Report to the U.S. Department of Energy (DOE), tables and charts on this Web site showing Agencywide performance are based on data that the Agency reported to DOE.
FY 2008 Results
Agencywide Energy Consumption and Intensity Data Tables
These tables compare EPA's total Agencywide FY 2008 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' Net Energy Intensity Impacts for FY 2008
This chart describes the impact of green power purchases, energy conservation projects, and recommissioning on individual EPA facilities’ net energy intensity (Btu/GSF) during FY 2008. While EPA's energy conservation efforts chiefly focus on the Agency's largest laboratories, no EPA laboratory is excluded from consideration for energy upgrades or green power purchases. Energy-intensive laboratories are another focus of EPA's energy conservation efforts. When large laboratories are also energy-intensive, significant opportunities for energy conservation exist.
Individual EPA Laboratories' Comparison of Energy Intensity in FY 2008 to FY 2003 Baseline
This chart compares individual EPA facilities’ energy intensity (Btu/GSF) in FY 2008 to their respective baseline energy intensity in FY 2003 to FY 2006. Green power purchases are not netted out in this chart.
Individual EPA Laboratories' Share of Total Energy Use in FY 2008
This pie chart shows the percent share of EPA’s total Agencywide FY 2008 energy use associated with each EPA reporting facility. Green power purchases are not netted out in this chart.
Individual EPA Laboratories' FY 2008 Energy Cost in Dollars Per GSF
This chart illustrates the FY 2008 energy cost for each EPA reporting facility (in dollars per GSF). EPA tracks operating cost data to help identify energy projects that have exceptionally good payback potential. Investments in energy conservation projects provide economic benefits to the taxpayers by reducing future utility expenses and avoiding future energy cost increases.
Future Projections
Individual EPA Laboratories' Projected FY 2009 Energy Intensity
This bar chart shows projected energy intensity (Btu/GSF) for EPA’s individual reporting laboratories for FY 2009. Green power purchases are not netted out in this chart.
Agencywide Projected Annual Energy Intensity, FY 2003-2015
This line graph shows EPA's Agencywide energy intensity (Btu/GSF) for reporting laboratories from FY 2003 through FY 2008, and projections through FY 2015, compared to EPAct 2005, E.O. 13423, and EISA energy reduction goals. Green power purchases are not netted out in this chart.
