GSA's ARRA-Funded Green Investments Help Albany Federal Building Weather the Storm
November 6, 2014
WASHINGTON – Today, the U.S. General Services Administration (GSA) announced that its American Recovery and Reinvestment Act-funded green investments are helping federal buildings, like the Leo W. O’Brien Federal Building in Albany, NY, use less energy, even during harsh winters. After analyzing the energy usage data of 59 federal buildings in states that were hardest hit by this past winter, GSA found that these buildings, all of which received ARRA-funded green investments, used an average of 5.5 percent less energy compared to the winter before the projects began. These buildings saved enough energy during the winter months to supply 640 U.S. homes with electricity for a full year. In addition, a third of these buildings showed double-digit energy savings.
Ruth Cox, GSA’s Senior Sustainability Official, said:
“Even during frigid temperatures and record snowfalls, GSA’s ARRA-funded green investments are helping make federal buildings more energy efficient. As the frequency of extreme weather events trends upward, it is important that federal buildings are able to meet the needs of occupants while also being cost-effective to operate.”
Denise L. Pease, Regional Administrator, GSA’s Northeast and Caribbean Region, said:
“These energy savings, that are the result of ARRA-funded upgrades at the O’Brien Federal Building in Albany, are just an example of the many green initiatives GSA is exploring all across our region and nation that will save energy and tax dollars.”
Harsh Winter Analysis
Building: Leo W. O’Brien Federal Building
Completion Year: FY 2012
Winter Energy Cost Savings: $19,000
Winter Energy Reduction: 12.4%
Full-Year Energy Cost Savings: $60,398
Full-Year Energy Reduction: 20.5%
At the Leo W. O’Brien Federal Building in Albany, N.Y., GSA used ARRA funds to invest in a complete re-commissioning of the existing heating, ventilation, and air conditioning system (HVAC), as well as an advanced metering system to track electrical and water consumption. These building upgrades help optimize energy efficiency and overall building performance levels. Additional case studies can be found here.
• Building Set: The building set was made up of 59 buildings located in cities that experienced harsh winters, and received ARRA-funded green investments completed before November 2012.
• Harsh Winter: Cities home to GSA buildings that had an average monthly temperature of at least three degrees below the normal monthly average, or had a month with at least five heating degree days more than average during the FY 2014 Winter (November 2013 – March 2014) met the definition of “harsh winter”. The definition applied to the District of Columbia, and cities in the following seven states: Georgia, Illinois, Maryland, Massachusetts, Missouri, New York, and Pennsylvania.
• Energy Usage Intensity: The average energy usage intensity (EUI) of the 59 buildings was 5.5 percent lower over the harsh winter months in FY 2014 as compared to the same months in FY 2008. Of the 59 buildings analyzed, 20 reduced their winter energy usage intensity by 10 percent or more between FY 2008 and FY 2014. EUI is calculated by dividing total energy usage (i.e. chilled water, gas, electricity, steam, oil) by total number of square feet.
• Baseline Year: The FY 2008 winter (November 2007-March 2008) was used as the baseline because it was the last winter before the ARRA projects began. Normal weather conditions are based on NOAA’s 1981-2010 observed average temperatures.
About GSA’s ARRA-Funded Projects
The Recovery Act allocated funds for GSA to convert federal facilities into high-performance green buildings, and to address deferred maintenance needs and necessary facility upgrades. GSA has 447 federal buildings with completed or ongoing ARRA-funded projects. These projects are expected to reduce energy consumption by 19 percent and yield annual energy cost savings of $62 million once all are complete.
