GSA sees $48k savings by installing more efficient HVAC system
The U.S. General Services Administration, landlord for the federal government, is committed to energy conservation across its real estate portfolio. GSA’s Mid-Atlantic Region upgraded chillers, cooling fans and pumps at the William J. Green, Jr. Federal Building in Philadelphia. Since 2018, GSA has reduced energy consumption at the Green Federal Building by 20% through operational vigilance and use of smart building technology, and received a $48K rebate from PECO Energy in late March 2021.
“This rebate is just one result of GSA’s dedication to reducing energy consumption,” stated Joanna Rosato, Acting Regional Administrator. “Whether it’s more efficient building operations, sustainable materials or waste reduction, we remain committed to a greener federal footprint while providing value and savings to the taxpayer.”
In 2018, the outdated chillers were replaced with new variable speed drive units which analyze information from sensors located throughout the system and adjust operational settings in real time. Similarly, the condenser, chiller pumps and cooling tower fans were replaced with variable speed units, allowing the pumps to run at less than 100% capacity, saving energy by reducing the flow requirements.
These savings are comparable to removing 1,200 passenger vehicles from the road each year.
Construction and equipment data, as well as Building Automation Systems logs, were shared with PECO to create an Energy Saver Profile, resulting in the rebate for energy savings.
