GSA Energy Retrofit

For this project, Forrester Construction performed the design-build retrofit of the GSA Energy Retrofit of a regional federal office and data center that was formerly GSA’s largest energy consumer.  The General Services Administration (GSA) is an agency that oversees the management and operation of federal government offices.  As part of The American Recovery and Reinvestment Act, the occupied building received a new energy efficient infrastructure while maintaining 24/7 operations.

To reduce energy consumption, a 255 kW rooftop photovoltaic solar array, 140 well geothermal system and high-efficiency MEP systems were installed. The photovoltaic array is mounted on the roof and outdoor canopies that function as both covered walkways and additional space for solar panels. The building is heated and cooled by 500 foot deep geothermal wells which serve 13 ground source heat pumps. A renovated chiller provides supplemental support on peak days.

To minimize the impact of construction on the facility’s critical operations, Forrester developed solutions to perform the complex renovation with zero downtime.
