University of Southern Maine Wishcamper Center

Geothermal System

Portland, Maine

The University of Southern Maine (USM) is aggressively pursuing a sustainable campus and development of sustainable facilities. This new three-story academic building incorporates a number of innovative green and sustainable ideas. These include daylight harvesting, demand-controlled ventilation, green roof, no on-site fossil fuels, and a geothermal heating and cooling system.

The geothermal system at USM’s Wishcamper Center is a standing-column type design. The system circulates ground water from deep bore wells to the building. The ground water is piped to individual water-to-water heat pumps that produce both chilled water and heating water for the building’s air-handling heating and cooling equipment.

This project achieved LEED Gold certification.
