Use of Geothermal and Biofuels to Reach Net Zero in a Northern Public Transit Center

The Olver Transit Center in Greenfield, Massachusetts is the first net zero public transportation center, using geothermal heat pumps, a 7300 sq ft ground mounted PV system and an on-site wood pellet boiler. The geothermal and pellet boiler are supplemented by air preheating with a solar wall and energy heat recovery. It includes office space on the second floor and is designed to also serve future rail service.
