Princeton University Geo-Exchange Plants and Garage

Princeton University’s Parking and Geo-Exchange Facilities, part of the University’s Net-Zero program, are stunning examples of sustainable innovation and design. The garage’s undulating mesh façade is lit by concealed uplights, creating a dynamic reversal of daytime lights and shadows. A glowing stair-tower and uplit canopy enhance the garage’s visual appeal and minimize light pollution, while interior integrated lines of light serve as cues for public circulation.

The two Geo-Exchange Facilities make the “exchange” element of the system visible from outside by intention with glass exposures. At night, the main entry of the Geo-Exchange plant glows from a concealed grazer highlighting the wood façade while strategically located uplights highlight the clerestory window allowing the perimeter soffit to capture the light and avoid light pollution. The designs showcase the Geo-Exchange systems, blending functionality with striking architecture to spark curiosity about what is inside. Each building operates quietly, emitting no smoke or steam.
