The Bloomburg Center on Cornell’s new applied tech campus in New York City is one of the largest aspiring net-zero energy buildings in the US. The Ground Source Heat Pump system consists of 80 boreholes spaced 20 ft. apart, drilled to a depth of 400 ft. It provides the majority of the heating and cooling load for the building.
This system, the first of its kind in the United States, uses a unique annulus system to increase the efficiency of the ground loop. It takes advantage of river water penetration through the local bedrock which occurs at a major water-bearing fracture at between 300-380 ft., to accelerate thermal dissipation.
We seamlessly integrated with the General Contractor on the site, effortlessly managing the logistical complications that arise from working in a city-center location.
