A Zero-Combustion Energy Facility

Our team’s geothermal design for Princeton University’s historic west campus and new east campus included providing analysis of infrastructure, university energy, economic, and environmental impact policies, and predictive modeling to establish a basis for infrastructure conversion and expansion projects that will reduce greenhouse gas emissions. Upon completion in 2022, the new greenfield TIGER (Thermally Integrated Geo-Exchange Resource) facility on the east campus will provide 6,800 tons of cooling and 113,600 MBH heating capacity solely from a geothermal system of 995 bores at a depth of 850 feet, augmented with two 2.25 million gallon thermal energy storage tanks (19,680 ton-hours cooling; 423,000 MBH heating). These measures will substantially advance Princeton toward its 2046 carbon neutrality target date—the school’s 300th anniversary.
