This session consisted of a 3 segment presentation on the Princeton University TIGER Geo-Exchange Project. Princeton University, Burns & McDonnell, and Whiting-Turner will share the story of design, construction, and first year operating data on Princeton University's new geo-exchange utility resource. TIGER consists of nearly 600 geo-exchange bores, each 850 ft deep, and two 2.25 million gallon TES Tanks, connecting to a system supplying 3,400 tons of heating & cooling to campus. This is the beginning of the conversion that the University is tackling as part of their goal of carbon neutrality. Segments include "how we got here"/construction, commissioning & flushing, and "state of the TIGER" - a showcase of >1 year of active operating data.
