In 1998 the College developed a central chilled water plant to address the majority of the campus’ cooling needs. Where possible, buildings are designed to connect into central utility systems to take advantage of the load diversity. The central systems are almost always more efficient than individual distributed systems (which was the College’s design strategy before 1998).
Central Chilled Water Plant: .8 kW/ton
Unitary Air Conditioner: 1.2-1.4 kW/ton
