The University recently completed an energy retrofit in 51 of its campus buildings, which realized a 25 percent reduction in energy use among those buildings. Web-based electricity metering and steam plant condensate metering are used to identify buildings that are large power consumers, to gauge the effectiveness of conservation measures on a building-by-building basis, and to identify leaks in the system. Econo Cool technology, estimated to be 50 percent more energy efficient than traditional technologies, is utilized in all new refrigerated vending machines. Ninety solar panels were installed on the Curry Student Center with an output of 22 kilowatts, supplying electricity to the student center and preventing 13.5 tons of carbon dioxide from being produced by electric generation using fossil fuels. The University purchases Energy Star-certified appliances and computers, and uses compact florescent lamps. In one year, the University purchased 20 electric golf carts as an alternative transportation solution for use by facilities, athletics, and others, reducing vehicular traffic on campus.
