Inquiry
Intent: To properly calculate the energy points available in EA credit 1.1 through 1.10 for connection to an innovative district cooling system in lieu of constructing an independent building cooling system. Background: Cornell University designed and built an innovative campus cooling system called Lake Source Cooling to replace an existing chiller-based central cooling system. Lake Source Cooling\'s pumping system cools the campus chilled water loop using a closed loop heat exchanger system with water withdrawn from the depths of Cayuga Lake, without refrigerants. The overall energy efficiency of this system is extremely high, requiring less than 10% of the electrical energy of a conventional cooling system. This system has won numerous awards for innovation and energy efficiency, including the following:
