Lake Source Cooling

The Lake Source Cooling (LSC) project is one of the most significant energy initiatives ever undertaken by an American university in order to promote sustainability. 

Beginning in July of 2000, after a 4-year application review process by the New York Department of Environmental Conservation (DEC), LSC is an environmentally sustainable upgrade to the chilled water system on campus, conserving energy by utilizing the cold waters of Cayuga Lake.

This method of cooling eliminates the need for refrigeration equipment, significantly reducing Cornell’s reliance on fossil fuels by using approximately 85% less energy. Furthermore, not only is LSC much more cost effective, there is also greater reliability and benefits for the environment in the long run. Because the system needs no refrigerants and is so efficient, it significantly reduces the greenhouse gas emissions typically associated with large cooling systems. In accordance with DEC requirements, Cornell also included several features in the construction and operation of the LSC project to further minimize any potential impacts.
