The Lake Source Cooling (LSC) project is one of the most significant energy initiatives undertaken by an American university to promote sustainability.  Started 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 campus’ chilled water system, conserving energy by utilizing the cold waters of Cayuga Lake.  This method of cooling eliminates refrigeration equipment and the environmental degradation associated with it, and has significantly lessened the campus’ reliance on fossil fuels.  In addition to being significantly more cost effective, LSC is much more reliable and environmentally beneficial in the long run.  In accordance with the DEC’s requirements Cornell also included many special features in the construction and operation of the LSC project to further minimize any potential impacts, and carries out a lake-monitoring program to ensure its safe operation on the lake.   Participants in the project include our University, the City of Ithaca, and the Ithaca School District.
