Cornell cools campus with 39°F water from 250 ft below Cayuga Lake, cuts energy 85%
Launched in 2000, Cornell University's lake source cooling system exemplifies sustainable innovation, utilizing the icy waters of Cayuga Lake to meet the campus's cooling demands. This groundbreaking initiative, which commenced construction in 1999, achieved an extraordinary eighty-five percent cut in annual energy consumption, positioning the university at the forefront of eco-friendly solutions…
Cornell University, a prestigious institution overlooking Cayuga Lake, has drastically reduced its energy consumption by harnessing the cool waters of the lake. In the late 1980s and early 1990s, the university, like many others, relied on harmful CFC chillers that depleted the ozone layer. Due to these environmental concerns and regulatory changes, Cornell transitioned to a lake source cooling (LSC) system.
This innovative technology utilizes the consistently cold, deep waters of Cayuga Lake to cool the campus, achieving an impressive 85% reduction in energy usage for campus cooling. By transferring heat from the campus chilled water to the lake water through heat exchangers, the system maintains separate loops for the lake water and campus water without any mixing.
The deep waters of Cayuga Lake provide a renewable source of chill, saving up to 85% of the energy needed for conventional cooling methods. Since its implementation in 2000, Cornell's LSC system has earned accolades for its sustainable energy solutions, saving over 29 million kWh annually and making up 98% of the cooling on the campus as of 2008.
