Cooling Cornell. Decision nears on cooling plan.
The Ithaca Journal, Jun 6 1998, P. 5, full page, with many diagrams

"In 1994, Cornell engineers proposed cooling the campus using water drawn from deep in Cayuga Lake.
  If constructed, the project would cool the central campus using about 80 percent less energy than traditional air conditioning. The energy savings would power 2,000 homes a year, according to the recently released Draft Environmental Impact Statement (DEIS) on the project."

"Present vs. proposed
  At a cost of $55 million, the Lake Source Cooling project entails building a 14,000-square-foot chilled water plant at 983 East Shore Drive and installing piping uphill from East Shore Drive and along Ithaca City School District property.
  The plant would draw cold water from about 250 feet deep in the lake and run it alongside warm water pumped down from Cornell to a heat exchange facility near the lake's east shore.
  There, the lake water - drawn in at between 10,000 and 30,000 gallons per minute — would cool the Cornell water. No water from Cornell would mix with lake water or enter the lake through the cooling system. The newly chilled water from Cornell would be pumped back up to campus to cool buildings and equipment while the lake water would circulate back into the lake."
