Name or title of the innovative policy, practice, program, or outcome:
Cooling a Particle Accelerator using Only Lake Water

A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:
The Wilson Laboratory at Cornell University has upgraded its cooling system for the Cornell High Energy Synchrotron Source (CHESS). The lab now utilizes Cornell's Lake Source Cooling (LSC) system, drawing cold water from Cayuga Lake to remove heat from the district chilled water loop that cools the majority of Cornell facilities. This switch enhances efficiency, sustainability, and allows year-round operation, being over six times more efficient than traditional water chilling systems. Overall, this initiative is expected to save 4 million gallons of water and $50,000 in electricity costs annually while providing over 1,000 researchers more access to research during the summer. https://news.cornell.edu/stories/2023/09/lake-source-cooling-brings-sustainability-precision-synchrotron More info about Lake Source Cooling can be found here: https://fcs.cornell.edu/departments/energy-sustainability/utilities/cooling-home/cooling-production-home/lake-source-cooling-home/how-lake-source-cooling-works
