(Olympia, Wash.) The Evergreen State College will receive a grant from Puget Sound Energy for $137,500 shortly after 10:00 a.m. at its regular Board of Trustees Meeting on January 14, 2009.
The grant will help defray the cost of variable speed drives that reduce the energy used by the two chillers that provide chilled water for air conditioning at Evergreen. The drive works by varying the speed at which the chiller runs depending on the amount of chilled water needed for the air conditioning load. The proposed chilled water system with variable speed drives has the potential for 27 percent or 226,442 kilowatt hours per year savings over the previous system.
In 2008, PSE provided more than $18 million in conservation and energy efficiency grants to businesses and organizations in their service area. The Evergreen State College has been a partner in PSE’s green energy program since October 2005.
