Value Delivered
ECM provided kitchen HVAC system upgrades in Predolin Humanities Center and Regina Hall at Edgewood College. Our team converted the constant air volume (CAV) kitchen hoods to variable air volume (VAV) and installed a new hood controls system from TEL.
Energy savings from the upgrades are projected at 50,759 kilowatt hours and 13,428 therms each year, for a total annual cost savings of $13,268. Incentives provided another $3,300, giving this project a simple payback of 3.7 years.
Client Objectives
Edgewood College had an energy conservation fund with strict technical and payback criteria. The project goals were to save energy, reduce noise levels, decrease grease entrapment, and reduce HVAC equipment wear.
