When Medfield became a green community last year, DOER gave the town a $148K grant to spend on energy reduction projects. The Medfield Energy Committee, with Facilities Manger, Jerry McCarty’s lead, identified exterior lighting upgrades (to LED’s) at the schools as a good solution to spend some of that grant money.
The MEC just circulated the RISE Engineering analysis of costs and benefits. Total cost is $118K, Eversource incentive money is $52K, so net cost to town is $65K. The lighting upgrades are all at schools, and four of five involve ROI pay backs of less than two years (the smallest $7K project at Wheelock had a six year pay back, but still a 16% annual ROI).
Jerry is also looking to upgrade the HVAC controls at both the Medfield High School and Blake Middle School as well.
