13 Dummerston Energy Committee What’s Next? a Collecting ‘Baseline’ Data to meet the Town Plan The Energy Committee is planning a survey to be sent out to Dummerston Residents to collect more detailed data about their energy use, type of fuels used, and more! Please take the time to fill it out and send it back. The data becomes knowledge. That knowledge will help us chart the Dummerston energy future.
14 Dummerston Energy Committee What’s Next? a Upgrading Street lights to LED Total anticipated fixture upgrades: 22 Old fixtures: 100W Mercury Vapor (MV) Now banned by federal law 2200W x 12hrs/night= 9636 Kwh per year New Fixtures: 20-LED, 37W Cost of Tariff is similar to MV Tarriff 814W x 12hrs/night= 3565Kwh per year Annual energy savings: = 6070 KWH CO 2 eliminated: 5631 pounds annually
15 Dummerston Energy Committee a School Gym Lighting Upgrade Total upgraded fixtures: 20 Old fixtures: 400W Metal Halide = 8000W total New Fixtures: 4-lamp 54W fluorescent T-5 (216W each) = 4320 W Annual energy savings: 3.68 KW x 1760 Hours = 6477 KWH Cost Savings at $ 0.09 / KWH: 6477 x 0.09 = $583 / annually We expect the energy savings to be significantly more as the actual usage may be cut by a third to one-half of previous usage: The old lights took so long to turn on that it was impractical to turn them off during the day The new lights are controlled by motion sensors to automatically shut off when not needed
16 Dummerston Energy Committee Whats Next? a School Outdoor Lighting Upgrade Currently the 30 fixtures around the school are older less efficient technologies that are on ALL night, EVERY night.
