Energy Efficiency Upgrades in City Buildings
If you happen to visit a City or school building in Cambridge these days you may notice classrooms, hallways and offices looking a lot brighter. That is because thirteen City buildings have received $1.1 million in energy efficiency improvements, thanks to federal stimulus grants, NSTAR rebates and City funding.
City contractors have installed high efficiency lighting and occupancy sensors at Cambridge City Hall, Area 4, Frisoli and Gately Youth Centers, the main Senior Center, Engine 3 (East Cambridge) and the Baldwin, Haggerty, Kennedy and Peabody Schools. The new lights use 20% to 50% less electricity than the old ones, and occupancy sensors, installed where appropriate, add to the savings by turning off lights when rooms are vacant. Rooms are also brighter, due to both the color of the new lamps and because output from old bulbs decreases over the years.
“We thank the federal government and NSTAR Corporation for supporting the City’s commitment to energy efficiency”, said City Manager Robert Healy. “The new lighting and heating systems will save energy, save money and make our buildings more comfortable to work, learn and do city business.”
Contractors are also installing high-efficiency condensing boilers at the Longfellow School, Moore Youth Center and Frazier Public Works Administration building. The new boilers are replacing inefficient and failing equipment.
Altogether, these projects are expected to save 760,000 kilowatt hours of electricity and 20,000 therms of natural gas per year. This will prevent 500 tons of CO2 from being released into the atmosphere each year, and is enough energy to light 65 homes for a year.
