Zero Carbon Building
The Reuse Center building at Boston Building Resources has been certified as zero energy by the International Living Future Institute (ILFI), representing one of the highest aspirations in energy performance for buildings. All the energy needed to heat, cool, and light the building on an annual basis is produced through a carbon-free renewable source—namely, an array of 114 rooftop solar panels (46 kilowatts). All-electric HVAC equipment provides heating and cooling, and a well-insulated building envelope (5-inch R-38 roof, 4-inch R-31 walls) keeps the conditioned air in. An electric vehicle charger in the parking lot is also powered by the rooftop solar array. Lighting fixtures are efficient LEDs.
