Since its founding in 1891, The Hotchkiss School, a college preparatory boarding school seated on 810 wooded acres in Lakeville, Connecticut, has been educating the elite tiers of the American intelligentsia, and now, the campus’s new 16,500-square-foot biomass power plant serves to complement that mission and make it greener in the process—an estimated six million pounds of carbon dioxide per year greener, in fact.
Noted for its undulating green roof that converses aesthetically and practically with the rain gardens and bioswales on-site, the biomass plant—designed by Centerbrook Architects and Planners—burns 5,400 tons of wood chips per year, is the third LEED-certified power plant in the United States, and is one of only 80 such biomass plants in the country.
Power produced by the facility’s two Messersmith biomass boiler units, which operate at up to 82 percent efficiency, generate 14 million Btus per hour, use wood chips from FSC-certified forests, harvest waste ash to be used for fertilizer on the campus, and use an electrostatic precipitator to remove 95 percent of emitted particulate matter. It looks clean, and it burns clean.
GREEN
Certification LEED certified
Energy Replacing oil-fired boiler reduces greenhouse gasses by up to 50%
Water Green roof combines with bioswale and rain-garden system to filter runoff
Plumbing Low-flow fixtures throughout the facility
Landscape Facility is integrated with landscape, green roof
Most importantly, nature paths surrounding the plant and signage in the structure teach students and visitors about the various green strategies and devices being used by the facility, educating Hotchkiss’ future graduates on the importance of green consciousness.
