Hotchkiss School Biomass Heating Plant

At the time of completion, the biomass central heating plant at Hotchkiss School was one of only three LEED certified power plants in the country.  The 16,500 SF building includes the boiler plant area, plumbing and electrical shops, educational/classroom spaces, offices, toilet/shower/locker room, and support spaces.  The campus heating plant and support equipment includes: two biomass steam boilers with a combined capacity of 15,000 to 20,000 lbs/hr steam, and a back-up oil fired steam boiler with a capacity of 10,000 lbs/hr steam.  There is a hot water heat exchanger, and pumps for service to Mars Athletic Center.  There is a 17,500 cu. ft bin for wood chip storage and parallel material handling systems.  Emissions clean-up equipment consists of cyclone separators and an electrostatic precipitator.  Normal and emergency standby power systems, including new electric service, power distribution and emergency generator are a part of the design.  Renewable energy demonstration systems, consisting of a combination of small-scale solar thermal, photovoltaic and wind energy systems are also a part of the project design.  Biomass heating is reducing Hotchkiss’ carbon footprint by more than six million pounds of carbon dioxide each year.
