Armstrong-Barnwell Home

– 14 photovoltaic panels, with an output of 295 watts/panel. Total output: 4.13 Kwh. Panels oriented due south, mounted flat on roof. Production since installation has averaged approximately 480 Kwh/month.,/p>
– House is rectangular shape, north half is dug into hill, most of glazing on south side, for “passive solar” type design.

Dean Family Farm and Art Studios

– Solar thermal / Wood boiler combi-system
– KOB Pyromat Eco, indoor wood boiler features an oxygen sensor in exhaust flue.
– Large, ground mounted solar thermal array consisting of 12 flat plate collectors & 224 evacuated tubes mounted on a rack built from salvaged steel and insulated with salvaged materials.
– Automatic array shade for overheat protection and maintenance.
– 150’ long insulated underground supply and return piping, with a heat loss less than 1º in winter, was built using salvaged insulation materials.
– Innovative, double primary loop hydronic design allows boiler and solar to work in tandem, or independently, in several different modes for the most efficient operation.
– Custom system controller uses 1-wire technology.
– Custom controller software was written using the Panorama database program and features a graphic display of system with pipes that change color with fluid temperature.
– Variable speed pumps throughout, featuring software controlled flow limits to prevent pipe corrosion during high temperature operation.
– Homemade, variable area heat exchanger valves allow for efficient flat plate heat exchanger operation at flows between 1 and 18 gpm.
– Flat plate collector bypass valve allows for 30 – 45 minutes of extra production from evacuated tube collectors at end of day.
– Heat exchanger frost protection bypass valve and Jaga low H2O radiators.
– 1100 gallon, under floor, heat storage tanks feature horizontal stratification.
– Covered firewood storage with tip through, wall mounted wood box.
– Winch operated laundry drying rack; Solatube skylights; And more…

Downey-Garity residence
