Steven and Barbara Landau’s Norwich, Vermont, Passive House won The Builders and Remodelers Association of Greater Boston (BRAGB) Prism Gold Award for “Best Energy-Efficient Project.” Bensonwood, who designed the prefabricated insulated panels and constructed the timberframe shell, was honored as part of a highly-skilled green building team that included energy modeling and mechanical consultantsZeroEnergy Design, consulting architect Paul R. Bilgen, general contractor Estes and Gallup, and custom window and door maker, Architectural Openings. The innovative, sustainable home previously won the 2012 Efficiency Vermont “Best of the Best in Residential New Construction” Honor Award.
The 17-inch recycled foam sheet insulation provides R-75 value and a vapor barrier below the slab. All hot water is provided by two rooftop, flat-plate solar collectors with an electric on-demand water heater for backup. One kilowatt heating mats located under floor tiles in the bathrooms supply radiant heating, and air exchange is managed by a Heat Recovery Ventilator whose operation automatically adjusts, depending on temperature, humidity, and occupancy. In the kitchen/living room a sealed combustion chamber wood stove serves both as cooktop and bake oven, as well as a source of supplemental heat. The eco-friendly 2,457 square foot home also earned 41 Home Energy Rating index points, meaning it is 59% more efficient than a standard new home.
BRAGB, a trade association affiliated with the National Association of Home Builders and Home Builders Association of Massachusetts, has represented the building industry since 1944 and is one of the leading trade associations in New England.
