This collaborative Vermont Passive House project in Norwich VT was built under a Shell Package contract. A passive house is a very high energy standard for a northern project. Simply put, it takes a lot of planning to build a home in VT that doesn’t need a heating or cooling system. The goal was to provide an airtight shell (ACH50 of <6) within few days of arriving on site. The team for this acclaimed project consisted of multiple designers and architects.

ENERGY DETAILS

This air-tight, super-insullated house is certified under PHIUS + Passive House, and ENERGY STAR programs. 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 (from ZED 05MAY09). Roof: R-86 (nominal) Wall: R-55 (nominal) Basement:R-38 (nominal) This foundation will have an actual R-value of 40. Slab:R-71 (nominal) ve an actual R-value of 72. The threshold is 4.75 kBtu/square foot. For the Landau residence, this works out to be 129 therms natural gas / 141 gallons propane / 3781 kWh electricity / 1/2 cord of hardwood per year for heating, total.
