This 8,000-square-foot structure is a prefabricated (post and beam) super-insulated package by Bensonwood Homes. The exterior walls are R-40, and the roofs are R-60. The project has a 45kw photovoltaic system. The windows are a high-end German triple-glazed unit. High-tech daylighting sensors maximize the amount of natural light coming into the center, helping to reduce electricity use by 60%.

Water conservation is a major component of the center’s green features. Low-flow faucets and fixtures conserve water, while rainwater is collected underground in a 1,700-gallon cistern and then used for toilets. The floors and ceilings are made of maple and pine harvested from sustainable forests in Maine certified by the Forest Stewardship Council.

This Net Zero project received LEED Platinum certification and the AIA Vermont Citation for Excellence in Architecture. Maclay Architects received the Zero Net Energy Award at the Northeast Sustainable Energy Conference.
