From our old friend Sheri Koones in the Huffington Post yesterday. We appeared in prefabulousher popular 2012 book Prefabulous + Almost Off the Grid: Your Path to Building an Energy-Independent Home.

The Passive House (or Passivhaus) (PH) was first established in Germany and is quickly becoming a standard in many parts of the world, including the United States. Whereas other important standards, such as LEED), focus on many environmentally friendly aspects of the home, such as site location, sustainability, materials, water efficiency and so on, Passive House only focuses on energy and ventilation.

LEED Platinum-Certified Bensonwood Project Wins 4th Award

The LEED Platinum-Certified Burr and Burton Academy Mountain Campus in Peru, VT, which Bensonwood designed, engineered and built, is a recipient of the 2014 Governor’s Awards for Environmental Excellence.

Environmental excellence awards have been given since 1993 to recognize efforts and actions of Vermonters to conserve and protect natural resources, prevent pollution, and promote environmental sustainability. To date, more than 200 efforts have been recognized.

“These projects contribute significantly to Vermont’s environmental quality and encourage others to take similar actions to protect our resources,” said Deb Markowitz, Secretary of the Vermont Agency of Natural Resources. “They demonstrate the importance of innovation and partnerships in enhancing and sustaining Vermont’s environmental quality.”

Award winners will be recognized at the Vermont Businesses for Social Responsibility Annual Spring Conference on May 14 at the Davis Center on the University of Vermont campus in Burlington.

This is the fourth award in the past four months for the building. BBA’s Mountain Campus also won Efficiency Vermont’s 2014 Better Buildings by Design “Best of the Best” in Commercial Building Design and Construction, recognizing innovative and integrated design approaches for energy efficiency in Vermont’s commercial and residential buildings.

BBA Heater

The ultra-efficient masonry heater in the school building is integral to warming the building.

In November, the Mountain Campus earned a prestigious Engineering News-Record “Award of Merit” and in January 2014, it won the “AIA New Hampshire Merit Award.” The AIA jury said: “The respect for the environment is as integral to the architecture as it is to the mission of the school. The jury appreciated how the structure, columns, and framing define the composition and are a metaphor for the forest setting.”

Like Unity Homes and other Bensonwood custom timber frame projects, the building was largely prefabricated offsite and erected quickly in the forested setting to minimize impact to the local ecology.

Passive House Wins Award for “Best Energy-Efficient Project”

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.
