Bensonwood Educates at Greenbuild 2014 New Orleans

2015 GREENBUILD BANNER

Bensonwood architect Randall Walter, AIA, LEED AP led an education lab at this year’s Greenbuild Conference in New Orleans titled, “School Building as Teacher: Design for the Future.” Learning objectives for the session were to understand:

  • Outcomes of promoting social change through synergistic curriculum and building/campus design.
  • Impacts of building systems and resource transparency on student learning.
  • The synergies between green building and impacts on student learning.
  • Unintended consequences and learning opportunities from this project.

Built and opened to students in 2012, Burr and Burton Academy’s Mountain Campus is an innovative model for place-based environmental education. From campus design and construction to curriculum design and execution, all elements of the process have worked to maximize the success of the program mission: to be a catalyst for student growth as individuals, members of communities, and citizens of a sustainable world.

Walter discussed design concepts that helped the campus achieve “net zero” targets, as well as biophilic design, student experiences monitoring the building’s energy performance, living in and caring for the space, and the ripple effects of student experiences. The design, construction and active use process, including initial design goals, site evaluation, review of LEED criteria, design process charette, site schedule and assembly of the building, occupation, and daily and seasonal changes during the first two years of operation were discussed.

This award-winning project exemplifies how a school design can benefit both students and education professionals. Emphasis on the connections between effective learning environments, innovative green design, and the natural environment are at the heart of the educational program and creative process for this building.

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.

At Bensonwood we’re proud of our nearly 40 year history as the premier designer/builder of energy-efficient timber frame, hybrid, and other high-performance homes.

But we have also built a strong reputation for designing and building LEED certified, energy efficient and architecturally striking commercial buildings and specialty structures.

Recently, Bensonwood Lead Architect Randall Walter and other members of our architecture and engineering team designed the Burr and Burton Mountain Campus Academic Building.

Dedicated on August 23, 2012 in time for the opening of the school’s fall semester, the building is designed to be a living classroom with a goal of achieving LEED Platinum designation and Net-Zero energy status.

Randall worked closely with the Burr and Burton team to ensure that the building not only fit into the natural surroundings of the site but truly became part of the learning experience for students, blending scientific architecture with artistic abstraction. Design features include ceilings inspired by the structure of the underside of a leaf, a skylight that casts light on the native Vermont slate clad masonry heater, between two reclaimed oak trees primary walls splayed at 14.5 degrees, celebrating the variation between true north and magnetic north in southern Vermont.

In keeping with typical Bensonwood design and construction practices, locally sourced materials where used wherever possible.

Speaking at the dedication ceremony Randall noted that a quote by Winston Churchill inspired the design – “We shape our buildings; thereafter they shape us.”
