The American Institute of Architects has released its 18th annual list of the best new examples of sustainable architecture, and this year’s winners include a treehouse in West Virginia and the California headquarters of the Packard Foundation.
According to the AIA, the winning projects “showcase excellence in ecological design principles and reduced energy consumption.”
U.S. Land Port of Entry; Warroad, MN: The building is constructed of sustainably harvested cedar, and sustainable features include a ground source heat pump system, rainwater collection, and extensive use of recycled materials.
Sustainability Treehouse; Glen Jean, WV: Located in the Summit Bechtel Reserve, the building allows visitors to experience the forest from multiple points. Innovative solar, wind, and water-cleansing systems combine to yield a net-zero energy and net-zero water facility.
Bushwick Inlet Park; Brooklyn, NY: Part of the transformation of the Greenpoint–Williamsburg waterfront from a decaying industrial strip to a public park, this project houses meeting rooms, classrooms, and maintenance facilities. The facility becomes a green hill on one side, making it 100% usable to the public.
Bud Clark Commons; Portland, OR: Part of Portland’s plan to end homelessness, the building provides various services to help transition homeless individuals, including a day center, temporary shelter, and 130 studio apartments. Sustainable features include large-scale graywater recycling, solar hot water, and a high-performance envelope, resulting in energy savings estimated at $60,000 annually.
