At the 2012 Greenbuild conference in San Francisco, the U.S. Green Building Council named the Puyallup Tribal Longhouse as the LEED for Homes Project of the Year. Located on the Puyallup Tribe reservation outside of Tacoma, Washington, the multifamily project uses structural insulated panels (SIPs) from Premier SIPs to save energy and achieve a LEED Platinum certification.
Traditionally, Coast Salish tribes lived in longhouses with a shared central space and dwelling units off to the side. Architect Environmental Works used this living tradition as an inspiration and created a structure with ten town-homes that are separated from each other by a courtyard with an open, slanted shed roof. Entryways are located in the courtyard, providing occupants with common space in congruence with cultural traditions.
The Tribal Housing Authority benefits from reduced heating and cooling needs thanks to the SIP walls and roof, triple-pane windows, and a ground source heat pump that provides both radiant heating and domestic hot water.
This is not the first year a SIP project has been selected as the LEED for Homes Project of the Year. In 2011, SIPA member GO Logic received the award for their 1,500 sq. ft. zero energy home located in Belfast, Maine.
In addition to claiming top honors at Greenbuild, the Puyallup Tribal Longhouse also received a Social Economic Environmental Design Network (SEED) award for Excellence in Public Interest Design. Now in its third year, SEED recognizes designs exemplifying the collaborations needed to create truly sustainable projects and change in the world. Six projects were selected out of sixty-five submitted from 21 countries worldwide.
