Sustainable Agricultural Lab (SAL)

The Sustainable Agriculture Lab was designed as a partnership between Evergreen students in the 2009-2010 Environmental Design program and the architects. It is a wood framed building that contains many innovative design features and built-in capabilities, including: rainwater runoff treatment and infiltration, small building footprint, preservation of existing trees, fallen trees used for mushroom production, optimization of daylight through design and electrical light switching, Structural Integrated Panels (SIPs) used for the ceiling, Forest Stewardship Council (FSC) certified sustainable wood products used, permeable gravel used instead of paving for walkways, minimized parking with the addition of a walking / biking trail from the main campus parking lots, building envelope: a) is beyond code requirement for insulation. b) uses spray-on cellulose wall insulation and c) was blower door tested to find air infiltration leaks, and future “Net-Zero” features have been planned and infrastructure is in place for: a) rainwater harvesting, b) compost (or other alternative fuels) heat recovery, C) solar hot water, d) future lecture space, e) greywater reuse and f) photovoltaic on-site power generation.
