All major renovations and new construction at Seattle Colleges must be built to LEED standards. LEED buildings are resource efficient to reduce environmental impacts of construction and life cycle costs of the building.
While all new construction and major renovations at Seattle Colleges is built to LEED standards, older areas of the campuses have been retrofitted to conserve energy. For example, occupancy sensors have been installed in many buildings to reduce energy usage from lighting unoccupied spaces.
Several campuses have converted diesel mowers and equipment used to maintain the grounds to B99 (i.e. 99% biodiesel). Biodiesel uses recycled materials and burns cleaner than diesel, reducing emissions on our urban campuses. Additionally, many carts and equipment have been converted or replaced to electric, greatly reducing greenhouse gas emissions and particulates.
