Sustainable design elements include clerestory daylighting, exterior sunshades, interior light shelves and an indirect/direct heat exchange HVAC system. The tertiary treatment ponds create a natural landscape amenity and wildlife habitat, with open space walking trails connected to the adjacent park. Along the trails, interpretive signage explains the treatment process.
