The 384,000-square-foot Hennepin Healthcare Clinic and Specialty Center in Minneapolis, Minnesota received LEED Gold certification.
The brownfield redevelopment site incorporated the residential neighbors to the south in both design and amenities, including open space and a pocket park that exceeded city requirements, as well as underground parking and stormwater retention system to improve land use, reduce run-off and avoid surface parking. Plant selections and more efficient irrigation methods reduce water use by more than 50% compared to traditional landscaped sites.
The use of low-VOC materials and a building flush-out before occupancy helped create a healthy indoor environment. Walk-off mats at entrances control contaminants entering the facility, and Hennepin Healthcare also incorporated policies to minimize waste and optimize pest management. In addition, energy-efficiency strategies for the ambulatory center reduced the estimated energy use by more than 21% compared to a LEED baseline building. The project team included BWBR and Mortenson Construction.
