The University of Michigan is constructing the $261 million Biological Science Building in Ann Arbor. Designed by SmithGroup JJR and Ennead Architects, the 300,000-gsf facility will provide open, flexible laboratories for collaborative research as well as classrooms, offices, and a vivarium. The building is sited adjacent to the existing Life Sciences Institute to which it will physically connect. The general contractor for the project is Barton Malow Company and completion is expected in 2018. LEED Silver sustainable design certification will be sought for the facility, which will feature chilled beams, a sophisticated HVAC system, occupancy sensors, and an exterior envelope with a rain screen that will minimize any potential air leakage from the negatively pressurized laboratories.
