The 22-story steel framed building has a granite and limestone façade and 784,000 square feet of office floor space. Work on the brownfield site included demolition and abatement of lead, asbestos, PCBs, and mercury; shell and tenant fit-up; new MEP systems; modernization of elevators; and the complete restoration of historic courtrooms, library, corridors, stairways, and fixtures. The rehabilitation preserved the defining Art Deco features including the decorative plaster ceiling, terrazzo floors with marble inlay, decorative bronze fretwork and grilles, and the exterior granite and limestone façade. This is the largest renovation of a federal building in the country to achieve LEED Gold certification. Sustainable design elements were incorporated including a self-sustaining green roof that is the first of its kind in New England—solar panels power the irrigation pumps and cisterns collect rain water to irrigate the plantings. Additional green elements include recycled or sourced regionally building materials, daylight dimming systems and occupancy sensors, and new Boston Landmarks Commission approved energy efficient windows.
