World’s largest passive house rising in Boston

The 690-foot-tall Winthrop Center now under construction in Boston will be the largest Passive House Institute-certified office building in the world when it’s completed in 2022. The building was designed by Handel Architects [Gary Handel (B.Arch. '78); Blake Middleton (B.Arch. '78, M.Arch. '81)] based in New York. The building is projected to use 65 percent less energy than similarly-sized projects in Boston and deliver 30-to-50-percent more fresh air than comparable buildings.
