…DS+R is designing a new purpose-built home for the Frederick S. Pardee School for Global Studies at Boston University. Upon completion, the 12-story building will, according to the firm, be the tallest mass timber structure in the northeast United States. The Pardee School, established in 2014, educates students in international relations and public policy. …The school’s “vertical collaboration network” will be broadcast on the building’s facade, wherein large spans of glazing reveal the timber construction inside. …The mass timber structure will be all-electric and fossil fuel-free. Its innovative structural frame is estimated to reduce embodied carbon by 87 percent, in comparison to an initial steel-and-concrete iteration.
