To advance a Climate Action Plan to reach net-zero emissions by 2040, Boston University has recently broken ground on the Center for Computing & Data Sciences, a 19-floor complex expected to become the “University’s and Boston’s biggest and most sustainable, energy-efficient building” once built. Toronto-based firm KPMB Architects led the design of the 345,000-square-foot project, which will house BU’s mathematics, statistics and computer science departments under one roof.
