Zero carbon buildings are not a thing of the future. They are being built now at all scales, locations, and building types throughout Massachusetts. This session will present three net zero carbon projects representing small and large, urban and suburban, and private and public; a midrise multifamily, a public school, and a high-rise office building. An overview of the design strategies and processes, including cost-benefit and life cycle cost assessments, will be given followed by a panel discussion with the owners and developers of each project. The discussion will focus on the factors that made the net zero decision possible for each project.
