It is assumed today that buildings should contribute positively towards energy and environmental sustainability. However, few buildings aim to remediate the environment and even fewer aim to do so with passive non-mechanical means. Emerging research in photocatalytic architectural concrete has drawn a renewed attention to the role that building facades can play in contributing toward the profession’s sustainable goals while improving value. We will report on the work carried out by a team comprised of faculty from Architecture and Environmental engineering that incorporates environmentally derived design and innovative photocatalytic concrete into the design of a panelized concrete façade.
