Better Buildings for Humans, host Joe Menchefski welcomes back Dorit Aviv, joined by Eric Teitelbaum, for a powerful conversation on one of the most urgent—and often overlooked—climate challenges: extreme urban heat. Drawing from their work at the University of Pennsylvania and AIL Research, they unpack how the urban heat island effect disproportionately impacts vulnerable communities and why conventional cooling solutions fall short. They explore an innovative breakthrough—membrane-assisted radiant cooling—and how it reimagines comfort by cooling people directly, not the air around them.
