In this episode of Building Tomorrow, we speak with David Gottfried about his upcoming book Regen 360: An Operating System for a Regenerative Earth. David is a founder of the Green Building Movement and has dedicated three and a half decades toward changing how buildings are designed, built, and operated. The book is described as part memoir, part systems argument, part personal reckoning. In our conversation, we reflect on the origins of the movement, where he sees the industry as it stands, and the shift in outlook to make in order to achieve the kind of climate impact we need.
