A USBGC 30-year look back. I was speaking at a conference organized to address the rise of sustainability as a focus for design professionals; it was the early 1990s. Held at the Southern California Energy Resource Center, a beacon of light in leading sustainability. That day, I met Rick Fedrizzi with Carrier, a major HVAC equipment manufacturer. This video documents 30 years of the history of this movement and captures the importance of the architecture and design industry acceptance at that time.
