Be the Developer, the Architect, and the Builder - Vertical Integration with Tim McDonald

from Build It Forward · host Nick Falkoff and PRMEABL_

Become the developer. Become the architect. Become the builder. Tim McDonald didn't do this because it seemed like a good idea. He did it because he couldn't figure out any other way to build what he was trying to build. In this conversation on Build It Forward, recorded at Tim's home on the North Shore of Boston, Nick Falkoff sits down with Tim, co-founder of Onion Flats Architecture, for a conversation that spans nearly 30 years of design-build development in Philadelphia. Tim talks about how he came to passive house in 2008, why he sees it as the only serious answer to what climate change demands of buildings, and how the New Gravity concept helped bring passive house into affordable housing funding applications across 40 states. The conversation also gets into where the work is headed: deep energy retrofits on existing multifamily buildings, panelized wall systems that wrap buildings from the outside while people are still living in them, and the case for why retrofitting existing buildings is more cost effective than tearing them down.
