In this inaugural episode of the Retrofit Podcast, host Ryan Shanahan gives you a bit of background on how he got into the world of high-performance building and net-zero energy retrofits. Then, he talks with Josh Salinger, owner of Birdsmouth Design-Build in Portland, OR, about the built environment's impact on climate change, building high-performance homes, and how helping existing homes lower their carbon footprints is a very necessary part of the battle in slowing climate change.
