A schism in building standards: promoting passive house and high performance building in the USA, with Zack Semke (Passive House Accelerator)

Lloyd Alter introduced us to Passive House Accelerator earlier this year and it turns out that we're doing some quite similar work, promoting high-performance building, sharing innovation, and elevating thought leadership.

Instead of starting a blood feud, we decided to invite Zack Semke onto the podcast to talk about what they're up to and see what we can learn from them. As it turns out, they're doing some really interesting stuff and Zack had already interviewed Jeff ages ago. Seems like we should look into collaborating.

We had a chat about their stateside perspective on high-performance building, how to make sense of the place of passive house globally, and the schism between PHI vs PHIUS standards(European vs US).

It went into a bunch of other things too. All fairly familiar subject matter, substantially less Brexit than usual but more naked culture war nonsense. Whatever we think about the nuance of the standards, it's clear that US adoption of passive house has massive potential to push things forward.
