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.

What is Zero Ambitions Podcast?

Zero Ambitions is a consultancy and weekly podcast about sustainability and the built environment.

We find interesting and experienced guests who know what they're talking about, usually to discuss how we navigate the complexity of decarbonisation and sustainability in the built environment and its many related sectors.

The success of the podcast has seen it grow into a consultancy, Zero Ambitions Partners. The consultancy works with blue chip clients, public sector institutions, and niche-market innovators that operate in the built environment, advising about the development and delivery of sustainability strategy and how it should be communicated.

Hosted by Jeff Colley (Passive House Plus), Dan Hyde (Everything is User Experience) and Alex Blondin (Everything is User Experience).
