In this episode of the Passive House Podcast Mary James and Jay Fox chat with Sarah Lewis, Research and Policy Director at the Passivhaus Trust. They explore Scotland’s groundbreaking push toward mandatory Passive House standards for new buildings.  Sarah dives into the motivations behind the proposed legislation, lessons from Germany and Brussels, and the vital role of embodied carbon. She also explores the practical implications—from fuel poverty and ventilation standards to supply chain readiness and the challenge of scaling EnerPHit retrofits. With clarity and passion, Sarah unpacks how policy can drive meaningful change in the built environment.

In this episode of the Passive House Podcast Architect Nat Madson and structural engineer Lauren Piepho of HGA join us to talk about Barry Mills Hall and the John and Lile Gibbons Center for Arctic Studies—Bowdoin College’s first mass timber buildings and the first of their kind in Maine. They share the story behind the design and construction, from early ideas sparked by the college’s pine-filled campus and carbon neutrality goals, to navigating mass timber systems, embodied carbon, and the buildings’ architectural dialogue with campus history.

In this episode of the hosts Mary James and Jay Fox sit down with Vincent Bergeron, an architect with Equipe A Architects in Quebec, to explore The Monarch—a groundbreaking social housing project in Sherbrooke. With 134 units guaranteed affordable for 35 years, this high-rise development is notable not only for its scale but for its ambitious pivot toward Passive House principles. Van shares how a tight timeline, a challenging site, and a collaborative team led to innovative choices in prefabrication, envelope design, and energy efficiency. Hear how a late-stage decision to pursue Passive House certification helped shape a healthier, more resilient living environment for low-income families, all while keeping costs in check.

In this seventh episode of The Reimagine Edit (TRE) series of the Passive House Podcast, host Zack Semke shares selected clips of insights from Jessica Grove Smith (Joint Managing Director of Passive House Institute), Mark Attard, Rainger Pinney, John Loercher, Galen Staengl, Mike Fowler, Cait Eggers, Sean Velez, Nidhi Shaw, and Lloyd Alter.

Quotes:

"Walking off the ferry in Seattle and ashes falling out of the sky—that changes your perspective. The same thing with the heat dome and with COVID. These events over the last seven to eight years have reshaped how I think and approach design and architecture, and now my focus is on resilience." — Mike Fowler

"If you touch any one single component, make sure you go all the way. That’s the only way you’re going to future-proof your building and have a long-lasting carbon emission impact." — Jessica Grove-Smith

"It’s very clear that what typologies get built follow where there’s grant money. Developers are happy to build anything as long as it comes with a little extra funding—that’s a powerful lever we can use to shape the built environment." — Rainger Pinney

"In Passive House buildings, humidity changes very slowly. That just observation applies in any climate—you’re less affected because the air isn’t running through your building like it does in most buildings." — Galen Staengl

"We should be retrofitting schools rather than demolishing them. Roofs, windows, and wall cladding can be replaced; we don’t need to demolish the whole school to make it better." — Nidhi Shah
