This episode of the Passive House Podcast was recorded during the Passive House Network conference in New Haven, Connecticut, hosted at the first certified Passive House hotel in the U.S. Hotel Marcel. Ilka Cassidy chatted with Ken Levenson about the theme “Profit by Experience” and Architect of Hotel Marcel Bruce Becker. Ilka also talked to other attendees like Timothy Lock, Beth Campbell, Karen Ramsey, and Cheryl Saldanha. They discuss Massachusetts code-driven Passive House growth, grid benefits, trade training access, community value, resilience, and the need to address cost, risk, and more in-person collaboration.

Passive House design and construction is a team sport. It requires effective strategies and cooperation, but also precision in the field and the ability to tweak and recalibrate systems once the building is complete. A robust envelope may be the superpower of Passive House construction, allowing for downsized mechanical systems, electrification, and reduced stress on the energy grid, but these benefits are only achieved if everything works as intended.

In this episode, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers include Carmel Pratt of ZAZNRG and Passive House New York on post-occupancy data, Ed May of bldgtyp on modeling literacy, Skyler Swinford of Energy Systems Consulting with Lloyd Alter of Toronto Metropolitan University on refrigerants and water-based distribution, James Peterson of Petersen Engineering on heat pump water heaters, and Nick Nigro of Leggett McCall on what's next at the innovative and enormous Bunker Hill housing redevelopment project.

In this episode of the Passive House Podcast, Mary James and Ilka Cassidy speak with Joel Callow, building physicist and founding director of UK consultancy Beyond Carbon, about scaling certified Passive House delivery in London. Callow explains the firm’s focus on whole life carbon, compact building forms, overheating avoidance, and early-stage design input, and notes the team has grown to 12 people with recruitment challenges as UK training ramps up via the Passive House Trust. He describes Beyond Carbon’s role in helping major developer Barratt adopt Passive House—through lobbying, 12–18 months of R&D, and cost and constructability work—leading to thousands of units in the pipeline and an estimated 15–20,000 London dwellings in progress.
