There’s a lot of building science that goes into making passive buildings extremely durable, efficient, comfortable, and healthy. However, one of the things that often gets overlooked when trying to explain the benefits of Passive House is the experience of actually being in one. There is a certain ineffability associated with the experience that defies easy translation into facts and figures, and this can be especially tricky to communicate to clients who are not already enthusiastic about Passive House. However, as revealed throughout episode fourteen of The Reimagine Edit series of the Passive House Podcast, finding ways to frame Passive House as being quieter, healthier, more comfortable, more resilient, and just…better is key to getting them on board.

In this episode, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers include Craig Stevenson, Lindsay Schack, Matt Brill, Graham Irwin, and Michael Ingui.

In episode fourteen of The Reimagine Edit series of the Passive House Podcast, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers in this episode include Beth Campbell, Ryan Abendroth, Mike Fowler, Kevin Brennan, Kara Haggerty Wilson, Nakita Reed, and Michael Ingui. 

In addition to specific deep dives into ventilation systems in hot and humid climates, designing for passive survivability during extreme weather events, and the challenges of marrying historic preservation and high-performance building methods, one theme courses throughout this episode’s collection of snippets: The need for collaboration. Construction is a team sport, and a project’s success depends on the ability of stakeholders with different sets of priorities to put aside their differences and cooperate. As our speakers note, learning to speak the language of different stakeholder helps to bridge the perceived divide between these priorities.
