    TRE 15: Are You Experienced?

    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. The Reimagine Edit is a special series of the Passive House Podcast that shares curated insights from our Experts-In-Residence at the Reimagine Buildings Collective, our membership community of building professionals stepping up to tackle climate change.
