313: PhiusCon 26 in Phoenix

In this episode of the Passive House Podcast, Ilka Cassidy and Jay Fox talk with attendees at PhiusCon 26 in Phoenix. The conference opened with Katrin Klingenberg’s framing of Phius 1.0, 2.0 and 3.0 and Zack Semke’s keynote on the “messy middle” of the energy transition. Ilka and Jay took those ideas onto the conference floor and asked everyone the same questions: what does passive building 3.0 mean to you, and what is still in the way of scaling? The answers cover New York’s blower door requirement, underwriting, prefab and design for manufacturing, and each guest's message for Mars.
