Passive House Podcast

In episode thirteen of The Reimagine Edit series of the Passive House Podcast, host Zack Semke shares selected clips of insights from Al Mitchell, Kimberly Llewellyn, Greta Tjeltveit, Ya’el Santopinto, Wolfgang Feist, and Lisa White.

This episode is split between two topics. The first addresses one of the most common questions veteran members of the high-performance building community hear from those who are new to the industry: How do you get your start? For some, that route may be through the trades. For others, it may be through design. There are also less orthodox pathways, particularly for folks with backgrounds in modeling, data management, or consulting. No matter what your background is, this episode provides some practical advice on beginning a career in high-performance building.

The second topic is retrofits, particularly the new Phius REVIVE standard. Guests Lisa White and Al Mitchell, both of Phius, describe the basics of REVIVE and how resilience became the driving rationale behind the standard.
