  • Incredibly Informative

    If you are thinking about building a passive house, this is the podcast for you! I am planning on constructing cabins in East Texas, where the temperature is consistently over 100 degrees Fahrenheit right now! There is no time to waste! I am so thankful for these podcasts and the professionals who are interviewing and being interviewed! We can each help in our own little way to bring the temperature down on our planet.

  • Incredibly helpful!

    Such a helpful and accessible podcast about an important and occasionally technical topic. One minor quibble: it's not atypical, but when a male host interviews a female expert (e.g., the Sian Taylor episode), the host not infrequently interrupts the expert in a way that does not occur in other episodes. Something that commonly happens, for sure (unconscious biases are amazing things), but something to improve upon! Thank you so much for providing such a comprehensive, up-to-date, and invalua... more

Talking Points

Recent interactions between the hosts and their guests.

301: Building the Next Generation of Passive House Professionals with John Loercher
Q: What changes do you hope to see in how we educate professionals entering the building industry, particularly around certification?
A push for universities to adopt PHIUS training as part of curricula, expanding from design professionals to builders and other trades, and reducing barriers to entry so more people can reach certification while improving project outcomes.
301: Building the Next Generation of Passive House Professionals with John Loercher
Q: Can you tell us a little bit more about that training and how PHIUS trades differs from other programs?
PHIUS trades professional training is a newer, hands-on program focused on material choices, sequencing, and real-world assembly construction, designed to move beyond management and into practical implementation.
299: The Missing Standard for Panelized Construction with Johann Betz
Q: How does OSM 3604 relate to existing standards and regulation?
OSM 3604 is described as a code of practice for designers, not a standard; it should run alongside NZS 3604 and may one day become a sub-chapter or companion guideline to help align panelized design with regulatory expectations.
299: The Missing Standard for Panelized Construction with Johann Betz
Q: What is the goal of standardizing the panelized system and why is NZS 3604 used as the baseline?
NZS 3604 provides a single reference point for timber framing that's understood by designers, builders, inspectors, and authorities; the goal is to extend that logic to panelized construction with a defined system that enables DFMA from start to finish, so panels can be manufactured efficiently and inspected consistently.
298: The Potential for Passive House at Scale in Australia with Sven Maxa
Q: What are the practical implications of adopting Passive House with a volume builder like Metricon?
It's about balancing cost and performance; replacing a standard wall with a thicker, more insulated envelope, selecting compatible claddings and membranes, and ensuring detailing supports market-scale production while delivering high performance and resilience.
