  • 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.

308: Putting Pride Back in Construction with Tomás O'Leary
Q: How do you scale Passive House across multiple large sites without compromising quality?
The approach combines a rigorous early feasibility and phasing process (PHPP-based checks), benchmarking at the unit level, on-site training of contractors, and a shift away from over-reliance on Passive House consultants. By upskilling the workforce, standardizing practices, and using practical tools like primer visualization and smoke tests, projects stay on program while increasing quality and speed.
307: Josh Dorfman on Building Carbon-Negative Materials
Q: What sparked Plantd's shift from traditional plywood to carbon-negative panels?
Dorfman explains that price shocks and quality issues with FSC plywood during the pandemic pushed them to seek an alternative feedstock and process that could scale while removing carbon, ultimately leading to a hemp and perennial grass-based system.
Bonus Episode: Resilience, Retrofits, and the Road to PhiusCon 2026
Q: What is the central theme for PhiusCon 2026 in Phoenix?
The central theme is resilience in hot climates, focusing on robust envelopes, smart design, energy efficiency, and the ability to operate under extreme conditions, including the use of solar and battery storage.
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.
