  • 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.

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.
298: The Potential for Passive House at Scale in Australia with Sven Maxa
Q: How did you first get into Passive House, and what held you back initially?
My first encounter was with a prospective client who asked us to look at Passive House; I wasn't convinced at first, largely due to unfamiliarity with the PHPP process and air tightness concepts, and because we were deeply involved in NatHERS at the time.
298: The Potential for Passive House at Scale in Australia with Sven Maxa
Q: Tell us a little bit about where in the world you are.
I'm in Melbourne, Australia, in a bungalow I've lived in for 20 years; it's a practical base from which to discuss the local Passive House scene and adjacent conference activity.
296: Inside Thrive 2026 with Andy Marlow
Q: How are key Australian builders approaching Passive House, and what are the commercial drivers?
Builders like Fraser's and Metricon are experimenting with offering Passive House as a product within their existing systems, prioritizing ventilation and airtightness as cost-effective performance drivers while leveraging their supply chains. This signals a shift from bespoke, standalone projects toward scalable, repeatable approaches that can fit their current business models.
296: Inside Thrive 2026 with Andy Marlow
Q: What were the main takeaways from Thrive 2026 regarding scaling Passive House in Australia?
The event demonstrated a broadening of the audience to include volume builders and retirement living developers, with a focus on practical delivery changes such as prefabrication and better ventilation strategies to gain performance without prohibitive costs. It also highlighted systemic delivery issues and the need to rethink contracts, supply chains, and on-site processes to enable scale.
