Show Notes
In this episode of the pro clima Podcast, Barry shares with Simon his journey from studying engineering to transitioning into airtightness testing with ATTMA (Air Tightness Testing & Measurement Association) where he has worked for 10 years.
Simon and Barry discuss the process of Blower Door testing and emphasise the importance of airtightness testing for energy efficiency, citing that homes with improved airtightness can achieve up to 35% energy savings for heating alone.
Barry talks about the future of airtightness testing, and how he predicts there to be a shift in the way we test for airtightness, instead he predicted we would be using ‘actual energy usage’ metrics rather than predictive models for evaluating building performance, leading to higher energy efficiency standards.
Throughout the podcast, he shares valuable insights into the importance of airtightness in buildings and the effects on energy efficiency in your home. He encourages others to consider the growing global importance of energy efficiency and sustainable building practices.
“You can make even a 20% reduction in the amount of energy you use. That adds up over 10 years.” Special Guest: Barry Cope.

Simon and Johann discuss the gap between design and manufacture—and how bridging this gap unlocks greater productivity in construction. Johann explores why simply investing in bigger factories or new technology isn't the answer, and why modern high-performance buildings need to be designed with manufacture and assembly in mind from the outset.
Drawing on his own experience building and living in a SIPS Passive House, Toby highlights how construction decisions can improve comfort, energy efficiency and indoor health. He also discusses why builders should look beyond minimum building code requirements when delivering better-performing homes. Toby emphasises the value of collaboration between builders, architects and clients in achieving successful high-performance construction outcomes. Special Guest: Toby Tilsley.
In this episode, Jeff explains why even small changes to inspection processes can have significant impacts and discusses the factors driving higher inspection failure rates during periods of rapid construction growth.
Together with Elizabeth, Everett designed and built a straw bale home that combines natural materials with high-performance building principles, including triple-glazed windows and mechanical heat recovery ventilation. Everett discusses the lessons learned throughout the build, from managing costs and navigating design decisions to balancing sustainability, comfort, and performance. He explains why low-toxicity materials and low embodied energy were key priorities, and how these choices have contributed to a remarkably comfortable home that remains warm, quiet, and healthy year-round. Despite winter conditions, the house has yet to require any active heating, demonstrating the potential of thoughtful design and natural building techniques. Special Guest: Everett Norris.
Jason Quinn, founder of Sustainable Engineering Limited, shares insights from his upcoming book on deep energy retrofits in New Zealand and explains why improving existing buildings is critical for creating healthier, more energy-efficient homes.
