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.
