In this episode of the pro clima Podcast, Steve shares his journey from living in a renovated 1860s villa in Ponsonby, Auckland, to building an off-grid Passive House in Coromandel. He recounts how the villa’s renovation revealed issues with heat retention, leading to high energy costs and discomfort. This experience, along with a desire to live more sustainably, inspired his family's move to Coromandel, where they began with minimal infrastructure, even living in a tent while constructing their new home.
Steve discusses with Simon the process of building the new passive home, emphasizing the importance of energy efficiency through careful design and the challenges of using unconventional building materials. He explains the significance of proper ventilation, airtightness, and thermal performance for a comfortable home environment and provides insights on energy modelling, cost considerations, and meeting Passive House standards. Steve also addresses the broader context of New Zealand’s housing, stressing the need for improved thermal performance and energy efficiency.
Throughout the podcast, he shares valuable lessons from his hands-on experiences and encourages others to consider sustainable building practices, whether in new constructions, smaller dwellings, or retrofitting projects. Special Guest: Steven Hughes.
