In this episode of the Pro Clima Podcast, Simon Cator talks with Auckland-based (but Toronto born and raised) building enclosure engineer Peter Raimondo about adapting building science principles from Canada to New Zealand. Raimondo discusses challenges in local construction practices, the importance of airtightness and ventilation, and how controlled airflow prevents condensation and energy loss. He also shares insights from blower door testing, international best practice, and his role as MC for the upcoming Building Science Summit, focused on industry collaboration and knowledge sharing.

Special Guest: Peter Raimondo.

Simon Wandsborough joins the pro clima Podcast to discuss his journey from outdoor instructor to eco-conscious builder and the thinking behind his business, Third Little Pig. He shares how growing up in New Zealand and completing an adult apprenticeship shaped his focus on building better, more comfortable, and energy-efficient homes.
The conversation explores high-performance building principles such as passive solar design, insulation, airtightness, and quality windows, alongside the need for better education and early collaboration between clients, architects, and builders. Simon also reflects on the limitations of New Zealand’s building code, common misconceptions around cost and airtightness, and what’s next for Third Little Pig.

In this episode, industrial designer Andre Heller shares how his diverse background, from boat building to underground station construction, has shaped his fresh approach to prefabricated housing. Through his company, Flexi House, Andre is redefining offsite manufacturing by prioritising speed, efficiency, and consistent quality. Their lightweight timber frame system, complete with continuous insulation and air barriers, delivers a minimum 46% boost in thermal performance over standard New Zealand homes with the potential to reach Passive House levels, making high-performance building more attainable. Andre also dives into his vision for making offsite construction as simple and accessible as ordering from an IKEA catalogue—dramatically reducing waste while transforming the way we build.

In this episode, Sharon Robinson, architectural designer, certified Passive House and Homestar designer - shares how her company Smart Living Spaces, is redefining housing accessibility through its innovative Small, Smart Spaces concept. By combining the benefits of group housing, bespoke design, and offsite construction, Sharon is helping make high-performance homes achievable for more New Zealanders. She also explores how Homestar-rated homes can impact energy bills by up to 50% improvement in health and comfort with the same or lower power bills people are used to paying and unlock better mortgage rates, while emphasizing the power of collaboration between designers, builders, and mortgage brokers to deliver affordable, efficient, and healthy homes.

Dr. Antony Pelosi, a researcher and educator at Victoria University, discusses his journey from building science to architecture, including his time at the University of California, Berkeley. He shares his PhD on spatial comprehension in BIM models and the early use of AI for pathfinding. Pelosi is currently designing and building a $300,000 passive house, emphasising cost-effective materials and energy efficiency. He explores AI's role in architecture, highlighting its use in text generation, image rendering, and 3D modelling. Pelosi also discusses the potential of AI in construction, sustainability analysis, and the need for reimagining design and delivery processes to improve efficiency and reduce liabilities.

In this episode, Casper Valintin shares his journey from a childhood split between Brunei and Scotland to careers in horticulture and IT — and ultimately, to a deep passion for high-performance building. After constructing his first ICF block home in Hamilton, New Zealand, Casper became a strong advocate for Passive House principles. He talks through the features of his own home, including 400mm of roof insulation, continuous slab insulation, and a Zehnder ground-source ventilation system. With sensors tracking performance, he’s fine-tuned the house to maintain a consistent 20°C indoors — proving how smart design, insulation, and ventilation can deliver lasting comfort and efficiency.

In this episode, building scientist Dr. Allison Bailes shares his journey from physics academia to the world of building science. He discusses the importance of airtightness in homes, explaining how it directly impacts indoor air quality, comfort, energy efficiency, and moisture control. Bailes challenges the myth that houses need to “breathe,” advocating instead for air-tight construction combined with well-designed ventilation systems.
