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.
