In this episode, we sit down with Harley Truong, the godfather of Passive Houses in Australia, to explore his incredible journey from public servant to sustainability pioneer. Twelve years ago, Harley was working at the Department of Defence in Canberra when he decided he'd had enough of Australia's zero-star energy efficiency housing and drafty homes. We dive into how he took on the ambitious challenge of building his own passive house without ever having stepped foot in one, using research from Germany's Passive House Institute to create what would become a trendsetting masterpiece.

We talk about the reality of building without a blueprint and how Harley had to literally rewrite the rules to achieve his vision. His meticulous approach resulted in an astounding 0.1 air changes per hour—and we explore what that actually means and why it matters. The conversation gets really interesting when we discuss how one exceptional house wasn't enough for Harley, leading him to recognise a massive gap in the Australian market and found Logikhaus to import high-performance European windows, essentially becoming both consultant and supplier to help other builders achieve their eco-dreams.

Throughout our chat, we explore Harley's bigger vision for the industry and how he's catalysing crucial conversations about providing better, more sustainable housing for all Australians. We discuss his goal of making high-performance windows the norm rather than the exception, and why he believes we're just at the beginning of an inclusive industry revolution. If you're interested in sustainable building, pioneering business moves, or just love hearing about someone who dared to dream bigger, this conversation will inspire you.

"What happens if I make my house airtight but have no mechanical ventilation?" This question comes up more often than you'd think, and the answer might surprise you. We sat down with Cameron Munro from Passive Analytics and Brad McEwan from Sanford BuildCo to tackle this and other building questions from our social media following that every builder should understand.

Building a high-performance home isn't just about achieving airtightness - it's about understanding how all building elements work together. The key takeaway? You cannot have an airtight building without proper mechanical ventilation. The energy and comfort benefits only work when you maintain healthy indoor air quality.

For builders serious about high-performance construction, remember that details matter, and investing in proper ventilation systems isn't optional - it's essential for creating truly healthy homes.

Winter hits different when you're working outdoors. The sun disappears by 4 pm, the cold seeps into your bones, and suddenly that motivation you had in summer feels like a distant memory. If you've noticed your mood dropping with the temperature, you're not imagining things. We sat down with our good friend and psychologist, Julie to understand why winter affects us so deeply and what we can actually do about it.

Winter challenges are normal, but they don't have to derail your mental health. These strategies work best when implemented consistently, not just when you're already struggling. If you notice symptoms persisting or worsening, professional help can make a significant difference.

Remember, acknowledging winter's impact on your mental state isn't weakness, it's awareness that leads to better self-care.
