What if better buildings are one of the most practical climate resilience tools we already have?

In this episode of Climate Confident, I’m joined by Darren Macri, Co-CEO of Wythe Windows and rising president of the Passive House Network. We talk about why passive house is not just a building standard, but a practical climate tech pathway for decarbonisation, emissions reduction, energy security, healthier homes, and a more resilient built environment.

You’ll hear why buildings can cut heating loads by up to 90% through airtightness, better insulation, mechanical ventilation, thermal bridge-free design, and high-performance windows. We dig into how this shifts passive house from a niche green design idea into something far more urgent: infrastructure that helps people stay safe during outages, heatwaves, storms, and fires.

You might be interested to learn how leaky buildings can make wildfire damage worse, how poor windows contribute to mould, noise, asthma, and energy poverty, and why retrofitting existing building stock may matter even more than making new builds cleaner. Darren also explains why adoption is often blocked less by technology than by training, policy, codes, business habits, and fragmented construction practices. Imagine that: the physics works, but humans still need meetings.

We also cover affordability, net zero, the energy transition, local manufacturing, and why better buildings can reduce bills while improving comfort and health.

🎙️ Listen now to hear how Darren Macri and Wythe Windows are helping turn passive house into real-world climate action.
