From comparing home health and human health, to breaking down the structural differences between NatHERS and Passive House, Alex shares why building a home is a deeply psychological journey. If you’ve ever felt trapped by rigid building codes or felt that modern design lacks a soul, this conversation will completely shift your perspective on what a healthy home can be.

In this episode of the Building Sciology Poddie, host Jess Kismet welcomes Chris Laumer-Giddens, co-founder of LG Squared in Atlanta, Georgia. Chris has become a leading voice in high-performance building. He refuses to compromise on aesthetics while executing airtight, flawlessly engineered structures and whether tackling new luxury builds or complex historic renovations, his boots-on-the-ground technical consulting bridges the gap between beautiful architecture and real-world construction.

What happens when a top-tier corporate finance expert gets fed up with the investment world and decides to retrain in sustainable building design? You get a refreshing, zero-nonsense look at how badly the Australian housing market is currently failing us - and how we can fix it. This week, Jess sits down with Michael Drage, the award-winning designer behind Reimagined Habitat. Michael treats building science less like an ideological crusade and more like a smart investment strategy: it’s all about research, precision, and de-risking the build. If you’re tired of the "marketing spin" around 7-star energy upgrades and want to understand how a house actually functions for your health and wallet, this episode is a must-listen.

How do you design a home that lasts centuries? Renowned architect Steve Baczek (The Build Show, Unbuild It Podcast) joins me on the show to break down the fundamentals of building science. From the "Perfect Wall" to the four critical control layers, Steve explains why "buildings needing to breathe" is a dangerous myth and how collaboration between architects and builders is the key to success.

Is your home actually making you sick, or is there more to the story? In this episode, I’m joined by Zara D’Cotta, founder of The Healthy Home, to explore the intersection of traditional construction and human biology. Zara shares the personal health journey that led her to building biology and presents her case for why "sustainable" design doesn’t always equal a healthy living environment. We look at everything from the hidden trade-offs of recycled insulation to EMFs and lots more. The world of EMFs can feel overwhelming and is often met with plenty of scepticism. In this conversation, Zara and I discuss the gap between current building codes and research, so whether you’re a firm believer or still weighing the evidence, this episode is a deep dive into the science, the controversy, and the evolving global standards of EMFs and building biology.
