The Comfort Revolution: Why Passive Houses Matter

Send us a text

In this episode, Janey chats with Mark from MA Building about the growing movement of passive houses—homes designed for energy efficiency, comfort, and health. They break down what a passive house really is, why these homes feel consistently warm and fresh all year round, and how they reduce energy use dramatically.

Mark shares insights on the holistic approach to building, from insulation to ventilation, and the challenges of changing old-school building mindsets. They explore the real health benefits of living in a dry, mold-free, toxin-reduced environment and how passive houses can future-proof our homes and reduce national energy demands.

Whether you’re building new or renovating, this episode offers practical tips on where to start, how to think about cost versus long-term value, and why a shift to passive houses is not just smart—it’s essential.
