#50 | Outdoor Air Isn't Fresh Air: AIRAH IAQ 2026 Wrap Up with Sean Maxwell
Fresh off the AIRAH Indoor Air Quality Conference in Cairns, host Jess Kismet sits down with building science expert Sean Maxwell to unpack essential insights on ventilation, enclosure physics, and moisture control. Together, they discuss wisdom from industry legend Joe Lstiburek, why immediate regulatory action on continuous apartment ventilation beats waiting for perfection, and the necessity of external continuous insulation to protect building envelopes. The conversation challenges traditional HVAC design habits by demonstrating why outdoor air isn't always clean air and advocating for mechanical systems engineered around dew point targets rather than temperature alone.

#6 - Blower Door Testing & The Future of Aussie Homes with Sean Maxwell
In this episode of the Building Sciology Poddie, I speak with Sean Maxwell, the ATTMA Scheme Manager for Australia and New Zealand, about the importance of airtightness testing in building science. We chat about the role of blower door testing, the regulatory landscape surrounding airtightness, and the significance of the NatHERS star rating system. Sean shares insights from recent studies, including the CSIRO report on airtightness in Australian homes, and emphasises the need for better buildin...
