#6 - Blower Door Testing & The Future of Aussie Homes with Sean Maxwell

  • Resumen

  • 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 building practices to improve energy efficiency and indoor air quality. The conversation highlights the ongoing efforts to raise awareness and drive positive change in the construction industry.
