Agenda
Airtightness Masterclass
Thursday 22 October, 2026
12.30pm Welcome and introduction
Moderator: Jim Ng, Technical Services and Innovation Lead, Green Building Council of Australia
12.32pm Presentation: Examining the minimum expectations for airtightness requirements in Green Star Buildings
Airtightness is now a minimum expectation under Green Star Buildings, setting a new standard for improved building practices and performance outcomes. Hear more about how the rating framework aims to improve whole-building performance.
Speaker: Jim Ng, Technical Services and Innovation Lead, Green Building Council of Australia
12.50pm Presentation: Blueprint for success with airtightness: documentation and design reviews that do something useful
This session will take you through the steps to navigate the submission documentation process and draw on project examples with measurable results. Hear more about commissioning testing and how to review any oversights in the process.
Speaker: Sean Maxwell, Scheme Manager, ATTMA Australia and New Zealand
1.30pm Discussion groups: Common challenges and solutions in achieving airtightness
