ATTMA Level 2 Blower Door Testing
Online theory (self-paced) + 2-day practical workshop + theory & practical exams
19-20 March 2026 Cromwell
Who this is for
ATTMA Level 2 is designed for people who already have Level 1 and need capability for commercial and more complex airtightness testing — including the kind of work required on Green Star projects in New Zealand.
- Main contractors and site QA leads on Green Star / high-performance builds
- Façade / air barrier leads and envelope contractors
- Commissioning and building services coordination teams
- Green Star assessors and sustainability consultants
- Airtightness testers ready to move from houses into larger buildings
What you’ll learn
- How to plan and set up tests for larger, more complex buildings
- How to deal with tricky test boundaries, multiple zones and real on-site constraints
- Advanced troubleshooting for inconsistent readings and “this building is doing weird things” scenarios
- How multi-fan / multi-zone testing works (and how to run it cleanly)
- Approach to Green Star / compliance-style airtightness testing and reporting
- Exam prep + sitting the theory and practical exam for ATTMA Level 2 certification

People working on commercial and complex buildings—main contractors, façade/envelope leads, commissioning/services coordinators, sustainability consultants, and Green Star assessors who need airtightness testing capability that stands up on compliance projects.
Is this course relevant to Green Star buildings in NZ?
Yes. Level 2 aligns with the type of commercial airtightness testing and documentation typically needed for Green Star projects and other high-performance builds.
Do i need my own blower door kit?
No. You’ll get hands-on time with equipment during the practical workshop, including advanced setup concepts used on larger buildings.
What do i need to complete before the Cromwell days?
The online theory modules. They’re self-paced and need to be done before the practical workshop so you’re ready for the hands-on work and exams.
Will we cover multi-fan / multi-zone testing?
Yes. Level 2 includes the principles and workflow for multi-fan / multi-zone testing and how to run it cleanly.
Will we cover test boundaries and tricky site conditions?
Yes. Planning and setting the correct test boundary on real commercial sites is a key part of Level 2, including what to do when the building isn’t “test-ready”.
Is there an exam?
Yes. The course includes both a theory exam and a practical exam for ATTMA Level 2 certification.

I’m a Green Star assessor—do i need to run tests myself?
Not always. But understanding how tests are planned, run, and validated makes documentation review faster and helps you spot issues before they become programme or compliance problems.
