ATTMA Level 1 In-Person Review Session

Review for the exam to become a Registered ATTMA Level 1 Air Tightness Tester.


This workshop covers the essentials of the air tightness testing systems and their software. Understanding how to use a blower door is only the first step. We will concentrate on troubleshooting and understanding what the system is doing and knowing how to use the software to its maximum potential.

The course is designed to take professionals new to the practice of air tightness testing and make them competent in basic tests for houses and simple structures. It will also provide in-depth material on the finer techniques of testing for those with prior experience.

This course will provide an understanding of how ATTMA standards, regulatory standards, and project specifications for air tightness are applied in New Zealand and Australia. We will better understand how test results should be represented and compared, and how they relate to physical processes in real buildings.

The course will prepare you for the open-book knowledge and theory exam, as well as an assessment of competency in using a common blower door system from either The Energy Conservatory or Retrotec.


Attendees should have either attended previous Blower Door training, or have some experience using Blower Door equipment.
