Presented by Ryan Dalgleish

Learning Objectives:

  1. Identify current building code requirements on both a national and jurisdictional level, and requirements of various green building programs.
  2. Articulate what the test provides and how the results can be used to improve the building enclosure.
  3. Define the differences between all the test methods available as code or specification options.
  4. Determine the industry resources that exist in developing contract documents for whole building airtightness testing.


As an IACET Accredited Provider, BNP Media offers IACET CEUs for its learning events that comply with the ANSI/IACET Continuing Education and Training Standard.

Whole building airtightness testing has been a code compliance option in the International Energy Conservation Code and ASHRAE 90.1 for some time.

That compliance option is rarely used and only becomes mandatory as part of a building owners’ requirements, or a specific state or jurisdictional requirement.

As we move towards net-zero, building codes will “tighten” up and is expected to become a test that is mandatory on a more country-wide basis.

It is important to understand the latest in test methods, current and projected code requirements, training and certification requirements and resources to allow you to specify this requirement.
