Duct and Envelope Tightness Verification for Code Compliance

Confused by the new energy codes and how they impact your work?

The new codes have resulted in more and more municipalities looking for trained professionals with credentials to be Duct and Envelope Tightness Verifiers.

This online training product will help you sort out the details and acquire your credentials, on line at your own pace!


We have seen 29 states (at last count) pass requirements for Duct testing in order to align with the 2009 or 2012 IECC (International Energy Conservation Code).

One of the requirements of Section 403.2.2 of the code is that all duct systems outside of conditioned space must be pressure tested and verified for proper air sealing. These code updates remove the visual inspection option. On top of that the 2012 IECC requires blower door testing (Building Envelope Testing).

Suited for all professionals: HVAC and Building Performance and Builders - this online training course prepares you to:

  • Meet ENERGY STAR Version 3 duct testing and building envelope requirements
  • Meet the 2012 IECC code requirements for building envelope testing
  • Meet the 2009 IECC code requirements for duct testing
  • Offer duct testing to local builders and HVAC contractors
  • Minimize costly callbacks
  • Improve comfort and safety and increase system efficiency for your clients
