Event Description

This three-day online course is designed to introduce the skills necessary to become a Duct and Envelope Tightness (DET) Verifier, certified to perform the diagnostic testing required for new homes by the 2009 and 2012 IECC amendments (content updated for new Georgia 2020 energy code). 

In this Certified DET Verifier course, you will learn the basic building science concepts and math skills related to air leakage, duct leakage and ventilation in homes. This will allow you to conduct leakage tests in new homes as part of the IECC testing requirements for air-tightness of the envelope and duct work. In existing homes, you can offer retrofit sealing of ducts, walls, floors and ceilings to improve comfort and reduce utility costs for homeowners. Specific topics include:

• Protocols for blower door and duct leakage testing
• Calculations for ACH50 and percent duct leakage

Benefits of getting DET Verifier certification
