Duct & Envelope Tightness Verification
April 8 @ 9:00 am - April 9 @ 5:00 pm
This two-day 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 IECC amendments.
Participants will learn how to explain calculations for ACH50 and percent duct leakage, demonstrate proficiency in testing protocol, apply knowledge on actual blower door and duct systems, and complete a certification exam.
After successful completion of this course, the participant will be able to test the leakage of a building envelope and duct system, and evaluate the results as measured against Georgia code requirements. Specific topics include:
- Protocols for blower door and duct leakage testing
- Calculations for ACH50 and percent duct leakage
- Tips for successfully completing the written and in-field DET Verifier certification exams
- This course also prepares participants to successfully challenge the Building Performance Institute (BPI) Infiltration and Duct Leakage(IDL) certification field exam (available separately). NOTE: The BPI IDL exam and BPI IDL certification are NOT required to become a certified DET Verifier.
