Program Details
Learn
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 airtightness 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. You will learn important protocols for blower door and duct leakage testing as well as calculations to complete ACH50 and percent duct leakage diagnostic evaluations.
This course enables you to help builders meet state building energy codes that now require all new homes in Georgia and Alabama to be tested by a Certified DET Verifier. The DET Verifier Certification has recognition in multiple states under testing requirements for Florida, Illinois, Louisiana, North Carolina, South Carolina, and Tennessee.

Schedule
Students will complete this certification over one week. The course begins with three training half-days, from 9:00am to 1:00pm ET on Monday, Tuesday, and Wednesday. Monday and Wednesday will be live online via Zoom. The second day of training, Tuesday, is offered in a hybrid format, meaning students can choose to attend via Zoom or in person at our training facility in Atlanta, GA.
Southface requires students to pass two exams to become DET Verifier certified. The first exam is an online “written” exam scheduled at 2:00pm ET on Wednesday after the third day of training. Students are then required to schedule a field exam, usually taking place on Thursday or Friday, with Southface proctors. Field exams can be taken in person at the Southface training facility (241 Pine St NE, Atlanta, GA 30308) or via Zoom if the student has access to the required equipment.
