Illinois state energy code requires blower door and duct leakage testing on every new home. The IAER's DET Verifier certification is recognized by the state of Illinois (along with BPI, HERS, and WAP Certification) to demonstrate blower door and duct tightness test competence. See the list of certified professionals. DET Verifiers are trained and quality-assured on an annual basis to:
This 1-day course is designed by the IL Assoc. of Energy Raters (IAER) 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 2012 IL Energy Code. If you've been thinking about getting BPI or HERS Certified but can't yet make the investment, this DET Verifier certification can be your bridge into offering home performance testing services.
After successful completion of this course, you will be able to test the leakage of a building envelope and duct system, and evaluate the results as measured against Illinois code requirements. Specific topics include:

Reviews from past DET Verifier Training Participants:
"You did an incredible job. Learned more in 8 hrs than I have in other classes that I have taken elsewhere."
"At first I was a little nervous about the word 'geometry', but in the end it was all math I knew. The amount of time we were able to work hands-on with the controls left me being able to set up the blower door and duct blaster with ease. "
Illinois Association of Energy Raters & Home Performance Professionals (IAER) Introduces New Certification Training in Accordance with Updated Illinois State Energy Code Mandating Air Leakage Testing
Duct & Envelope Tightness (DET) Verifier certification offers excellent opportunity for homebuyers and contractors to prove homes are well built
CHICAGO, December 5, 2012 –On January 1 2013, when Illinois adopts a new statewide building energy code, every home built will need to be tested for tightness of the building envelope and the ductwork. In order to help supply competent professionals everywhere across the state, a new certification training will be offered by the non-profit Illinois Association of Energy Raters & Home Performance Professionals (IAER).
The certification, called the Duct & Envelope Tightness (DET) Verifier, puts individuals on a state-published list of third party professionals, along with the IAER's other HERS and BPI Certified members. Assistance was provided by the Illinois Dept. of Commerce and Economic Opportunity (DCEO) to establish the one-day training curriculum in Illinois, and the IAER received a generous donation of training equipment from Retrotec, a leading maker of blower doors and duct tightness testers.
Scheduled in coordination with building officials across Illinois, the one-day, $250 course will be taught by IAER trainers, and certified DET Verifiers will be Quality Assured on an annual basis by the IAER's HERS Raters and BPI Certified Professionals. The widespread opportunity for professionals, and the common availability of blower door and duct tightness testing providers will put the state of Illinois above most other states with regard to building excellence. The 2012 IECC requires a tight building envelope (the air sealing and insulation shell) and tight ducts, plus dedicated fresh air ventilation- all of these will lead to greater comfort and air quality for occupants, as well as improved durability and energy efficiency.
