Illinois Envelope Leakage Testing (DET Verification)

Effective January 1st, 2013 all new construction & extensive renovations fall under the new Illinois Energy Conservation Code as amended (AKA as the Energy Efficient Building Act (EEB ACT) [20ILCS 3125] that requires “DET Verification” (or more commonly known as Duct & Envelope Tightness Verification) be completed. For the “envelope portion” this requires a blower door test utilizing either a single point test or multi-point test done by a certified individual which cannot exceed 5 ACH (air changes per hour).

With our commercial grade equipment you also don’t have to worry about the size of the house or commercial building not being able to be tested. Blower Door Testing Checklist for Builders
