New Energy Code

Starting on 1 January 2011, all new homes in Georgia permitted for construction will have to get a Blower Door Test for infiltration.

The result must be less than 7 air changes per hour at 50 Pascals (ACH50).

The 2009 IECC also requires ducts outside the building envelope (in unconditioned spaces) to be tested for leakage. The Georgia energy code requires that the duct leakage outside the envelope be less than 8 cubic feet per minute per 100 square feet of conditioned floor area if tested after construction, 6 cfm/100 ft2 if tested after rough-in.

This level of air tightness is not hard to achieve but home builders will need to have their homes verified by a certified DET Verifier per the new diagnostic testing requirements for new homes by the 2009 IECC Georgia amendments.

Only a Certified Duct & Envelope Tightness (DET) Verifier will be allowed to do this testing. Our company is Certified to perform and issue a DET Verification letter for you to obtain a Certificate of Occupancy.
