The new 2011 Georgia Energy Code, requires a building envelope/duct tightness test for one-and-two family dwellings that are permitted after January 1^st, 2011. We have the required certification and equipments to provide these kinds of testing.

Our compliance division assists contractors by performing the duct blaster and blower door testing and reporting the results. We can also serve as consultant from the beginning of the project to avoid any surprises.In this case, we review building plans, locate critical areas, and advise on enforcing and supervising the work of subcontractors to meet energy code compliance. We then run the testing and complete the form/certificate that must be posted on the electrical panel.  

 Excerpts from the Energy Code:

 Building Envelope Tightness Testing: Section 404.4.2.1

• Building envelope tightness testing is required for all one and two family dwellings and townhouses. This testing must be done by a Certified Duct and Envelope Tightness (DET) Verifier. See Section 402.4.2 of the 2011 GA Amendments to the 2009 IECC for the full requirements.

Sealing Duct Systems: Section 403.2.2

• The joints and seams of all duct systems must be made substantially airtight by means of tapes, mastics, liquid sealants, gasketing or other approved closure systems. Without exception, all closure systems shall have mastic applied that is at least 0.08 inches (2mm) thick.

• Building framing cavities shall not be used as supply or return ducts. All supply and return ducts must be lined with metal, flex duct, duct board, or other material approved in Section M1601 of the IRC.

Duct Tightness Testing: Section 403.2.2

• All new residential structures shall pass either a ‘rough-in’ or ‘post-construction’ duct tightness test. The only exception is if the entire duct system and air handler are located within conditioned space.
