DUCT TESTING, BLOWER DOOR TESTING AND CODE COMPLIANCE
New Requirements as of 2016
This year, the state of Connecticut will begin enforcing the 2012 International Energy Conservation Code (IECC) as part of the Connecticut State Building Code for both residential and commercial construction. As part of this code, duct testing is a mandatory process and adhering to tight standards for duct leakage is specified for all new construction and retrofit projects. Testing the building envelope for air leakage with a blower door is also required to ensure the home is not excessively drafty. The newest (2012 IECC) code for envelope leakage and duct leakage is significantly tighter than previous requirements. For example, a home built to meet the new code will need to be almost 60% tighter in terms of envelope air leakage and 50% tighter for air duct leakage than a home built prior to the fall of 2016.
Meeting these stringent specifications and verification tests will be very difficult without extra consideration during construction to make the envelope and duct systems tighter. We offer solutions to help contractors meet code requirements as well as the required verification tests such as blower door and duct blaster. We encourage clients to contact us early in the construction and planning process to discuss strategies for meeting the 2012 IECC requirements.
Duct System Solutions: Duct sealing using traditional manual sealing methods, can be an expensive and problematic proposition. Studies show that even with meticulous applications of mastic and tape, leakage rates are more often than not, fully outside the regulatory requirements. If testing is done after wall construction is completed, poor results would most likely require teardown, re-sealing, and reconstruction.
There is a much easier and less expensive way.
The energy saving professionals at ECS (now CMC Energy Services) are licensed providers of aeroseal duct sealing technology – an innovative duct sealing solution that works from the inside of the ducts to seal leaks.
A Duct Sealing Game Changer
Developed at Lawrence Berkeley National Laboratory by the U.S. Department of Energy, aeroseal technology is a highly effective means of sealing ducts that requires no manual sealing and no deconstruction of walls to access leaks.
This inside/out approach makes aerosealing ductwork ideal for retrofit projects where ducts are hidden or otherwise inaccessible. Used in homes or large buildings – new construction or retrofit projects – aeroseal is so effective at sealing leaks that meeting code compliance is all but guaranteed.
Best of all, the computerized aeroseal process measures results as they happen. At the end of each project a detailed report of the before and after results are created, providing official documentation of code compliance.
