Illinois is now one of the 29 states that have passed the 2009 or 2012 International Energy Conservation Code (IECC). What does this mean for Illinois residents and business owners? All duct systems outside of conditioned space must be verified for proper sealing by a pressure test.  As part of this new energy code, blower door testing is required to demonstrate a building infiltration rate of no more than 5 ACH50. This code is different in that the revision takes away the option for visual inspection. Building Envelope Testing is required in the 2012 IECC.

In Illinois, most municipalities are looking for trained professionals with credentials to complete this testing. The Building Energy Experts are those trained professionals.

What a delight and pleasure it is to be writing this letter to you. I contracted Building Energy Experts for this project. The crew was kind, courteous, respectful, patient, and easy to coordinate with, as well as knowledgeable. I highly recommend them without any reservations on my part.
