About the Iowa Code
On June 1st, 2014, the State of Iowa implemented the 2012 International Energy Conservation Code with Iowa amendments through Iowa Code 661 chapter 303, State Building Code – Requirements for Energy Conservation in Construction. As part of the new 2012 International Energy Conservation Code, blower door testing is required to demonstrate residential building infiltration rate of no more than 4 ACH50 on all new housing starts. Duct tightness testing is required where the air-handler or any portion of the ducts are located outside of the building thermal envelope/pressure boundary or a cavity return is used. For more information on diagnostic energy testing in the new 2012 IECC for more information on the Iowa State Energy Code, visit the Iowa State Fire Marshals Energy Code page.. The Iowa State Fire Marshal’s Office, Building Code Bureau are providing a list of individuals who have taken training or hold certifications related to using building diagnostic equipment including, but not limited to, blower door and duct pressurization equipment. These individuals have received training or certifications demonstrating that they are able to complete blower door testing and/or duct leakage testing in compliance with the 2012 International Energy Conservation Code, Residential Chapters. The State of Iowa does not endorse individual building diagnostic testers. It is recommended that anyone interested in utilizing this list solicit multiple bids and check relevant insurance and licensing of the professionals being considered for building diagnostic tests.
