The State of Michigan recently passed a new version of the state energy code which is based on the 2015 IECC but with some state specific amendments. The new code is scheduled to start in February 2016.
One of the biggest changes is the requirement that new homes be tested for air infiltration by a certified professional. Some local jurisdictions are requiring testing NOW.
This site has been designed to help builders, code officials, and other interested parties to find a certified individual to conduct their compliance testing.
