Illinois became the first state in the country to adopt the 2012 International Energy Conservation Code as its mandatory statewide building energy code. The code takes effect on January  1, 2013. The 2012 IECC was adopted in its entirety, with minor adjustments on the residential code, after the Illinois Joint Committee on Administrative Rules approved the new rules on December 11, 2012.
