Energy Code Information
The Energy Efficient Building Act 20 ILCS 3125On January 29, 2010, the new state law known as The Energy Efficient Building Act 20 ILCS 3125 came into effect. This new law now includes all new residential buildings, additions, alterations, renovations and repairs; previously it only pertained to commercial projects. These projects must now meet all of the code requirements in the 2012 International Energy Conservation Code.

Why are there Building Energy Codes?
The Department of Energy provides a very detailed explanation on the importance of Energy Codes in the United States. From their website: Buildings use 39% of our total energy, two-thirds of our electricity, and one-eighth of our water. Of our total energy usage, transportation uses only 34%, and industry uses only 27%. In light of these fundamental environmental issues, the increasing cost of energy, and our current economic challenges, building energy efficiency is a key component of sound public policy.
