Due to some very recent legislation on the Governor’s desk, implementation of the International Energy Conservation Code (IECC) by the state of Illinois will be moved to January 1, 2013.
Illinois will soon become one of five states in the USA to implement the latest version of internationally-agreed upon energy code standard, the International Energy Conservation Code (IECC). This raises the bar in construction design for residential and commercial structures, and as a result, architects / engineers / contractors building to the new code will be affordably offer a choice to their clients for pursuing several above-code certifications such as Energy Star and LEED without too much additional effort or cost.
The new energy code includes mandatory blower-door testing for building air leakage (less than <5.0 ACH at 50 pascals), which will measure how well contractors have sealed up penetrations between the outdoors and indoor conditioned space. This testing is required for all projects permitted after July 1 in municipalities across the state of Illinois. Other aspects such as requiring hot water pipe insulation and mechanical ventilation are new items that projects will need to implement.

So, how do IECC 2012 requirements relate to voluntary above-code programs like Energy Star, LEED and Passive House? Pretty well actually. AES has assembled a matrix identifying several energy-related items as written in the code and indicated what the impact or requirements would be in one of these above-code third-party green certification programs.

What does this mean? Well just by building to code, Illinois projects will be very close to meeting the Energy Star for Homes program requirements, and will score very well in programs that require Energy Star version 3 such as LEED or Green Communities. Other green programs that don’t require Energy Star, such as National Green Building Standard or Chicago Green Homes program will also heavily reward these projects.
LEED for Homes will be requiring Energy Star version 3 in 2014, so right now a project can still earn LEED certification by building to Energy Star version 2 requirements which should be easily met on any home that meets IECC 2012. Take advantage of this sweet spot by attending a LEED workshop, or sign up to earn LEED certification today!
