Notes on the State's Residential Code:
On Friday, August 28, Illinois’ Governor Pat Quinn signed the Energy Efficient Building Act into law. The Act established a statewide residential energy code, which requires that newly constructed residential buildings meet the minimum standards set forth in the most recent version of the International Energy Conservation Code (2009 IECC). The Illinois Capital Development Board (CDB) must now be review and adopt the code though an administrative proceeding. The CDB has until October 8th, 2009 to adopt the new energy code, and it will take effect within three months thereafter. A schedule for CDB procedures has not yet been released.
Notes on the State's Commercial Code:
The 2009 IECC references ASHRAE Standard 90.1-2007 as a means for compliance. COMcheck currently has 90.1-07 standard a code option. We are expecting to have a new release of COMcheck with the 2009 IECC code option by the beginning of November 2009.
As of August 18, 2009 the Illinois Energy Conservation Code for Commercial Buildings is the 2009 International Energy Conservation Code.
Approximate Stringency:
