The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Incentives/Policies for Energy Efficiency

Printable Version
Building Energy Code   

Last DSIRE Review: 10/09/2014
Program Overview:
State: Illinois
Incentive Type: Building Energy Code
Eligible Efficiency Technologies: Comprehensive Measures/Whole Building
Applicable Sectors: Commercial, Residential
Residential Code:The Illinois Energy Conservation Code incorporates the 2009 IECC for all residential buildings 3 or fewer stories in height (4 or less if in Chicago). This code is mandatory statewide.
Commercial Code:The Illinois Energy Conservation Code incorporates the 2009 IECC and ASHRAE Standard 90.1-2007 (by reference) for all privately-funded commercial buildings. Standard 90.1-2007 is also required for all publicly-funded commercial buildings. This code is mandatory statewide.
Code Change Cycle:An automatic update provision directs the Capital Development Board to adopt each new version of the IECC within nine months of its publication, with an effective date three months afterwards. The latest code change became effective January 29, 2010. As required by law, the 2012 IECC will take effect on January 1, 2013.

Summary:

Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

Public Act 093-0936 (Illinois Energy Conservation Code for Commercial Buildings) was signed into law in August, 2004. The Illinois Energy Conservation Code for Commercial Buildings became effective April 8, 2006. This law requires all commercial construction for which a building permit application is received by a municipality or county to follow a comprehensive statewide energy conservation code. The Capital Development Board has the authority to create administrative rules, and its most recent rule amendments mandated that the code for commercial buildings follow 2009 International Energy Conservation Code (IECC) (as of August 2009). Municipalities and counties are required to enforce 2009 IECC.

The Energy Efficient Building Act (HB 3987) was signed into law in August 2009. The legislation directed the Illinois Capital Development Board (CDB) to adopt the Illinois Energy Conservation Code, which became effective January 29, 2010. The new statewide code (71 IAC 600) incorporates the 2009 IECC for residential buildings and privately funded commercial buildings and ASHRAE 90.1-2007 for publicly funded commercial buildings (previously, there was not a mandatory residential statewide energy code based on the IECC). An automatic update provision directs the CDB to adopt each subsequent version of the IECC within nine months of its publication, with an effective date three months afterwards. The legislation also removed local home rule jurisdiction over residential energy standards. Local governments are allowed to adopt more stringent energy codes for commercial buildings (but not less stringent). These jurisdictions also may not adopt residential codes more or less stringent than the state code.

Senate Bill 3724, signed into law in August 2012, made some changes to the implementation of future codes, including 2012 IECC. The CDB is now required to adopt new versions of the IECC within one year of its publication and the code is to take effect statewide within 6 months of being adopted. The law includes an exception for the new code, which is expected to be adopted in 2012. The law provides that any code adopted in 2012 will take effect on January 1, 2013.
