  • Illinois Residential Energy Conservation Code updated

    On January 1, 2013, the State of Illinois implemented the 2012 Illinois Energy Conservation Code. The update is based on the 2012 International Energy Conservation Code with Illinois amendments through the Illinois Energy Efficient Building Act.

     

    For example, the new code requires R-49 ceiling insulation, R-20 in the walls and R-19 for insulating the floors.

     

    As part of the new energy code, blower door testing is required to demon­strate a building infiltration rate of no more than 5 ACH50 (the hourly air change rate at a pressure difference of 50 Pascals between inside and outside.) Duct tightness ­testing is required where the air-handler or any portion of the ducts are located outside of the building thermal envelope or pressure boundary.

    The Illinois Department of Commerce and Economic Opportunity (DCEO) and the Midwest Energy Efficiency Alliance (MEEA) are providing a list of individuals who have taken training or hold cer­tifications related to using ­building diagnostic equipment. These individuals have received training or certifications demon­strating that they are able to complete blower door testing and/or duct ­leakage testing in compliance with the 2012 Illinois Energy Conservation Code. The State of Illinois does not endorse ­individual building diagnostic testers. It is recommended that anyone interested in utilizing this list solicit multiple bids and check relevant insurance and ­licensing of the professionals being considered for building diagnostic tests.
