Illinois Officially Adopts 2009 IECC and ASHRAE 90.1-2007 Statewide
As directed by legislation approved in August, the Illinois Capital Development Board (CDB) has officially adopted the Illinois Energy Conservation Code, which became effective January 29. 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).The legislation also removed local home rule jurisdiction over residential energy standards. Local governments are allowed to adopt more stringent codes for commercial buildings, but may not adopt residential codes more or less stringent than the state code (exemptions to go above the state code are made for municipalities that adopted at least the 2006 IECC before May 2009 or have more than 1,000,000 residents).
