The Chicago Energy Conservation Code (CECC) requires residential buildings applying for building permits to comply with energy efficient measures which go beyond those required by the [http://www.dsireusa.org/library/includes/incentive2.cfm?Incentive_Code=I... Illinois Building Energy Code]. The applicability of the CECC to commercial construction was superseded when the state of Illinois adopted the more stringent IECC 2009 model code. Illinois state law in 2009 also mandated the IECC 2009 model code for residential buildings, but allowed for cities of home rule and more than 1,000,000 people (namely, Chicago) to adopt more stringent rules.

The CECC establishes standards to minimize solar energy absorbed by building roofs, a condition known as the '''''urban heat island effect'''''. Increased reflecting capacity of individual and aggregate buildings has been associated with cooler temperatures. In general, the energy conservation code establishes minimum standards for fenestration, insulation and roof reflectance. Refer to the Chicago Energy Conservation Code for detailed information on compliance standards for various roof slopes.

Compliance with the code is required for '''''residential buildings that apply for a building permit''''' through the city of Chicago's Department of Buildings. This includes all new buildings or additions to existing buildings, all occupancy changes in existing buildings, all conversions of existing unconditioned space to conditioned space and the replacement of an entire building system, including building envelope components such as the exterior wall finish, roofing membrane, windows, and doors, or the entire mechanical, refrigeration, service water heating, electrical or lighting system.

Building permits for any of these types of projects are required to include a statement of compliance from an architect or engineer listed as a Registered Energy Professional for Residential Buildings on the [http://www.cityofchicago.org/city/en/depts/bldgs/supp_info/chicago_energ... City of Chicago's Energy Conservation Code website]. Compliance documents, such as forms and worksheets, can also be found on the Department's CECC website.
