Energy code compliance is a chronically underfunded activity, despite the potential energy savings promised by energy codes. Establishing a utility program that enhances energy codes compliance promotes energy efficiency. Many utilities in the Midwest need creative and rigorous new programs to help meet the Energy Efficiency Portfolios Standards enacted throughout the region. As a national leader inenergy efficiency, Illinois has accepted the challenge. The state Capital Development Board has adopted the 2012 International Energy Conservation Code, and the focus has shifted to achieving compliance with the code.

In 2012, the Department of Commerce and Economic Opportunity (DCEO) embarked on a project aimed at establishing a code compliance program. This effort was dubbed CANDI after the names of the participating utilities and agencies: Commonwealth Edison (ComEd), Ameren Illinois Company (Ameren), Nicor Gas, DCEO and Peoples Light and Coke Company and North Shore Gas (Integrys). The effort had several goals under the premise that because there is one statewide energy codes in Illinois, the program should also be statewide. All investor-owned utilities needed to participate and propose the same approach to the Public Utilities Commission to ensure a consistent approach toward: measuring compliance, converting compliance rates into energy usage and savings, attributing measured energy savings to program, allocating the program costs among the utilities, developing the program elements, determining how to allocate savings between natural gas and electric utilities and calculating cost-effectiveness. These were all issues that need to be addressed. This paper will discuss how these various issues were addressed and how the project was formed into a coherent, comprehensive program.
