Chicago Building Code Modernization: Energy Performance and Sustainability Implications

The Chicago Building Code (CBC) was comprehensively revised in 2019. The revised structural requirements are based upon the International Building Code (IBC) - the modern national standard, while maintaining and introducing special Chicago-specific provisions. After 1 August 2020, all new designs submitted for approval by the city will need to conform to the new code.

This paper reviews the changes between the Chicago Building Code (CBC) and International Building Code (IBC)'s updated and previous versions to assist project teams in making informed early-phase design decisions on new-construction and renovation commercial projects.
