Permit applications that are started on or after June 1, 2019, which was two days ago, must comply with the Chicago Energy Conservation Code. The energy code is based on the 2018 edition of the International Energy Conservation Code (IECC).

To read the updated code, access the IECC 2018 on the International Codes Council website and review the modifications made by the ordinance for the updated Chicago Building Code (SO2019-1452, adopted April 10, 2019). Skip to page 579 of the updated CBC to read the modifications.

The updated Chicago Energy Conservation Code will soon live as Title 14N in the Municipal Code of Chicago and will be added to the Amlegal website that hosts all City codes. A full document will be published this summer.

Permit applications must come with the 2019 compliance statement (residential buildings up to 4 stories, all other buildings). Find more info on the Department of Buildings energy conservation requirements page.

This Chicago Energy Conservation Code will be fully integrated in the updated Chicago Building Code (CBC) when the updated CBC takes effect later this year. The updated CBC becomes optional for use on permit applications starting December 1, 2019, and will be mandatory on August 1, 2020.
