Chicago Energy Benchmarking
Chicago Energy Benchmarking
The Chicago Building Energy Use Benchmarking Ordinance calls on existing municipal, commercial, and residential buildings larger than 50,000 square feet to track whole-building energy use, report to the City annually, and verify data accuracy every three years. The law, which was phased in from 2014-2017, covers less than 1% of Chicago’s buildings, which account for approximately 20% of total energy used by all buildings. For more details, including ordinance text, rules and regulations, and timing, please visit www.CityofChicago.org/EnergyBenchmarking
The ordinance authorizes the City to share property-specific information with the public, beginning with the second year in which a building is required to comply.
The dataset represents self-reported and publicly-available property information by calendar year. Currently, the data includes calendar year 2014 information for 243 properties, calendar year 2015 information for over 1,500 properties, calendar year 2016 information for over 2,700 properties, and calendar year 2017 information for almost 2,800 properties.
The "Data Year" column and filtered views under "More Views" can be used to isolate specific years.

| Reporting Status | reporting_status | reporting_status | Text | Whether the building submitted its report for the Data Year shown. Buildings that did not do so were not listed at all for Data Years through 2017 so all records prior to 2018 will have a value of Submitted. "Temporarily Exempt" means that the building received a one-year, temporary exemption from reporting. "Not Submitted" means that the building did not receive an exemption or submit a report, and is out of compliance. This status could also mean that a report was submitted, but was missing required information, such as whole-building energy use. "Submitted" means the building submitted a report and is in compliance for the Data Year shown. |
