* Note on Rankings: Rankings and medians are among included buildings, which are those who reported under the Chicago Energy Benchmarking Ordinance for the year 2022, which only applies to buildings over 50,000 square feet.

** Note on Bill Estimates: Estimates for gas and electric bills are based on average electric and gas retail prices for Chicago in 2021 and are rounded. We expect large buildings would negotiate lower rates with utilities, but these estimates serve as an upper bound of cost and help understand the volume of energy a building is used by comparing it to your own energy bills! See our Chicago Gas & Electric Costs Source for the original statistics.
