View Data Notes & Disclaimers
* Note on Rankings: Rankings and medians are among included buildings, which are those who reported under the Chicago Energy Benchmarking Ordinance for the year 2023, 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!

Chicago Gas & Electric Costs Source
for the original statistics.
