Note: Buildings are marked as reporting when we have greenhouse gas intensity values for them, but some buildings are missing GHG intensity values but have reported the underlying energy use data, but we're unsure why this is the case.

* 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!
