Energy Benchmarking Correction

We have reloaded the 2019 Data Reported in 2020 data in the Chicago Energy Benchmarking dataset due to errors discovered in the original data.

Partly to facilitate the update process and partly because it may be useful for other purposes, we have added a Row_ID column to the dataset. It is simply the combination of the Data Year and ID (property ID) columns. Within any year, the ID column alone should be unique.

As always, please feel free to contact us at or @ChicagoCDO with any questions, comments, or concerns related to the datasets. For subject matter questions about the Energy Benchmarking datasets please contact that program at This correction was prompted by an e-mail from a public user of the dataset. We very much appreciate such messages.
