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 email@example.com 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 Info@ChicagoEnergyBenchmarking.org. This correction was prompted by an e-mail from a public user of the dataset. We very much appreciate such messages.
