Top 50 Buildings By Square Footage

These are the biggest buildings in our dataset, which should encompass all of the largest buildings in the city that submitted their energy use for 2022. Being a big building does basically guarantee that you use a lot of energy (and emit a lot of CO2), but a lot of big buildings are very energy efficient and use less energy per square foot than much smaller buildings!

Note: Data includes large Chicago buildings with data from 2022, unless explicitly stated otherwise.

Note: This data only includes buildings whose emissions are reported under the Chicago Energy Benchmarking Ordinance(opens in a new tab). According to the City “As of 2016, this list includes all commercial, institutional, and residential buildings larger than 50,000 square feet.” This dataset is also then filtered to only buildings with reported emissions > 1,000 metric tons CO2 equivalent.

The latest year of data is from 2022, but we update the site regularly when new data is available, and some buildings may have failed to report that year, and only have older data available.
