These buildings are the largest consumers of fossil gas (methane) in the city. Fossil gas in these buildings is typically used for heating gas and water, and since electrifying the grid won't clean up these emissions it's an important set of buildings to focus on!
Note: Data From Large Buildings in 2023
Note: This data only includes buildings whose emissions
are reported under the
Chicago Energy Benchmarking Ordinance
. According to the City “As of 2016, this list includes all
commercial, institutional, and residential buildings larger than 50,000
square feet.”
The latest year of data is from 2023, 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.
Additionally, note that all tons specified are metric tons.
