Chicago's 132 Fully Gas Free Buildings

These buildings are already all-electric, and feature some of the most famous buildings in the city! If even the John Hancock center or Marina Towers can run off of only electricity, your building can too.

Note: This list is of buildings that use neither natural gas nor a district steam system, since all district steam systems in the city are currently powered by burning natural gas (to the best of our knowledge).

Note: Data From Large Buildings in 2022

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.” 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.

Additionally, note that all tons specified are metric tons.
