Electrify Chicago

An independent tool for viewing City of Chicago building data

According to the 2022 Chicago Climate Action Plan(opens in a new tab), a whopping 69% of Chicago's emissions come from buildings, making it our biggest challenge and our biggest opportunity as a city to tackle change. At Electrify Chicago, we want to showcase some of the best and worst performing buildings in the city using publicly available data and manual annotations to add building photographs and label multi-building owners like universities.

You can start by looking at Chicago's buildings with the highest greenhouse gas intensity - this means that they use the most energy when adjusted per unit of square foot, so big buildings could actually perform much better than very inefficient small buildings on this metric.

πŸ“° $30 Million In Missed Fines

The City Of Chicago failed to collect $30 million in potential fines from the building benchmarking ordinance, reducing transparency and accountability.

Legislative update! πŸŽ‰

As of late January 2024, legislation is being introduced to require new use more efficient forms of water and space heating, via the Clean And Affordable Buildings Ordinance (CABO), which will reduce the number of highly polluting and inefficient buildings that end up on this site.

If you're in Chicago, write to your alderman to support the CABO! (opens in a new tab)

Chicago Buildings by Greenhouse Gas Intensity

Note: Data only includes large Chicago buildings from 2021, 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 β€œAs 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.

This data is also from 2021, but when new benchmark data is available, we'll update the site.
