* Note on Rankings: Rankings and medians are among included buildings, which are those who reported under the Chicago Energy Benchmarking Ordinance for the year 2022, which only applies to buildings over 50,000 square feet.

** Note on Bill Estimates: Estimates for gas and electric bills are based on average electric and gas retail prices for Chicago in 2021 and are rounded. We expect large buildings would negotiate lower rates with utilities, but these estimates serve as an upper bound of cost and help understand the volume of energy a building is used by comparing it to your own energy bills! See our Chicago Gas & Electric Costs Source (opens in a new tab) for the original statistics.

What Should We Do About This?

Practically every building has room to improve with energy efficiency upgrades like insulation, switching to ENERGY STAR rated appliances, and more, but for any buildings with large natural gas use, we recommend one thing: electrify!

In other words, buildings should look to move all on-site uses of fossil fuels (including space heating, water heating, and cooking) to electrically powered systems like industrial grade heat pumps, heat pump water heaters, and induction stoves. With Illinois' current electric supply, just using the same amount of energy from electricity, rather than natural gas (aka methane) will dramatically reduce greenhouse gas emissions. This is because Illinois' grid in 2020 was already 67% carbon-free (see Illinois - Power | DecarbMyState (opens in a new tab)). This has already been done across the country with a variety of buildings, large and small, like the Hotel Marcel (opens in a new tab).

You can help make this a reality by talking to building owners and letting them know that a building's emissions are important to you, and that you want to see their building become fully electric and stop emitting greenhouse gases. Particularly for buildings you have a financial stake in (like your university, work, condo building, or apartment building) your voice in concert with your fellow building users can have a huge impact.
