NEW! 2017 Chicago Energy Benchmarking Report & Data Release

On February 9, 2018 the City of Chicago released its 2017 Chicago Energy Benchmarking Report and Infographic. The City also posted energy data for over 2,700 properties, as authorized under the Chicago Energy Benchmarking Ordinance.

Chicago Energy Rating System

On November 21st, the Chicago City Council approved updates to the Chicago Energy Benchmarking Ordinance in order to improve the visibility and transparency of the reported information, while also making the information easier to understand. A summary of the changes and some of the benefits are provided in this summary, and this FAQ document provides answers to frequently asked questions. The full ordinance can be downloaded here.

In summary, the updates will create a new Chicago Energy Rating system for buildings required to benchmark. Properties in compliance with benchmarking reporting will receive between one and four stars on a four-star rating system, based on their 1-100 ENERGY STAR score. Properties with one, two, or three stars will be able to earn an additional star if they have improved by at least 10 points in the past two reporting years. Building owners will be required to post their rating in a prominent location, and to share the rating at time of listing the property for lease or sale. The new rating system goes into effect in 2019.

The initial ratings would based on the following scale:

  • Zero stars: Out of compliance with energy benchmarking (no report sent to the City) 
  • One star: 1-40 points
  • Two stars: 41-60 points OR a score of 11-40 points and a 10 point improvement in the past 2 years
  • Three stars: 61-80 points OR a score of 41-60 points and a 10 point improvement in the past 2 years
  • Four stars: 81-100 points OR a score of 61-80 points and a 10 point improvement in the past 2 years

 The ratings would be issued by the City and would be posted on each building required to benchmark; a draft mock-up of the rating placard is provided below.

“Energy efficiency is not a passing fad; it has become a core value and operating principle for many of Chicago’s largest corporate tenants, condo owners, and residential tenants.”

– Commercial and Residential Real Estate Manager


“Energy [benchmarking and] disclosure [across our management portfolio of more than 1,000 buildings] has helped [condominium] board members feel comfortable making decisions to improve efficiency because they have more accurate data on which to base their decision. They are also able to better quantify the investment and return they will generate. We have found that the more informed owners are about their building’s environmental impact, the more empowered they are to improve it.”

– Residential Portfolio Director of Operations
