Chicago’s Building Energy Rating System

Chicago was the first U.S. city to require building owners to prominently post a building’s energy performance rating, and to share that that rating with potential buyers and/or renters. While the rating system was being introduced, ComEd and Peoples Gas ran extensive complementary incentive and rebate programs that enabled building owners and managers to make energy improvements at little to no cost. Designated a Landmark case study in 2022 by our climate change peer review panel.
