On November 21st, 2017, 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. 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 the time of listing the property for lease or sale. The new rating system goes into effect in 2019.
The information in this dataset is used by the building owners / managers or other building representatives to determine if the property needs to comply by the annual deadline of June 1st. This dataset can also be used to look up for property’s unique 6-digit Chicago Energy Benchmarking ID, which is required for compliance.
The Energy Benchmarking Ordinance calls on existing municipal, commercial, and residential buildings larger than 50,000 square feet to track whole-building energy use, report to the City annually, and verify data accuracy every three years. The law, which phases in from 2014-2017, covers less than 1% of Chicago’s buildings, which account for approximately 20% of total energy used by all buildings. Note that the ordinance authorizes the City to make individual building data readily-available to the public, beginning with the second year in which a building is covered. The Covered Buildings List is distinct from the publicly-shared energy use data, and does not include energy use or any other information reported in the benchmarking process.
