“This ordinance will help to capture the information to enable better informed real estate decisions and unlock the market for energy efficiency.  We believe that this ordinance addresses key business and policy priorities in our sector, including saving money, creating local jobs, protecting our health, and promot[ing] Chicago’s position as a leading sustainable city to attract new business and succeed in the global market place.”

– Commercial and Residential Real Estate Management Executive


“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

In September 2013, Mayor Emanuel and Chicago’s City Council adopted a building energy benchmarking ordinance to raise awareness of energy performance through information and transparency, with the goal of unlocking energy and cost savings opportunities for businesses and residents.

Chicago's Building Energy Use Benchmarking Ordinance (ordinance textrules & regulations) calls on existing commercial, institutional, 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 covers less than 1% of Chicago’s buildings, which account for ~20% of total energy used by all buildings.

Improving energy efficiency is a key element of Sustainable Chicago 2015, Mayor Emanuel’s action agenda to make Chicago more livable, competitive, and sustainable.


2014 Chicago Energy Benchmarking


Thank you to all Chicago building owners, managers, partners, and service providers who contributed to a successful second year of ordinance implementation!

2015 Chicago Building Energy Benchmarking analysis is now available:  

Click here to access all Chicago Energy Benchmarking results and data for 2014 and 2015.

Note: 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.  Identifying information, whole-building energy use by fuel source, energy performance metrics, and greenhouse gas metrics are now available for commercial and institutional buildings larger than 250,000 square feet.



Ordinance Requirements:

The Chicago Energy Benchmarking Ordinance focuses on creating information that will enable better decision-making.  It does not require buildings to make any mandatory investments.  The ordinance has three parts:

  1. Benchmark energy use (annually): Covered buildings will track energy consumption and basic building characteristics using ENERGY STAR Portfolio Manager, a free online tool offered by the US EPA.
  2. Verify energy data (every 3 years): In the first year in which buildings benchmark, and every third year thereafter, buildings will have energy and building data reviewed by an in-house or 3rd-party professional with a license or training credential recognized by the City (details on recognized credentials follow below).
  3. Report to the City (annually): Using the 2015 Chicago Energy Benchmarking Reporting Link, covered buildings will report basic building and energy data to the City of Chicago, using the ENERGY STAR Portfolio Manager tool.

The City will report each year on aggregate energy efficiency trends, and the ordinance authorizes the City to share building-specific data with the public beginning with buildings' second year of reported information.

Covered Buildings:

The ordinance applies to existing municipal, commercial, and residential buildings larger than 50,000 square feet, with first-time compliance deadlines based on size and occupancy use.

  • Building Size:  Building size is defined as gross square footage - the total number of square feet measured between the exterior fixed walls of a building.  This includes common space, private space, mechanical or electrical rooms, and interior parking.
  • Building Occupancy Use: Building occupancy is determined by how space is used within a building.  The benchmarking ordinance applies to commercial, residential, institutional, assembly, schools, businesses, and mercantile units, as well as spaces with mixed occupancy or auxiliary uses.
  • Mixed-Use Residential Buildings: For the purpose of determining initial compliance timing, any covered building with 10% or more of its gross square footage classified as Class A residential units (as defined by the Municipal Code of Chicago, Chapter 13-56) should adhere to the compliance deadlines for residential buildings.
  • Non-Covered Occupancy Uses: The benchmarking ordinance does not apply to buildings with more than 10% or more of gross square footage classified as Class D open air assembly units, Class G industrial units, Class H storage units, Class I hazardous use units, or Class J miscellaneous buildings and structures (as defined by the Municipal Code of Chicago, Chapter 13-56).

Using the best available information, the City will notify covered buildings in the years in which they are required to comply.  Additional information on building occupancy classifications is available in the Municipal Code of Chicago Chapter 13-56.

Compliance Deadlines:

The Chicago Energy Benchmarking ordinance will phase-in from 2014-2016, with an annual deadline of June 1st.  After a covered building's first annual compliance deadline, it must benchmark and report every year thereafter, with data verification every third year.  

Compliance timing is based on building size and occupancy use, according to the following schedule:

  • 2014: Commercial & institutional buildings ≥ 250,000 square feet
  • 2015: Commercial & institutional buildings 50,000 – 250,000 square feet; residential buildings ≥ 250,000 square feet 
  • 2016: Commercial, institutional, & residential buildings ≥ 50,000 – 250,000 square feet



In 2015, the Chicago Energy Benchmarking Ordinance applied to commercial and institutional buildings larger than 50,000 square feet and residential buildings larger than 250,000 square feet.  In 2016, all commercial, institutional, and residential buildings larger than 50,000 square feet will be required to comply.

US EPA ENERGY STARUsing ENERGY STAR Portfolio Manager: To facilitate building benchmarking, data verification, and reporting, the Chicago Energy Benchmarking Ordinance uses ENERGY STAR Portfolio Manager, a free online software tool developed by the US Environmental Protection Agency (US EPA).

In addition to the Chicago Energy Benchmarking Guide and other support materials listed above, the US EPA provides free online resources to help buildings get started with energy benchmarking.

Please visit the Chicago Energy Benchmarking Training & Building Support page for additional materials and how-to videos on the Portfolio Manager software tool and the entire ENERGY STAR Program.

Once buildings have benchmarked energy use and verified data if this is the first year of compliance, please click here to report 2015 Chicago Energy Benchmarking Data (link will prompt users to log in through ENERGY STAR Portfolio Manager).

Fulfilling the Data Verification Requirement / Finding A Recognized Data Verifier:  To ensure that data is being tracked and reported correctly, covered buildings must have their energy and building data reviewed and verified every three years. 

The ENERGY STAR Portfolio Manager Data Verification Checklist, signed by a trained individual whose professional license or training program credential is recognized by the City, serves as proof of data verification.  Data verifier information must be entered into the "Property Notes" section of each building's Portfolio Manager profile, as described in the Chicago Energy Benchmarking Guide and Compliance Checklist.  

Data verifiers may be in-house building staff members or 3rd party professionals.

The City of Chicago currently recognizes the following data verifier licenses and training program credentials:

Additional data verifier licenses and training program credentials may be recognized by the City and posted to this website.

The City also recognizes buildings that have achieved ENERGY STAR Certification by the US Environmental Protection Agency as fulfilling the data verification requirement, provided that the building's ENERGY STAR certified data include at least six months of the calendar year for which Chicago Energy Benchmarking data verification is required.

Some covered buildings may be eligible for pro-bono data verification through the U.S. Green Building Council's Illinois Chapter, ASHRAE Illinois, AIA-Chicago, and local volunteers.  Please scroll down to "Free Training & Building Support" for additional information on pro-bono data verification opportunities and other building support.

Directory of Benchmarking Service Providers:  The US Green Building Council's Illinois Chapter (USGBC-IL) maintains an online directory of companies that offer fee-for-service support for energy benchmarking, data verification, and other efficiency efforts.  USGBC-IL created this directory to help interested buildings find firms that provide benchmarking-related services. As a reminder, the Chicago Energy Benchmarking Ordinance does not require covered buildings to hire outside support (please refer to the "Fulfilling the Data Verification Requirement" section of this webpage and benchmarking guidance materials for additional details).

Note: This directory contains self-reported service provider information.  Buildings should exercise all due diligence when selecting an energy service provider. The City of Chicago does not guarantee the quality or pricing of the work provided by these firms, and the firms listed in the directory do not have any affiliation with the City of Chicago.

Please click here to access USGBC-IL's Benchmarking Service Provider Directory.

Reporting to the City: Once a building has been benchmarked in Portfolio Manager and data has been verified, covered buildings must submit their annual report to the City of Chicago using the 2015 Chicago Energy Benchmarking Reporting Link.

After clicking the reporting link, users will be prompted to log into their Portfolio Manager account, which will guide them through several simple reporting steps (including selecting the building(s) on which to report, reviewing the information to be reported, and sharing that information with the City of Chicago).
