Illinois Regulations

Regulatory Update

In a 32-7 vote, the Chicago Energy Use Benchmarking Ordinance was turned into law in 2013. The ordinance subjects all commercial, residential, and government buildings occupying more than 50,000 sq. ft. to an annual energy performance evaluation supported by the ENERGY STAR Portfolio Manager. The law covers more than 900 million sq. ft. of Chicago real estate, whose energy consumption and performance scores will be posted annually to a municipal website.

The city of Evanston passed an energy and water benchmarking ordinance in December of 2016 requiring city buildings 10,000 square feet and larger, and privately-owned buildings 20,000 square feet and larger (excluding condos) to report annual energy and water consumption. Privately-owned buildings 100,000 square feet and larger began reporting on June 30, 2017 and smaller building sizes phased in over the next 2 years.

Meanwhile, the State of Illinois is busy working on a statewide benchmarking pilot of its own, leveraging assistance from the Midwest Energy Efficiency Alliance (MEEA).
