illi News/10184742

Mayor Lori E. Lightfoot, Alderwoman Maria Hadden, and the Chicago Department of Buildings today introduced a substitute ordinance to modernize the city's heating and cooling ordinance and better account for extreme weather events. The substitute ordinance, which passed unanimously out of the City Council Committee on Zoning, Landmarks and Building Standards, will be heard by the full City Council on June 22.

"As extreme weather events become more frequent and more severe due to climate change, our construction codes must allow for flexibility in cooling and heating systems to protect the residents who live and work within them," said Mayor Lightfoot. "These new cooling requirements are an important step forward in keeping all of our residents safe, particularly those most vulnerable to extreme heat, while improving their quality of life."

"I commend the leadership of Mayor Lightfoot and Alderwoman Hadden on this vital legislation and look forward to working with property owners and property managers to implement these safety and quality of life measures," said Matthew Beaudet, Commissioner of the Department of Buildings.
