Chicago is the greenest U.S. city to work in for the second year running, with about 70 percent of its office space now certified for environmental efficiency, a new study shows.
The Windy City’s percentage of green offices is up from about 66 percent last year, placing it ahead of San Francisco, Atlanta, Los Angeles and Minneapolis/St. Paul, according to an annual ranking by CBRE Group Inc. and Maastricht University. The study tracks buildings in 30 of the biggest U.S. real estate markets that are LEED or Energy Star certified.
