Both of those steel and glass skyscrapers opened in 2009.

On the left (westernmost) is 300 N LaSalle Street. The official website says the building is pre-certified for LEED. This really means someone looked at the design specs and said it means certification. But designs change and I can’t yet find this project on the U.S. Green Building Council’s Certified Projects list.

On the right (easternmost) is 353 N Clark Street. The developer, South Parcel Development, sought LEED Silver certification for Core & Shell but received one better: Gold.
