The 16,000 people who work in and visit Willis Tower each day could soon be spending less time on their elevator rides in Chicago's tallest building.
A five-year project to upgrade the tower's 83 elevator shafts -- and replace 97 passenger cabs, as some shafts have two-level elevators -- will start in June, according to the building's owner, Blackstone Group's Equity Office, and elevator firm Otis.

This major upgrade is expected to significantly reduce trip times as well as energy consumption (by as much as 30-35%), according to Equity Office and Otis.
The 110-story Willis Tower—once ranked as the world's tallest building for nearly 25 years—hasn't undergone such an enormous overhaul since it was completed in 1973 as Sears Tower.
