The Duke Energy Center is a 786 feet (240 m) tall, 48-floor (54 floors including mechanical floors) skyscraper in Charlotte, North Carolina. When completed in 2010, it was the largest building in Charlotte (in square footage), second tallest building in Charlotte, and the tallest in the world to use precast double tees built by Prestress of the Carolinas. The building is named for its anchor tenant, Duke Energy, and both the tower and the adjacent cultural arts campus are owned by Wells Fargo.
Sonnenschein will use 35,000 square feet (3,300 m2) on the 34th and 35th floors and Deloitte will use 82,000 square feet (7,600 m2).
Originally, the building was to be known as the Wachovia Corporate Center. It was to replace One Wachovia Center as the headquarters of Wachovia. Wachovia was to occupy 450,000 square feet (42,000 m2) of the 1,500,000 square feet (140,000 m2) tower. Wells Fargo plans to use five of its 14 floors.(Wikipedia)
