The Calpine Center is a 453 ft (138m) tall postmodern skyscraper in Downtown Houston, Texas. The building has 33 floors of Class A office space. It is the 30th tallest building in the city. The building has the world headquarters of Calpine. Hines and Prime Asset Management jointly developed the building. Hellmuth, Obata & Kassabaum's Houston office designed the building, and Turner Construction acted as the general contractor. It is connected to the downtown tunnel system. Mark Russell of Studley, a real estate firm, said that the Calpine Center is more efficient than many of the tall office buildings built in Houston in the early 1980s.
