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.[1][2] It is the 30th tallest building in the city.[citation needed] The building has the world headquarters of Calpine Corporation.[3] Hines and Prime Asset Management jointly developed the building. The Houston office of HOK designed the building, and Turner Construction acted as the general contractor.[2] 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.[4]


Originally Calpine intended to lease 300,000 square feet (28,000 m2) of space. By February 2003 Calpine announced that it would sublease some of the space to other firms.[5] The Calpine Center was scheduled for completion at the end of 2003. In July 2003 the space was 82% booked for occupation. Calpine and Burlington Resources, another energy company, leased space in the building; each company agreed to lease 250,000 square feet (23,000 m2) of space. In addition Jones Day agreed to lease over 50,000 square feet (4,600 m2).[1] The building opened on Monday November 10, 2003. Other tenants that had occupied the building by its opening included Cheniere Energy Inc. and Hines's southwest region development office.[2] In 2004 Avalon Advisors LP agreed to lease 9,385 square feet (871.9 m2) of space in the building, bringing its occupancy level to 86%.[6]
