Taipei 101 (Chinese: 臺北101 / 台北101), formerly known as the Taipei World Financial Center, is a landmark supertall skyscraper in Xinyi District, Taipei, Taiwan. The building was officially classified as the world's tallest in 2004, and remained such until the opening of Burj Khalifa in Dubai in 2010. In July 2011, the building was awarded the LEED Platinum certification, the highest award according the Leadership in Energy and Environmental Design (LEED) rating system, and became the tallest and largest green building in the world. Taipei 101 was designed by C.Y. Lee & partners and constructed primarily by KTRT Joint Venture. The construction started in 1999 and finished in 2004. The tower has served as an icon of modern Taiwan ever since its opening. Fireworks launched from Taipei 101 feature prominently in international New Year's Eve broadcasts and the structure appears frequently in travel literature and international media.
Taipei 101 comprises 101 floors above ground and 5 floors underground. The building was architecturally created as a symbol of the evolution of technology and Asian tradition. Its postmodernist approach to style incorporates traditional design elements and gives them modern treatments. The tower is designed to withstand typhoons and earthquakes. A multi-level shopping mall adjoining the tower houses hundreds of stores, restaurants and clubs.
Taipei 101 is owned by Taipei Financial Center Corp. (TFCC) and managed by the International division of Urban Retail Properties Corporation based in Chicago. The name originally planned for the building, Taipei World Financial Center, until 2003, was derived from the name of the owner. The original name in Chinese was literally Taipei International Financial Center (臺北國際金融中心).
