Taipei 101 (Chinese: 臺北101; pinyin: Táiběi yī líng yī; stylized as TAIPEI 101), formerly known as the Taipei World Financial Center, is a skyscraper in Taipei, Taiwan. This building was officially classified as the world's tallest from its opening in 2004 until the 2009 completion of the Burj Khalifa in Dubai, UAE. Upon completion, it became the world's first skyscraper to exceed a height of half a kilometer. The elevators that transport passengers from the 5th to the 89th floor in 37 seconds (attaining 60.6 km/h (37.7 mph)) set speed records. In 2011 Taipei 101 received a Platinum rating under the LEED certification system, becoming the tallest and largest green building in the world. The structure regularly appears as an icon of Taipei in international media, and the Taipei 101 fireworks displays are a regular feature of New Year's Eve broadcasts. Taipei 101's postmodernist architectural style evokes traditional Asian aesthetics in a modern structure employing industrial materials. Its design incorporates a number of features that enable the structure to withstand the Pacific Ring of Fire's earthquakes and the region's tropical storms. The tower houses offices, restaurants, and indoor and outdoor observatories. The tower is adjoined by a multilevel shopping mall that has the world's largest ruyi symbol as an exterior feature. Taipei 101 is owned by Taipei Financial Center Corporation. The skyscraper opened on 31 December 2004 to celebrate New Year's Eve.
