Taipei 101 (Chinese: 台北101 / 臺北101), formerly known as the Taipei World Financial Center, is a landmark skyscraper located in Xinyi District, Taipei, Taiwan. The building ranked officially as the world's tallest from 2004 until the opening of the Burj Khalifa in Dubai in 2010. In July 2011, the building was awarded LEED Platinum certification, the highest award in 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. In 2001, TFCC handed over the entire construction authority to Samsung C&T Corporation to expedite the process and to save KTRT Joint Venture's loss. The construction was finished in 2004. The tower has served as an icon of modern Taiwan ever since its opening.^{[citation needed]} 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.
