Gensler announced that the world’s second tallest skyscraper has been topped out in Shanghai. The twisting, mixed-use Shanghai Tower soars up to 632 meters – a height only eclipsed by the the Burj Khalifa in Dubai. The tower’s cleverly designed facade reduces wind load by 24 percent during typhoons, and sky gardens at the apex mimic traditional open courtyards.
The twisting form reduces the load by 24% during typhoons and also slashed construction costs by a whopping $58 million. The building is organized in nine vertical zones that distribute heating, cooling and water more efficiently, reducing these loads, as well as the costs of maintaining interior comfort. Sky gardens crown the mammoth building alongside observation decks and cultural facilities, while retail facilities are located at the base, with offices spread out between. The tower will open in 2014.
