The Shanghai Tower (Chinese: 上海中心大厦; pinyin: Shànghǎi zhōngxīn dàshà) is a supertall skyscraper designed by Gensler and recently under construction[3] in the Pudong District of Shanghai. It will be the tallest of the group of three supertalls in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. Upon completion, the building will rise approximately 632 metres (2,073 ft), have 128 stories, and contain an area of 380,000 m2 (4,090,000 sq ft).[4][5][6] It will be the tallest building in China[7], and the second tallest in the world, surpassed only by the Burj Khalifa in Dubai.

Planning

Planning models for the Lujiazui financial district dating back to 1993 show plans for three supertall skyscrapers all next to each other.[8] Two have already been built; the Jin Mao Building was completed in 1998, and the Shanghai World Financial Center in 2008.

Competition

After numerous designs were submitted by many architectural firms, two design proposals reached the final in early 2008, both 580 m tall.[9] An innovative design by Marshall Strabala of Gensler was chosen in June 2008,[10] where the building twists as it rises and is surrounded by an outer glass curtain wall.

Design

The tower will be organized as nine cylindrical buildings stacked atop each other, enclosed by the glass façade's inner layer.[1] Between that and the outer layer, which twists as it rises, nine indoor zones will provide public space for visitors.[1][7]Each of these nine areas will have its own atrium featuring gardens, cafes, restaurants and retail space and provide 360 degree views of the city. These “sky gardens” will cut down the time needed for people to travel on the building elevators and provide visitors a place to meet, eat and shop. [11] Both layers of the façade will be transparent, and retail and event spaces will be provided at the tower's base.[1] The tower will feature the world's highest non-enclosed observation deck.

Director of Design Marshall Strabala told E-Architect.co.uk architectural news website that Shanghai Tower will represent "China's dynamic future." "It will be an impressive building where China looks ahead to both the future of this bustling and ever-changing metropolis, but also to the future of the dynamic Chinese spirit. There will be no other such unique and well-conceived tower in the world," said Strabala.[12]

Sustainability

The design of the glass façade is described to be able to reduce wind loads on the building by 24%, meaning less construction materials are needed, and the twisting feature will collect rainwater to be used for the tower's air conditioning and heating systems. Wind turbines will generate power for the building. According to E-Architect.co.uk, it will be the first super-tall (300 metres or taller) double-skin building in the world, acting much like a "thermos bottle," says Strabala, to insulate it and save energy.[12]

In recognition of the Shanghai Tower’s outstanding “green” building design, US Commerce Secretary Gary Locke presented a “Certificate of Achievement” to the tower’s developer in May 2010. He said that the sustainable design of the Shanghai Tower gives “us a glimpse of the future of clean energy and how U.S. and Chinese companies are working together to make that future a reality.”[13]

The owners of the future Shanghai Tower hope to be awarded certifications from the China Green Building Committee and the U.S. Green Building Council for the building's sustainable design.[1]

Construction

During 2008, the site was prepared for construction,[14][15] in preparation for the groundbreaking ceremony held on 29 November 2008.[3] The tower has passed an environmental impact study.[6] Construction of the tower will use sustainable techniques to make the building environmentally friendly and reduce energy usage.[7]

The current block assigned for the Shanghai Tower, Z3-2, was for a short time a driving range, before the site was cleared for preparation.[9]

The building is planned for completion in 2014.[1]
