US-based Adrian Smith + Gordon Gill Architecture (AS+GG) has won an international competition to design Qintai Center in Wuhan, Hubei Province, China.
Qintai Center will be a 248m corporate headquarters tower and related podium structure in Wuhan.
The 146,000m² centre will feature a hotel and office space to be occupied by the client, Hubei Tobacco Company, and other tenants.
The tower will be linked through a plaza and a pedestrian bridge to the podium, which will feature retail, restaurants as and a conference centre with a ballroom.
A lounge and restaurants will feature at the top of the tower, offering views of the surrounding cityscape.
The facade bends outward in a diagonal line that rises northwest up the tower; this will be adjusted to optimise self-shading and minimise the structure’s solar heat gain.
Smaller floor plates of the tower will allow daylight harvesting to reduce the building’s energy consumption for artificial lighting.
The building will be orientated in such a way that it offers views of Wuhan’s great bodies of water, including Moon Lake to the east and the nearby Hanshui River to the north.
Qintai Center will be surrounded by a series of pools and other water features. The water features will be performative elements of the design, making the air feel fresher in Wuhan’s hot climate.
The water used by performative elements will come from stormwater and/or recovered condensate from the complex.
Sustainable features of the centre include solar hot water roof panels, natural ventilation systems, an exterior wall featuring passive shading and vertical fins on the east and west facades.
AS+GG design partner Adrian Smith said, "The genesis of the form in the competition phase related to the guzheng, a traditional Chinese musical instrument similar to a zither, featuring strings that are stretched over pegs that form a raised S curve over a rectangular wooden frame."
In June 2011, AS+GG had won an international competition to design Wuhan Greenland Center in China.
