The Chicago office of Skidmore, Owings & Merrill LLP (SOM) has announced that it has won the right to design the Greenland Group Suzhou Center in Wujiang, China. The 75-level, 1,174-foot tower is designed to accommodate a mixed-use program including office, service apartments, hotel and retail on a site measuring more than 398,000 square feet.
Situated along Taihu Lake in the Jiangsu Province of China, the building’s curved, tapered form unifies the office, hotel and residential uses within a single volume. The tower features a 30-story tall operable window corresponding to the hotel and residential floors, said to help drive the environmental performance of the development.
High performance design engineering has been integrated into its design. The Wujiang Greenland Tower’s composite core and outrigger structural system use proven cost-effective construction techniques, while its split-core configuration of the upper floors increases the efficiency of the building structure. By placing half of the building core program on each side of the lobby and interconnecting them with structural steel braces, the combined core becomes more effective than a typical center core system while also creating a tall lobby space within.
The atrium, a key design feature of the building, maximizes daylight penetration, facilitates mixed mode ventilation in the lobbies and public spaces, and acts as a fresh air supply source for the tower. The building is oriented to harness both the stack effect and prevailing winds via the east and west façades of the atrium.
Major high performance energy saving strategies include a high performance façade, utilizing cooler outside air at higher levels for natural ventilation of the atrium, natural light harvesting using daylight responsive controls, lighting energy optimization using efficient fixtures and occupant controls, energy recovery systems, demand controlled ventilation, and an onsite energy center with combined heat and power plant to capitalize on the overall load diversity of the development.
The Greenland Group Suzhou Center is SOM Chicago’s sixth project with the Greenland Group. The firm’s work began with Zifeng Tower, formerly Nanjing Greenland Financial Center, in Nanjing, China and was completed in 2009. Five additional projects designed by Wimer for the Greenland Group are the 56-story Zhengzhou Greenland Plaza in Zhengzhou, China, the 59-story Jiangxi Nanchang Greenland Central Plaza, Parcel A in Nanchang, China, the 56-story Nanchang Zifeng Tower in Nanchang, China and the 55-story Greenland Dawangjing Supertall Project in Dawangjing, China.
