Skidmore, Owings & Merrill LLP (SOM) and CNTC Guangdong Tobacco Corporation today celebrated the topping out of Pearl River Tower in Guangzhou, China 71-story building designed to become one of the most energy-efficient skyscrapers in the world.
“Today we celebrated the innovative structural form of Pearl River Tower as it moves toward completion,” said Richard Tomlinson, managing partner, SOM, who attended the topping out ceremony. “Our team was able to design to the forward-looking, ambitious goals that were set out, and this milestone in the building development process is a great achievement for CNTC Guangdong Tobacco Corporation, most importantly, this project can only be successful with the support of the land owner, property developers, interior designers, contractors and the local architect and engineer.”
The 2.3-million square-foot tower incorporates sustainable technology and engineering . Due to the unique shape of the building, as well as the wind and seismic loads imposed on the tower, the design integrates structural systems, in which both steel and reinforced concrete are utilized. Among the structural features, we notice the integrated wind turbines. These turbines, which are fed from funnel-like openings in the façade. They are supported on floor slabs within the opening zones and are laterally braced against the floor above.
A series of other sustainable design and engineering elements, including solar panels, double skin curtain wall, chilled ceiling system, under floor ventilation air, and daylight harvesting, contribute to the building’s energy efficiency.
Pearl River Tower is scheduled for completion later this year.
