Clad in a geometric diagrid shading fin system, the Jiangxi Nanchang Greenland Zifeng Tower has a striking presence on the Nanchang skyline. Setting a high standard for further development in Nanchang, the tower balances high-performance design, efficient program, and an impactful aesthetic.
At ground level, the site is landscaped to create a cohesive design that extends from the ground plane to the roof of the retail podium. With a central core, the tower’s floor plates are highly flexible. Office floors occupy the bottom two-thirds of the building, while the top third houses a luxury hotel. The change in program is registered by the “Great Window”—an aperture carved into the tower’s mass. Formally, the Great Window transitions the floor plates to a suitable size for the hotel program while distinguishing the tower on the skyline.
Perforated, aluminum triangular fins trace up all four elevations of the tower and anchor the building’s high performance features. Shading the tower, the fins prevent excessive solar heat gain and glare to the interior. Illuminated at night, the fins are programmed with white LED lights to serve as the tower’s primary exterior lighting scheme, reducing energy loads typically associated with this design element.
A suite of comprehensive sustainable design elements, including high-performance glass and low-flow fixtures, helped the tower earn LEED© Silver certification.
Enhancing public space and seamlessly integrating a variety of programs, the mixed-use Jiangxi Greenland Zifeng Tower indicates that the future development of China’s burgeoning cities can be both visually striking and environmentally responsible.
