Zhengzhou Greenland Plaza by SOM

Crowning the skyline of the emerging city of Zhenghou, the tower’s circular form, Zhengzhou Greenland Plaza by Skidmore Owings & Merrill LLP (SOM) has opened its doors to its office users. The circular 60-story tower takes its place as the tallest building in the central Chinese city.

Located in the northeast portion of Zhengzhou, the 919-feet (280-meter) tall tower is a response to the surrounding development’s shape that centers on a manmade lake. Zhengzhou Greenland Plaza punctuates the neighborhood and provides the area—and the city—with an iconic new landmark on the skyline.

The tallest building in the central Chinese city, Zhengzhou Greenland Plaza houses a mixed-use program of offices on its lower floors and a 453-room hotel above.

Sophisticated aluminum screens are configured at an outward cant that enhances interior daylighting through scientifically calculated reflections, while protecting the all-glass exterior from solar gain. The same outward cant allows for a nuanced approach to artificial lighting, providing for dramatic nighttime lighting of the building which makes the tower a beacon.

Conceived as a classical column, the tower includes a heliostat that crowns the building and reflects daylight throughout the hotel atrium. Computer-controlled dimmer switches modulate the light level based on the illumination provided by the reflector, enabling the atrium to consume less energy and generate less heat throughout the year.
