About Zhengzhou Greenland Plaza

The Greenland Plaza tower is instantly recognizable for its sophisticated three- to five-story-tall light-gauge painted aluminum screens. Configured at an outward cant that enhances interior daylighting through scientifically calculated reflections, the screens protect the all-glass exterior from solar gain. The rhythmic cant of the screens, combined with their decreasing size as they rise on the building, creates a dynamic movement that gives the building a fine-grained texture.

The entire experience of the tower is suffused with gradations of light. At the tower’s entrance, the circular ground-floor office lobby features floor-to-ceiling windows, offering views of the gardens and the lake beyond. At the 36th floor, the hotel lobby anchors an 18-story atrium; natural light permeates throughout. Above the observation deck, the heliostat – a digitally shaped solar reflector – focuses sunlight into the atrium. Through an intensive series of daylighting studies, the device was specifically designed to maximize the amount of natural light entering the building.
