056 PROJECT / HANJIE WANDA PLAZA, WUHAN, CHINA SPHERES OF INFLUENCE
ag Licht, LightLife and BIAD Zheng JianWei Lighting Studio collaborated with UNStudio to create a stunning façade of over 40,000 stainless steel spheres.
The plaza features a unique façade that is furnished with over 40,000 hand-crafted spheres made of stainless steel, positioned in relation to each other. ag Licht was brought on board by UNStudio to deliver the digital content. ag Licht, in turn, turned to Cologne-based LightLife to work on the control concept whilst Local Design Institute (LDI) BIAD Zheng JianWei Lighting Studio was responsible for the overall lighting design of the façade. The façade lighting is an integral part of the architectural identity of the building. The light effects from the spheres are designed to enhance the volume both day and night with ten different types of spheres creating dynamic patterns. The spheres are grouped in wave petterns, each with a different distance to the back wall, supporting the shimmering effects and creating a dynamic effect, even with static colours.
The lighting system is fully integrated into the spheres creating a medial light curtain with two layers. The backlit alabaster inlay creates a sharp direct pixel and LEDs on the backside of the spheres project a soft pixel on the back wall. The
two layers can be controlled separately and create astonishing effects depending on the viewing angle. In combination with the reflections of the surrounding light, the two layers create a lively 3D medial platform, named ‘DEEP’. Enabled by an e:cue control system, the façade gives the impression that the spheres are cascading like water or folding like a silk scarf in the wind. Specially designed to easily output video content on LED media installations, 65 pieces of e:cue Video Micro Converter were selected to control and project nearly 80,000 pixels of media content over the massive façade measuring more than 29,000m.
In addition, the Patchelor tool in the e:cue Lighting Application Suite allows the content designer to use a background picture for easy pixel mapping. The versatile software simplifies patching large matrix and fixture setup. The intelligent e:cue control system is able to integrate with a third party video server, making real-time video processing possible and enabling dual-layer video alignment and calibration of colour reproduction.

and the interior pattern language that guides customers from the central atria to the upper levels and throughout the build- ing via linking corridors.
For both the large scale façade and the vast interior spaces, daylight and artificial lighting cast light and shadow depending on the moment of the day and, in a playful manner, material reflections are integrated as one of the layers of the interior finishes. In this way several different zones of lighting effects guide the visitor from the animated kaleidoscopic façade, through the
main entrances with the custom designed chandeliers towards the two central void spaces combining daylight and effect lighting at the vertical funnel structure. In areas where the product is displayed in the foreground, the lighting effects are subdued and centre stage is given to the brands. The interior concept is developed around the North and South atria, creating two different, yet integrated atmospheres. The atria become the centre of the dynamic duality of the two Hanjie Wanda Square identities: Contemporary and Traditional.
Variations in geometry, materials and de- tails define these differing characters. With two main entrances, the North atrium is recognised as a main venue hall, and the South atrium as a more intimate venue hall. The North atrium is characterised by warm golden and bronze materials reflecting a cultural, traditional identity.
In the South atrium, silver and grey nuances with reflective textures indicates the city identity and its urban rhythm. Both atria are crowned by skylights with a funnel structure that connects the roof and the
