CWTC Tower B is a new hub for commerce and tourism in Beijing's Central Business District. The 300-meter-tall building is the latest addition to the CWTC, a growing mixed-use campus and home to some of China's leading companies. The exterior is clad in a sleek curtain wall of glass with self-shading vertical fins and a canted façade. To reduce energy use, the exterior glass curtain wall is tilted to decrease glare and solar heat in the warm summer months.
While the top of the building is illuminated by 88 sets of Philips Color Kinetics ColorReach LED floodlights, the architecture of the tower walls is accentuated with a total of 400,000 white LED light points.
More precisely, Philips Color Kinetics eW Flex Micro string lights are embedded into cavities on the curtain wall, rendering them “invisible.”
From the outset, Signify’s Professional Lighting Services team worked closely with the architect and reserved the cavity structures for the lighting. The installation nodes are designed so the illumination angles and installation positions fit perfectly the structure of the curtain wall, preventing light from shining inside the offices at night.
Assisting with the installation was the Beijing Fortune Lighting System Engineering Co. Ltd, which is a member of the Signify Value Added Partner program.
The lights are digitally controlled by a Philips Color Kinetics Video System Manager Controller, enabling video content to be streamed and scaled across the building’s entire façade via the control of thousands of LED lights. These LED motion graphics convert the tower into a giant canvas or video screen.
