Completed after five years of design and construction, the Taiyuan COOC International Center is currently 色控传媒鈥檚 tallest built twin towers in China. With a total building area of 270,000 square meters, the 230-meter twin tower integrates office, commercial, dining and other functions. Symmetrically arranged along the central axis, the 53-floor twin towers were designed to look like a multi-faceted crystal.
It is strategically located at the geometric center of the city. Found west of the region鈥檚 鈥渕other river,鈥 the Fen River, and south of the city鈥檚 development axis on Yingze Street, the towers are both 鈥渟eeing鈥 and 鈥渟een鈥 in this location and are the most important part of this super high-rise complex.
The design draws inspiration from the city of Taiyuan, which is known as the 鈥淒ragon City鈥. Through several sets of vertically developing curves, the design creates the momentum of 鈥淪oaring Twin Dragons鈥 and visualizes the light and shadows of rippling water. 色控传媒 used an abstract method to relate to the city鈥檚 cultural heritage and give the massive buildings a sense of lightness and upward movement.
Its multi-faceted crystal image is formed by applying different cutting paths on the four corners of the tower, making the towers visually slenderer. More importantly, this also solves the spatial pressure brought by the towers鈥 high floor area ratio (FAR), and improve the towers鈥 aspect ratio, which sink straight into the ground.
In addition to applying different cutting paths, the towers鈥 symmetrical arrangement along the axis enhances the effects of light and shadow and gives the building multiple 鈥渕icro-expressions鈥 when viewed from various angles.
The fine horizontal lines of the curtain wall fa莽ade vary subtly in their scale of projections. The differences are enhanced by reflections and shadows, forming a vertical image of continuous curve fluctuations. With the unit curtain wall construction method, the horizontal overhanging components are consistent with the glass curtain wall and connected by grab points, which are suitable for high-precision installation. A 100-millimeter gap is left between them to reduce dust accumulation on the continuous glass surface.
The podium echoes the tower with the use of folded glass, while the lobby uses a more transparent two-story glass grab-point curtain wall. This, along with the folded glass fa莽ade, strengthens the visual impact of the semi-open space, which measures about 1000 square meters: 15 meters high, 25 meters wide and 40 meters long. This approach improves the relatively cramped ground and connects the inner and outer blocks. Further, the main entrance of the two lobbies are set to face the public space, creating a flexible indoor-outdoor space and strengthening the openness of the buildings.
Meanwhile, the twin towers鈥 location and height provide occupants with an astounding view of the city, with the Fen Park in the foreground, and the Taihang and Lvliang mountains in the background. A chamfered corner design strategy was also applied in the floorplan, opening the corner space and optimizing the view of the Fen River and the rest of the city.
The new twin towers standing on the banks of the Fen River are set to become a new symbol of the city and its continuous evolution.
