Architectural Design of Guangzhou International Finance Center

Firstly, the project is the first application of the innovative steel-tube-concrete giant diagonal intersection

grid-cylinder-in-cylinder structural system in ultra-high-rise buildings, which has sufficient lateral stiffness and excellent seismic performance, and is able to effectively withstand strong winds and earthquakes.

The second is that the project is the world's tallest building with a fully hidden-frame glass curtain wall system, and the main tower's 85,000 square meters of glass curtain wall area is also the tallest in a single super-high-rise building at present.

Thirdly, the construction unit has independently developed an overall mold lifting system with international leading level, and the application of this system has created a new speed in the world of two days and one floor for the construction of the main structure.

Fourth, the construction unit independently developed C100 ultra-high-performance vibration-free self-compacting concrete, which was successfully pumped to a height of 411 meters at one time, creating a new height of ultra-high pumping of similar concrete in the world.

Fifthly, the project is the world's first ultra-high-rise building where systematic structural health monitoring has been carried out since the construction stage.

Guangzhou International Center has gathered the latest technology of contemporary engineering structure and construction in the world, through the cooperation of Yuexiu Real Estate Group and the construction general contractor China State Construction Corporation--Guangzhou Municipal Construction Group Consortium, and with the cooperation of many world-class design and consultant units by industry experts, the project has overcome a number of world-class design and consultant units. Under the cooperation of many world-class design and consultant units by industry experts, the project has overcome many world-class construction problems, realized a number of new technological breakthroughs, and created five world firsts. The design of the Guangzhou International Finance Center, which uses a giant diagonal mesh column tube-in-cylinder structure, was selected from among 12 proposals solicited in an international invitational competition organized by the Guangzhou Municipal Bureau of Urban Planning in 2004, with the design concept of "Transparent Crystal", and the goal of which is to make it an elegant building with a beautiful shape and volume, so as to give full play to its role in outlining the sky contour of the city. The goal is to make it a beautifully shaped and elegant building that will play an important role in outlining the city's aerial contours.

The main tower of Guangzhou International Finance Center (GFICC) is a circular triangle composed of six arcs, with a unique curved shape and transparent smooth fa?ade as the main idea of the design, and through the gradual change of width to form a small at both ends and a large in the middle, revealing the building's beautiful and unique spindle shape. The structure of the building is supported by a unique and innovative giant diagonal grid, which presents a clearly visible flowing geometric pattern and creates a strong visual contrast with the segmentation of the floor slabs and the curtain wall system. The "diamond shaped diagonal grid" structure is progressively downsized with the height of the tower. This extended design will allow visitors on the ground to feel the visual impact of the building "going up into the sky".

The outer shell of the building is a giant diagonal mesh outer tube of steel-tube concrete, while the inner body is a reinforced concrete inner tube, connected to the inner and outer tubes by a steel-combined floor cover. This unique and innovative tube-in-tube structural system is a rare one in the world's super high-rise buildings. The entire building facade is beautifully smooth, elegant and modern, extremely crystal clear and colorful, comprehensively separating and surpassing the traditional high-rise buildings in the past. In terms of technology and environmental protection, Guangzhou International Finance Center focuses on the world's advanced construction and management technology, and has made innovative and optimized designs in various aspects such as architecture, structure, electricity and water conservation, so as to realize the harmony and unity of the building with the sustainable development of human beings and the natural environment.

The fully enclosed 103-story Guangzhou International Finance Center equipment operation system is extremely large, to save energy, its neon clothes bear the brunt. Therefore, its coat are glass curtain wall, the material used is hollow double LOW-E glass. Nano-coated glass can selectively transmit light, the material has a low shading coefficient, can resist 70% of the sun's rays, effectively insulating solar radiation. The glass also has a low heat transfer coefficient, which is 50% lower than that of ordinary glass, thus, compared with ordinary glass facade buildings, this coat can reduce 40% of the heat into the room, reducing operational energy consumption. In addition, semi-tempered laminated hollow Low-E glass can significantly reduce the rate of self-explosion, laminated to ensure that the glass will not fall off, people do not have to worry about the safety of walking under the Guangzhou International Finance Center.

Inverter technology is widely used in the West Tower's air conditioning, water pumps and air systems. Not only the water pump frequency control, make full use of the pressure of the municipal water supply network, and all the air system frequency variable air volume, air conditioning is also using variable frequency technology to save electricity, and in the fall and winter and other cooler seasons, the building's air system using the whole fresh air to play less air conditioning more ventilation, energy saving effect. At the same time, the cold source part is a multi-variable system composed of chiller, high-frequency pumps and other intelligent equipment and end combination of air conditioners, through the establishment of a dynamic control model, through the predictive control, over-adjustment and other control techniques to solve the problem of centralized cooling maratou.
