Guangzhou new landmark
Guangzhou, the international city that has been reborn through the Asian Games, has ushered in its new landmark: the tallest building in South China, the 432-meter-high Guangzhou International Financial Center (commonly known as “West Towerâ€).
Guangzhou International Finance Center (West Tower)
The 103-story "transparent crystal" will be equipped with ultra-platinum office buildings, super five-star hotels, business banquet centers, international conference centers and high-end shopping malls. At the highest level of the restaurant, overlooking Guangzhou, its crystal-clear crystal architecture adds another highlight to Guangzhou's night scenes and will be among the top 10 super high-rise buildings in the world.
Five world leaders
Guangzhou International Finance Center (Xita) has created five world firsts in architectural history.
Created a new world level of super-high pumping of similar concrete.
Created a new world speed of 2 days/layer of main structure construction.
The world's tallest building with a full hidden frame glass curtain wall system.
The world's first super high-rise building for systematic structural health monitoring from the construction stage.
For the first time in super high-rise buildings, an innovative CFST giant oblique gridd cylinder structure system was applied.
Leading leading lighting technology
Guangzhou International Financial Center (Xita)'s leading position in architecture has created a leading position in lighting technology. West Tower maximizes the theme of comfort, energy saving and environmental protection. The lighting design concept of West Tower has reached international standards. The program adopts a more professional and intelligent DALI digital lighting control system, reflecting the 21st century integrated and intelligent office. The development trend.
Lighting control design requirements
The design institute refers to several important parameters of building energy efficiency, and takes into account the requirements of the owner for large-scale control of lighting equipment, and clarifies the four requirements that the lighting system should meet:
Energy saving
According to professional statistics, the lighting power of smart buildings accounts for about 20% of the total electricity used in buildings. In fact, in most cases, many areas do not need to open or turn the lights to the brightest. Excessive lighting not only causes light pollution but also wastes energy. In today's energy-constrained and state-promoting energy-saving situation, efficient lamps, energy-efficient light sources (T5 fluorescent lamps), efficient electrical appliances (digital dimming ballasts (EEI=A1)) and efficient lighting control systems are used. The program is currently the best choice in the international and domestic markets.
flexible
Since the various floors of the West Tower are fully open structures, such as tenants or owners need to change the function of the work area or cut off the partition, the system can be conveniently set up with a purely digital system, without rewiring, just set by software. , group control, to achieve the purpose of partition.
Efficient management
The entire West Tower has 60 floors of office buildings, with a large number of lighting fixtures, a large number of circuits, and large capacity. How to improve the stability and reliability of operation, make control and operation more simple, convenient and flexible, and make management more automated and efficient, reducing a large number of Simple and repetitive labor is the focus of lighting system design considerations. According to the lighting control requirements of different regions, the system should have a variety of control methods.
Humanize
The intelligent lighting management system not only can realize basic lighting control, but also can improve the quality of the lighting environment through scenes, dimming, automatic control, etc., so that employees can work happily and efficiently in a comfortable and warm, high-quality light environment. .
The owner's requirements for the design principles, technical requirements, control areas and control modes of the intelligent lighting control scheme are fully studied, and how the lighting and its control system further conveys the design concepts and control methods expressed in each office area. Comprehensive considerations of many factors such as environmental characteristics, characteristics of lamps and light sources, power distribution requirements, difficulty in construction, and requirements for operation and maintenance. After careful analysis, we recommend the use of Austrian Tridonic (TRIDONIC) DALI digital intelligent lighting control technology and system.
The main advantage
Protect your eyes and improve lighting quality
Fluorescent flashing with fluorescent lamps with traditional ballasts can easily cause the staff to swell, fatigue and reduce work efficiency. The digital dimming technology enables the dimming electronic ballast to operate at a very high frequency (40KHz-70KHz), which not only overcomes the flash frequency, but also eliminates the instability of the brightness caused by the use of the starter. Employees provide a healthier and more comfortable environment that is more important than the exquisite room decoration and upscale office equipment. The digital dimmer can adjust the illumination of each area according to the quality standard requirements of each area to ensure the illumination quality of each area. The creation of a very human working environment has greatly improved the efficiency of work, which can bring unexpected economic returns to the owners.
Energy saving and environmental protection, reducing carbon emissions
Make full use of natural lighting, automatically adjust the brightness of the light according to the ambient illumination, without manual intervention, thus maintaining a constant illumination output. This allows the combination of natural light and light brightness to provide suitable office lighting, which can greatly save energy consumption. And through the button panel to adjust the brightness of the lighting in the office area, until the office needs, can make the lamps do not need 100% illumination, saving energy.
More importantly, the energy rating of the DALI digital ballast is the highest level of world ballast A1. It has the highest efficiency and lowest energy consumption. For smart buildings with a large number of fluorescent lamp ballasts, the energy savings are considerable.
Flexible and convenient to meet future rental needs
The biggest feature of DALI technology is that the single luminaire has an independent address. The DALI system software can accurately dim and switch the single lamp or any lamp group, whether these lamps are the same circuit or different circuits in strong power, and Lighting control is independent of the strong electrical circuit. The DALI system software provides independent addressing of single or multiple luminaires on the same high-voltage loop or on different loops for individual control and arbitrary grouping. This concept brings great flexibility to the lighting control, users can design the lighting solution to meet their needs as needed, and even modify the control requirements during the operation after the installation, without having to do any work on the line. change. Due to the simple structure of the system, there is no need to illuminate the control box or dimming box, and the traditional wiring method can be retained. Therefore, if the tenant or the owner needs to change the function of the working area or cut off the cutting, there is no need to re-route, just set by software. Group control is used to achieve the purpose of partitioning.
