1998 New Build
Hong Kong’s 5th Tallest Skyscraper The Center is Located in Hong Kong’s Central Business District, standing at 346m high, and offering panoramic views of Victoria Harbour. This 80 storey building and prominent landmark was completed in 1998, and was the first building in Hong Kong to adopt underfloor air conditioning. The building was originally designed at 381m, but by utilising the AET Flexible Space underfloor air conditioning systems the developer was able to reduce the building height by 35m.
Approximately $US 7 million was saved in curtain walling alone as a direct result of reducing the building height, this amounted to approximately 10% of the total construction cost.
Whilst CAM units were not required for the project, 6500 Fantile units were installed over 59 floors of speculative office accommodation. Providing comfort cooling and aiding the developer to achieve class 1 air certification.
The Center was sold in 2017 for a record $40.2b making it the most expensive office building in the world.
