Dragonair & CNAC(Group) Building

Chek Lap Kok, Hong Kong

Located in the eastern headland of the Hong Kong International Airport Island, the design endeavors to create a simple landmark with a form that is both original and distinguishable. The two 5-storey administration blocks, housing the headquarters of Dragonair and CNAC respectively, are connected by a common lobby with an 18-meter high atrium space. A separate crew-training block, which comprises in-flight simulators, a service mock-up center and a training center, shared by the two airlines, is located next to the main building. Unique to Hong Kong at the time of construction, a ventilated cavity wall system was introduced. This cavity wall is a triple-glazed curtain wall system that consists of an 800mm air cavity between the outer monolithic reflective glass and the inner insulating glass layers. The envelope of trapped air ventilates the façade and optimizes the performance of sound and thermal insulation. This light and modern structure celebrates state-of-the-art technology and creates an eco-friendly architectural landmark for the two companies.
