Located in Hong Kong, Tung Chung Swimming Pool was designed by Ronald Lu & Partners. Reflecting its coastal locality and function of an aquatic sports venue, the design takes the concept of a sea shell resting on the shore and shaped in an organic and aerodynamic profile using a double-layer PTFE tensioned membrane over a light-weight long-span steel truss system. This tensile membrane performs as a sustainable building envelope allowing daylight to infiltrate through it so that, in all seasons, users staying indoor can bathe in diffused and glare-free natural light.
With the membrane’s high-albedo nature and low thermal transmission value due to a layer of insulating air trapped between the double-layer membrane, this cool roof contributes to the indoor thermal comfort which is crucial to a naturally ventilated building in a sub-tropical climate. This flexible roof also helps to attenuate noise in the indoor pool which is essential to users’ comfort and life guards’ awareness of drowning call.
