The stadium built in the tourist resort on the South China Sea, as well as being a sports facility of excellence, interprets the atmosphere of the place and offers spectators and visitors a wide view of the city and the ocean.
Wuyuanhe Stadium is the first major sports venue on the Chinese tropical island of Hainan. Situated in the provincial capital of Haikou it is conceived to host national and international sports competitions as well as cultural events. The arena is regarded as the first milestone in the implementation of an overall master plan for a comprehensive cultural and sports district, located east of the cityâ€™s new administrative headquarters.
The regionâ€™s characteristically tropical landscape and the special demands resulting from Haikouâ€™s urban structure required an unusual approach to the stadium design. The architects harmoniously integrated the large building volume into a newly created natural and cultural landscape that extends as far as the ocean on its northeast side. Four streamlined ramps built along the buildingâ€™s diagonal axes draw spectators into the stadium interior in a continuation of the flowing structures of the natural environment.
The height of the building diminishes from west to east. Its asymmetry is a response to the specific local conditions and is intended to maximize the number of valuable seats in the western grandstand facing the ocean. In addition to the impressive view, the shape of the arena permits natural shading and ventilation.
The approximately 41,000 seats are distributed over two tiers on the west side and one tier on the east side.
The western section contains facilities for athletes and media while the eastern section accommodates commercial and VIP areas. A 400 meter long track encircles the playing field in the stadiumâ€™s center. From a 2 meter wide, ring-shaped viewing platform at the upper end of the grandstands, visitors can walk around the stadium as though on a panorama trail and enjoy views of the city and ocean. Two prominent, 60 meter high floodlight poles on the east side provide additional lighting for events.
The buildingâ€™s supporting structure must withstand extreme weather conditions and heavy rains. In collaboration with engineers partner, architects developed a special roof construction. The western grandstand is spanned by a crescent-shaped membrane roof that is 270 meters long and 65 meters deep with a surface area of about 10,000 square meters. The membraneâ€™s translucent material allows daylight to penetrate the interior. The roof is constructed of two external compression rings and one internal tension ring.
Wuyuanhe Stadium meets the conditions of the 2-star standard for green building in China. Its sustainability concept includes, among other things, a rainwater utilization system that diverts the water into an underground basin at a capacity of 700 liters per second. Based on a construction method typical of Hainanâ€™s tropical climate, a breathable faĂ§ade made of silver-white, anodized aluminum louvers provides spectators with shade/partial shade and comfortable temperatures even when exposed to bright sunlight and wet weather.
