(BEIJING, October 5) -- The flower-shaped Olympic Green Tennis Center is meticulously designed for natural ventilation to ensure the quality of the competitions for athletes and spectators.
The center's three main courts are dodecagonal with each of the 12 sides as a stands. The gray cement walls around each of the 12 sections form 12 stands which look like 12 petals of a lotus flower in the Olympic Forest Park.
With 10 competition courts, the venue covers a surface area of 16.68 hectares and has a building area of 26,514 square meters. The venue has a capacity of 17,400 seats, including 10,000 seats in the main court; 4,000 seats in the No. 1 court; 2,000 seats in the No. 2 court; and 1,400 seats in the seven preliminary competition courts at the No. 2 platform. Next year, the Olympic tennis and Paralympic wheelchair tennis competitions will be held at the Center.
The main court is the biggest among the three "lotus flowers." Its "petals" are sustained by 48 sloping beams, each weighing 62 tons with a length of 17 meters. On August 17, 2008, some 10,000 spectators will gather here to watch the final matches of the Olympic tennis events.
Taking into account the small size of the tennis ball and its high speed, the architects have designed a steep stands which gives the spectators the best sight line, according to Zheng Fang, chief architect of China State Construction International Shenzhen Design Consulting Company, Ltd -- the construction management group for the Olympic Green Tennis Center project.
For the same purpose, the height difference between the stand rows is nine cm, instead of six cm for other tennis stands, he added.
