Beijing National Aquatics Center (Beijing National Aquatics Center)
The National Aquatics Centre, and colloquially known as the Water Cube and the Ice Cube , is an aquatics center at the Olympic Green in Beijing, China.
The facility was originally constructed to host the aquatics competitions at the 2008 Summer Olympics and Paralympics. During the Olympics — where it hosted diving, swimming and synchronized swimming events — 25 world records were broken in swimming. In July 2010, a renovation of the facility was completed, which included the addition of a 12000 sqm public water park.
With Beijing being awarded the 2022 Winter Olympics, the Water Cube became known as the Ice Cube as part of the Water Cube was renovated in 2019 to allow the hosting of curling events.
In July 2003 the Water Cube design was chosen from 10 proposals in an international architectural competition for the aquatic center project. The Water Cube was specially designed and built by a consortium made up of PTW Architects (an Australian architecture firm), Arup international engineering group, CSCEC (China State Construction Engineering Corporation), and CCDI (China Construction Design International) of Shanghai. The Water Cube's design was initiated by a team effort: the Chinese partners felt a square was more symbolic to Chinese culture and its relationship to the Bird's Nest stadium while the Sydney-based partners came up with the idea of covering the 'cube' with bubbles, symbolizing water. Contextually, the Cube symbolizes Earth, while the circle (represented by the elliptic stadium) represents heaven, a common motif in ancient Chinese art.
Comprising a steel space frame, it is the largest ETFE-clad structure in the world with over 100,000 m² of ETFE pillows that are only 0.2 mm (1/125 of an inch) in total thickness. The ETFE cladding, supplied and installed by the firm Vector Foiltec, allows more light and heat penetration than traditional glass, resulting in a 30% decrease in energy costs. This choice was made in view of Beijing's goal of presenting a fully "green" Olympic Games, with zero net growth in total carbon emissions. Likewise, the venue was also designed to "capture and recycle 80% of the water falling on the roof or lost from the pools."
The outer wall is based on the Weaire–Phelan structure, a structure devised from the natural pattern of bubbles in soap lather. In the true Weaire–Phelan structure the edge of each cell is curved in order to maintain 109.5 degree angles at each vertex (satisfying Plateau's rules), but of course as a structural support system each beam was required to be straight so as to better resist axial compression. The complex Weaire–Phelan pattern was developed by slicing through bubbles in soap foam, resulting in more irregular, organic patterns than foam bubble structures proposed earlier by the scientist Kelvin. Using the Weaire–Phelan geometry, the Water Cube's exterior cladding is made of 4,000 ETFE bubbles, some as large as 9.14 m across, with seven different sizes for the roof and 15 for the walls.
The structure had a capacity of 17,000 during the games. It also has a total land surface of 65,000 square meters and covers a total of 32000 m2. Although called the Water Cube, the aquatic center is really a rectangular box (cuboid) 178 m square and 31 m high. The building's popularity has spawned many copycat structures throughout China. For example, there is one-to-one copy of the facade near the ferry terminal in Macau – the Casino Oceanus by Paul Steelman.

Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dynasties. Chinese writing, Chinese classic literature, and the Hundred Schools of Thought emerged during this period and influenced China and its neighbors for centuries to come. In the third century BCE, Qin's wars of unification created the first Chinese empire, the short-lived Qin dynasty. The Qin was followed by the more stable Han dynasty (206 BCE–220 CE), which established a model for nearly two millennia in which the Chinese empire was one of the world's foremost economic powers. The empire expanded, fractured, and reunified; was conquered and reestablished; absorbed foreign religions and ideas; and made world-leading scientific advances, such as the Four Great Inventions: gunpowder, paper, the compass, and printing. After centuries of disunity following the fall of the Han, the Sui (581–618) and Tang (618–907) dynasties reunified the empire. The multi-ethnic Tang welcomed foreign trade and culture that came over the Silk Road and adapted Buddhism to Chinese needs. The early modern Song dynasty (960–1279) became increasingly urban and commercial. The civilian scholar-officials or literati used the examination system and the doctrines of Neo-Confucianism to replace the military aristocrats of earlier dynasties. The Mongol invasion established the Yuan dynasty in 1279, but the Ming dynasty (1368–1644) re-established Han Chinese control. The Manchu-led Qing dynasty nearly doubled the empire's territory and established a multi-ethnic state that was the basis of the modern Chinese nation, but suffered heavy losses to foreign imperialism in the 19th century.
