China has been known to have a polluted air for many years now. However, their courage of building an eco-friendly Olympic village will definitely change the image of China as the main contributor to our green house gases. They have used various eco friendly materials and processes to run the Olympic village. One sample of it is the hot water used by the athletes are all solar powered. Buildings are also using earth friendly materials like ethylene tetrafluoroethylene or the ETFE, and some green tech such as the solar heating, solar hot water, and the solar thermoelectric cogeneration. I am sure, through this sep made by China, there will be a big chance for them to be the most eco friendly country.
1. Beijing National Stadium – Bird’s Nest
Home of both the Opening and Closing Ceremonies, this stadium will also feature the track and field and soccer events. With roughly 11,000 in temporary seating arrangements for the Olympics, it will have 80,000 permanent seats. Dubbed the Bird’s Nest, the structure takes on the appearance of a nest as interwoven structural elements of the facade camouflage the structure underneath. Beijing National Stadium was designed by a consortium of Herzog & de Meuron Architekten AG, Arup Sports, and China Architectural Design and Research Group. The Bird’s Nest is supposed to gather roughly 70% of the water needed to run the facility.
2. Beijing National Aquatics Center
Also known as Water Cube, the National Aquatics Center was designed to resemble a cube of water, or bubbles. The bubbles are made of a transparent plastic called ethylene tetrafluoroethylene (or ETFE) which is filled with air and attached to a steel frame surrounding the edge of the bubble. The Water Cube is expected to be 30% more energy efficient than a standard building of similar size. The building takes on different colors from LED lights, which are super efficient. Water Cube was designed by Arup, PTW, and China State Construction and Engineering Corporations.
3. Beijing National Indoor Stadium
The National Indoor Stadium has photovoltaic generators installed under the roof and behind the curtain walls of the structure putting out as much as 100 kilowatts of electricity daily. Attached to the walls and roof of the stadium, the PV system has over 1,100 solar battery components. The $125 million stadium seats ~19,000 and was designed by Glöckner3 Architecture und Städtebau with Beijing Institute of Architectural Design to resemble an open Chinese fan.
4. Beijing Olympic Green Convention Centre
This convention center was designed by RMJM to filter roughly 20,000 accredited journalists throughout the Olympics. RMJM’s design includes systems that make use of natural elements along with very efficient insulation throughout the building. Additional green features include rain water collection on the roof for flushing systems and irrigation of the surrounding landscape, an ice storage cooling system, and a “free air cooling” ventilation system in the public foyers of the convention center.
5. Beijing Olympic Village
Expected to house over 16,000 athletes and officials during the Olympic Games, Beijing Olympic Village has a list of green elements, most of which relate to both energy and water efficiency. With green tech such as solar heating, solar hot water, solar thermoelectric cogeneration, and intelligent controls, Olympic Village buildings consume about 1/30th of the energy consumed by conventional buildings. Plus, 200 tons of water will be recycled every day and used in landscaping.
6. Beijing Olympic Basketball Gymnasium
With a capacity for 18,000 spectators, the Beijing Olympic Basketball Gymnasium has an LED display system, rainwater recycling system, easy to clean glass and other technologies, and solar panels that provide some of the building’s energy. Designed by Beijing Architecture Research Institute, the structure is wrapped in an aluminum-alloy cladding, which looks surprising similar to bamboo or some kind of natural wood. At night, colorful LEDs bounce off the cladding and light up the structure.
7. Olympic Green Tennis Center
Designed for natural ventilation, you may notice that the shape of this structure resembles a flower, or petals of a flower. The stadium has 12 sections that look like 12 petals of a lotus flower. The Olympic Green Tennis Center features a zero-discharge sewage treatment system where 100% of sewage is treated through membrane biological reactors before being recycled for watering. The structure is further equipped with a geothermal heat pump system through which ground sourced energy is absorbed for cooling and heating.
