"Green Olympics" is one of the three key themes for the Beijing 2008 Olympic Games and this theme is integral to the planning and staging of this great event. Beijing promises to provide a clean environment for the athletes by 2008.

The Olympic venues showcase China's scientific and technical results in independent renovation from different aspects with innovative design concept, architecture technology, intelligent service facilities and numerous other hi-tech, energy-saving and environment-friendly technologies.

1.Olympic village-China's No. 1 Village in energy-saving and environmental protection

Olympic Village, as a green answer sheet to the world of China¨@s Olympic project builders, integrates and applies hi-tech technologies on green building like renewable energy, grey water reuse, energy-saving building, air-conditioning system purification, ecological view, intelligent housing, nihil obstat facilities to pursue the harmony among humanity, building and environment, and to achieve an international state-of-the-art large-sized ecological architectural complex.

The recycle water source heat pump system of the Olympic Village

In the recycle water source heat pump system of the Olympic Village, the temperature difference and the heat pump unit heat transfer which contains using resurgent water oneself ,are the efficiency are highest ,the stability well trade the heat source ,the system can the effect ratio reach 3.26,may save electrical energy 60%. Using the resurgent water heat transfer, cannot affect the river course water quality, but in the water contains the energy actually.

Solar heating system of Olympic village

Olympic Village set up 6,000 k solar heating system, hot water can meet the requirements for all of the apartment and auxiliary equipment in the Village. Solar heater system can supply heat bath water for athletes during and after the Olympic. This system will provide hot water for 2000 residents after the Olympic Games.

2.National Stadium ("Nest")-Environmental protection highlights Green Olympics.

National Stadium, also named Beijing 2008 Olympics Main Stadium, fully interprets the concept of Green Olympics of Beijing 2008 Olympics in the aspects of design and technology, showcasing Five Environmental Protection Highlights consisting of advanced environmental protection and energy-saving design, scientific water supply, ventilation and heat preservation systems, reasonable and environment-friendly application of water resource, application of clean energy, and application of environment-friendly building materials and optimization of wastes.

Beijing Olympics Main Stadium -"Nest"

The source heat pump system of National Stadium

The source heat pump system is the use "the underground shallow surface layer soil temperature basic is constant"this characteristic, the underground free energy will withdraw after the heat inter changer and the few electrical energies, thus the realization low temperature potential energy to the high temperature potential energy shift, will achieve both may heat the function which and might refrigerate. This system uses in the stadium under the soccer field region nearly 7,000 square meters sod soil resources, has designed the source heat pump, general equipment department machine capacity 1500KW(always cold load),1800KW(always hot load).

3.The National Aquatics Center(Water Cube) - collection of numerous environmental protection and energy - saving means

Water Cube, as a hi-tech building model with the all-around and systematic installation of energy-saving and environmental-protection system in China, gathers many energy-saving and environmental-protection means achievable with modern science and technology, including ETFE film's function of self-cleaning and water collection, natural lighting, ventilation and solar energy power generation etc.

The natural lighting of "water cube"

In the National Aquatics Center, the membrane structure of roof and building envelope easily achieve the natural light penetration into the indoors spaces; The design focuses on introduction of sunlight to indoors spaces and enhancement the environmental connection between interior and exterior as well as reduction of energy consumption.

4.National Indoor Stadium - inspiration from Chinese folding fans

Environmental protection design is applied for the engineering and construction of National Indoor Stadium, covering energy-saving design, natural lighting, solar energy application, heat energy from shallow seated groundwater and new building materials etc.

The solar energy power system of National Stadium

The national stadium is used of the solar grid connection generation system of the 100KW capacity which the technique has reached the advanced international command and makes the model project of the national technology. The power generation system provides the light for the underground garage and the square light. The solar battery is equipped on the roof and the screen put on the southern wall.

5.Olympic Green - Green Lung of Beijing

By means of lake excavation for heaping a hill, wetland protection, greening, biodiversity recovery and "ecological corridor" project, a 760- hectare regional ecologic system in Olympic Green is completed, installing a "green lung" for Beijing. The Park realizes energy-saving and environmental protection through the application of ground source heat pump/air source pump system, sewage disposal system, Freon-free environmental-friendly cold media air-conditioning system, solar energy environmental protection system, rainwater recovery system and renewable materials.

The Olympic Green

The application of renewable materials in Olympic Green

Renewable product is an admixture of rejected wood, bran and plastic and has characters of corrosion protection and resistance. As substitute for wood, the product is used as wall, floor, flat, frame, the cover of concrete bridge, plank road and handrail and so on in Olympic Green. The engineering of wooden and plastic materials covers 48,544m2 and saves wooden resources.
