Beijing Olympic Village, a green project

Updated: 2008-03-05

(BEIJING, March 5) -- In order to carry out the concept of a "Green Olympics," the engineering staff has applied a series of new technologies and materials to make the Olympic Village a truly green project, according to Guoao Investment Company, the contractor.

Through the heat exchange system, the Village is projected to draw 7.89 million kilowatt hours of renewable energy from the sun and recycled water during the 2008 Olympic Games. After the Games, the system will continue to accumulate 6.7 kilowatt hours per year, said company representative Liu Rong at a press conference in Beijing on Wednesday.

The system taps energy from Qinghe sewage treatment plant and upgrades it through heat pump devices for winter heating and summer cooling purposes. The technology can save energy by over 40 percent compared with ordinary air-conditioning systems. Due to cooling devices set up outside the Village, there will be no noise or smoke emissions inside. Even during the summer, the thermal conductance effect, evident in most large building clusters, can be totally eliminated, a sign of the international level of the renewable energy that can be attained from urban sewage treatment.

In the Village, solar energy collecting tubes have been installed on rooftop gardens with an area of 6,000 square meters. The system can meet bath water demands of 16,000 users during the Games and some 2, 000 households after the Games. The project can save electricity by 5 million kilowatt hours a year.

Over 20 highly advanced technologies have been utilized to build low energy consuming buildings in the Village. They include solar heating, solar hot water, solar thermoelectric cogeneration, and intelligent control. With a capacity of saving 36 kilowatt hours per square meter a year, the buildings consume just one-thirtieth of the energy consumed by conventional buildings, saving a total of 147,000 kilowatt hours annually.

The waste water in the Village will be treated through a water ecological system featuring the animal and plant food chain. The 200 tons of water recycled daily can be used for landscape watering in the Village.

A great volume of environmental protection materials, including paint, has been applied in the construction process. In addition, accessible facilities and drinkable tap water systems will be available in the Village.
