Name two Olympic buildings that are environmentally friendly.

London Velode The circuit's curved façade, clad in wood panelling, is reflected within the city's sleek track. Thanks to the wood paneling, the 6,000-seat venue can be naturally ventilated without relying on air-conditioning equipment. London Velodrome and the skylight design on the roof of the stadium also minimizes the use of artificial light sources.

The unique rainwater harvesting system also reduces the amount of water required to flush toilets and surface irrigation. But the London Organising Committee says the cost of installing the system far outweighs the economic considerations. Basketball Court The Olympic basketball court is not only dazzling, but also embodies the will of democracy.

Having spent less than £30 million and was completed on schedule last year, the arena is the largest temporary venue at the Games. The box-like design allows it to be dismantled and reused in other parts of the world in the future. There are rumors that the arena could even be sold to the organizers of the 2016 Olympic Games in Rio de Janeiro, or, perhaps, in the future, it could be reassembled in a poorer country.

The 12,000-seat venue is designed to be lighter, which means less steel and concrete is used. While past Olympic hosts including Atlanta, Athens and Beijing have all built a lot of money, it has inevitably caused some waste. But London's basketball stadium shows that the construction of Olympic venues can also be sustainable and more environmentally responsible.

Aquatics Center The projecting curved roof is the second largest venue after the main Olympic stadium and is the first thing visitors to the Olympic Park will see. Built on a brown site, the high ceilings of the water centre are suspended over two 50-metre swimming pools and are made of sustainable red Lauro wood. The exterior structure is constructed of prefabricated concrete modules, which not only reduces the emissions required to build the facility, but also eliminates the need for painting.

The indoor grandstand is made of steel and phosphate-free polyvinyl chloride material, which can be used after the event. Most of the building materials, including the 866,000 tiles needed for the pool and changing rooms, were delivered to the stadium by train, not truck.

Bird's Nest, Olympic Park.

Yang Weiguang, deputy director of the Beijing Municipal Science and Technology Commission, couldn't help but proudly add this sentence when introducing the green and environmental protection technology in the Beijing Olympic venues today.

Through the construction of large-scale venues for the Olympic Games, from large-scale public facilities to residential buildings, China has obviously accumulated a large number of green environmental protection concepts and operating technologies, which will play a symbolic role in China's future construction of environmentally friendly cities, especially in Beijing. The Beijing Olympics has undoubtedly erected the banner of "green environmental protection" for China's construction in the future!

The use of green energy technologies such as solar energy, wind energy and geothermal, so that the proportion of green energy provided by the Beijing Olympic venues is as high as more than 26 percent, and the Beijing Olympic venues have become one of the buildings with the largest amount of solar power generation in the world, and the solar power generation system has been applied in seven Olympic venues such as the National Stadium, with an annual power generation capacity of 580,000 kilowatt hours, which is equivalent to the annual electricity consumption of nearly 10,000 people in Beijing, and this alone can reduce carbon dioxide emissions by 570 tons.

Beijing is a water-scarce city, and the conservation and recycling of water has become the top priority in the construction of the Olympic venues. Due to the use of natural rainwater harvesting, sewage treatment and recycling technologies, the average comprehensive utilization rate of rainwater in the Olympic venues has exceeded 80% for many years.

As the "Water Cube" of the National Aquatics Center, it can be automatically replenished to the water body of the venue through the rainwater system, and the reclaimed water treatment system of the venue itself can basically achieve "zero discharge" of sewage for such a large-scale swimming venue.

Green environmental protection is not only reflected in the Olympic competition venues, in the Olympic ** village, all shower equipment is also heated by solar energy. It has been revealed that during the Olympic Games, the Olympic Central Area will also use all high-efficiency and energy-saving electric and hydrogen fuel environmentally friendly vehicles to achieve "zero emissions".

Yang Weiguang stressed that Beijing's atmosphere has gone through more than 10 stages of environmental management, and the formulation of each treatment plan is a technical demonstration first. The experience of formulating and completing more than 10 programs will provide a lot of hardware management and software technical support for Beijing and even the whole country in terms of environmental governance.

With the participation of a large number of Chinese and foreign enterprises in design, architecture, construction, research and other departments, the accumulation of a large number of new technologies and new experience will undoubtedly lay a solid foundation for the promotion of China's future "green environmental protection" concept.

The construction of venues for the Beijing Olympics has come to an end, and a green and environmentally friendly China continues to make great strides forward. As Yang Weiguang said, the green and environmentally friendly technology applied in the construction of Olympic venues will leave a valuable "legacy" for China and the international community.

This Beijing Olympic Games is mainly reflected in the construction of stadiums!

"Green Olympics" is one of the three major themes of the 2008 Beijing Olympic Games

It is necessary to use the sustainable development idea of protecting the environment, protecting resources and protecting ecological balance to guide the engineering construction, market development, procurement, logistics, accommodation, catering and large-scale activities of the Games, so as to reduce the negative impact on the environment and the ecosystem as much as possible;

It is necessary to actively support the strengthening of environmental protection and municipal infrastructure to reduce rivers, improve the ecological environment of the city, and promote the sustainable and coordinated development of the economy, society and environment;

It is necessary to make full use of the extensive influence of the Olympic Movement, carry out publicity and education on environmental protection, promote public participation in environmental protection work, and raise the environmental awareness of the whole people;

After the end of the Olympic Games, it is necessary to create a rich environmental protection legacy for Beijing China and the world's sports VI: the Olympic Green Building Demonstration Project; a new environmental management model for holding large-scale sports games; mechanisms for active public participation in environmental protection; Continuous improvement of Beijing's environment.

In a word: it is to integrate the concept of sustainable development throughout the whole process of preparation, holding and post-competition. To achieve these goals, we need the support and participation of all sectors of society and the general public, care about environmental quality, supervise environmental law enforcement, participate in policy advice, and choose green living.

There is another meaning:

Verbruggen described the preparations for the Beijing Olympics as "green Olympics", he said, "green Olympics" here not only refers to a concept of the Beijing Olympic Games, but also refers to the support given by China and Beijing Municipality to the preparations for the Olympic Games, and the construction of venues, financial guarantees, market development and other work of the Beijing Olympic Games have satisfied the IOC.

Three major themes: Green Olympics, Science and Technology Olympics, and Humanistic Olympics.

Green Olympics --

Environmental protection is the primary condition for the planning and construction of Olympic facilities, and strict ecological and environmental standards and systematic guarantee systems have been formulated.

Widely adopt environmental protection technology and anti-burial means to promote environmental governance on a large scale and in all directions

urban and rural greening and beautification and environmental protection industry development;

Enhance the environmental awareness of the whole society, encourage the public to consciously choose green consumption, actively participate in various activities to improve the ecological environment, greatly improve the environmental quality of the capital, and build a livable city.

Specific examples: five major greening projects"Almost done.

The Olympics are burning new landscapes, dressing up Qingdao (search keywords online).

And then there's the specific case of Beijing:

In 2001, when the Beijing Olympic Games were bidding, the concept of "Green Olympics" was proposed, and the Olympic style led China's environmental protection trend.

In the past few years, the concept of "Green Olympics" has been deeply rooted in the hearts of the people, and environmental protection has become the fashion of contemporary Beijingers.

Environmental protection work has been widely supported by the Beijing Municipal People, "no car day" activities, the extensive use of reclaimed water, and the adoption of various energy conservation and emission reduction measures.

After bidding for the Olympic Games, Beijing has achieved outstanding results in environmental protection work.

Beijing's environmental protection efforts are supported by neighboring provinces and cities.

In order to cooperate with the Olympic Games, the five surrounding provinces and regions signed an agreement with Beiranxujing to jointly protect the environment.

Environmental protection work has been increasingly valued by the state.

In fact, there are many examples, which shows the degree of attention paid by the whole people

1) The energy conversion of the "Bird's Nest" venue is to convert solar energy into electrical energy when the electricity is provided. Electricity

2) The methods to prevent the "bird search nest" from being corroded can be: making the metal into an alloy or plating a layer of inactive metal on the surface of the metal

3) Acid rain can corrode metals Therefore, fill in: acid rain

In cities, the formation of acid rain is related to the exhaust gases emitted by motor vehicles

4) The principle of the cavity and leakage reaction of carbon monoxide and hematite smelting iron, that is, the reaction of iron oxide and carbon monoxide to form iron and carbon dioxide, so fill in: Fe2

O33CO high temperature.
