The Significance of Green Olympics
How to understand the green Olympics
Understanding of the narrow sense of green Olympics: the narrow sense of green Olympics refers to the coordinated development of natural environment, ecological environment and human society in the process of bidding, organizing and hosting the Olympic Games and in a period of time after hosting the Olympic Games directly affected by the Olympic Games. The contents mainly include ecological greening and environmental greening.
Understand the green Olympics in a broad sense: the green Olympics in a broad sense refers to the material and ideological green related to the Olympic Games. The "green" here not only refers to the "green" in the narrow sense of the Green Olympics, but also refers to other ideas and practices that are in harmony with the development of nature and society. The content is very extensive, including material green and consciousness green.
Material green mainly includes the following contents:
1. Venues and transportation: The construction of venues and transportation should be more humane, scientific and economical, and the reuse after the Olympic Games should be fully considered to avoid unnecessary negative impact on economic development and people's lives.
2. Management: Green Olympics requires that its management is also green. Strictly control the composition of management institutions and personnel, and run the Olympic Games well with less resources.
3. Funding: The funding for hosting the Olympic Games should also be green, and the investment in the Olympic Games should not be increased without foundation, which may have a great negative impact on the Olympic Games.
4. Sports nutritional supplements: sports need nutritional supplements, and sports training needs effective recovery and improvement methods, but it cannot exceed the boundaries of prohibited drugs and prohibited methods stipulated by the IOC Drug Administration Committee. This is the green color of sports nutritional supplements.
Conscious green includes the following main contents:
1. Green awareness of Olympic participants: Olympic participants, including organizers, referees, athletes and team members, should have good green awareness. The organizer's green consciousness is reflected in his macro-control and micro-transformation of the Olympic Games. The green consciousness of the referee is reflected in his grasp of the fairness and rationality of the game; The athlete's green consciousness is reflected in his understanding of fair competition and his requirements for higher, faster and stronger; The team member's green consciousness is reflected in his support and encouragement to the Olympic athletes in his own country and the host country of the Olympic Games.
2. Green consciousness of residents in the host city of the Olympic Games: People are the most active factor in productivity, and the people closest to the Olympic Games are one of the most active factors affecting the Olympic Games. Therefore, the green awareness of residents in the host city of the Olympic Games is also extremely important. This kind of green consciousness is reflected in the overall quality of urban residents, their understanding of the Olympic Games, the degree of civilization, their recognition of internationalization and their demand for material and spiritual civilization.
Venues witness the Green Olympics.
The roof of the "Water Cube" collects 100% rainwater, and the "Bird's Nest" absorbs energy from the soil.
More than 65,438+6,000 athletes and officials staying in the Olympic Village can "sunbathe" comfortably every day during the Beijing Olympic Games-there is a 6,000-square-meter solar photothermal system in the Olympic Village. After the Olympic Games, this system will meet the domestic hot water demand of 2,000 households nearby, saving about 6,543,800 kWh of electricity and more than 2,000 tons of coal every year.
The concept of "Green Olympics" runs through the planning, design and construction of Beijing Olympic venues.
"Bird's Nest" has become the representative of energy conservation.
The Bird's Nest, the main stadium of Beijing Olympic Games, is a magnificent and environmentally friendly bird's nest. The Bird's Nest is equipped with a100KW solar photovoltaic power generation system, with an average daily power generation of over 200KWh, which can provide sufficient lighting power for the15000m2 underground garage. The use of advanced membrane structure ensures the brightness inside the venue and saves energy; Rainwater utilization is fully considered in the design. The collected rainwater can be used for lawn irrigation, air conditioning and water cooling, toilet flushing, competition venue greening, fire fighting, etc., saving nearly 60,000 tons of water every year.
What is more striking is that the Bird's Nest uses ground source heat pump to absorb energy from the soil and compensate the air conditioning system of the stadium.
The "Bird's Nest" was "slimmed down" in the construction process, which saved a lot of resources and better explained the concept of "Green Olympics". After optimizing the original design, the Bird's Nest cancelled the openable roof and expanded the opening of the roof, and the number of seats was reduced from 65,438+10,000 to 965,438+10,000. This makes the "Bird's Nest" reduce the steel consumption by 6.5438+0.2 million tons and the membrane structure by 9,000 square meters.
"Green" is the common pursuit of * * *
The concept of "Green Olympics" is the common pursuit of Beijing Olympic venues. The 30,000m2 roof of the National Swimming Center "Water Cube" can collect 100% rainwater, and the rainwater collected by the rainwater collection system is equivalent to the water consumption of 100 households in one year. Membrane structure and other related technologies make full use of natural light energy. Now the average daily use of natural light is 9.9 hours, and the power saving effect is remarkable.
In the residential area of the Olympic Village, 42 buildings have adopted the green air conditioning system, that is, the reclaimed water source heat pump system, which extracts the temperature in the secondary effluent (reclaimed water) of the sewage treatment plant, provides heating in winter and cooling in summer for the Olympic Village, saves thousands of tons of coal every year and reduces the emission of greenhouse gases such as carbon dioxide.
In the Olympic shooting range, a temperature sensing device was installed between the double curtain walls. With this system, the shooting range can adjust the indoor temperature with the seasons and reduce the energy consumption of air conditioning, refrigeration and heating.
In the Olympic Forest Park, the intelligent irrigation system can feed back various environmental information such as soil and plants to the central computer, saving half of the water consumption compared with manual or semi-automatic irrigation.
In Qingdao Olympic Sailing Center, the seawater source heat pump air conditioning system uses seawater with relatively stable temperature as cold and heat source to provide energy for cooling and heating for the media center. ...
Technology will benefit the public.
According to statistics, there are 358 "Green Olympics" projects in Beijing Olympic Games, including 69 new energy projects, 68 building energy-saving projects 168, and 0 water resources projects 1. Nine solar hot water systems were built in the Olympic Games.
So the deputy director of the Environmental Engineering Bureau, he said that 26.7% of the 2 million square meters Olympic project used green energy such as renewable energy. 168 the energy saved by building energy-saving projects is equivalent to reducing 200,000 tons of carbon dioxide emissions every year. The reporter learned that some new environmental protection and energy-saving technologies and equipment will go out of the Olympic venues in the future to benefit the general public.
The Olympic Village witnessed the Green Olympics.
Energy conservation and environmental protection are exemplary.
The Olympic Village of Beijing Olympic Games fully embodies the three concepts of "Green Olympics, Hi-tech Olympics and People's Olympics" in both design and construction projects, and pursues the harmony and unity of humanity, architecture and environment. The Olympic Village not only shows the world the characteristics and high-level achievements of Beijing's Olympic construction, but also becomes a model for Beijing to realize a livable city and establish a "green home".
Green lighting technologies such as solar street lamps, courtyard lamps, lawn lamps, light pipes and LED building lighting installed in the Olympic Village add luster to the bright Olympic night. The Olympic Village also gives the five Fuwa five meanings of using renewable energy (heat energy, cold energy, light energy, geothermal energy and wind energy) to build a conservation-oriented society (water saving, material saving, electricity saving, land saving and energy saving). As the service center of athletes during the Games, this beautiful and harmonious micro-energy-consuming building integrates appearance, practical functions and natural environment, showing the essence of three concepts of athletes' leisure and browsing. After the game, as a kindergarten, inspire children to love science and enjoy nature. This is the most showy green building.
The Olympic Village adopts the ecological sewage treatment technology of landscape greenhouse to treat part of domestic sewage and supply water for waterscape. This technology uses the principle of self-purification of natural water body and the food chain of animals and plants to establish a water ecological balance system to comprehensively treat domestic sewage. There is no need to add chemicals in the operation, which will not cause secondary pollution to the water body, and the system will run without noise, odor and solid waste.
In order to ensure a good indoor environment, during the construction of the Olympic Village, building materials (including cement products and concrete, additives, wall materials, peeling products, building sanitary ceramics, doors and windows, waterproof materials) and decorative materials (including wood-based panels and products, coatings, paints and adhesives) were tested and pre-controlled according to the requirements of green materials for the Olympic Project, and all environmental protection indicators exceeded the national standard E 1.
High-quality titanium dioxide paint and wall paint with new environmental protection technology selected for the Olympic Village can effectively increase the painting area, and are scrub-resistant, stain-resistant and long in service life. The content of heavy metals, VOC and formaldehyde is much lower than that of ordinary paint, and the pollution is close to zero. The surface of paint film is smooth and greasy, and the smell is fresh and lasting. An efficient, non-toxic antibacterial and mildewproof agent is added to the paint, which can prevent the propagation of mold on the surface of the paint film and provide more health protection.
In the Olympic Village, the hot water faucet in each bathroom and kitchen is provided with a vertical circulating vertical pipe to shorten the length of the horizontal branch pipe as much as possible, and the hot water is continuously circulated in the vertical pipe, so that the hot water can be discharged quickly when the hot water faucet is opened, which can avoid wasting cold water for a long time after the hot water faucet is opened.
In addition, the Olympic Village has implemented 36 concepts in energy conservation and emission reduction, such as: reclaimed water heat pump cold and heat source system, centralized solar domestic hot water system, photovoltaic panels, light tube lighting, water-saving facilities and rainwater collection facilities; At the same time, such as paving construction roads with steel slag, spraying dust with settling water, and using permeable bricks. , have reached the goal of energy saving and environmental protection to the greatest extent.
