Large-scale application of solar power; more than 1,000 new energy vehicles are used in the World Expo to help Shanghai World Expo's transportation achieve the goal of “zero emissions in the park and low emissions around the parkâ€; centralized use of semiconductor lighting called “green light source in the 21st centuryâ€; Energy conservation and emission reduction targets, resource recycling... At the beginning of the World Expo preparation, in addition to demonstrating the inventions and inspirations of the countries and enterprises in the cutting-edge fields, the World Expo planning and construction, energy, environment, operation, display and In terms of safety, it has also adopted technological innovation and realized the concept of “Science and Technology Expo and Ecological Expoâ€.
The application of a large number of the world's most advanced high-tech means to the 2010 Shanghai World Expo will be the biggest highlight and charm of the Shanghai World Expo. The Shanghai World Expo, which embodies the strength of the global scientific and technological community and the corporate world, has brought the "Science and Technology Expo" to an unprecedented height.
The following light of future urban technology that has been applied to the Expo venues may appear in human life in the near future.
Solar energy into the main theme of energy
ELCO, a global leader in the production of hot water and heating solutions, is a high-end commercial heating and hot water solution provider, ELCO, which is a green solution for system integration and building integration. supplier. The project is the only solar water heating project implemented in the permanent venue of the Expo. It is also the green renewable energy project that emerged in the state-level venues after ELCO's Beijing Olympic Village project. It is reported that ELCO's atmospheric gas boiler also won the bid for the Expo Village D plot, and the residential hot water brand Ariston also won the bid for the Shanghai World Expo B plot.
The solar water heating system integrated by the ELCO business unit is located on the top of the bus parking lot outside the Expo Center. The collector has a lighting area of ​​about 310m2 and a daily hot water capacity of 30 tons. The gas boiler is used as an auxiliary heat source. The solar water heating system of the design is a closed type indirect use of the solar water heating system, and the solar hot water is used as a primary heat medium, and the cold water is heated and used.
According to the person in charge of the ELCO brand, the system uses different priority heat storage schemes to maximize solar heat utilization; the multi-channel water supply method is in line with the irregular water use characteristics of the conference center; the entire system can save up to 35%, the system It can save 370,000 kWh of electricity every year and reduce carbon dioxide emissions by 38 tons.
“Zero emission†of new environmentally-friendly vehicle exhaust in the Expo Park
The 2010 Shanghai World Expo will achieve “zero emissions from the park and low emissions in the surrounding areasâ€. In order to achieve this goal, Shanghai World Expo will expand the use of various new energy vehicles, and more than 1,000 new energy vehicles will serve the Expo. In the Expo Park, super-capacitor vehicles and pure electric vehicles are used to achieve no exhaust and zero emissions. In the vicinity of the Expo site, hybrid vehicles are used to achieve low-carbon emissions. Among them, Shanghai Shenwo Bus Company, a joint venture of Volvo Group in Shanghai, will provide about three or four hundred super capacitor vehicles, pure electric vehicles and hybrid vehicles for the Shanghai World Expo. Shenwo's hybrid vehicle, with fuel-electric hybrid technology, has a fuel economy of nearly 30%.
According to the Shanghai Science and Technology Commission, after the World Expo, hybrid vehicles and pure electric vehicles can be used in urban public transportation systems, while fuel cell vehicles continue to study their reliability, including supporting the layout design of hydrogen refueling stations. Debut of new energy vehicles: According to the plan, 10% of the annual production of Shanghai's autos in 2012 will be given to new energy vehicles. By then, Shanghai will save 78 million liters of oil a year, reducing carbon dioxide emissions by 230,000 tons.
21st century green light source
Semiconductor lighting (LED) is called "21st Century Green Light Source", which has the characteristics of energy saving, long life, environmental protection and intelligence. The function of energy saving and environmental protection is recognized worldwide. The landscape lighting of the 2010 World Expo Best Practice Area will use this green light source as the main body of illumination, which is the first application practice of semiconductor lighting in large-scale human settlements. The square lighting of the Expo Park, the landscape belt along the river, the signage and intelligent guiding system, and the indoor and outdoor lighting of the stadium are all LED.
With the breakthrough of semiconductor lighting technology and industrial development, semiconductor lighting as a green light source will gradually replace some traditional light sources, and derive many new lighting functions, such as intelligent lighting, analog ambient light sources, etc. These technologies will be applied in 2010. At the World Expo. According to experts, semiconductor lighting can save 90% of energy without reducing brightness.
The special survey of the China Green Lighting Project Promotion Project Office shows that China's lighting power consumption is more than 300 billion degrees per year, replacing all incandescent lamps with LEDs or partially replacing fluorescent lamps, saving 1/3 of lighting power, which means saving 100 billion kWh. It is equivalent to a total investment of more than 200 billion in the Three Gorges Project's annual power generation.
Recycling resources to achieve energy saving and emission reduction
Under the coordination of the Shanghai World Expo Organizing Committee, the Ministry of Science and Technology and the Shanghai Municipal Government, the Ministry of Education, the Chinese Academy of Sciences and other 9 ministries and commissions, launched the "World Expo Science and Technology Action Plan", and identified the "Technology to protect the World Expo, Science and Technology Expo, World Expo Xing Technology" 3 aims. Now, nearly half of the project results have been practically applied in the planning and construction of the Expo Park and the future operational management system.
The Expo Park uses heat source technology to fully utilize the river water heat source and geothermal resources to provide air conditioning systems for some permanent venues in the park that are both heat and cool, no water consumption and no heat pollution. It also uses the roof of the stadium to build a large-scale rainwater harvesting system, which is used for greening and watering after purification, saving water resources; using various physical and biological technologies to purify the Huangpu River water for park greening and landscape facilities. “Energy saving and emission reduction†will run through the entire Expo Park.
According to reports, the "World Expo Science and Technology Action Plan" will strive to reduce carbon dioxide emissions from buildings and lighting in the park by 30%; drinking water 100% to direct drinking water standards; rainwater collection and treatment rate of 100%, comprehensive utilization rate of more than 30 %; engineering construction waste and garbage recovery rate reached 100%, and resource utilization rate exceeded 50%.
