The embodiment of low-carbon concept in the World Expo

Low Carbon Expo is a slogan put forward by the Shanghai World Expo.

The Crown of the East Under the three themes of "low-carbon, harmonious and sustainable cities", the Shanghai World Expo attempts to answer the urbanization problems caused by the industrial revolution. Achim Steiner, Deputy Secretary-General of the United Nations and Executive Director of UNEP, believes that Shanghai has set new standards in many aspects for the theme of "Better City, Better Life". The picture shows the "Crown of the East" of the China National Pavilion, which is taken from the brackets, an element in ancient Chinese wooden structures. The "China Pavilion Garden" on the roof of the regional pavilion will also use ecological agricultural landscape and other technical measures to effectively achieve heat insulation, reducing energy consumption by more than 25% compared with traditional models [1].

Exterior walls made from waste optical discs

Walking into the bustling World Expo site, the Shanghai Enterprise Pavilion is inconspicuous, but its translucent exterior walls attracted the attention of reporters. "This is polycarbonate made from recycled waste optical discs. Using it as a building facade not only saves energy and is environmentally friendly, but also adds artistic beauty." said Gu Shuhang, general manager of the Shanghai Enterprise Pavilion project. "Environmental protection concepts" can be seen everywhere in the Expo. The 50,000-square-meter ecological green wall is the largest in the world; the 4.6-megawatt solar generator capacity ranks first in the country; the 420-kilometer rail transit network, more than 1,000 new energy vehicles, and the public transportation in the park have achieved "zero emission" ”… It’s eye-catching that Shanghai has put a lot of effort into building a “low-carbon World Expo”. In addition to Chinese exhibition halls, venues from participating countries also fully display the beauty of "low-carbon life". At the entrance to the spiral ramp of the Danish Pavilion, which covers an area of ??3,000 square meters, a unique exhibit - bicycles - is prominently displayed, as well as a pond that will soon be poured into the clear water of Copenhagen Harbor. After the World Expo opens on May 1, visitors can experience the Nordic "low-carbon life": ride a bicycle, or take off your shoes and socks, soak your feet in the clear sea water and enjoy the coolness of summer. The green building technology of the German Pavilion, the environmentally friendly rattan materials of the Spanish Pavilion, and the London zero-carbon community, which is like a "primitive cave" without water, electricity, or heat - low-carbon technologies have decorated the Expo site beautifully.

The world's largest single-area solar roof

The Shanghai World Expo Theme Pavilion's roof solar panel area reaches more than 30,000 square meters. It is currently the world's largest single-area solar roof, with an annual power generation of It reaches 2.8 million kilowatt-hours, which is equivalent to the total electricity consumption of more than 45 million residents in Shanghai for a year. It can reduce carbon dioxide emissions by about 2,800 tons every year, which is equivalent to saving more than 1,000 tons of standard coal every year. The roof of the Shanghai World Expo Theme Pavilion was selected as the world's largest single-area solar roof by the China World Records Association.

The world's largest ecological green wall

The 5,000-square-meter ecological green wall on the facade of the Shanghai World Expo Theme Pavilion is the world's largest ecological green wall. It is also a major symbol of energy conservation in the exhibition hall. The green and insulated exterior wall will effectively block radiation in summer and reduce the air temperature near the exterior wall surface. In winter, the exterior walls will form a layer of insulation that reduces wind speed, thus extending the life of the exterior walls. The roof of the Shanghai World Expo Theme Pavilion was selected as the world's largest single-area solar roof by the China World Records Association. The wall of the Shanghai World Expo Theme Pavilion was selected as the world's largest ecological green wall by the China World Records Association.
