Visit Roof Garden To Experience Three-Dimensional Greening

The Roof garden of Saudi Arabia museum is very distinctive.

Scientific and technological innovation is the eternal theme of World Expo. World Expo, Shanghai, has shown the concept of sustainable development that science and technology lead and support "Better City and better life". Have you noticed these technological highlights during the visit? In order to give readers a better understanding of the technology displayed in Shanghai World Expo, this newspaper and Shanghai World Expo science and technology promotion center will launch the Expo technology travel column today, and invite experts to interpret the wonderful technology of Expo venues from the aspects of environment, energy and new materials.

Environmental technology is a science and technology field highlighted in World Expo, Shanghai.

The beautiful Roof garden, the ingenious interior microclimate system, all need tourists' personal experience.

Professor Li Guangming, deputy director of Shanghai World Expo science and technology promotion center and vice president of the school of environmental science and engineering, Tongji University, briefed reporters on many highlights of Expo environment technology and designed a "Expo environment technology travel" program.

More than 80% of the venues are

According to Professor Li Guangming, visitors should not miss the "Fifth Facade" - a three-dimensional afforestation based on Roof garden when visiting various pavilions in Expo Park.

In the more than 200 venues, more than 80% of the venues have made rooftop greening and indoor greening, which is worth stopping.

At the China Pavilion, the overall greening layout is divided into several levels. There are ground greening and roof greening of the provincial and municipal buildings, known as "new Kyushu Qingyan", outside the pavilion and on the roof of the stadium.

At the entrance of the exhibition area, there is a "1.8 meter" hedgerow, which is inserted into the leaves of Euonymus japonicus after two times of preservation. It can keep fresh and luxuriant for one year.

Entering the exhibition hall, visitors can see an area of 100 square meters of green green wall, it is composed of special varieties of colorful leaf plants, colorful colorful.

In the area of Hongkong, there are also Roof garden pavilions and Saudi Arabia Pavilion.

At the top of the Hongkong Pavilion, visitors will pass through a forest area composed of 40 trees, and then walk to the wooden viewing gallery to enjoy the artificial waterscape and feel the "wetland ecological zone" of Hongkong.

In Saudi Arabia, Roof garden with palm trees has just opened up and has a strong Arabia style.

In the B area, the theme pavilion is the highlight of the three dimensional greening in the Expo Garden.

The vertical and ecological greening wall of the museum is 5000 square meters. It is the largest ecological wall in the world.

The roof of Singapore Pavilion is a delicate tropical garden. Besides the usual tropical plants, there is a new species of Dendrobium orchid bred in World Expo, which is "new Shanghai Symphony".

In the C area, the Swiss Pavilion has a grassy roof of about 4000 square meters, showing the rural scenery of Switzerland. The green roof is also the foundation of the top cable car.

In the Romania Pavilion, which looks like the green apple, the apple cutting block is designed to be a green tree stand. The 8 containers planted with "flower leaf water wax" trees form the natural barrier of the grandstand.

In the French Pavilion, up to 20 meters above the whole indoor space, the "green pillar" is hanging, so that all visitors entering the museum will be shocked.

Li Guangming said that the green pillar is planted in the forming of three-dimensional containers of diverse green plants, to express the French's pursuit of unlimited green space concept, but also reflects the superb green wall technology.

According to reports, these green columns have adapted many kinds of plant species suitable for Shanghai climate conditions, such as Euonymus japonicus, Stipa microphylla, and jade hairpin.

In addition to ornamental plants, edible vegetables are also the main characters of some Roof garden pavilions.

For example, on the roof of the New Zealand Pavilion, there are many kinds of vegetables that residents need daily.

In the US, a vegetable garden has been built. Its green roof technology will produce cooling effect of heat energy and slow down the discharge of rainwater, so as to achieve the effect of irrigating vegetable garden with rain.

During the visit, many indoor microclimate and environmental systems in the exhibition hall deserve attention.

The Japanese pavilion has a vertical circular breathing column, which resembles their antennae on the purple silkworm island.

These breathing columns are integrated into the internal structure of the building, forming an environmental circulation system.

The system can collect sunlight, collect rainwater and keep the natural circulation of air, so as to reduce environmental load.

Entering the Italy Pavilion, the indoor microclimate environment system is concentrated in the entrance hall.

The glass curtain walls and roofs of the pavilion use special high-performance glass. Compared with ordinary glass, they can absorb solar radiation and block half of the heat input, which helps to save energy and reduce consumption and reduce the use of air conditioning.

Solar panels, integrated with glass curtain walls, can not only shade the sun, but also generate electricity.

When you come to Pudong Park, visitors can go into the pavilion to see if the indoor air is fresh.

According to the introduction, the Yuanda hall thoroughly ventilating 3 times per hour, adopting the original new fan with electrostatic precipitator. When the outside air enters the room, 99.9% of the dust and bacteria will be filtered out.

Visitors can also take a look at the Madrid case hall in the best practices area of the city.

The "Air Tree" there is a temperature control room built by environmental technology. But it is not a traditional air-conditioned room, but a cool and comfortable environment with a diameter of 7 meters. The temperature difference between the "tree" and the "tree" can reach 5 - 8 degrees.

In addition, during the visit to the Expo Park, visitors can also visit the beach park in C area and feel the scenery of the fish jump. It is like the example of Bailian Jing and Chengdu living water park, which is a model of urban water environment governance.
