Onto the roof, Journey Into Amazing Caves

In addition to expanding the use of the roof space, there is an advantage of abundant sunshine, do not worry about lighting issues. Thus, green roofs, rooftop solar controller is through the distance from the sun strengths to achieve people's environmental dreams. The popularity of the concept of green roofs, all the major international cities are popular since the hanging gardens.

Engaged in the cause of more than ten years green roof green roof Association Secretary-General Wang Xianmin world view, green roofs can cure many of the "modern urban disease" - the winter haze, summer urban waterlogging and lead to high temperature heat island effect, can be Green roofs relief, because green roofs help purify the air, rainwater harvesting, cooling insulation.

According to Wang Xianmin observation, Germany is the green roof of the "leader", as early as 1982 began this legislation. Later, Japan, Singapore, the United States, France, are followed, from legislation to encourage green roof. Today, Japan's rate of new construction of green roofs is 100%.

In the specific practices, the German legislation, reported that construction of new buildings must have green roofs, even in rural areas, too, tend to give developers and the government subsidy of 50% to 100% of the green roof construction fees.

About green roofs, although China is currently no legislation to be encouraged, but Yang Baojun said, as long waterproof, load problems can be resolved, in principle, is encouraged. And Wang Xianmin believes that developers should take up this responsibility, after all, "real estate construction costs greening costs account for only 1/1000", and the construction of a green roof waterproofing system, you can also extend the life of the house, "This is the sustainable development vision. "

In addition to direct green outside, the roof construction of solar energy projects, make full use of clean energy, but also the roof is a major contribution to environmental protection. Or in Germany, thanks to January 1999 from the implementation of "100,000 Solar Roofs Plan", residents have set up buy solar panels on the roof, the electricity in addition to their own use, the remaining can be sold to the grid company, and received power fees. According to 2010 data, relying on the rooftop power generation, some German families can earn 1,500 euros a year.
