A Cold Features Green Building Roof Landscape Design

People’s living space is getting smaller and smaller, will function as much as possible of the limited space expansion is important work. On the roof planting vegetation, is one which can save urban space but also a good way to increase the green area. Now, because the climatic conditions of human deforestation, trees have become less and less, and now more and more cars, many of the industrial exhaust emissions, the consequences of dust storms frequently struck, fit for human survival more to the worse. However, the tall buildings, asphalt roads are also more and more, in order to increase the green area can only be powerless, green on the roof, which is equivalent to the overhang on the ground greening, green space has increased, the climate would become good, the urban environment and better able to promote the public demands can be described as beneficial rather than harmful.In this paper, the analysis of the cold regions, the existing building roof, behind the paradox of the environmental advantages of green design low-carbon and the development of existing traditional architectural roof design, analyze the causes and impact of the urban environment, comprehensive developed countries andregion as well as China’s economic development and rapid mature experience, case analysis and transformation of design on the building roof in cold area, have a certain role in promoting the development of energy conservation and green building is a cold building roof design to achieve energy consumption and reduce environmentalan effective means of destruction.
