The Research Of Current Situation About Green Roof In Beijing

The Research of Current Situation about green roof in BeijingGreen roofs can reduce the effectiveness of heat island, reduce soil erosion, improve the micro-environment, at home and abroad, has been fully demonstrated to play a huge role in its ecological aspects. The green roof design is different from the green on the ground, it is different from the traditional roofing practices, combined with both an integrated structure, building, landscape, equipment, professional overall system design but also the difference between requirements in the design.To conduct field research on green roofs case of Beijing, Shanghai, Guangzhou and other places, especially in Beijing and many cases a careful study found that many problems exist. Combination of domestic and international green roof technology and case studies, and related journals, papers, patents, books, specification, construction, manufacturers and related professional research data, to investigate, analyze, compare and summarize. Paper the main problems in the development of green roofs in Beijing, study, ask questions and give advice on the measures.Policy to promote green roof development at home and abroad, the Beijing rooftop greening policy recommendations, structural design, structural systems, security design, irrigation systems, drainage systems and load, inductive common problems, and to identify suitable solutions and responses; provide a basis for future green roof design. To analyze the reasons for slow development of the existing roof, and summarizes several appropriate type of design, to provide a reference for the promotion of green roofs and upgrading of existing buildings; sloping roof construction slope and soil erosion problems, according to a different slope to find the better green roofs. Maintenance is not conducive to plant growth and public participation factors were aggregated to provide a better solution. Simple, garden-style green roofs and green renovation of existing buildings costs for cost-calculation, analysis and research, given the scope of the cost of green roofs.
