Environmental Design Of Greening Roof In Changsha

Greening roof can improve the indoor thermal environment while make it more beutiful.For a long time,domestic and foreign research on roof greening usually separates the roof landscape design from the indoor thermal environment design,resulting in the waste of landscape resources and poor indoor thermal environment.Therefore,it is of great scientific significance and practical value to combine outdoor landscape with indoor thermal environment design.In this paper,based on the geography and climate of Changsha,the following studies were carried out on the basis of comprehensive environmental design:First of all,through the basic theory of domestic and international research literature research and Changsha roof greening on-the-spot investigation,pointed out the main problems,clarify the research direction,and summarizes the environmental design elements and types of roof greening module.Secondly,combined with the existing main problems of roof greening,discusses the landscape design of the module,especially planting module in the selection of plant species,planting pattern and color collocation is studied;at the same time with Ecotect Analysis and Design Builder simulation,the environmental impact of design module on the indoor thermal environment is analyzed and quantified the best combination,in order to module.Third,considering the comprehensive environmental design based on the outdoor landscape combined with the indoor thermal environment,to ensure that the main ornamental objects and landscape types remain the same or similar circumstances,the environment design module as insulation and energy saving effect under the minimum load combination or the corresponding transformation mode,to adapt to different types of ornamental and ornamental type bearing three,recreational type roof.Fourth,the analysis of the existing green roof design case and the corresponding economic feasibility,for the promotion of roof greening to provide an effective theoretical basis.This paper provides a design method for the comprehensive environmental design of roof greening,and has a high reference value for the roof greening design under the same climatic conditions.
