Sustainable Development Applications on Urban Environment Based on Climate Regulation

Urbanization is the inevitable outcome of development of society and economy, which necessarily brings about city problems and environmental problems, and intensifies the contradiction among population, resources and environment. In recent years, with the rapid development of urbanization, the municipal area and population of city increase by degrees in China, industry and economy growing rapidly, and the sources of energy were continually consumed. Large amount of heat was discharged, which results in the worse situation of urban environment of metropolis. City climate, as one of the important component of city environment, plays an important role in affecting city space environment and urban planning. Based on protecting the urban ecomanagement, It is of great significance to study the acclimated urban planning and design in order to create comfortable environment and energy saving environment, which is one of the strategies of city sustainable development principles. In this research, Computational Fluid Dynamics (CFD) is applied to study the mutual relation between city climate and urban planning. Taking the Hanyang new city of Wuhan in China as a study case, this paper introduces how to apply the CFD stimulation of the digital model of metropolis to thermal environment study. According to the simulation, the analysis is given, which can be used to optimize the design continually and explore the regular pattern to make the project design improved. Based on these analysis, the problems related to the architecture and urban design are explored, which plays a very important role in studying for the thermal environment of metropolis and investigating the adaptability of different city shapes, building shapes to the climate.
