| With the rapid development of China’s urbanization process, the rapid surge of the urban population and the growing scarcity of land recourses, how to effectively solve the tension between population and land has become an important urban issue. As a common building type, residential area accounts for a large proportion of city buildings and its demand for urban land resources is the highest. As a result, increasing the settlements height and floor area ratio conservation of land resources has become effective solution.Factors settlements height and floor area ratio indicators rising, new contradictions began to show: high-density living environment is difficult to guarantee plenty of sunshine and good natural ventilation. Sunshine, which mentioned before, is introduced in2002as a national mandatory standards. But the setting of floor area ratio in the residential planning and designing conditions brought out by the planning department is made according to the experience, which lack of solid proves. The failure to take account of sunshine Standards and floor area ratio indicators often occurs in practical subject.Research stage, several instances of high-level settlements Nanjing Hexi area of investigation and analysis, summarize the characteristics of the high-level land area, floor area ratio, number of layers and the apartment unit and the overall organization of form, and residential monomer combination of theory model sunshine analysis and calculations, solving the residential body and sunshine spacing quantitative relationship, and high-density arrangement method proposed standard based on current sunshine.Design stage, as the carrier Nanjing Hexi low-carbon eco-city E-3-5Lot Urban Design and Architectural Design, directly involved in the overall planning and design under the previous phase of the study results, and determine the appropriate volume rate indicators, the use of CFD software on the body the wind environment optimization, on this basis, and then at the building level overall plan designed to deepen set of sunshine environment and wind environment to good design.The research and design process made use of computer software simulation technology. It brought out the quantitative relationship between the residential and sunshine interval, the feasibility and specific operating procedure of the estimate of the floor area ratio of residential, and can be used for reference to high-density settlements design method by means of quantitative sunshine environment and wind environment.The whole thesis contains about14000words,58pictures and charts. |
