| Abstract: | This paper focused on residential district planning process. Using GIS and SketehUp software, a common digital relief map model of a residential district was created, and the air distribution (both velocity and temperature) within this residential district was established by CFD simulation. So, the velocity and tempera-ture of the air at any location within the residential district, as well as the worse flow area and overheat area can be clearly presented. An index of micro thermal environment for the air distribution evaluation was established.Depending on a certain residential district planning model, from the air parameters of the micro environment at any location within the residential district, such as air velocity and air temperature, the index of micro thermal environment was obtained by certain principles and data processing process. By this index, the residential dis-trict planning scheme was evaluated corresponding to the thermal characteristics of the residential district. If this index is not good enough or unsatisfied, the residential district planning idea and process can be changed or im-proved accordingly in order to get a better thermal characteristics of the residential district judged by the estab-lished evaluation index system. |
