Abstract

AbstractThe aim of this study was to understand the influence of the architectural morphology on thermal environment of an urban residential district in severe cold region by taking a typical urban residential district in severe cold region as research object. The numerical simulation was carried out to study the buildings’ impact on the local thermal environment under the different height in the center area and evaluate the contribution of wind speed and temperature to microclimatic effect based on the joint action of the wind velocity, temperature, and solar radiation in this residential district, and find the varied rules of the wind velocity and temperature by the change in the center regional buildings’ height. In addition, the outdoor personnel comfort in this residential district was analyzed by the principle of estimation on aeolian environment. The results can provide theoretical reference for the buildings’ planning and prediction of thermal environment in the severe cold area and has proved the feasibility of buildings’ planning based on the microclimatic effects.KeywordsCFDSevere cold regionThermal environmentPrinciple of estimation on Aeolian environment
