老旧住区建筑布局对微气候环境的影响研究OA

Under worsening global climate change,improving the microclimate environment in old residential areas is crucial for improving the quality of life of the residents in these areas.This paper simulated three building layouts in a typical old residential area of Urumqi by using ENVI-met and compared their differences in microclimate environment.Results show that row layouts alternate thermal comfort and discomfort zones,with relatively high overall thermal environment stability.Mixed layouts disperse heat accumulation via staggered buildings,avoiding sustained high-temperature zones,though localized discomfort persists.Enclosed layouts form continuous shaded corridors,but accumulate heat in central courtyards.In addition,based on the simulation results and the identification of the current modifiable elements,this paper further proposes the strategies for the optimizing the design under the goal of improving outdoor thermal comfort.
