Simulation Study about Impact of Building Density on Heat Island Effect

Abstract:

Along with the rapid development of urbanization, high density city is becoming more and more common. The dense buildings cause the high intensity of heat island effect, resulting in a large amount of energy consumption. In this research the relationship between the heat island effect and the building density has been studied by CFD software with other factors such as the building height and construction shape unchanged. Through a series of simulation and data analysis it is revealed that the effect of building density on the thermal conductivity is obvious. And the study put forward the measure to alleviate the effects of the thermal conductivity by controlling building density in a certain percentage under the premise of maintaining the land use efficiency. This result can provide scientific references for planners, architects, and government management decision makers.
