The Analysis of Reactive Factors between Architectural Envelop Condition and Urban Microclimate

High-density has become an inevitable tendency of urbanization. Contemporary buildings grow higher and denser; high-rise and high dense buildings have become the main method of newly-built buildings. The reaction between street canyon and urban microclimate should be studied scientifically. The buildings envelop factors include the material properties such as smoothness, albedo, while the envelop morphology factors include entasis, porosity, stepped podium and stilt buildings. These building factors studies are conducted to clarify the effects of building geometries on urban microclimate, as well as the reaction among the factors themselves. The multiple-factor study result provides effective mitigation strategies to alleviate UHI effect and to conduct proper environment control.
