The analysis of urban Sky View Factor calculation based on geometric form

Previous research has shown that there is a clear relationship between the urban morphology on one hand and local solar irradiance air temperature other hand. In order to describe climatology its spatial variations sky view factor (SVF) plays key role. This fraction of visible provides an indication street geometry building density. Adding SVF as evaluation element in planning be used coordinate layout city, improve built environment, reasonably control height density construction projects, which can effectively promote refinement green cities.
