The sky view factor is the view factor from the surface to the sky. This is the ratio of the diffuse sky radiation received by the surface to that which would be received by the same surface if it were completely exposed to the sky.
The most important geometric effect is that of the sky view factor (SVF). The present study has investigated the effect of SVF on micro-climate, focusing on the solar radiation in the city center of Dhaka, Bangladesh. The relation between SVF and radiation has also investigated for different seasons.
