WebThe sky view factor (SVF) denotes the ratio between radiation received by a planar surface and that from the entire hemispheric radiating environment and is calculated as the fraction of sky visible from the ground up. SVF is a dimensionless value that ranges from 0 to 1. A SVF of 1 means that the sky is completely visible, for example, in a ... WebThe sky-view factor (SVF) is defined by the part of the visible sky (Ω) above a certain observation point as seen from a two-dimensional representation (see figure a). The algorithm computes the vertical elevation angle of the horizon γi in n (eight are presented here) directions to the specified radius R (b).
