Abstract

This paper examines potential applications of the sky view factor (SVF) regarding two- or threedimensional sites. First, the concepts of the radiation budget, Lambert's cosine law and hemispherical description of radiating of en vironments are introduced and connected to the sky view factor. Based on a comparison between different models and methods which calculate the SVF, the paper then focuses on two different kinds of SVFcalculation depending on the type of analyzed site. It is assumed that in case the point of interest represents a flat, two-dimensional area, it makes sense to include the cosine law whereas in case the point of interest represents a solid three-dimensional object the application of Lambert's law could have to be applied in another way. It is shown that the inclusion or exclusion of the cosine law results in different SVF values. It is concluded that depending on the type of surveyed area, the application of a 2D- or 3D-sky view factor should be considered in order to get a better approximation of the radiation fluxes.
