A daylight simulation is a computer-based calculation of the amount of daylight inside or outside of one or several buildings. Common daylight simulation outputs are either luminance distributions, i.e. photorealistic high dynamic range (HDR) images, illuminances at key positions within a scene, or various “daylighting metrics” that have been derived from the earlier two types of data.
In a predominantly sunny climate, it can be instructive to test indoor illuminance levels under a clear, sunny sky. For such an analysis, one would usually use the CIE clear sky model. A typical time of interest is, for example, noon during the winter and summer solstice (see section 5.5, Daylighting Metrics, below). The front cover of this document shows a hybrid simulation output generated with 3ds Max Design in which a false color grid of illuminances is overlaid on an HDR image of a space.
