Daylight simulations are useful for assessing and optimizing daylight supply and visual comfort levels in buildings. Along with the site's key parameters, such simulations take account of the characteristics – in terms of geometry and materials – of the building's envelope and interior. The aspects that such simulations can reveal include shadowing by neighboring structures, the building's self-shadowing, and the light conditions related to complex facade systems and room structures. Such aspects are especially significant in that intensive daylight use can significantly enhance a building's overall energy efficiency.
Findings from daylight simulation (distribution of daylight factors and of daylight supply factors) are of use in optimizing planning. They make it possible to plan and assess indoor comfort levels pursuant to the following standards:
