Daylight computation requires the use of climate-based data as well as the correct treatment of lighting exchange, both in the interior and exterior environments, which is frequently not considered or roughly approximated. We present an efficient method for computing daylighting that considers the exterior components accurately. We analyze the influence of the exterior components depending on the number of light bounces, which may benefit early stage projects by providing a useful analysis for understanding the different daylight contribution sources.
