Abstract

Natural light is highly variable and limited in time and space. In situations where it is not or insufficiently available, Virtual Natural Lighting Solutions (VNLS) can be promising. This paper presents research based on computer simulation to explore the space-gaining potential of VNLS in offices, healthcare facilities, and industrial halls. The models are developed and simulated using the Radiance lighting simulation tool. The space-gaining potential of the virtual windows is determined by comparing space availabilities, i.e. the percentage of space with workplane illuminance more than a certain level, in situations with either real windows or virtual windows only. Criteria concerning visual comfort glare indices and luminance ratios are also considered. The paper demonstrates a comparison of space availability and visual comfort in some building types with virtual windows, compared to those of real windows with CIE overcast sky. The building type with the largest space availability and relatively low glare indices will be considered as the one with the biggest potential.
