Overshadowing, or loss of sunlight to existing premises, is analysed using annual probable sunlight hours (APSH). These analyses are generally carried out by specialized engineers who focus on the performance of individual rooms. Rays of light are emitted from a light source and illuminate objects. Today, the trend is toward computer analysis to provide daylighting design information and feedback immediately to the design team. Daylight Visualizer can accurately predict daylight levels and the appearance of a space lit with natural light, prior to realisation of the building design. This "backward" approach to tracing the rays of light from their end point to their source is most common, but there are other methods of raytracing calculations. Backward raytracing follows a light ray in the reverse direction, from the eye to the light source. New computer software for daylighting analysis contains new more advanced metrics for daylighting (Climate Base Daylight Metrics-CBDM). Merlin - Exploratory Data Analysis Program. 31.
