Modelling the Daylight Levels Produced in Rectangular, Side-Lit Rooms by Vertical Windows Containing Clear or Body-Tinted Glazing
The increasing importance of daylight as a means of reducing the overall energy consumption within a building is discussed. The conflict between statutory limits on percentage area glazing and the possible increased use of artificial lighting is also considered. The basic theory of natural daylighting in buildings is described, together with the various sky luminance distribution types available for quantifying internal daylight levels. The mathematical theory of a new daylight computer model developed within the Department of Building Science is given. This new model enables daylight levels to be determined rapidly for small windows in relatively thick walls, for windows of varying KL value and for obstructed sky views. A comparison is made of the present daylight model with other existing computer programs and the results from a scale model under an artificial sky. Finally, a description of how to use the new daylight model is presented and an example of a typical run using the model produced.
