Method for a simplified description of daylight quality in simple rooms in dwellings, Phase 2
The project aims to develop further the basis for a method that by means of 8-10 parameters can give a simplified assessment of the daylight quality in rooms in dwellings. The simulation program Radiance is used as a tool for analysing and assessing the quality parameters. The analyses are limited to 3 relatively simple room configurations, viz. a room sidelit from a perpendicular window in the facade, a room with a skylight and a room with a dormer window.
The analyses include the following parameters: 3 dimensional illumination (calculated in 6 directions in the middle of the room), shadow scale i.e. studies of how the light falls on a sphere placed at selected points of the room (cf. Sophus Frandsen), surface areas with unacceptable 'luminance increment x area x time' and the Daylight Glare Index (DGI) and Luminance Difference Index.
The results will be published in an SBi publication.
