BS 8206-2:2008 gives recommendations regarding design for daylight in buildings. It includes recommendations on the design of electric lighting when used in conjunction with daylight.
BS 8206-2 describes good practice in daylighting design and presents criteria intended to enhance the well-being and satisfaction of people in buildings, recognizing that the aims of good lighting go beyond achieving minimum illumination for task performance.
This revision of BS 8206-2 has been prepared to take account of the publication of BS EN 12464-1 and BS EN 15193. In particular, some of the manual calculations that appeared in the 1992 edition have been omitted and a new annex on climate-based daylight modelling has been added. There is also a new clause on daylighting and health.
Simple graphical and numerical methods are given for testing whether the criteria are satisfied, but these are not exclusive and computer methods may be used in practice. Sunlight and skylight data are given.
BS 8206-2:2008 contains:
1. Terms and definitions
2. Aims and criteria for design
3. Further design issues
4. Methods of calculation
As a code of practice, BS 8206-2 takes the form of guidance and recommendations. The aim of the standard is to give guidance to architects, engineers, builders and others who carry out lighting design.
BS 8206-2:2008 supersedes BS 8206-2:1992, which is withdrawn.
