The amount of daylight that will be received at any given point in a room depends on many factors. In some cases it is sufficient to consider only the illumination received direct from the sky, but for a more accurate estimate it will be necessary to take into account the light reflected from the internal surfaces and from outside surfaces visible from the windows of the room in question. It is the purpose of this Digest to explain the various steps in the assessment of indoor daylighting and the use of the various aids that have been developed to simplify what would otherwise be a long and tedious calculation.
The use of Waldram diagrams and the BRS Daylight Factor Protractors is explained.
Replaced by Digest 41 (2nd series).
