Lighting controls can give important energy savings and their reasonable provision is required by Building Regulations whenever lighting work is carried out in buildings that are not dwellings. When choosing lighting controls, it is important to take into account the type of space, how it is used and the amount of daylight available. This Digest explains how to do this and describes the common types of control and how to calculate energy savings.
