The energy management of artificial lighting use

Abstract

Drawing on the understanding of occupants' lighting use gained from previous BRE behavioural studies, the potential benefits of controls for electric lighting, such as energy saving or reduced installation costs, are described on a qualitative and, where possible, a quantitative basis. The paper reviews the options available for controlling lighting use, exploiting daylight and occupancy linking and various methods of central control including mains signalling, low voltage communication and remote ('wireless') signalling, discriminating between those that are technically feasible and those that have been developed from feasibility to 'off the shelf' systems.
