Lighting controls

Abstract

When electricity was cheap, manual block light switching on a first‐in, last‐out basis was acceptable, with the result that many buildings were lit for up to 15 hours a day irrespective of the contribution of daylight or even of the presence of people. Behavioural studies at the Building Research Establishment (BRE) have shown that switching on occurs at the start of occupancy if the daylight is judged to be insufficient, but switching off only occurs when the space becomes empty. In other words, while people are very good at turning lights on when they feel they need them, they are very forgetful when it comes to switching them off when they are no longer required.
