As the world grows ever more automated, the use of intelligent lighting control systems is becoming a great option for new construction projects.


The objective of all lighting control systems is to minimise the unnecessary use of electricity, which is also a key element of Part L compliance for commercial projects. So how can we improve energy efficiency of lighting systems beyond simple manual switches and PIR sensors?


In the same way that PIR occupancy sensors ensure lights are switched off when a space is unoccupied, photoelectric sensors can be used to ensure that the lights are switched off when a space is adequately daylit. This type of system is often used externally within car parks, porches and shop windows, but they can also be used as part of an indoor circuit and are particularly effective where there are large areas of glazing allowing daylight into a building space.


Daylight and occupancy sensing coupled within a single device known as a multi-sensor ensure that artificial lights are only switched on when necessary, saving electricity. These systems can also be used in conjunction with dimming controls to further improve efficiency, since dimmed lamps in partially daylit space operate with a lower power output.


Sustainability consultants can advise how the specification of photoelectric controls can improve performance within SBEM calculations for your commercial project. Get in touch to find out more.
