Lighting See all Guides

Energy efficient lighting advice for your organisation, including guidance on energy-saving LED lighting and T5 fluorescent lighting.

We help organisations ensure their lighting systems are as efficient as possible. Our Lighting technology overview introduces the main energy-saving opportunities in this area.

Getting lighting right is important for the energy efficiency of a building and the well-being of its occupants. Up to 40% of a building's electricity use is accounted for by lighting, while the right level and quality of light improves the alertness and accuracy of those working in it.

Ways to improve your organisation's lighting include:

  • Occupancy sensors: By dimming or switching off lighting when there is nobody in a room occupancy sensors can reduce electricity use by 30%.
  • Daylight sensors: Adjusting the artificial lighting according to the amount of natural light in a room using daylight sensors or photocells can reduce electricity use by up to 40%.
  • Maintenance plan: By regularly cleaning windows and skylights you can reduce the need for artificial light. Cleaning the fixtures that contain lamps, known as luminaires, will improve their performance.
