From simple housekeeping tips to detailed advice on upgrading equipment and systems, this section will help you save energy by making your lighting systems more efficient.

The lighting technology overview (PDF) guide gives an introduction to the main lighting energy saving opportunities for businesses.

Top 3 recommended* carbon saving lighting projects

Use energy efficient lamps

If you have fluorescent tube lighting, changing from T12 tubes to T8s will bring energy savings of 10%. Upgrading lamps and fittings to T5 will bring even greater savings and will retain a high light output. This short video explains how to replace T12 tubes with more energy efficient lighting.

Install occupancy sensors

Why light empty spaces? Occupancy sensors, which switch off lights when a space isn’t being used, can reduce lighting costs by 30%.


Install daylight sensors

Lighting a space artificially when daylight is already doing the job is a waste of energy. Light sensors (photocells) can switch off or dim artificial lighting when there is sufficient daylight. To see if these controls would work for your site, watch the video.
