Conduct a lighting audit of your school

Energy efficient lighting helps to lower the school’s energy bills and carbon dioxide emissions. Each light bulb might only use a small amount of energy, but a school will have a number of light bulbs in every classroom, corridor or hall - there will even be lights outside!

Newer LED (or Light Emitting Diode) light bulbs use up to 90% less energy than traditional incandescent light bulbs - which were invented over 100 years ago! Older bulbs waste a lot of electricity as heat - the bulbs get very hot while they are on. They also tend not to last as long as LED bulbs, so it can cost a lot of money to replace them.

1. Speak with your caretaker first to see if your school already has LED bulbs. If your school has a range of different types of bulbs, your caretaker might be able to show you the different types and help you to recognise them. Or they might be able to walk around with you as you do your audit.

2. Count the number of lights in each classroom, corridor or other areas in your school. Record what you find in the recording sheet. You might not be able to see the bulb, it might be hidden behind a panel, try to give each type of light you find a category. What other sorts of lights can you find? Are there any which need to be left on all the time?  You can use our recording sheet or make your own.
