On average academic buildings on campus use half as much energy in the middle of the night as they do during the day.

Help us reduce wasted energy by turning off lights, water boilers and other equipment when you leave for the day. Check your local toilets and cupboard lights are off too.

The buildings with savings highlighted in green on this page have beaten their targets for electricity use between midnight and 4am. Congratulations to everyone in these buildings for helping to make our university more sustainable!

Those in amber are very close - think about what else could be switched off to beat the target in future!
