Did you know?

If everyone at the University turned off one light for one hour every working day we could save over £11,000 per year and 50 tonnes of CO2 a year, that is enough to fill over five double decker buses every week.


Please do not compromise health and safety standards when trying to reduce lighting levels.

Lighting accounts for around 20 per cent of University energy use. While the University is investing in lighting projects, such as fitting automatic motion sensors and replacing old, inefficient fittings with new energy saving options, a big part of the solution is simply turning off lights when they are not needed.

Energy Saving Actions:

  • Don’t leave lights on in unoccupied areas
    • Last one out at the end of the day? Switch off the lights!
    • Last one out of a meeting room? Switch off the lights
  • Switch off lights that are not needed
    • These could be in offices, corridors, meeting rooms, toilets & kitchen areas (to name a few!)
    • Don’t switch on all lights when only a few are needed
    • Use local desk lights if only a few people are in the building
  • Always make maximum use of daylight
    • Natural daylight is nicer to work in as well as carbon and cost free. If you get uncomfortable glare on your computer screen consider rearranging your desk top (where possible) before closing blinds and turning on the lights
  • Reduce decorative lighting wherever possible
  • Report faulty lighting promptly
    • A flickering tube uses more electricity as well as being very distracting
    • Report faults to ESS Customer Services on Ext. 7171.
  • Assign a responsible person
    • To turn off lights in communal areas including shared offices, corridors and kitchens. Ask colleagues to establish who is often last in and see if they can make it part of their routine.
  • Label switches
    • Label multiple banks of light switches. Rather than turning on all office lights you can turn on just the ones you need (and take responsibility for turning them off when they are no longer needed).
