Heating

General information on heating and cooling:

  • The optimum office temperature is typically 19°C to 21°C
  • The legal minimum temperature for offices is 16°C
  • Comfort cooling should not be set to come on below 25°C
  • A 1°C reduction in room temperature can save 6 to 8 percent on heating costs and CO2 emissions
  • Air conditioned buildings use about twice as much energy as naturally ventilated ones. Even small 'comfort cooling' systems are energy intensive to run

The University spends in excess of £2.5m on heating and cooling buildings. Many of our buildings have sophisticated controls maintaining conditions at the required comfort levels. Currently the University is investing in a number of energy saving projects including a programme of control upgrades which will make the systems more efficient.

Due to the nature of many University buildings it is hard to achieve a consistent level of heating from room to room, building to building. In addition, everybody has different temperature tolerances making getting the 'right' temperature hard to achieve. However there are a number of actions you can take to help save energy and improve your comfort levels.

Energy Saving Actions:

  • Close doors and windows when heating and air conditioning is on
    • Report doors and windows that do not seal correctly when closed to ESS customber services on ext. 7171
  • Dress appropriately for the weather conditions
    • As we all feel cold to different degrees one of the best ways to maximise personal comfort is to wear the most appropriate clothing for you
    • As different rooms vary in temperature across campus it is advisable to wear layers.
  • Familiarise yourself with local heating controls
    • Some office radiators will have thermostatic radiator valves (TRVs) which you can alter.
  • Do not use portable electric heaters
    • Using electric heaters is not only much more expensive but is also responsible for greater CO2 emissions. If your work area is too cold (typically lower than 19°C) please report this to ESS customer services on ext. 7171 so that the issue can be investigated. Please remember if we don't know about it, we can't do anything about it!
  • Request a room thermometer strip
  • Ensure that heating and cooling systems are not running at the same time
  • Report occupancy patterns
    • Heating (or cooling) empty buildings or unoccupied areas is a waste of energy. Likewise if your building is taking too long to heat up the heating controls can be adjusted to turn it on earlier.
  • Report heating issues
    • If you think there may be a fault with the heating or cooling systems in your area please report it on ext. 7171.
