Save precious resources for where they're needed

Recommended temperatures for public sector buildings

  • Offices 19-21°C
  • Classrooms 18°C
  • Sports hall and corridors 15°C
  • Areas for very young children 21°C
Developing a temperature policy can help to manage your heating use over time

Public sector heating systems

  • Switch off heating for the last hour of the day - the building should retain its heat for that time
  • Use time switches so heating is only on when the building's in use
  • Don't use extra electric heaters, which are very expensive to run
  • Encourage staff to use window blinds to retain heat in winter and keep it down in summer
  • Regularly service boilers to retain efficiency and consider replacing units over 15 years old

More ways to save

Adjust your routine at your workplace and you could start saving money on your business energy bills. 


  • Opening window blinds to utilise daylight could reduce lighting bills by 19%
  • Use movement detectors, time switches and daylight sensors
  • Encourage staff to switch lights off when they're not needed
  • Install energy-efficient lights - using the right lights could cut your lighting costs by up to 80%
If you have a heated indoor swimming pool, keep it covered when not in use.


  • Hot water should be stored at temperatures above 60°C to avoid bugs like legionella
  • Cold water should be kept at a maximum 20°C
  • Ensure pipework is well insulated to prevent heat loss

Fitting taps that turn off automatically (percussion taps) can lead to major energy savings

Air conditioning

  • Don't waste energy by heating and cooling areas at the same time
  • Switch off heating in office areas when it reaches 20°C
  • Only turn on air conditioning when the temperature is over 24°C
Regular air-conditioning services help keep your system running efficiently


  • Install variable-speed drives in your fans
  • Ensure air recycling is optimised, particularly when there aren't many people around
  • Consider investing in high efficiency equipment for your heating, ventilation and air conditioning systems
Variable-speed drives can reduce the running costs of a fan by up to 40%

Electrical equipment

  • IT equipment burns energy, even in standby mode
  • Encourage staff to switch equipment off when not in use
  • Use the energy-saving features on things like monitors and printers

Turning computers and monitors off at night can save £35 a year per desk
