Topic planner: The Energy Saving Calendar

This topic helps you….. “identify potential energy saving actions at different time so of the year”

A significant amount of energy can be wasted by not tweaking facilities and through people not adapting their behaviour to the changing seasons and weather conditions. This checklist helps you identify key actions to ensure that energy waste is minimized at different times of the year.

Spring

Nominally the heating season ends on 30 April, but you should try to turn heating off before then, especially on warm afternoons, if the weather is mild. Once the heating season is over, this may be an appropriate time to look at lighting.

  • Check that the warm-up or pre-heat period of your building is shorter than in winter.
  • Adjust heating systems to ensure that overheating does not occur.
  • Turn down the thermostat a degree or two. You may not even notice the difference!
  • As heat losses are lower, ensure that the heating is turned off earlier in the day.
  • Re-set time switches for Daylight Saving Time (DST).
  • Celebrate Global Earth Day on April 22nd by making it a low energy at work day.
 
Summer

The longer, brighter and warmer days of summer, reduce the hours of operation of many building services. This is the time to check on the use of desk-top fans, hot water consumption, lighting etc.

  • Make sure that lights are switched off when daylight is sufficient.
  • Make sure external lights only come on at dusk.
  • Optimise daylight by opening blinds and curtains, and ensure that roof lights and windows are clean and not blocked by posters etc.
  • Try to avoid internal solar gain by adjusting blinds correctly.
  • Make sure that cooling and heating are not running at the same time.
  • Leave windows open overnight to cool the building down, if security is not an issue.
  • Ensure that staff wear lighter clothing for the weather.
  • Open windows instead of relying on air conditioning where possible (make sure that a/c is off if windows are opened).
  • If your premises close down, ensure that all non-essential heating, ventilation, lighting and office equipment are switched off.
  • Prepare a schedule of items needing repair or maintenance before the autumn.
  • Towards the end of the summer, check draught stripping of doors and windows.
 
Autumn

Traditionally, the heating season in many buildings begins on 1 October. In practice, it varies according to the external climate and, particularly in buildings such as offices with large heat gains from equipment or people, it may occur much later.

  • Check timers, and reset where necessary at the end of DST.
  • Do not automatically turn on the heating on 1 October, but only when it is actually required to keep the building warm.
  • Once heating is switched on regularly, check that room temperatures are at the minimum required for comfort and do not overheat.
  • Check that all external doors and windows fit and close properly, and that door closers, where fitted, operate effectively.
  • Have lamps and light fittings cleaned, in preparation for the shorter days
 
Winter

Activate systems only as and when they are made necessary by weather conditions.

  • Ensure that staff wear warm clothing for the weather.
  • Ensure that staff have access to a desk lamp and use it, instead of switching on overhead lights (unless required for health and safety reasons).
  • Make sure that light switches are labelled so that people do not switch on lights unnecessarily, especially when daylight is sufficient.
  • Keep doors and windows shut during the heating season, whilst ensuring adequate ventilation.
  • Ensure that radiators or other heat emitters, are not blocked or obstructed.
  • Try to avoid the use of supplementary electric heaters.
  • Check that security lighting comes on only when it is almost dark.
  • If the buildings are unoccupied in holiday periods, such as Christmas or New Year, make sure that only minimum and safety services operate.
  • Give clear instructions to people on ‘what’ equipment they should switch off over the holidays.
  • Check energy consumption before and after holiday shutdown, and try to identify any unnecessary consumption.
  • Promote a change of energy wasteful habits as part of New Year’s resolutions.
