Other measures

  • Air conditioning – air conditioning is a refrigeration process. So the principles we’ve talked about here all apply just the same –setting optimum temperature, choosing the most efficient hardware and system maintenance is important. Also remember that the cheapest way to keep people in a building cool is to ventilate and lift air speeds using fans.
  • Choosing office equipment – before choosing your computer and screen, check their efficiency rating as this will have a long term influence on running costs. Newer processors and screens run more efficiently than old ones, so as well as checking speed and performance, look out for energy efficiency too.
  • Energy saver powerdown for office equipment – remember to shut systems down when you are not using them. Just because your screen is on standby doesn’t mean it’s not using electricity. A clever little plug in device can help by shutting the power off to all connected items - like screens, printers and speakers - when the main computer is switched off.
  • Measure and compare – one thing that’s common to improving the efficiency of all equipment is to know what energy it uses and what savings can be made if you use it differently. Key to this is monitoring use and comparing it with alternative equipment or ways of operating. You can use various types of metering, either logging your energy use automatically or simply taking manual readings. It really does help in understanding how you use energy and how you can save money.
