Cut your energy use and improve working conditions

Energy efficiency in the public sector

Energy efficiency can bring benefits beyond saving money. When it enhances working conditions, it can boost staff morale and increase productivity. And if your organisation has an ethical and eco-friendly charter, reducing your energy consumption is a vital step towards meeting your obligations. The data you receive from a smart meter can show you where you use most energy. They’re the places where you can make potential savings, using our energy efficiency guidance.

Heating and hot water

  • Set your indoor temperature according to the building use – warm environments like laundries or sports facilities require significantly less heating than offices
  • Install timer switches so your heating is only on when your premises are being used
  • Is your water too hot? Every 1°C reduction in water temperature will reduce energy consumption by 1-3%

Ventilation and air conditioning

  • Air conditioning, as opposed to comfort cooling, should only be used in places where humidity control is required, or where fluctuating temperatures can be damaging
  • For optimum productivity, try to keep your building between 20°C and 24°C – turn off the heating above 20°C, and only using air conditioning above 24°C
  • Save energy by installing variable-speed drives in your ventilation fans

Lighting

  • Keep it simple – turn off lights that aren’t in use
  • Switch your switches – daylight sensors, motion detectors and timers can turn lights off automatically
  • When bulbs fail, replace them with CFL or LED products – they use up to 80% less electricity

Office equipment

  • Don’t leave computers and monitors switched on overnight – leaving a single computer and monitor on 24 hours a day would cost you about £45 over a year
  • Install seven-day plug-in timers on communal equipment such as printers and photocopiers to ensure equipment isn’t left on out of hours
  • When replacing IT equipment, choose newer, energy efficient computers and LCD monitors whose screens use up to two-thirds less power
