Energy Tips

General

  • Turn off equipment when not in use
  • Install timers on equipment such as water boiling units and photocopiers
  • Consider energy costs in all purchasing decisions
  • Include energy efficiency in contracts with cleaners and security staff
  • For more information go to the Public Utilities Office link via the Department of Finance website.

Lighting

  • Make use of natural light where possible
  • Only turn lights on when needed
  • Replace existing lamps with energy efficient alternatives (for instance compact fluorescent's use 1/5 the energy of standard globes and last around 8 time longer.
  • Remove lamps from areas with excess levels of light

Heating and Cooling

  • Insulating your home or business will reduce the need for heating and cooling
  • Minimise air-conditioning run times by matching operating times with occupancy hours.
  • A high efficiency split or window/wall air conditioner will use 20% less energy than a similar low efficiency system.
  • Keep windows closed when using refrigerative air-conditioning systems.

Refrigeration

  • Choose a system that best suits your needs
  • For domestic appliances select the one with the most stars
  • Ensure your system is adequately insulated
  • Keep your system well maintained

Compressed Air

  • Don't use excessive pressures
  • Replace compressed air use where possible
  • Remove bends and unused sections where possible
  • Check for leaks on a regular basis

Hot Water and Steam Systems

  • Maintain the system - leaks will increase energy consumption
  • Use high efficiency showerheads and fittings
  • Ensure your system is adequately insulated
  • Maximise condensate return

Office Equipment

  • Turn equipment off when it's not being used and at the end of the day
  • Make energy efficiency a criteria when purchasing new equipment
  • Try to group copying or printing tasks in batches
  • Only print colour when essential

Motors and Drives

  • Make sure your motors are correctly sized for the task. Oversize motors run at lower loads use more energy than a smaller motor at high load.
  • Consider installing variable speed drives on motors with fluctuating loads
  • When purchasing motors always ask for a high efficiency model
  • When considering having a motor rewound, remember that this will reduce the motor efficency
