How can I save power during summer?

No cost

  • Keep windows, curtains and blinds closed during the day to stop the summer sun from getting into the house
  • At night time, open windows and blinds to let hot air out and cool air in. If you have west facing windows, open them in the late afternoon to let the sea breeze in
  • At the start of summer, clean the filters in your air conditioner. This means your air conditioner won’t have to work as hard when cooling your house
  • Before turning on the air conditioner, try using a fan, you could save up to $200 a year
  • Keep your air conditioner setting at 24 degrees – every degree lower you set your air conditioner can significantly affect running costs during the summer
  • Keep the doors to the room you’re trying to cool closed when using the air conditioner. This prevents cool air from escaping and the air conditioner isn’t cooling rooms you’re not using

 Low cost

  • Put some shade cloth over your east and west facing windows. This will stop some of the sun before it hits your windows and heating up your house
  • Plant deciduous trees/ bushes on the western and eastern sides of your house. These will block summer sun but let winter sun through

 Higher cost

  • Install roof insulation. This will prevent heat entering the house but also the cool air from your air conditioner escaping
  • Install 'whirly birds' or roof ventilators on your roof. This will remove hot air from the roof cavity, helping keep the house cool
