This could be a living room, bedroom, or anywhere else you feel comfortable in. The aim is for all household members to use this room on hot days. Focus on cooling down this room rather than your whole house.
  • Switch to using a fan rather than the air conditioning: a ceiling fan or portable fan can be used. To create extra cool air, place a shallow bowl of ice in front of your fan 
  • Remove floor rugs to expose cooler flooring 
  • If you do use air conditioning, set your aircon to 24-27 degrees to reduce running costs and regularly clean the system for increased efficiency 
  • Use your windows wisely:
  • Shade your windows - Block out the sun with indoor blinds and curtains, and outdoor blinds and window coverings. Stopping the sun will cool down your home 
  • Close the house up and close curtains during the heat to stop cool air from escaping
  • Open windows and doors during the cooler parts of the day to let in cool air, fix fly screens so your home can stay bug-free while ventilated 

 

Appliances:

Planting for house cooling:

  • Plant trees and plants, or use pot plants, that provide shade to windows. If you want more natural light during the cooler months, use plants that shed their leaves during autumn and winter like jacaranda, ash, birch, maple and robinia 

 

Cool down your body temperature:

  • Use a cool, damp cloth on your forehead or body for added cooling
  • Take a cold shower to cool down your whole body 
  • Wearing natural, breathable fabrics such as cotton, linen and bamboo allows your body to regulate body temperature 

 

Sleeping cool:

  • Bed sheets Sustainability Images for Website 20253.jpg Use natural fibre bedding, such as 100% cotton or linen sheets. These are lightweight breathable fabrics that will help keep you cool
  • Use your microwavable heat packs as cooling packs. Place these in the freezer to cool down 
  • For children, place their favourite soft toys in the freezer to cool down
  • Open windows to allow cool air to circulate into your home during the night, and use fly screens to stay bug-free 

 

Home upgrades to keep cool:

  • Provide a cool place for your pet to hang out, like a cooling mat, damp towel, tiles, an ice brick wrapped in a towel, or a water bath
