Summer is one of the most exciting seasons of the year, with sunshine, BBQs, trips to the beach and festive celebrations filling our calendars. For many households, rising temperatures brings with it higher energy consumption, especially when air-con is relied on to keep the house at a comfortable temperature. With higher energy consumption comes skyrocketing energy bills, so how can you beat the heat without breaking the bank?  

We’ve listed some of the ways you can keep your house cool throughout the summer months.  


Insulation is necessary to save on energy consumption as it blocks out intense heat, keeping your house cool throughout summer. To reduce radiant heat gain, insulation should be installed under the roofing material, corners of ceiling walls and floors.  

Of course, it’s important for you to choose the right insulation materials. The Australian Government website for energy efficient homes, Your Home, advises homeowners to check the R-value of your insulation, which measures resistance to heat flow. This means that the higher the R-value, the higher the level of insulation. Insulation materials that meet the Australian Standard have a clearly marked R-value on the packaging.  

Use Split-System Air Conditioner  

Made up of an outdoor compressor unit and an indoor unit connected by pipes, split-system air conditioners are ideal for cooling one or more rooms, and open-plan areas. Choose a split system that not only monitors the temperature within your home, but also purifies the air that circulates inside it.  

Consider Mechanical Cooling Devices 

According to the Your Home website, fans are an effective first choice when it comes to mechanical cooling. If your home already has good insulation and doesn’t require intense cooling, you can install ceiling or standing fans for a cost-effective means of cooling. They can also help to circulate the air within your home, which can enhance comfort and reduce the temperature by 3°C. Aside from the fact that they are the most cost-effective form of cooling, fans also have the lowest greenhouse impact too.   

Double Glaze Your Windows 

According to Your Home, up to 87% of heat gained in your home comes from the windows. That’s why it’s highly recommended to invest in double glazing, since it reduces the flow of incoming and outgoing heat. Aside from making your home more comfortable during the summer and lowering energy costs, it’s also an added security since double glazed windows are harder to break.                      

Practice the Art of Shading  

Internal blinds and curtains help to block out sunlight, which contributes largely to heat gain during summer. Ensure you install good-quality blinds on your east and west-facing windows to protect your home from the sun’s most intense rays. You can also reinforce these with external shading through bushes, eaves, awnings and shutters.
