Australia is a hot country. There are no two ways about it. At some point in the year—whether you’re in the humid north, the dry west, or even the comparatively temperate south—you’ll need some level of cooling in your home to stay comfortable.

While air-conditioning is often the go-to solution, relying on it too much can lead to high energy bills and an increased carbon footprint. Fortunately, there are a number of practical ways to keep your home cool without overusing your air-conditioner—and without sacrificing comfort.

Let’s explore how you can stay cool naturally and efficiently, even during the hottest months.

 


 

1. Using Windows and Doors Strategically

How you open and close your windows and doors throughout the day can significantly impact your indoor temperature.
 

Nighttime Ventilation

Open windows and doors at night to let cooler air in. Be sure to open clear passageways for air to flow through your main living areas. If insects are a concern, install fly screens to let the cool air in while keeping bugs out.

Daytime Heat Control

During the day, keep windows closed and cover them with thick, block-out curtains to prevent heat from entering. Adding awnings or external shading to your windows can also block direct sunlight, further cooling your home.

 

By carefully managing the airflow in and out of your home, you can reduce the need for air-conditioning while still keeping your living space comfortable.

 


 

2. Segment Your Home

Cooling your entire home can be a huge energy drain. Instead of cooling unused rooms, focus on the areas you are actively using.
 

Close Off Unused Rooms

If you can, separate the main living areas from bedrooms and other less-used rooms. This will help to keep cool air contained where you need it most, reducing the amount of cooling needed in the rest of the house. Even closing doors or installing curtains can help make a big difference in keeping your home cooler and reducing energy consumption.

By zoning your home and cooling only the rooms you’re in, you can significantly cut back on your energy use.

 


 

3. Use Ceiling Fans to Complement Air-Conditioning

Ceiling fans are an affordable and energy-efficient way to improve indoor comfort. While they don’t lower the air temperature, they can create a cooling effect by circulating the air.
 

Fan and AC Combo

Run your air-conditioner for an hour to cool a room, then switch to a ceiling fan to circulate the cool air. Alternating between the two can help maintain a comfortable temperature without overworking your AC.

Because ceiling fans use a fraction of the power needed by air-conditioners, they’re an ideal way to reduce your overall energy consumption while staying cool for longer.

 


 

4. Draft Proofing: Seal Out the Heat

Sealing drafts is a simple yet effective way to keep your home cooler during the summer. Even small gaps in windows, doors, or walls can let hot air in and cool air out, making your air-conditioning less effective.

 

Check for Gaps

Look for gaps under doors, around window frames, and in the floors or walls. Sealing these gaps with weather stripping or caulking can help maintain your home’s temperature and prevent energy loss.

Install High-Quality Windows and Doors

Installing energy-efficient windows and doors will help limit drafts and improve your home’s overall insulation, keeping it cooler during the day and reducing your reliance on cooling systems.

 

By ensuring your home is well-sealed, you can retain the cool air inside and avoid unnecessary cooling costs.

 


 

5. Double-Glazed Windows: The Ultimate Cooling Solution

One of the best ways to keep your home cool without relying on air-conditioning is to install double-glazed windows. These windows are made from two panes of glass sealed together with a gap between them, typically filled with air or gas (such as Argon). This gap acts as an insulation barrier that significantly reduces heat transfer, helping to keep your home cooler during summer.
 

Improved Insulation

Double glazing can boost your home’s overall insulation by up to 50%, keeping the heat out during the summer and the warmth in during winter.

Energy Savings

Reduced heat gain means you can rely less on air-conditioning, saving money on cooling costs and lowering your carbon footprint.

Noise Reduction

Double glazing also helps reduce external noise, creating a more peaceful indoor environment.
 
Installing double-glazed windows is one of the best investments you can make for energy efficiency and comfort in your home.
