While summer is a great time for heading to the beach and enjoying the sunshine, it can also make temperatures inside your home rise. Air conditioning helps cool things down, but what if you could avoid your house becoming too hot in the first place?

Your home's front façade is the first thing people will see when they drive down the street, so while it’s important to get the aesthetic right - it’s also important to note that picking the right colours for the exterior of your home could help reduce your energy bills.

Here are some tips to help you decide the best exterior colour palette to make sure your home is as comfortable and energy efficient as possible.


Exterior Colours

With Australia’s warm weather, it’s a smart move to be energy conscious about your home, so light coloured facades are ideal to help stay cooler in summer by reflecting heat. In contrast, darker colours can absorb up to 90% of radiant energy from the sun, which isn’t so fun in summer…

With this in mind, the best colours for exterior walls are light coloured neutrals – think white, light greys and beiges. Not only will these light hues keep your house cooler in summer, they usually have broad appeal and date less quickly than darker coloured homes.

Roof Colours

The roof is another major element which will affect the overall visual appeal of your home and can play a big part in saving energy costs.

Similar to exterior colours, light to medium roof colours are most suitable for houses in warmer climates. Recent studies have shown that white to mid-grey roofs can have approximately 30% lower heat gain than a dark roof as they absorb less of the sun’s heat.

Accent Colours

If taking our advice and going with neutral coloured exterior walls and roofs has left you feeling flat, darker coloured accents might be your place to shine – think gutters, downpipes, window frames or small feature walls.

Façade accents are a great way to add personality and character to your new home and can usually be easily repainted to suit changing tastes in years to come.

By taking these steps to keep the heat out, you may be able to lower your energy bills and stay more comfortable throughout the year. It’s always worth remembering that your location should be a major factor in your home’s exterior design, these tips are intended for warm climates and may not be appropriate for colder climates where dark colours may be worth considering.
