How do you save energy through your windows?

Have you been struggling with electricity prices of late?

There are two ways to save power. You could tackle the problem at the root and make your home or business more energy-efficient, or you could compare electricity suppliers to see if you can get a better deal.

According to the Department of Industry and Science, heating and cooling are likely to be the biggest contributors to your power bill, and if your home has old windows they certainly won't be helping matters.

Over the last 25 years, advancements in technology mean that modern windows are now up to four times more effective at insulating from the heat and cold than their conventional counterparts, according to the Australian Window Association.

A report from Your Home (a government initiative) shows that up to 40 per cent of a home's heating energy can be lost and 87 per cent of its heat gained through its glass.

Every home has them, so why not consider making them energy-efficient? Here are a just a few tips.

Orientation and size

Whether you're building a new home or making renovations, you should take the opportunity to adjust your windows. For example, north-facing windows receive twice the amount of winter sun than those that are east- and west-facing, according to

Thus, provided you don't live in a tropical climate, you should have your main living areas facing north with expansive windows to take advantage of the winter sun.


While it may cost you a bit in the short term, it will be worth it in the future. There are a range of glazing options depending on your local climate.

Your Home asserts that by having the correct glazing on the windows in your home you can increase noise control, reduce condensation, have better control over the energy flow in and out, prevent the sun from fading your interior furnishings and increase the thermal mass of your home - meaning it will be warmer in winter.

Energy rating

The Australian Window Association recommends choosing the correct window (high in the heating or cooling rating, depending on your climate), which should minimise your use of artificial heating and cooling. This means your home will stay cool in the summer and retain warmth in the winter.
