Can Windows Reduce Your Energy Costs?

Your home is the one place in the world where you want to feel most comfortable. It can be challenging to adjust for weather changes, especially here in New South Wales, where our climate is influenced by multiple factors and varies across the state. 

Did you know that your windows can significantly affect the temperature inside your home – and the kind of energy you consume trying to make yourself comfortable? Windows can make your house too warm and too cold, depending on the time of the year. In our current climate – where we experience weather variations from extreme heat, endless drought, followed by torrential rain and winter frosts, this is an essential factor to consider in your home. 

For the majority of homeowners, around 40% of our annual energy costs relate to heating or cooling our environment. Improving window efficiency can actually save you a considerable amount if you know what to look for.

Reduce your energy costs year round

During summer, when temperatures are at their highest, close to 80% of the heat inside your home can be attributed to your windows. You may also be surprised to learn that these same “inefficient” windows can lose approximately 40% of your home’s heating or cooling energy. Visit to learn more. 

Choosing energy-efficient windows can help you to reduce your energy costs; and we are talking some considerable amounts too! 

Think about your windows, doors and skylights. You can gain and lose heat through:

  • the glass, frame or door via direct conduction;
  • heat radiation into the home from the suns UV rays;
  • heat radiation out of the house through objects, such as people, furniture, and interior walls; and
  • air leakage through and around ageing or incorrectly installed windows, doors and skylights.

Imagine if you could save between 10% and 30% in energy consumption costs per year. This can represent a significant reduction over time on your electricity bill. The less energy we consume, the lower the effect we have individually on the world’s rising temperatures. According to the Australian Academy of Science, a warmer planet – due to greenhouse gas emissions – is one of the many conditions that has played a part in the recent, and devastating, Australian bushfires. 

When it comes to making your home your favourite place, you might think of the items that go in it, rather than considering things like windows. 

So how exactly can I improve my energy use through my windows?

  • Switching to energy-efficient windows is an easy way in which you can level up on your eco-friendly habits. 
  • Choose Aluminium windows. They are an incredibly popular option in this department, thanks to how affordable aluminium is, and how well it ages over time. 
  • Select Viridian Glass. Aluminium frames, combined with Viridian glass, are a winning combination in energy-efficient windows, providing different levels of solar absorption to save you money. 
  • Ensure your windows are installed by professionals so there is no air leakage around the frame and conduction is kept to a minimum.
  • The strength and durability of your window frames also play a factor in keeping energy costs down.
  • Keep drafts at bay. Replacing windows and sealing gaps and cracks can save you up to 25% on your energy bill. If your windows are correctly installed and maintained, you will keep draughts at bay.
  • Use block out curtains or blinds. These can act like insulation devices – so open them up in the winter and close them during the hottest part of the summer day.

How do I choose the right window?

For liveable homes, window selection and placement are integral factors in managing your energy costs. Energy-efficient windows have different panelling layers and special insulation features. 

Your best option, when it comes to choosing windows, is to look at the Window Energy Rating Scheme (WERS) Star Rating. The WERS Scheme conveys information through:

  • Star ratings for heating and cooling
  • Indicative percentage reduction in heating and cooling needs, and 
  • Thermal, solar and optical performance data.

Another reliable way to determine a window’s energy properties and to compare products is to consult the WERS Certified Product List.

Additionally, WERS and the Australian Window and Glass Association have developed a simple guide to help you choose sustainable windows based on your location and climate. For New South Wales climatic conditions, your considerations are a balance of reducing heat flow in summer and gaining solar heat in the winter months. Through energy-efficient choices, you can save approximately 3,000MJ of energy per star – which is the equivalent of $250 per year.
