Imagine being able to see what difference using a more energy efficient window will make on energy costs, carbon emissions and energy usage for your home in any climate in Australia.  The efficient glazing tools make this possible.

The website contains online tools to empower the community to make the best choices when purchasing energy efficient windows and doors. With new technologies, increasing energy prices, ever changing regulation requirements regarding the energy efficiency of housing and a carbon tax it is important that all stakeholders in the building market be able to choose products that meet their needs now and into the future. efficientglazing.net encourages participants to understand the benefits of energy efficient design in terms of addressing thermal comfort, rising heating/cooling costs and carbon emissions.

The tools allow informed decisions making about the windows for a house. It is a little known fact that the largest energy consumers in the exterior construction of most houses are the basic type windows and glazed doors. Testing shows that in an average house containing 8% area of glazing in the entire building fabric (windows, walls, floor and roof), as much as 49% of the heat lost during winter and as much as 87% of the heat gained during summer can come through basic type windows. Imagine the expense and carbon emissions that can be saved by reducing the energy that you use to heat and cool your house by using an energy efficient window.

Four tools have been developed. Two basic tools publicly available for general consumers and two membership based and licensed complex tools.

The first of the basic tools is a comparison of generic window types in a small, medium or large house in a selected climate zone highlighting, for example, what difference a double glazed timber window will make compared to a single glazed timber or aluminium window.

The more sophisticated basic tool will do the same but can compare generic windows with actual WERS (Window Energy Rating Scheme) rated windows from the WERS database.

The information received from these two tools includes indicative:

  • Reduced energy usage
  • Reduced carbon emissions
  • $ savings per year

The two complex tools require users to be members of the AWA and WERS or approved Efficient Glazing licensees.

One will allow the extra input of individual energy price data, appliance mix and window pricing providing a more realistic outcome of information compared to the basic tools.

The final tool has all of the same inputs as the three above plus you can input AccuRate energy outcomes on an actual rated home to derive even more precise data.

The information received from these tools includes more accurate:

  • Reduced energy usage
  • Reduced carbon emissions
  • $ savings per year
  • Payback period

The Efficient Glazing tool is an initiative from the Australian Window Association.

The tools have been developed from the findings of the Sustainable Window Alliance (SWA) Project undertaken by the AWA in conjunction with the Australian Glass and Glazing Association (AGGA) and Sustainability Victoria (SV). The Project was aimed at addressing the awareness and use of energy efficient windows and doors in the Australian residential building market, including reaching window and glass industry participants, peak bodies of industries in the residential building sector, end consumers, governments, and regulators.

The AWA will be running training webinars over the next few months so please visit efficientglazing.net for more information.
