Why efficient glazing?

The Building Code of Australia (BCA) defines glazing as :

Volume 1 – Section J, A1.1
– “Means a transparent or translucent element and its supporting frame located in the envelope and includes a window other than a roof light”
Volume 2 – Section, Note 3
– “by referring to glazing elements this requires total U-values and Solar Heat Gains to be assed for the combined effect of glass and frames, as specified by the Australian Fenestration Rating Council (AFRC)”

This website has been designed to highlight the effects of “glazing” on the thermal; performance of housing. With up to 40% of heat loss and 87% of heat gain in housing being transferred through windows this website aims to allow the most thermally efficient choice of “glazing” for your house.

The efficient glazing tools allow you to make informed decisions about the windows you are purchasing for your house.

simple window comparison tool
This free online tool allows consumers to compare several different types of window to understand exactly how much you could save on your annual energy bills and how this can reduce Australia's carbon emissions.

advanced window comparison tool
This online tool allows members to compare custom WERS accredited windows for variables including GHG emission abatement, payback periods, gas/electricity usage mixes, variable energy prices and much more.

accurate input tool
This online tool allows members to compare runs of accurate assessment outcomes for variables including heating/cooling cost reduction, GHG emission abatement, payback periods, gas to electricity usage mixes, variable energy prices and much more.

The Efficient Glazing Tool is an initiative from the Australian Window Association (AWA) developed from the findings of the Sustainable Window Alliance (SWA) Project.

The SWA project was undertaken by the AWA in conjunction with AGGA and Sustainability Victoria. 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.
