The Window Energy Rating Scheme enables windows to be rated and labelled for their annual energy impact on a whole house, in any climate of Australia.
To participate in WERS, window makers must obtain energy ratings for their products from a rating organisation that is accredited by the WERS Management Committee.
WERS is independent of any one manufacturer and acts as a fair, rigorous and credible system for testing performance claims. WERS-rated windows must meet all relevant Australian standards. The scheme forms part of the quality assurance that professional manufacturers offer their customers.
WERS ratings are designed for input into NatHERS, Australia’s Nationwide House Energy Rating Software. Similarly, the FirstRate house energy rating software from the Sustainable Energy Authority of Victoria will accept data for ‘real’ windows. This enables designers to compare the results of different windows during a rating before final selection is made.
