Glass Types - Window Energy Rating Scheme (WERS)
WERS rates the energy impact of residential windows in housing anywhere in Australia.
With up to 40% of a homes energy for cooling or heating being lost or gained
through windows, improving their thermal performance reduces energy costs and
Australia's greenhouse gas emissions.
The aim of the scheme is to help consumers evaluate the relative energy performance
of different types of windows and then make an informed decision suited to their needs.
WERS is a programme implemented by industry and underpinned by the
Australian Window Association's Accreditation Program.
Independent of any one manufacturer, WERS is a fair, rigorous and credible system
for rating the energy performance of windows.
Rated windows will carry a label which certifies that the window has been energy
rated by the Australian Window Association.
The windows cooling and heating performance will be rated separately on a
scale of 0 to 5 stars - the more stars the better.
These ratings indicate the effect the window will have on the energy performance
of the whole house.
In addition, a 5 star energy rated window will provide significant benefits
in noise control and protection from fading.
It is important to remember that the window placement and site orientation
also have an impact on the type of windows required within a house.
