The Window Energy Rating Scheme (WERS)
accurately shows consumers the relative energy performance of different types of windows,
helping them make an informed choice.

WERS is a program implemented and endorsed by the Australian Greenhouse office. It is independent of any one manufacturer and is acknowledged as an accurate system for rating the energy performance of all types of windows
and glass doors.

The program is managed jointly by the Australian Building Codes Board and the Australian Greenhouse Office under the National Greenhouse Strategy. It is a clear example of cooperation between industry and government to reduce the energy consumption and greenhouse gas emissions of the building sector. Energy efficient homes will deliver cost savings to consumers through reduced electricity and gas bills.
