Windows prove critical to energy efficiency

That better performing windows significantly reduce energy consumption for home owners has been proven by an independent study.

The study, conducted by the Sustainable Windows Alliance, has concluded that typical Australian homes can increase their energy efficiency by two to 2.5 stars by changing from the worst-performing to the best-performing windows. Applying passive solar design principles can further improve a home’s efficiency by up to one star.

The Sustainable Windows Alliance is a joint initiative of the Australian Glass and Glazing Association and the Australian Window Association, in partnership with Sustainability Victoria.
