Energy Efficiency

Improve the energy efficiency of your home by choosing aluminium windows and doors which reduce heating and cooling costs and maximise occupant comfort.

To ensure optimal energy efficiency of your home, attention must be given to both the selection of windows and doors and their placement in the building.

Window Placement

Correct placement of windows and doors allows you to maximise passive design principles to achieve excellent thermal outcomes. Home orientation, insulation, shading, window selection and placement are important considerations in achieving the best possible efficiency and performance for your home.

Window Energy Rating Scheme (WERS)

Bayview Glass aluminium window and door systems are rated by the Window Energy Rating Scheme (WERS). WERS rates the energy impact of windows in housing anywhere in Australia. Energy efficiency is heavily impacted by windows and doors with up to 40% of a home’s heating or cooling being lost or gained through windows.

Improving the energy efficiency of your aluminium windows and doors, reduces your home’s energy costs and Australia’s greenhouse gas emissions. WERS enables windows and doors to be rated and labelled for their annual energy impact on a home, similar to the rating system used on whitegoods.

When windows and doors are rated under WERS they are ranked using a 10 star scale against 17 generic window types. The generic aluminium windows range from very high performance to very low for heating and cooling. A low star rating indicates poor energy efficiency whilst a high star rating indicates higher energy efficiency. A 10 star rating indicates the perfect window system. In Australia, the highest performing windows typically fall between 6 and 7 stars for heating and 4 and 5 stars for cooling. ThermalHEART aluminium windows and doors fall within this range, as do many of our standard high performance aluminium window and door systems.
