Energy Efficiency Explained
The Role of Windows and Doors
Windows and doors don’t use energy themselves so they’re considered passive products, but by allowing the transfer of energy they severely impact a building’s heating and cooling load.
In fact, regardless of how well a building is insulated, windows are the most vulnerable to energy loss. This means it’s vital to give careful thought to windows and doors during the design and building stages of any project.
How is a window’s energy efficiency measured?
One of the most important ways to reduce a home’s energy consumption is to use the right windows to limit heat gain or loss. There are four main measures for a window’s energy performance, all of which take into account the whole window system (frame, glass, seals, spacers, etc.).
What affects a window's energy efficiency?
There are various design factors that can affect the U Value, SHGC, AI and VT ratings of a window. It’s critical to assess window and glazing options, including their size, frame and glass type, orientation, and fenestration early in the design process to make sure you choose the right window and glazing system.
Choosing The Right Windows
The NCC requires windows to be rated according to the Australian Fenestration Rating Council’s protocols and procedures.
The standardised ratings mean the performance of different glazed systems can be compared like-for-like.
