Welcome ...

With new technologies, increasing energy prices, ever changing regulation requirements regarding the energy efficiency of housing and the possibility of a carbon tax it is important that all stakeholders in the building market be able to choose products that meet their needs.

This website contains online tools to empower the community to make the best choices when purchasing energy efficient windows and doors.

The tools on this website encourage participants to understand the benefits of energy efficient design in terms of thermal comfort, ongoing heating and cooling costs and carbon emissions.

In testing, based on an average house containing 8% area of glazing in the entire building fabric (windows, walls, floor and roof), as much as 49% of the heat lost during winter and as much as 87% of the heat gained during summer can come from the windows.

Imagine the expense and carbon emissions that can be saved by reducing the energy that you use to heat and cool your house!
