Energy efficiency theory


SWindowDiagram10

Energy Efficiency has become a major consideration when building a new home or planning an extension to an existing home.


An Energy Efficient home exists in a complimentary way to the climate that surrounds it, thus minimising the effects of extreme temperatures. To do this the house uses the sun for heating when it is cool, but on hot days minimises the heat taken in. On these warmer days, window ventilation should take advantage of any cooling breezes or drop in outside temperature. To ensure that the controlled interior climate remains stable, the building materials utilised need to ensure minimum heat transfer.

The type of window and glass combination used has a big impact on the overall Energy Effectiveness of your home.
