Floor and Window Area

Floor Areas

The NatHERS simulation divides the dwelling into specific areas or zones based on whether they would typically be heated and/or cooled by a heating/cooling system.

Conditioned areas are those areas that would normally be heated and/or cooled and cover most areas of a typical dwelling including the living, kitchen, bedrooms and lounge areas.

Unconditioned areas are those areas that typically have no heating/cooling system and include bathrooms, laundries and toilets.

Garage area is the unconditioned garage area.

Window Areas

The visualisation shows the average total window area for the selected state/territory, building class and project type.  The window area is calculated for each star rating group allowing you to see how window areas change as star ratings change.  A dashboard on window orientation is available here.
