Text description of Australian climate zones.

The eight climate zones used in Your Home are defined by the Building Code of Australia (BCA). Each climate zone has distinctly different design and construction requirements. Within each main zone are many regional sub-zones determined by local geographic features including wind patterns and height above sea level. The Nationwide House Energy Rating Scheme identifies 69 of these sub-zones, which the BCA addresses and which can be called up by postcode.
