Ceiling fans can often supply adequate cooling for acclimatised residents in all Australian climates. They circulate air but do not reduce temperature or humidity. Typically, the air flow created by a fan provides a similar improvement to comfort as reducing the temperature by around 3°C.
In tropical and sub-tropical climate zones, the use of ceiling fans is common and in some jurisdictions additional star rating credits are available if ceiling fans are installed in particular zones. The charts below show the distribution of number of ceiling fans installed in a dwelling by NCC climate zone and also by State and Territory.
