based on the tested energy consumption and information about
the typical use of the appliance in the home. Air conditioners show
the power consumption of the appliance (kW or kWh/h).
The star rating of an appliance is determined from the energy consump-
tion and size of the product. These values are measured under Australian
standards that define test procedures for measuring energy consumption
and minimum energy performance criteria. Appliances must meet these
criteria before they can be granted an energy rating label (Figure 6.13).
Following several years of negotiation between government and
industry, the familiar red and yellow energy rating label was revised
in 2000. Energy efficiency is now measured against a tougher stan-
dard. This change encourages improved technology and more efficient
products, which will save consumers money and will help reduce harm-
ful greenhouse gas emissions. An old energy label was in use in Australia
from 1986 until 2000 and was being reviewed during 2003 to coordinate
and plan future changes across all product groups. The elements under
consideration are deciding whether the green band at the base of the label
should be retained and making the appliance capacity more prominent on
the energy label.
