Defines terms used to measure the energy efficiency and specifies the methods for calculation of all quantities which appear on the energy efficiency (i.e. 'star rating') label. It specifies the minimum performance criteria required for registration of a model in Australia and sets out requirements for the printing, placement and validation of the energy label. Appendices include example calculations for energy labelling and an approved registration application format. Calculations require data measured according to AS/NZS 2442.1, energy consumption and performance.
