"Energy-efficient appliances" are energy saving appliances. From 9 November 2009, the Hong Kong Government has put in effect the "Mandatory Energy Efficiency Labelling Ordinance". Three major types of domestic appliances (air-conditioners, refrigerators and compact fluorescent lamps) must be classified under the "Mandatory Energy Efficiency Labelling Scheme" (EEL) which informs consumers the energy efficiency level of a particular electrical appliance with an "energy label".
The EEL ranking is divided, based on the relative energy-efficiency performance of domestic electrical appliances, into 5 grades, with Grade 1 being the most efficient, and Grade 3 the general average among the same category of products. Here are examples of EEL Grades 1 to 3:
Grading Level of Energy Label
(Grade1 VS. Grade3)
Electric storage water heater (standby)
Electric clothes dryer
Compact fluorescent lamp
A "Recognition Type" energy label however does not provide information about energy consumption. It only certifies that the labelled product has met the minimum energy efficiency requirements stipulated by the EEL scheme.
