Energy labelling
energy label

Energy labelling is now common in most countries around the world and as its name indicates, describes the energy consumption or energy savings potential of a product and ranks one or more criteria in terms of performance.
The introduction of labelling has had numerous beneficial effects which include –


  • establishing a dialogue between buyer and seller
  • comparing the life time cost of various models which can be defined as the initial cost plus the running cost of energy over its lifetime; other consumables can also be costed such as that of water for washing appliances; the cheapest models may not have the lowest running costs
  • introduction of minimum efficiency standards for energy consuming or energy saving products; this has resulted in the least efficient products being withdrawn from the mark

The illustrated label is for a washing machine and indicates not only the amount of energy and water it uses, but also rates its washing capability.

Energy labelling has encouraged manufacturers to improve the efficiency of their appliances because the incremental cost is often small and consumers are becoming more aware of the cost of energy and its likely impact on the environment The greatest increase in efficiency has been in lighting where incandescent bulbs have been replaced by compact fluorescent and LED bulbs with a corresponding increase in efficiency increase from 10% to over 90%.

Energy efficiency of buildings have also been labelled and these labels are illustrated below and need to be displayed or shown for all buildings when rented or sold.
