To promote deployment of energy efficiency technologies and application of market incentive mechanism, as well as to encourage manufacturers to invest in research and development of high energy efficiency products, the Bureau of Energy , Ministry of Economic Affairs (BOE) initiated the voluntary “Energy Label” program. Applicants determined to have met the requirements of energy efficiency criteria through the application review process are allowed to affix energy labels on qualified products.

The basis for determining the energy efficiency criteria of energy labeled products is to evaluate the energy performance of products on the market and select the middle to top performers on the efficiency distribution curve. The efficiency criteria are then periodically reviewed and revised to reflect the market conditions. The above measures ensure creditability of energy label in denoting high energy efficiency products.
