Energy efficiency index is a classification method to indicate the energy efficiency of household appliances. According to relevant national standards, China's energy efficiency label divides energy efficiency into five levels.
Energy efficiency standards and energy efficiency labels have been proved to be the most cost-effective way to reduce energy consumption. At the same time, they will bring huge environmental benefits and provide positive returns for consumers.
Hierarchical definition
Grade 1 indicates that the power saving of the product has reached the international advanced level and the energy consumption is the lowest;
Grade 2 indicates that the product is relatively power-saving;
Grade 3 indicates that the product energy efficiency is the average level of China's market;
Grade 4 indicates that the energy efficiency of the product is lower than the market average level;
Grade 5 is the market access index of products. Products lower than the requirements of this grade are not allowed to be produced and sold.
Different grades are represented by different colors and lengths. The shortest is dark green, which represents the "energy saving direction in the next four years", that is, the international advanced level, followed by green, yellow, orange and red. The grade indication color code is arranged according to the emotion represented by the color, in which red represents prohibition, orange and yellow represent warning, and green represents environmental protection and energy saving.
