The Ministry of Economy, Trade and Industry discussed the Label Display Program for Retailers2 under the Act on Rationalizing Energy Use in the Council3 on the program, and revised the multiple-scale scoring system and uniform energy saving label designs in November 2020 and August 2021. At the time, it was decided that the Label Display Program for Retailers for air conditioners—for which energy efficiency standards were still under consideration—would be revised based on the outcomes of the council's deliberations.
Now, with the formulation of new energy efficiency standards for air conditioners in May 2022,4 METI has gathered comments from the public regarding the revisions to the Label Display Program for Retailers, and partially revised and promulgated a public notice to stipulate specific items to be displayed in the Label Display Program for Retailers for home-use air conditioners (non-ducted wall-hung type) today.
2. Outline of the revisions to the Label Display Program for Retailers
(1) Revision of the design of the uniform energy saving label for air conditioners and new establishment of mini-labels, etc.
The uniform energy saving label for air conditioners has been redesigned to reduce repeated information, make it simpler and easier to understand, and to make the color scheme more visible to more people. In addition, in accordance with the new standards for air conditioners (target year: FY2027) which have new categories by specification (non-cold regions / cold regions), a new label for those for cold regions5 has been established. (See Figure 1)
Furthermore, new mini-labels have been established to ensure that retailers can provide energy-efficiency information even in limited spaces, such as on the products and online shop pages. (See Figure 2)
(2) Revision of the multiple-scale scoring system for air conditioners
The current five-star scoring system has been changed to a rating scale from 1.0 to 5.0 with increments of 0.1.
Moreover, while the number of stars is currently determined based on the achievement rate on the energy efficiency standards, 1 to 5 stars including half stars will be given according to the rating score calculated on the basis of the energy consumption efficiency (APF in case of air conditioners) after the revision.
