Japan Amends Criteria for Energy Consumption Performance of Computers

On March 29, 2019, the Japanese Ministry of Economy, Trade and Industry (METI) issued an amendment to the Notice on Evaluation Criteria for Energy Consumption Performance of Computers. The document introduces a new energy standard (Public Notice of METI No. 69).

This public notice stipulates new energy conservation standards for server-type and client-type electronic computers and sets the target fiscal years when manufacturers should achieve the defined energy-saving performance of these two types. The deadlines are set as FY2021 and FY2022, respectively.

METI proposed a new energy efficiency standard for computers in order to promote rationalization of energy use pertaining to computers in Japan and disseminate energy efficient computers. This will help to cope with the recent increase of energy consumption, global warming problem, and so forth.

The existing FY2011 standards defined energy consumption efficiency rates derived from calculation based on the electricity consumption and performance of CPUs (composite theoretical performance of CPUs). Currently, components other than CPUs, e.g., display and storage, consume a large portion of the total electricity. Taking this into account, the new standards introduce a calculation method of energy consumption efficiency rates by taking into account these additional elements.

METI will promote further energy conservation of electronic computers by setting the energy conservation standards based on energy consumption efficiency rates taking into account changing capabilities and environments.

Shift of the indications between the conventional and new standards is as follows:

  • Server-type electronic computers

  • Client-type electronic computers

As for the enforcement of the new standards for revised indications, METI sets a one-year shift period until March 31, 2020. This means that manufacturers are permitted to continue the conventional indications up until that date.

Manufacturers, importers or sellers must properly indicate energy consumption efficiency of these products in catalogs or documents which are provided to consumers.

This Notice entered into force on April 1, 2019.
