Hitachi Kokusai Electric Inc.

The production sites of the Company and its Group companies in Japan conduct activities to reduce the energy used at the product manufacturing stage. Since fiscal year 2016, we set a goal of improving Energy Use per Unit to 67 in fiscal year 2018(an 33% improvement compared to fiscal 2005). In fiscal 2017, we achieved the goal of improving Energy Use per Unit to 61(an 39% improvement compared to fiscal 2005).
As efforts regarding facilities in fiscal 2017, we switched from fluorescent lighting to LED lighting and cut off air leakage from a compressed air piping. With regard to operations, in support of the national campaign against global warming promoted by the government, we implemented “Cool Biz” and “Warm Biz” campaigns and continued our efforts in the “Lights-Off Campaign” in all sites.

Note that part of our company was split off into Kokusai Electric Corporation on June 1, 2018. In this article, the thin film process solutions business (business related to semiconductor production equipment) is excluded actual values from the base year and goals.

Switching to LED lighting

Goyo Electronics sequentially adopts an energy-saving equipment, based on the medium- to long-term management plan. In fiscal 2017, we switched from fluorescent lighting to LED lighting in the office and from halogen lighting of the outside signboard to LED lighting of them. We continue to adopt an energy-saving equipment, based on our plan in the future.

Participation in “Lights-Off Campaign“

The Group annually participates each year in the “Light-Off Campaign” organized by the Japanese Ministry of the Environment, switching off lights, such as signboard lights, across its bases in Japan on the summer solstice day as well as on the day of Tanabata, the seventh of July.
We also participated in “Earth Hour,” which was held by the World Wide Fund for Nature (WWF) on March 24, 2018, turning off lights at our sites both within and outside Japan.
