Energy-Saving Activities

The NGK Group has been actively promoting energy-saving activities in relation to general-purpose equipment, such as lighting, air conditioners, boilers, and compressors. The headquarters plays a central role in this in terms of sharing know-how among different manufacturing locations, thereby achieving more efficient activities.
Whenever our buildings are built or altered, we ensure that large-scale energy-saving measures and ZEB (zero energy building) principles are incorporated.

(1) Headquarters Supporting Energy-Saving Activities at Overseas Manufacturing Sites

The headquarters Engineering Department has, over the years, sent personnel to overseas manufacturing sites to perform energy audits and, as necessary, help local staff develop and carry out effective energy-saving measures using the know-how gained from practices in Japan.
These efforts have produced solid results at overseas companies, including NGK Ceramics Polska.

(2) Creating and Distributing a Printed Version of the Energy-Saving Brochure and Guidelines

We have created a printed version (Japanese, English) of our energy-saving guidelines and brochure of best practices, both of which were previously available only in digital formats. Copies have been distributed to each manufacturing site in and outside of Japan to be kept handy at worksites for easy reference. This is expected to help enhance activities to reduce CO2 emissions.

(3) Efforts to Conserve Energy within Buildings

Concept drawing for the administration/welfare wing in Mizuho
(scheduled for completion in December 2019)

Whenever there is the opportunity to build or renovate a building, we actively endeavor to utilize high-efficiency equipment and introduce renewable energy, and carefully consider each location so as to be able to effectively utilize any natural advantages, such as low-temperature waste heat from adjacent factories and natural ventilation/lighting, to achieve significant energy savings. The administration/welfare wing, which is currently under construction in Mizuho, Nagoya, is going to be a zero energy building (ZEB) that achieves a reduction in CO2 emissions of 54% from the official standard.
Our initiative to use pioneering CO2 reduction technology for this building was recognized by the Japanese government, and the construction project was adopted as a Leading Sustainable Building Project (CO2 Reduction) by the Ministry of Land, Infrastructure, Transport and Tourism.

We have many more construction/renovation projects lined up as part of our plans to reorganize corporate structure and update old buildings, all of which will include energy saving and ZEB measures.
