[Energy-saving Measures Case Study] NSK Ltd. Fukushima Plant
Energy cost for air conditioning reduced by 17.4% in Building No. 2! A case study conducted over multiple years.
We would like to introduce a case where "Dunnest" coating was implemented on the roof of the Fukushima factory of NSK Ltd., a bearing manufacturing company. At this factory located in Shirakawa City, Fukushima Prefecture, multiple painting projects aimed at energy conservation were carried out from 2020 to 2025. The target for the work was the standing seam roof made of Galvalume steel sheets. As a result of the implementation, a 17.4 percent reduction in air conditioning energy costs was achieved in Building 2, where 7,500 square meters of work was completed. This large-scale project has contributed to significant energy-saving effects.
