Basic Stance of Energy AuditImprove operation ⇒ Retrofit equipment ⇒

Renewal facility & equipment

Energy conservation: “3K” of energy conservation

What is energy conservation?

⇒ Reduce energy consumption + Raise efficiency

◆1K:Improve operation → No investment

(Improve=“Kaizen” in Japanese)

◆2K:Retrofit equipment → Low to middle investment

(Retrofit=“Kaishu” in Japanese)

◆3K:Renewal facility & equipment → High investment

(Renewal=“Koushin” in Japanese)
