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)
