Timing is everything in improving energy efficiency. Anytime an industrial facility makes capital improvements there is an opportunity to achieve energy efficiency while improving the project’s Return on Investment. For large warehouses, manufacturing facilities, and light industrial facilities, lighting accounts for approximately 10% to 15% of their operating and maintenance costs. Through efficient design with high-performance lighting technologies, and the use of automated controls, many facilities can reduce energy and maintenance costs for lighting by 40% to 60% or more.
