Focus Industry ENERGY REBATES | 01/09 | Project #1: Lighting Optimization BY THOMAS MORT, CEM Reducing energy costs and pollution emissions involves many areas within an industrial facility. My studies have found seven key (or common) areas where low-cost practical projects can be implemented. Combined, these projects provide savings exceeding 10% of the annual energy spend of a typical industrial facility — with an average payback of less than one year. This month’s article will focus on Lighting. Optimizing the lighting system can help reduce annual energy costs by approximately 2%. Lighting is a popular energy saving project and many facilities have already begun projects in this area. Often some key points are overlooked resulting in project costs being higher than necessary. Understanding the correct requirements can significantly reduce capital costs. CO2 O 7 Key Sustainability Projects 1. Lighting 2. Demand Control Lighting Energy Costs and Project Objectives The factory used for this example is a facility with 149,000 sq. ft. including manufacturing floor, warehouse and office areas. The factory produces small metal and plastic injection-molded components. The annual energy spend for the facility is $1,483,000. There are 125 Metal Halide light fixtures and 355 fluorescent light fixtures. Lighting energy costs are 4.5% of the total energy spend or $67,200 per year. The objective of a lighting optimization project is to: REDUCE ENERGY USAGE OF THE LIGHTING SYSTEMS BY PROVIDING THE CORRECT AMOUNT OF LIGHT AT THE CORRECT TIME WITH EFFICIENT FIXTURES. 3. HVAC 4.
