Establishing baseline electrical energy consumption in wood processing sawmills for lean energy initiatives: A model based on energy analysis and diagnostics

This research focuses on the benchmarking of electrical energy use at sawmills. Lean energy (a programmatic concept similar to lean manufacturing) is facilitated by this research, which furthers the understanding of energy intensity at sawmills, leading to reductions in operating costs and increases in profitability. A user-friendly interactive model, Baseline Electrical Energy Consumption in Wood Processing Sawmills (BEECWPS), was developed to enable the user to create an energy profile based on sawmill process dynamics and to provide information about product, process, and system parameters. These parameters were gathered by visiting six sawmill facilities in West Virginia. A detailed methodology was developed to collect the field data and determine an energy intensity. The proposed model has the capability of developing the energy benchmark for a facility under consideration, upon successful submission of required data, and will aid lean energy initiatives within the organization. Manufacturing engineers can use BEECWPS to effectively identify the effect of product, process, and system parameters on energy consumption and intensity to revise production system strategies.
