This paper presents an on-going effort at NIST to model the energy information in assembly and logistics processes as a part of a larger sustainability improvement goal. Energy information comprises energy input, baseline energy consumption, and energy performance. An information model in this paper is developed for enabling integration of energy information in assembly and logistics processes. Based on this information model, industry will be able to share energy-related data on the overall plant level which is traceable to individual processes, equipment, and suppliers. This will enable manufacturers to identify energy saving opportunities in their assembly processes and supply chains.
