This paper presents an on-going effort at NIST to model the energy performance in assembly and supply chain processes as a part of a larger sus-tainability improvement goal. Energy performance modeling comprises two dis-tinct metrics like energy consumption and energy efficiency. A new approach to predict these metrics through computation models is proposed in this paper. Theoretical minimum energy for the above mentioned processes are used to calculate energy efficiencies rather than the historical energy baseline data in our approach. In addition, an information model is presented in this paper to serve as a guide to industry to aggregate energy across processes under study. Based on this information model, industry will be able to assess energy con-sumption and efficiencies on the overall plant level yet traceable to individual processes, equipment and suppliers. This enables manufacturers to identify en-ergy saving opportunities in their assembly processes and supply chains.
