Design takeaway

How to apply

When designing or analyzing manufacturing processes, utilize parameterized models to predict energy consumption and gather data for LCA. Focus on understanding the contribution of both constant and variable energy consumers within the machinery.

Project actions

01When researching energy consumption for your design project, consider if a parameterized model could simplify data collection.
02Investigate the 'power key values' of machinery to understand how energy is consumed.

Method & Evidence

AimHow can parameterized modeling of machining processes improve the efficiency of data acquisition for Life Cycle Inventory (LCI) datasets and subsequent Life Cycle Assessment (LCA)?

MethodModel Development and Case Study Application

ProcedureThe Extended Energy Modeling Approach (EEMA) was developed to calculate total energy demand based on power key values (average power consumption of constant and variable units across different operating states). Methodological requirements for LCA-compliant datasets were analyzed. EEMA was then applied to a case study of a turning machine to assess its effectiveness.
