Life cycle energy optimisation for conceptual vehicle design (LEnOp)

Hamza Bouchouireb, Merle-Henrikje Jank, Ciarán O'Reilly, Peter Göransson, Rupert Baumgartner and José Potting

This project explores how the life cycle energy optimisation methodology may be applied to concepts for balancing specific cross-functional requirements. The methodology integrates a life cycle environmental proxy within a multi-disciplinary design optimisation framework, which can be used to directly balance environmental considerations with conflicting transport functions. The proxy used is life cycle energy (LCE) taken as the total energy requirement of a product over its entire life cycle. This should lead to a more globally optimal solution. The goal of the optimisation is to minimise the life-cycle energy while fulfilling other functional requirements chosen at different levels of complexity.
