Description Whole Life Cycle Analysis, or sometimes referred in literature to as Whole Life Cycle Cost, is an analysis of the impact, systems, processes, or services have on environmental, economic and social domains from cradle to grave. The aim of this module is to introduce the student to the concept of life cycle thinking, and to equip the student with the appropriate skills and understanding to conduct Whole Life Cycle Costing (WLCC) of engineering systems, processes, and services. Environmental Life Cycle Assessment (E-LCA), economic Life Cycle Cost Analysis (LCCA), and Social Life Cycle Assessment (S-LCA) represent the three pillars of WLCC and encapsulate the relevant aspects of environmental, economic, and social impacts of system investment and operation. This module also provides an understanding of the responsibilities of the engineering profession towards people and the environment. | |||||||||||||||||||||||||||||||||||||
|
Learning Outcomes 1. Assess the environmental impact of engineering systems, products, and services within the framework of the LCA methodology as per the ISO 14040 series of standards 2. Select appropriate Key Performance Indicators (KPIs) for benchmarking applications in WLCC 3. Develop bespoke system models with LCA software for analysis and optimization of a system’s environmental profile 4. Evaluate economic ‘hotspots’ in a system through LCCA and propose recommendations on change actions 5. Interpret qualitative S-LCA data and evaluate the associated location-specific social standards as they relate to a system supply chain and network 6. Compile comparative WLCC analyses of competing systems and products for relevant stakeholders | |||||||||||||||||||||||||||||||||||||
