Exam & Assignment

The increasing economic and environmental cost associated with energy use and generation, coupled with inefficient operation of energy intensive systems have led to an increase in demand for skilled, experienced energy auditors and system engineers equipped with backgrounds in energy management. This module aims to provide the energy-specific technical, economic, and managerial skills required to conduct energy audits, compile reports, and provide recommendations for energy efficiency best practice for a range of industrial systems.

Learning Outcomes

1. Examine all of the energy streams in a system and develop and benchmark the energy balance between total input and end use and site-specific Energy Performance Indicators (EPIs).
2. Identify energy hotspots throughout the relative processes and systems through the use of on-site instrumentation and benchmark data
3. Conduct comparative analyses of competing systems and apply benchmarking principles for stand-alone energy audits (BER, BS, ISO, NSAI, standards)
4. Apply Life Cycle Cost Analysis (LCCA) methodology of energy systems and provide recommendations for best practices in energy management
5. Generate an organisation’s energy management policy through application of the ISO 50001 Energy Management Standard
