This paper teaches the practical skills needed to carry out energy analysis in an industrial and commercial setting. Energy analysis is the first step in designing improved energy systems. Students start by developing a toolkit of useful qualitative and quantitative methods for analyzing energy systems from both a financial and a technical point of view. Students then learn to apply energy analysis to real world situations by carrying out professional energy audits of real industrial and commercial sites. Students learn how to obtain and analyze site data, identify areas of possible energy cost savings, and communicate this information to a real client with information on how to successfully implement improvements.
In addition to lectures and tutorials, the paper incorporates site visits to industrial and commercial premises. Past energy audits include local breweries, the Dunedin Art Gallery, water and waste water treatment plants around Dunedin, and coffee and tea factories.
The course consists of 13 lectures, 10 workshop sessions and 2 formal audits. In addition there are a number of guest lectures from industry representatives.
Final exam 30%, Assignments 20%, Audits 50%.

After completing this paper students will be able to:
- Apply theoretical understanding of energy concepts to real-world situations
- State and apply a range of energy-analysis methodologies (including thermodynamic analysis, financial analysis and Life-Cycle Analysis) to a variety of systems
- Use intuition to assess an energy system and identify where to prioritise efforts
- Communicate confidently and effectively in a commercial context both in person and through industry reports
- Carry out an energy audit of a commercial site to the New Zealand/Australia Audit Standard
- Work independently and as part of a group to manage projects and time and to seek and use alternative resources
