Energy Efficiency Audit and Energy Management Programme

Course Description

The main goal is to educate students for an overall understanding of the mechanisms between energy production, energy transportation, energy use, energy policy and the influence it brings to the environment. The activities are based on a theoretical and a practical scheme in order to make the subject as realistic as possible to enable students to work with in industry, business, government, or as a consultant performing energy audits and implementing energy efficiency measures. Programme cover: Energy Efficiency within Energy Supply and Fuel Systems, Electric Energy Management, Process Systems, Building Systems, Energy Efficiency Audit, Technical and Economic Calculations and Case Study.

General Competencies

The program is designed to provide students with the necessary theoretical and practical knowledge in energy management and auditing. Understanding of the basic science of energy, its conversion from one form to another and transfer from one place to another. To be able to predict and monitor the financial effect of changes in practice, or of investment in energy efficient technology, practical calculations involving both energy and money. Students will carry out a number of exercises to enhance comprehension of the theoretical background. This will enable them to carry out energy audits and identify ways of improving efficiency in energy consumption.

Learning Outcomes

  1. explain and identify energy production and consumption in the World and Croatia and role of energy efficiency
  2. apply principles of energy management in industry and organization of energy management programme
  3. assess role and methodology of energy audits
  4. analyze electricity consumption and costs of electricity
  5. recognize most important energy systems in industry (compressed air, boilers, pumps, fans)
  6. analyze energy consumption and energy efficiency in buildings
  7. apply and use measuring instruments for measuring electrical values, temperatures, illumination values, pressure, combustion
  8. apply method of Infrared thermography in energy (infrared thermometers and cameras)

Forms of Teaching

Lectures

Course lectures are organized through 2 study cycles. First cycle consists of 7 weeks of lectures and mid-term exam. Second cycle consists of 6 weeks of lectures and final exam. Lectures are held through total of 15 weeks with weekly load of 2 hours.

Exams

Examination is performed in two parts: in eighth week mid-term exam and in fifteenth week the final exam. Exams are written and consist of multiple choice questions, essay questions and exercises.

Laboratory Work

Laboratory exercises are kept in 7 time slots. In first study cycle 4 and in second cycle 3 laboratory exercises are held. First laboratory exercise is 3 hours long, while all the rest are 2 hours long. First laboratory exercise consists of measuring and instruments introduction. Other exercises consist of one hour of theoretical preparation and calculation exercises and of one hour of performing measurements.

Experimental Exercises
