Department of Energy Technology Engineering

The student will acquire knowledge, to assess the overall and individual energy consumption in any energy system (simple or complicated, with one or more energy sources) and to be able to interpret any over-consumption within it, to evaluate and propose measures to save energy and reduce the energy costs, to specify system for continuous monitoring of energy consumption, for setting targets and immediately identify and address overconsumption, ensuring high efficiency in the studied energy system both in nominal operating conditions and, especially, in real conditions over time.

Course Description

The energy issue - Energy Policy - History and forecasts - Importance of Energy Management. Energy consumption in various sectors. Specific energy consumption - Estimation, adjustment and correction of energy indexes. Analysis of a multi-energy system, partition in individual energy accountable centers. Processing energy data to identify base load, variable loads and their correlations with parameters of the energy system. Approaches to energy tracing, monitoring and targeting energy consumption. The energy audits. Description, methods, targets. Problems and Conditions for a reliable metering program to implement energy inspection and audit. Energy management in buildings. Analysis of consumption. The method of heating degree-days for approximate energy calculations. Building energy management systems. Energy management in industry. Strategies for energy saving and environmental protection. Modern methods and energy-saving technologies, and early techno-economic evaluation. Exergetic efficiency and exergy analyses. Pinch technology and application examples. Relevant legislation (for energy audits, energy officer, etc.).

Expected Course Outcome

Upon successful completion of this course the student will be able to:

Conceiving program monitoring energy consumption and proper analysis, for energy purposes and early diagnosis of any problems
Propose energy saving measures and evaluate then from the technical and economic points of view.
To perform energy audits (in buildings, industry).
