This course aims at providing an introduction to and overview of the broad field of energy technology. A condensed cross-section of essential engineering concepts/principles from the domain of thermodynamics and heat transfer is provided, including a review of the concepts of energy and power, energy conversion, energy efficiency, reversible and irreversible processes, and basic thermodynamic cycles. An overview of global energy resources is given, leading to a historic review of human energy use and power generation. Society's energy demands and the pertinent energy flows are analysed from the perspective of different sectors, including industry, households, transport, agriculture, as well as commercial and public sectors - in Croatian and international perspective. The significance of power generation and energy utilization is analysed as relevant to GDP, living standard, associated socio-economic issues and development. The significance of measurements in energy technology is described and temperature and pressure measurement basics are given. The importance of energy efficiency and conservation within the context of future energy supply is dealt with from a life-cycle and environmental perspective (with regard to emission control/reduction, global warming, international environmental laws/regulations and goals, etc.). Future energy systems and energy use scenarios are discussed, with a focus on promoting the use of energy efficient technologies and renewable energy resources and technologies. Relevant political and socio-economic issues are discussed.

The objective of this course is to discuss energy-efficient and environmentally compatible power generation systems. The introductory section includes an overview of heat and power technologies, followed by an analysis of the most significant heat and power generation technologies, including those based on steam and gas turbine cycles, as well as combined steam and gas cycles. The course also provides a general overview of non-combustion-based (renewable) power generation technologies, including those based on the exploitation of wind, hydro, solar and geothermal resources. A more detailed course on renewable energy technologies is provided in the course Renewable Energy Technology and Biomass, Wind and Hydro Technology. The second portion of the course deals with reactor technology and nuclear power safety, focusing on the properties and performance of boiling and pressurized water reactors. This section deals with the choice of materials, fuel cycles, control systems, and particularly, environmental and safety-related issues. The course includes study visits to relevant industries and plants, as well as laboratory exercises.

The objective of this course is to discuss the codes of sustainable practice in energy utilization in built environment. A broad range of technologies used for space conditioning regarding thermal comfort, as well as cooling, both for space and technological purposes, are studied. A part of the course deals with refrigeration and heat pump technology, their theoretical standpoints and application development, both compressor and absorption driven systems and plants, refrigerating storage organization, cold chain for food product treatment, storage and distribution. The other part of the course gives an overview of HVAC (heating, ventilation and air-conditioning) systems. The main principles of the heating and cooling load calculations and psychometrics will be studied and discussed. Particular focus will be on hydronic heating system design and energy conservation.

The purpose of the course is to give an overview of the most significant renewable energy resources and state-of-the-art technologies and their application. The use of solar (thermal and photovoltaic), biomass, wind, hydro, geothermal, hydrogen, wave and tidal energy is discussed through the course as well as fuel-cell and heat pump applications. The possibilities for combining renewable and conventional technologies are presented from the point of view of the future utilisation of renewable energy technologies. Project work is focused on designing combined systems based on renewable energy technologies for various purposes and possibilities for their application instead of conventional ones. The course includes a study visit to built facilities and laboratory installations.
