Reference excerpt

Soteris Kalogirou is a Cypriot mechanical engineer and academic whose work focuses on solar energy, renewable energy systems, and the application of artificial intelligence in energy technologies. He is a professor at the Cyprus University of Technology.

Early life and education Kalogirou was born in Trachonas, a suburb of Nicosia, Cyprus. He earned a Ph.D. in Mechanical Engineering from the University of Glamorgan in 1995. His post-doctoral research examined the use of artificial intelligence methods for the analysis and simulation of solar energy systems.

Career From 1982 to 1987, Kalogirou worked as a Building Services Consultant at Intersol Engineering. He subsequently held various academic positions at the Higher Technical Institute of Cyprus between 1987 and 2007. In 2008, he joined the Cyprus University of Technology, where he is a Professor of Thermodynamics, Heat Transfer and Solar Engineering in the Department of Mechanical Engineering and Materials Science and Engineering. At the Cyprus University of Technology, he has supervised postgraduate and doctoral students and contributed to the development of research programs in renewable energy. His work has included participation in European and international research initiatives focused on sustainable energy systems and technologies. Kalogirou publications have been widely cited in the field of renewable energy engineering, reflecting sustained academic influence in areas related to solar energy utilization and energy system modeling. He is the founder and director of the Archimedes Solar Energy Laboratory (ASEL) at the Cyprus University of Technology, where a significant portion of his research has been conducted.

Research and contributions Kalogirou's research contributions are centered on the advancement of solar energy technologies and their integration into practical applications. His work has explored both theoretical modeling and experimental validation of solar thermal systems, including flat-plate collectors, concentrating systems, and building-integrated solar technologies. He has also contributed to research on solar-driven desalination systems, focusing on methods to enhance freshwater production using sustainable energy sources. In addition, his work has examined hybrid energy systems that combine different renewable technologies to improve overall energy efficiency and reliability. A typical example is the hybrid photovoltaic/thermal collector that combines electricity and thermal energy generation within a single solar panel. This design removes the extra heat generated by photovoltaics, keeping their electrical efficiency at a high level, prolonging their useful life, and utilizing the heat thus collected for useful purposes, such as solar water heating preheating or space air heating. Kalogirou's research involves experimental and theoretical studies, as well as advanced thermodynamic analysis such as exergy analysis, applied to solar thermal and photovoltaic technologies in buildings, industry, and power generation. His studies have included theoretical modeling and simulation, validated through controlled experiments using a solar simulator and long-term outdoor performance monitoring. Research findings have been applied in various sectors, including residential buildings, schools, office buildings, and industrial systems. Some of his research has been incorporated into commercialized technologies.

Editorial roles Kalogirou is currently the Editor-in-Chief of Renewable and Sustainable Energy Reviews since 2025. From 2005 to 2014, he was an Associate Editor of Renewable Energy, followed by a decade as Editor-in-Chief (2014–2024), and currently holds the title of Editor-in-Chief Emeritus. He was also Associate Editor of the Energy journal (2006–2010), Executive Editor (2010–2012), followed by a decade as Deputy Editor-in-Chief (2013–2023), and currently holds the title of Honorary Editor (2024–present).

Worked examples

Example 1 — a first encounter with Soteris Kalogirou

Start with the simplest possible case. Write down what Soteris Kalogirou claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Soteris Kalogirou before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Soteris Kalogirou ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Soteris Kalogirou

In research: Soteris Kalogirou appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Soteris Kalogirou in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Soteris Kalogirou is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century mechanical engineers, Academic staff of the University of Cyprus, Alumni of the University of Glamorgan, so understanding it makes those chapters shorter.
In everyday life: Look for Soteris Kalogirou outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
