Oleksandr Melnyk received his master’s degree in renewable energy systems engineering at the University of Applied Sciences Technikum Wien. In his thesis, he investigated the energy flexibility potentials based on building information modelling. For this work, he received “Energietechnik-Preis 2020” award from the Austrian Association of Electrical Engineers – OVE. In 2017, at China Three Gorges University (Department of Architecture and Urban Planning) Oleksandr worked on the development of energy-efficient construction concepts in a subtropical Asian climate with a specific focus on improved quality control of innovative building renovation projects. Apart from renewable energy systems and engineering, his interests include methodology of science, social sciences, history of art and philosophy.
