Assistant professor Košir is a head of Chair of Buildings and Constructional Complexes at the Faculty of Civil and geodetic Engineering, University of Ljubljana. He finished his Bachelor degree in architecture in 2003 and received his PhD in civil engineering in 2008. Currently he is lecturing on subjects regarding energy efficiency in buildings, daylighting, building envelope design, smart buildings and indoor environment at the Faculty of Civil and Geodetic Engineering as well as at the Faculty of Health Sciences.

His primary research interest is in the field of building energy performance and daylighting in connection to the design of high performance buildings. In this respect, he focuses on performance of adaptive building envelopes and theirs coupled thermal and visual performance. In recent years his interests have broadened to the field of bioclimatic climatological analysis in respect to the past, current and future energy performance of buildings.

Research conducted over the past 10 years has increased the insight into the interconnectedness between the occupants, buildings and the environment.
