Alexander Rosemann is Professor and Chair of Building Lighting at the Unit Building Physics and Services in the Department of the Built Environment at the Eindhoven University of Technology (TU/e). He studied electrical engineering at Technical University of Berlin and University of Manchester. He graduated from TU Berlin in 1997 as Diplom-Ingenieur in Electrical Engineering. He completed his master thesis in Colourimetry at the Federal Institute for Materials Research and Testing (BAM). From 1998 to 2004 he was a scientist at Technical University of Berlin. In 2001, he received his PhD on his work in the European research project ARTHELIO on hollow light guides for the combined utilization of daylight and electrical light. From 2001 until 2004 he was focusing on hybrid illumination systems, autoadaptive control systems, bi-directional measurements and a calculation method for determining the energy use for lighting in buildings. From 2005 to 2007 he was a postdoctoral fellow at the University of British Columbia (UBC) in Vancouver, Canada. His research focused on an economically feasible daylighting system. In 2007 he received the habilitation (venia legendi) from TU Berlin on daylight technologies. In the same year, he joined BC Hydro, the electrical utility of British Columbia, Canada. Initially focussing on energy-efficient lighting projects, he became specialist engineer Codes & Standards in 2009. He has been involved with several standards and chaired several standard committees on energy-efficiency in lighting and electronics at the Canadian Standardization Association (CSA). He is also a member of the Task Group Lighting and Electrical Power of the National Energy Code of Canada for Buildings. Since April 2014, he is appointed as full professor and chair of Building Lighting at TU/e. For his fast and excellent studies, he received the Erwin-Stephan-Preis”” of Technical University of Berlin. The “deutsches farbenzentrum e.V.” (German Colour Centre) awarded him the “Karl-Miescher-Preis” for his Diploma thesis. He is actively involved in committees of CSA, CIE (International Commission on Illumination), the IES (Illuminating Engineering Society) and ISO (International Standardization Organization).
