As such, the core focus in teaching and research is a holistic design approach for buildings in consideration of sustainability and energy-efficiency. He guides scientific personnel within research projects on the application of simulation-software as planning instrument for the numerical calculation of thermal, lighting and flow specific processes. These insights with practical relevance can be made in the fields of thermal comfort, energy consumption and daylight supply. In research, the chair is conducting several projects with various sources of funding from public or private sector, on state, federal and European level.
