Team "Indoor Climate Technology"

The Indoor Climate Technology team addresses issues related to thermal comfort and air quality as well as to air flows and thermal flows in rooms.

Research focus

The Indoor Climate Technology team addresses the subject of indoor comfort while considering not only thermal but also air quality aspects. One focus is the characterization and quantification of air flows and pollutant concentrations as well as their efficient dilution of removal, for residential and non-residential buildings. In particular for indoor areas in manufacturing sites, concepts are developed and verified for air pollution control at workplaces and thus the detection of pollutants. In addition to the removal of substances such as CO2, the focus has shifted to the investigation of aerosol-related infections and protection through various ventilation measures. Investigations are based on computational fluid dynamics or in-situ or laboratory tests (e.g. in room air flow laboratory).
