Ensuring the thermal comfort in societal buildings as hospitals, nursing homes or maternity wards faces extraordinary requirements due to their divergent occupant structure (patients of different health state and health personnel). Therefore, currently available evaluation criteria for thermal comfort in buildings are investigated and contrasted with respect to the occupant types of hospitals. Different static and adaptive comfort models were used to calculate comfort index values on hourly basis. The article shows exemplified simulation results and the obtained comfort predictions for a two month summer period. Large differences were found in the absolute values of comfort indices and relative exceeding hours of thermal comfort. The deviations can be attributed to the way how the models consider the different influences of the occupant's activity (e.g. metabolic rate, clothing) and the environmental factors e.g. (operative temperature). Further differences are caused by the validation data the models are based on.
