Due to COVID-19, in office buildings frequented by an unspecified number of people air currents discharged from convective heating systems installed near the ceiling or windows to handle envelope load are believed to be the main cause of the spread of virus. Consequently, the need for radiant ceiling heating panel, which utilize the principle of natural convection, is becoming increasingly significant. To replace convective heating systems and apply radiant ceiling heating panel, it is necessary to examine whether they can promptly respond to changes in the envelope load and secure the thermal output required to handle the heating load without causing discomfort, such as downdraft. In this study, the applicability of radiant ceiling heating panel to the perimeter zone in terms of thermal comfort was evaluated. To achieve this, the thermal characteristics of radiant ceiling heating panel were examined, and a simulation model capable of evaluating the thermal comfort of radiant ceiling heating panel applied to the perimeter zone was constructed. Based on the results of the thermal comfort assessment, thermal output conditions for applying radiant ceiling heating panel to the perimeter zone were proposed.
