Abstract This study focuses on the numerical analysis by means of computational fluid dynamics of the variation in the overall comfort in a small office/room, due to the presence of heat-generating and non-heat generating elements. The study is valuable in understanding the correlation between internal heat generation by humans and the quality of the indoor environment. Two types of the radiator were compared using two different geometric models. Double-panel radiator and ventilation radiator was used for two different geometric models by keeping other geometry parameters unchanged. Various case studies have been analyzed to ascertain the impact of computer, monitor, and occupant individually on indoor environmental quality for both the models. By introducing two occupants, two monitors, and two computers in an empty room, the average indoor temperature of the room raised by 22.64% and 25%. Due to an increase in the average temperature of an indoor environment, occupants would usually feel uncomfortable. To optimize the models, radiator heat flux has been reduced. The study would be worthwhile for the design and optimization of domestic rooms/offices with occupants, furniture and various other involuntary heat sources.
