Human thermal sensation depends heavily on radiative exchanges between the human body and the surroundingenvironment. Because these exchanges play a crucial role in the thermal balance of the human body, about 35%of the process, human thermal sensation should draw the attention of planners when designing both indoorenvironments and equipment.The present study aims to contribute to this field by proposing a procedure for delineating the optimalcomfort conditions for occupants in most of the articulate and realistic configurations of actual indoor environments.Specifically, this procedure enables accurate assessment of the radiant field surrounding a subject ina given indoor realistic environment and considers its variability with space and time along with the presence ofhigh-intensity radiant sources. The proposed simulation tool contains a set of algorithms in which the degree ofcomplexity depends on the level of accuracy for modelling the radiative heat transfer between the occupants andsurrounding environment.The feasibility of these algorithms for designers and researchers has also been checked for a single roomcharacterised by the presence of windows in two different exposures. This configuration implies a complexpattern of the sun entering the room, which in turn determines relevant spatial modifications of the indoorcomfort thermal conditions. Such complex situations are effectively interpreted by the proposed model.This analysis provides useful indications for suitable design of layouts of the confined space and the size of aneffective heating, ventilating, and air conditioning system to limit the discomfort felt inside the room.
