It is not ethical to conduct experiments on infants regarding the thermal environment. Therefore, to examine the thermal environment of infants, experiments and simulations using a human body thermal model may be feasible by clarifying the human body coefficient values of infants. When focusing on the heat transfer area of the infant’s body coefficient values, the body surface area and solar radiation area factor have only been clarified as the standard. The essential basic data for examining the thermal environment of infants have not been sufficiently obtained. Therefore, the purpose of this study was to determine the clothing area factor for infants’ clothing in a typical season. The clothing area factor of infants clothed in summer, mid-season, and winter clothing was measured using a photographic method. The clothing area factor was 1.22, 1.42, and 1.90 for summer, mid-season, and winter clothing, respectively, indicating a significant seasonal difference. It was also found that the clothing area factor was significantly greater for infants than for adults.
