ABSTRACT: Infants are less thermally adapted to their
environment and can be considered as needing protective measures against
thermal environments. It is not ethical to conduct subject experiments on
infants. Thermal insulation in clothing is an essential control coefficient for
the evaluation of the thermal environment of an infant. A thermal manikin can
be used as an alternative method for carrying out experiments and to control
the thermal manikin based on heat balance. The purpose of this study was to
clarify the thermal insulation of infants’ clothing. An infant thermal manikin
was used to clarify the thermal insulation (Icl)
of typical summer, mid-season, and winter clothing combinations for infants. The thermal insulation of typical seasonal
clothing combinations was 0.30 clo for summer clothing, 0.57 clo for mid-season clothing and 1.02 clo for winter clothing. It was clarified that it
is essential to consider clothing conditions by taking into account differences
in posture and to define the clothing thermal insulation (Icl) when designing and evaluating thermal environments.
When designing and evaluating an infant’s thermal environment, it is essential
to investigate using data from infants.
