Abstract
This study aims to examine the effect of walking environment and time outdoors on thermal comfort when staying indoors, based on human physiology. Using the joint system thermoregulation model, we modelled the behaviour of staying in an indoor environment after walking in an outdoor environment (sun or shade) for various times during the summer. We then analysed the changes in mean skin temperature, mean skin wettedness, and standard new effective temperature over time during the stay indoors, and compared them with the steady-state conditions. The results showed that the dynamic physiological state and the time to reach a steady state during the stay indoors differed depending on the transient outdoor environment and walking time, that is, thermal history. For thermal comfort after 60 min of staying indoors, we presented the outdoor walking time for which the standard effective temperature, based on steady-state conditions, can provide reasonable information. This study will be a step towards evaluating indoor and outdoor thermal comfort considering the thermal history in a consecutive manner.
