Abstract: | Current thermal comfort indices do not take into account the effects of wind and body movement on the thermal resistance and
vapor resistance of clothing. This may cause public health problem, e.g. cold-related mortality. Based on the energy balance
equation and heat exchanges between a clothed body and the outdoor environment, a mathematical model was developed to determine
the air temperature at which an average adult, wearing a specific outdoor clothing and engaging in a given activity, attains
thermal comfort under outdoor environment condition. The results indicated low clothing insulation, less physical activity
and high wind speed lead to high air temperature prediction for thermal comfort. More accurate air temperature prediction
is able to prevent wearers from hypothermia under cold conditions. |
