Investigation of the outdoor thermal comfort and clothing insulation in Hachiko Square in Tokyo

In order to clarify the outdoor thermal comfort and clothing, the thermal measurements (air temperature) and thermal comfort survey were conducted in Hachiko Square which is located in the Shibuya station, Tokyo. (Hachiko is a famous statue of a dog which is a popular meeting place.) The survey was conducted every two weeks and the number of people investigated was 224.  The results showed that the average clothing insulation of the females is greater than that of the men. The clothing insulation is highly correlated with the outdoor air temperature. The equation can be used to predict the degree of clothing insulation in outdoor spaces.
