Clothing insulation

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 sari is everyday attire for most women throughout the year all across South-Asia. It is a versatile ensemble because, a single set of garments can provide different levels of insulation just by changing the drape.

In order to know the thermal comfort of bedrooms, we have measured the air temperature and relative humidity in the 27 bedrooms of 11 houses. We have also conducted a thermal comfort survey, quality of sleep and occupant behaviour survey with the residents. Residents are highly satisfied with the thermal condition of the houses, using various thermal adjustments such as fans, clothing modifications, etc.
