A Study on the Evaluation Tendency of Thermal Sensation in Tropical Region - Targeting short time residents -

Abstract

Climate change is getting more and more serious issue in the world. This is known as caused by the increase of carbon dioxide. To stop the increase, many countries agreed to the Paris Agreement in 2015. When to discuss the climate change, temperature drop and increase are focused more often. The big change of the temperature, especially the rise of the temperature, causes the more usage of air conditioning system, and it also causes more energy consumption. In addition, the usage of the air conditioning system is affected by both indoor and outdoor thermal environment. The temperature setting of air conditioning system tends to be lower in the countries situated in tropical region than the countries in the other region. This happens because the thermal sensation of human is easily affected by the outdoor environment. For that reason, to grasp the tendency of thermal sensation in outdoor space is important. In addition, the tendency of short time residence is necessary to wipe out the influence of the thermal environment adjustment by long time living. For that reason, this research targeted the thermal evaluation tendency of short time residents in Bangkok and carried out subject experiments in outdoor spaces to develop landscape design method. As the result of analysis, a different tendency was grasped at one of the measuring points with open sky.
