Most pedestrians suffer from the heat stress when they are walking on the town street in summer day. The heat stress of human body at the street influence on the human activities such as the student performance, the productivity, etc. in building. Therefore, the research about reduction of heat stress for pedestrian is an important work. The researchers carried out so many issues about thermal environments in the building in world wide. In contrast, there seems to be the poor publishing about the reduction of heat stress for the pedestrian. In the summer day, the streets are so hot because density of sun radiation is so high, the air temperature of surrounding is high. The street trees is a good material for the sun shade in the street. In this research, we survey on two thermal environments of streets. First street has no tree and second one has high density trees. The purpose of this research is to provide the raw data for heat stress reduction research and the reduction method of heat stress for the pedestrian who is walking on the town street in summer day, through that survey on Mean Skin Temperature(MST) and Thermal Sensation Vote(TSV) for the pedestrian subject on the street in summer day in Busan Korea. In conclusion, The pedestrian subject answers "warm" in the street of high density trees. In contrast, the subject answers "hot or very hot" in the street of no tree. MSTs of pedestrian subject was 33.6℃ in the street of high density trees, 34.1℃ in the street of no tree. |
