富山市の小学校の教室内気温およびWBGTの通年モニタリングによる児童の学習環境の実態調査

抄録

As of 2017, more than half of elementary and junior high schools in Japan spent the summer without air conditioning, and although it was assumed that the environment inside classrooms during the summer was uncomfortable, the actual situation was not fully understood. In this study, temperature and wet bulb globe temperature (WBGT), an indicator of the risk of heat stroke, were monitored over time in the classrooms of an elementary school in Toyama city from September 2017 to July 2018 in order to determine the actual condition of the children's learning environment. The classrooms in the reinforced concrete building were the hottest in July among the days when children attended school, with temperatures in the classrooms up to 9.6℃ higher than the outside temperatures. Even though the temperatures were within the standard range, the WBGT levels were sometimes higher than the warning level. In order to create a comfortable learning environment for children during the summer, it is necessary to install air conditioners and control WBGT.
