建築物環境衛生検査対象の小中学校における粉塵濃度及びCO_2濃度を用いたAir Stuffinessエビデンスとして行政情報を用いた学校空気環境に関する研究 その3

摘要

平成19年〜平成24年における首都圏X区の建築物衛生法に基づ く空気環境測定結果を用いて，特定建築物小·中学校のCO_2濃度， 粉塵濃度，空気温度，相対湿度に関する考察を行った。その結果，以 下の知見が得られた。%Indoor air environment audit in schools has been conducted regularly by local government in Japan. Recently indoor air quality monitoring in public building has been conducted worldwide. In French school IAQ study, the ICONE (Indice de CON finement d'air dans les Ecoles) index was used to evaluate air stuffiness during occupied periods. One of the purposes of this study is to use the ICONE index to the results of air environmental audit for school classrooms in Tokyo district X. The following conclusions were obtained; In 63 % of elementary schools and 20 % of secondary schools, the ICONE index during summer period showed the lowest value, i.e., lowest air stuffiness, and that during winter period showed the highest. During summer period the percentage of schools with a ICONE score of 3, 4 or 5 in secondary schools was significantly larger than that in elementary schools.
