教室の室内環境の現状と．課題に関するアンケート調査: 学校施設における環境配慮方策に関する調査研究　その2

摘要

近年、地球温暖化防止に向けて、環境に配慮した公共施設の整備方策についての関心が高まっている。学校施設の取り組みでは、文部科学省では「エコスクールパイロット・モデル事業」を実施しており、平成9年度から平成23年4月現在までに全国1，235校の認定を行っている。%The Japanese government is funding public school facilities to apply green renovation for reducing environmental load and improving indoor environmental quality. Questionnaire survey on current classroom environment was conducted for 2,138 teachers in elementary and junior high schools across Japan. Thermal environment of classrooms was voted to be hot in summer and cold in winter, with higher discomfort votes in summer. In classrooms without heating, 90% voted the room to be cold in winter even in southern areas of Japan such as Kyushu. Direct sunlight in classrooms was voted to be glary by 48% of the teachers while 70% switched on artificial lighting at all time during the class. Teachers in open-type classrooms were more sensitive to noise from neighboring classrooms than teachers in closed-type classrooms. Indoor air quality was not rated to be a problem, although ventilation systems are rarely installed in classrooms. Green renovation schemes need to take into account the potential needs to improve indoor environmental quality as well as reduction of environmental loads.
