若年層（16～22歳）を対象とした温熱・空気環境の質が学習効率に及ぼす影響の検討

摘要

1．はじめに近年，各種の経営資源の中で特に人的資産を戦略的且つ効率的に高めていく努力と工夫が求められており，その観点より，室内環境要素と知的生産性の定量的な関連性の把握，ならびに知的生産性向上に寄与する環境設計法の確立といった研究課題の社会的重要性が高まっている。知的生産性に関する研究は経済学や社会学的アプローチにて既に一定の研究蓄積を有する学問課題といえる例えばが，近年になり特に建築学の側面から知的生産性を評価する試みが始まっており，研究成果が報告され始めている例えば。%This study investigated the IEQ effects on learning performance by means of field survey, and the target group was late-teen students. The field experiments were carried out at two technical colleges in Japan. At each college, a ordinary use classroom was adopted for the experiment. In order to evaluate the effects of indoor temperature and outdoor air supply rate, air conditioning units and ventilation fans were controlled at 3 levels (22, 25, 28 ℃; 5, 10, 20 m~3/s/person) and 5 combinations of them were adopted as the experimental cases. In every case, the learning performance was evaluated with a 30-minute examination after a 180-minute video image lecture. The results showed that the examination score decreased in the case of low temperature or low outdoor air supply rate. However, the examination score was not changed in the case of high temperature, which might be caused by seasonal effect. According to comparisons with previous studies, the learning performance of late-teen people was considered to be less affected by indoor environment than that of older people, if their background knowledge of the learning subjects was equivalent to the older people.
