オフィスの温熱環境が作業効率及び電力消費量に与える総合的な影響

摘要

(1)社員を対象とした被験者実験において、環境条件が25.0℃からrn27.5℃に変化することで、主観評価に基づく作業効率は有意にrn4.0％低下する結果となった（p＜0.01）。また、室内温度と主観評rn価に基づく作業効率の間に有意な相関が得られた（R~2＝0.22，rnp＜0.01）。この回帰式より、作業効率が最大になるのは25.7℃でrnあった。%Various researches highlight that indoor air quality affects performance of workers in offices. Although good indoor air quality improves work performance, it also increases energy consumption. In this study, we achieved a field survey in a real office in order to investigate the relationship between thermal environment, productivity, and energy consumption. In addition to the monitoring of indoor environmental quality and energy consumption, subjective experiments were conducted. In order to evaluate subjective performance, workers and students responded to questionnaires, and to evaluate objective performance, students simulated three types of office works. By calculating room temperature and worker's subjective performance, we demonstrate the correlation between room temperature and worker's performance (R~2=0.22, p<0.01). Results show that 1he room temperature that maximizes worker's performance was 25.7℃.
