In recent years, emphasis has been placed on improving workplace productivity. Workplace productivity is defined as “results of workplace activities for investment”. The investments mean indoor environment equipment costs, maintenance costs, and equipment costs. On the other hand, the workplace activities required mean understanding knowledge and information and using them correctly, and realizing new ideas and them. Also, it is expected that the Learning efficiency would be improved by improving the thermal environment of the education site.
The purpose of this study is to find the relation between indoor environment and Learning efficiency.
Questionnaires and measurements of the indoor environment were conducted at the educational site. The target classroom was set to 105 ㎡ and air conditioning was set to 26 ℃. From the questionnaire results, most of the students were satisfied with sound, light and wind environment. However, there were many complaints about the air environment and the thermal environment.
As a result, the environment of the classroom was totally satisfied. As the measurement results, the room temperature was from 26.3 ° C to 26.7 ° C. PMV calculation was performed based on the measurement results. The result of PMV calculation was 0.52 at a certain point. It was close to the comfortable range. Other points were 0.8 or more. They were more than the comfortable range. The result of the PMV calculation showed that it was a little uncomfortable overall.
Therefore, a comfortable indoor environment can be created by improving the indoor thermal environment and air environment. It is thought that these can be made with the introduction of air conditioning and appropriate ventilation. In addition, it is expected to improve Learning efficiency by creating a comfortable indoor environment.
