SURVEY OF INDOOR ENVIRONMENTAL QUALITY IN OFFICES DURING THE COVID-19 PANDEMIC (PART 2): RELATIONSHIP BETWEEN INDOOR ENVIRONMENT AND ENVIRONMENTAL SATISFACTION IN 2020 AND 2021

Abstract

The study aims to clarify the effect of indoor environments on office workers’ satisfaction with the thermal and air environment. Environmental measurements and questionnaire survey were conducted on 22 office buildings and their workers in 2020 and 2021 during the COVID-19 pandemic. Satisfaction with the thermal environment showed a quadratic relationship with temperature and a negative correlation with PM_2.5 mass concentration. Also, satisfaction with the air environment indicated a positive correlation with relative humidity and a negative correlation with CO₂ concentration and PM_2.5 mass concentration. Therefore, workers’ satisfaction can be enhanced by maintaining the indoor environments.
