【 摘 要 】

Indoor Air quality inspection is an important environmental assessment work before the newly decorated space is open to use. Air quality is a dynamic factor affecting environmental health. It mainly evaluates the concentration of harmful volatile gases such as formaldehyde (HCHO), volatile organic compounds (VOCs) in the air, and the concentration of dust and other indicators. The release of these harmful substances changes with the physical factors of the environment that many studies focus on and explore the complex correlations among them. But as a user in the environment, does the behaviour also affect the air quality? In view of this, the study takes the Master's Research Office of Chaoyang University of Technology in Taichung as an example and tries to explore if the release of formaldehyde (HCHO) and volatile organic compounds (VOCs) has any correlation with the cognitive and behavioural activities of people in their environment. In addition to the measurement of the concentration of formaldehyde (HCHO) and volatile organic compounds (VOCs) under the established conditions in the process of the study, the questionnaire survey was used to know the subject's cognition of the environment, such as the freshness of the air, the ventilation of the space, etc. Through statistical analyses, However, the results showed that there were no significant differences in environmental cognition between the before and after measurements. The results also revealed that there were no change of having bad psychological feeling and only a slight change of having bad physiological feeling between the before and after measurements. The study concludes that the assessment of indoor air quality needs to be based on consideration of people's perceptions of the environment and behavioural activities, not just the level of harmful substances in the air. Through the cognition of the environment and the effective intervention in the behaviour process, the harm caused by the air quality problem to the health of the human being can be alleviated to some extent.
