THE INFLUENCE OF NUDGE OF THE AIR QUALITY ASSESSMENT ON THE VOTES OF ODOR INTENSITY AND ACCEPTABILITY

Abstract

An Experiment on perceived air quality using sensory subjects was conducted in room A where one year passed after an interior repair work, and in room B where 25 years passed after the construction. In room A, the VOC concentration of the paint origins was slightly high. The subjects were divided into two groups, i.e., the group, who assesses perceived air quality using the questionnaire which specialized in the air quality (questionnaire II), and the other group using the questionnaire which asks thermal comfort, lighting comfort, noise perception and perceived air quality (questionnaire I). For the assessment by the group which used questionnaire I, there was no significant difference in the voted odor intensity of room A and that of room B. For the assessment by the group which used questionnaire II, the odor intensity of room A was significantly higher than that of room B. The nudge to the air quality assessment by the difference in a questionnaire might affect the perceived air quality assessment.
