Investigating Activity Patterns and Time Spent for Exposure Assessment of College Buildings in Korea

Abstract The information about daily activity and time use patterns provide benefit on the analysis of environmental pollutant within microenvironment. The primary objective of this research is to present the relationship between exposure and activity patterns and time spent of individuals. College campus is unique area where students decide activities and spend time respect to them on campus. Dongnam Health College (DHC), as a case study, conducted a student activity survey and observed indoor air quality indicators at individual building. From the result, as student population increases at each building, the concentration of fine-dust and Co2 increases as well. We found that the student population changing time of day is highly correlated with indoor pollutant and also found that the level of concentration varies by time of day as well as day of the week.
