The purpose of this study is to measure and analyze the concentration of indoor fine dust and carbon dioxide according to the general life of occupants over four seasons in a residential space, and to provide data for finding ways to maintain health of occupants. The results of analyzing the measurement results are as follows. 1) As a result of long-term measurement of living space, indoor fine dust and carbon dioxide concentrations changed according to living activities such as cooking and sleeping by month and season. 2) As a result of measuring and analyzing changes in indoor fine dust and carbon dioxide concentration, in the case of indoor fine dust, fine dust generated indoors has the greatest effect continuously for four seasons than fine dust caused by external inflow, and in the case of carbon dioxide, Carbon dioxide produced by respiration has the greatest effect. 3) Depending on the season, fine dust and carbon dioxide generated indoors were often high in the season when the windows were frequently closed, and in the season when the window was opened for ventilation, the fine dust and carbon dioxide generated in daily life were reduced. Therefore, fine dust and carbon dioxide in residential space showed greater concentration difference according to living activities compared to external factors. In order to remove fine dust generated indoors and reduce carbon dioxide in residential spaces in the future, it is necessary to consider fine dust and carbon dioxide reduction measures considering monthly, seasonal, and spatial life patterns.
