Air exchange rate is a function of building characteristics, external environmental conditions (indoor/outdoor temperature difference and external wind velocity), and occupant behavior (e.g., window- or door-opening). In particular, air exchange due to door-opening behavior occurs unintentionally due to movement of occupants, and occurs in all buildings. The intermittent movement of occupants during the occupancy period can increase the average air exchange rate compared to the non-occupant period. This study aims to quantitatively calculate the change in air exchange rate depending on room occupancy. The air exchange rate according to the number of occupants was calculated using the CO₂ generated by occupants for the office. CO₂ concentration was collected at three indoor points and one outdoor and hallway point. As a result, the air exchange rate during the occupancy period significantly increased compared to the air exchange rate during the non-occupancy period, and the number of occupants per hour was proportional to the air exchange rate. The air exchange rate during the occupancy period significantly increased compared to the air exchange rate during the non-occupancy period in the condition that the external environmental conditions are controlled. Also, the enter or leaved persons per hour was proportional to the air exchange rate. That is, during the occupancy period, additional air exchange occurred due to entry and exit, resulting in a higher air exchange rate compared to the non-occupancy period.
