This study utilizes the two-chamber model to simulate naturally ventilated airflow through a window opening in a common- type bedroom in Taiwan. Standard kepsilon turbulence model is implemented to account for such a natural convection flow pattern. The driving force in this space is mainly the heat flux generated by occupant's skin. The result shows that under normal operation indoor, carbon dioxide ( indicator air contaminant for IAQ ) is less than 1000 ppm, ASHRAE Standard recommended.
