As the number of nursery facilities and infants who stay there is continuously increasing, IAQ(Indoor Air Quality)of nursery facilities should be managed strictly and thoroughly because infants are more susceptible to infectionsdue to their low resistivity. In this study the characteristics of IAQ and ventilation associated factors were investigaedfor suggesting a desirable condition for IAQ management. Environmental factors were not much related to IAQcharacteristics rather than internal factors such as structures of the room. And the positive effect of ventilation onIAQ was obvious and seemed to hinge on factors related to window area especially window/wall ratio. Results ofthis study indicate that the structure with broader window area of a room and frequnet ventilation can be an effectiveway for keeping IAQ of nursery facilities clean and safe.
