| Abstract |
High-rise buildings are constructed rapidly with the growth of urban population, and since demand for occupants’ prospect right, Tower type apartments are increasing. However, the Tower-type apartments cause degradation of ventilation and day-lighting performance compared to the Flat-type apartments. In addition, vertical air movement caused by stack effect arouse a lot of problems in high-rise residential building. The used air flows into the household at the higher floors of the building, and it affects IAQ and ventilation performance. In this study, indoor airflow properties and contaminant concentration properties according to the unit types are analyzed considering the vertical air movement in high-rise residential buildings by network simulation. Also, the usefulness of prediction equation of indoor contaminant concentration was reexamined to calculate the indoor contamination concentration in high-rise building properly. As a result, Indoor contaminant concentration shows different results according to the air-leakage rate by various unit plan types. Also, considering vertical airflow of the building is significant to predict accurate indoor contaminant concentration in high-rise buildings. |
