Description

In winter, environmental problems caused by the stack effect occur in high-rise buildings. In order to prevent the stack effect, it is necessary to estimate the behavior of the natural ventilation quantitatively for a whole building. In this study, we measured pressure difference at elevator doors in an actual building through one winter, and at the same time, the numerical analysis by the airflow network model were performed. As the results, the calculated pressure differences at the elevator door on the top and bottom floor showed good agreement with the measured values for both nighttime and commuting time.
