Study on Ventilation in High-Rise Building Based on Pressure Differences Measured at Elevator Doors

In winter, the stack effect causes problems in high-rise buildings. In order to prevent it, it is necessary to clarify significant factors influencing ventilation behaviors for whole building. In this paper, the pressure differences at elevator doors were measured through one winter for an actual high-rise building in use. Furthermore the correlation of pressure differences with the parameters such as time, the temperature differences between elevator shafts and outdoor air and the outdoor wind velocity was studied. It was suggested that opening of entrance and elevator doors might influence significantly pressure differences, and thus the ventilation behavior of whole building. (C) 2015 The Authors.
