Equalization of wind pressure on the inner wall of double-skin of tall buildings for the natural ventilation

This research concerns natural ventilation of the building with double-skin. It aims to get high performance cross ventilation by the control of opening and closing windows on outside exteriorwall and to make the wind pressures on the innerwall to be equal, small, positive value. That is calledpressure equalization.As the result, the building can easily intakeoutdoor air from windows of every walls andexhaust used air through the chimney or air voidlocated at the interior part of the building.From such a viewpoint, the author made the windtunnel tests to decrease and equalize inner wall windpressure using a simple building model, and couldattain the purpose under some conditions
