Abstract
The characteristics of wind induced natural ventilation of dwellings are analyzed both by field experiments and wind tunnel experiments. The distributions of wind pressure coefficient of walls and those of wind velocity in rooms are clarified in detail. The experimental model house has a ventilating opening at the roof in order to increase the amount of natural ventilation. The results are as follows. (1) The correspondence of the wind pressure coefficients between the field experiments and the wind tunnel experiments is quite well. (2) The window at the roof has great effects on increasing the amount of natural ventilation. (3) The velocity distributions on room are greatly influenced with the conditions of opening. (4) In summer season the ET (New effective temperature, defined by ASHRAE) value in the room is effectively decreased by the air flow induced by the natural ventilation.
