MESURRMENT OF RELATION BETWEEN WINDOW SHAPE/OPENING PATTERN OF THE EXISTING APARTMENT BUILDING AND CROSS-VENTILATION AIR VOLUME FOR EACH WIND DIRECTION

Abstract

Since the wind direction and speed of natural winds fluctuate, the cross-ventilation air volume also fluctuates, and there is a possibility of excessive indoor airflow and rain, sand, and fallen leaves. Therefore, it is necessary to confirm the actual cross-ventilation volume under the natural wind where the wind direction and wind speed fluctuate. In this research, the optimum window shape and opening pattern are clarified by measuring the cross-ventilation air volume by changing the window opening and closing pattern and the window shape, and analyzing it for each wind direction in the existing apartment building.
