The distribution of indoor airflow velocity by cross ventilation is influenced by the regional climateconditions, and the location as well as the shape of the building. In this study, CVDHI of 25 cases tochange the number and position of openings at 842 cities in Japan are calculated for the simple housemodel. The results indicate that CVDHI increases relatively in every case from the south to the north ofJapan. The magnitude of the increases is larger along the coastal areas, and smaller in inland areas.CVDHI increases when an opening is placed on an opposite wall in a straight line, and placed at thecorner of the room.
