jaue2015006: Potential of Cross Ventilation in Detached House on Regional Climate Information

Abstract

The relationship between the opening area, the main wind direction and ventilation ratio which is a building performance indicator of ventilation is analyzed based on the real housing plan. The ventilation ratio was increased when a ventilation circuit was formed in the house, and the opening area facing the prevailing wind direction was large. However, the relationship between the ventilation ratio and the opening area facing the south side was not confirmed, because the south side opening area was much larger in all objective typical detached house models. The relationship between the housing arrangement, adjacent building interval and the average ventilation ratio which is a location indicator of ventilation is analyzed intended for modeled residential district. The difference of ventilation ratio between windward and leeward side houses which is occurred in the case of aligned arrangement, is reduced when the adjacent building interval increases or it becomes a staggered arrangement.
