Abstract This study is a simulation for natural ventilation application in a high - rise apartment building. 1) Ventilation efficiency increased with the increase of the area of the opening compared to the floor area in the ventilation efficiency analysis according to the opening area and the number of ventilation. That is, the ventilation number increased by 0.033 times at every 50% increase of the opening area of 2%. The space with the tangent opening of the outside air maintained the opening area compared to the floor area of 7%, and the space located at the side of the outside air maintained the opening area compared to the floor area of 9-13% and maintained the ventilation frequency more than 0.1 times. 2) In the comparison of the ventilation amount according to the shape of the window, the ventilation amount was calculated in the order of double skin (DSF_PAF)> double skin (DSF)> single skin (SSF_Top). Therefore, in order to maintain a wide opening area stably, we proposed the use of a dual envelope (DSF_PAF) with a window with the greatest ventilation in a box-type double envelope system, which has excellent control over individual spaces and is not affected by the height of the building.
