With scale models of single corridor type apartment unit,
various interior wind velocity ratios are measured and typical
air flow path through openings of rooms are visualized. As
the results of scale model experiment, natural ventilation in
a apartment unit is greatly increased when entrance door is
open. Therefore, following measures should be considered to
achieve proper indoor natural ventilation.
1. Projection of balcony overhang should be designed adquate
ly and when windows are installed in balcony the opening size
and location should be properly provided.
2. Location of doorways in each room and layout of partition
walls should be arranged appropriately in a apartment unit plan
to increase wind velocity ratio.
