The wind pressure coefficient is the basic driving force of wind-induced natural ventilation. The windvelocity along the building wall is also important for wind environment in balcony (veranda) or windowsand is the moment of inertia for the air flowing into rooms. These two values of the five-storiedapartment building with/without veranda were measured by wind tunnel test using scaled model. Theexperimental conditions are the faade type, the shape of veranda and wind direction.
Gives the results of an investigation on the combined effect of balcony, opening design and internal division on the indoor airflows pattern of a living zone located on the second floor of a two storey building. It was done using N3S software. The local average velocity coefficient as a function of the position in horizontal sections of 1.00 and 1.50 m in height was used, for activity with sitting and standing positions. The number of measurement points in the living zone were used to calculate the average velocity coefficient.
