The BSL16 building with courtyard configuration is in fact a different version of BSL13-BSL15 models of building with courtyard. Consequently, courtyard and extra-courtyard measurements came out almost similar. The average wind velocity at points of 3-4-5-6 axes with openings is about 5.50–6.00 m/s. As to the points on windward 1-2 axes without openings, the increase of the wind velocity fell considerably to an average of 2.00 m/s. The wind velocity

As a result, the reference building model BSL-SUZ has a wind velocity of 1.50 m/s when assessed in view of average wind velocities in its region at H level area within the courtyard. There are two different velocity values within the courtyard in building configurations BSL1- BSL2-BSL3-BSL4-BSL5-BSL6. These are; while the average wind velocity is found out at high values up to 0.00H-0.50H level, the openings height at points with openings, a sudden fall occurs in locations without openings in the wind velocity values between 0.50H and 1.25H.

Wind velocities of 4.50–5.00 m/s were found for BSL1 up to openings level 0.00H-0.50H and of 2.00–2.50 m/s above openings level or at points between 0.50H and 1.25H without openings; of 5.50–6.00 m/s for BSL2 up to openings points level and of 3.50–4.00 m/s above openings level or at points without openings; of 5.50–6.00 m/s for BSL3 up to openings points level and of 1.50 m/s above openings level or at points without openings; of 7.00–7.20 m/s for BSL4 up to openings points level and of 2.00 m/s above openings level or at points without openings; of 6.50–7.00 m/s for BSL5 up to openings points level or of 2.50–3.00 m/s above openings level or at points without openings; of 7.00–7.50 m/s for BSL6 up to openings points level or of 1.50– 2.00 m/s above openings level or at points without openings. There are average wind velocity values for other building configurations up to courtyard H height. Those are average velocity values of 2.00–3.00 m/s for BSL7, 3.50–4.00 m/s for BSL8, 1.50–2.00 m/s for BSL9, 3.00 m/s for BSL10, 2.50–3.00 m/s for BSL11, 3.00–3.50 m/s for BSL12; 3.50 m/s for BSL13, 1.50 m/s for

As a result of the experimental study made; it is an experimental study aimed at presenting preliminary information for studies to be held thereafter and form a base for the designated data about exactly how much cooling and ventilation would occur within a courtyard building using numerical methods for the air flow values acquired within the courtyard. The results of this study can be summarized as follows. Courtyards of surrounded courtyard without open-

Although openings rates are same, the position of the openings becomes increasingly significant. Proportional velocity increases occur as the openings rate grows on windward and leeward opposite surfaces. In the event of different openings rates on windward and leeward opposite surfaces, velocity increases become considerable as the openings on the windward surface grows. Very different wind velocity and ventilation characteristics are observed due to differentiation of the positions with openings in courtyard options with same openings rates. In the event of unilateral openings arrangement, the openings on the windward surface are effective at the

average between 0.50H and 1.50H is about 2.50–3.00 m/s (Figures 4 and 5).
