4. Conclusions

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 openings (BSL-SUZ) type have minimal air velocity.

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 highest level and those on the leeward surface at the lowest level. While there might be decreases in the average air movement velocity due to the relative positions and area rates of openings, points where it increases at spatial distribution may also be formed.

With this study, several experimental measurements and numerical studies will be held in relation with the building form and surface openings in courtyard buildings at different configurations and at different dimensions. As a result, it will constitute a very good reference to all studies to be held hereafter with regard to the reliability and availability of all measurements conducted and results found, and constitute a base to the design data in various conditions.
