Abstract:

Currently, irregular structure greatly affects the user comfort in public spaces. Climate data in the area are not taken into account during the construction phase. High structures concentrated in certain areas create negative wind movements, which affects the user comfort in the public areas around the building. Therefore, wind in high building designs is one of the most important factors in terms of user comfort. With the development of computer technology, simulation models using the method of calculated fluid dynamics (Computational Fluid Dynamics - CFD) in which wind analysis is done have rapidly developed, testing in pre-costed experimental environments, transferred to the computer environments and gained the speed of the experimental process. These simulation models have also been often used in the architectural design process. But the fact that these analyses are carried out by engineers at the final stage of the project, restricts the extent of interventions to be made to improve the negative areas that wind movements create. Interventions are carried out by adding and removing to the project because the project is massively completed, and this situation is not enough to control the wind movements in the open spaces. It is also observed that these simulation models are not effectively used in the application. The purpose of this article is to identify the effects of wind movements while mass settlement alternatives are created in the early stages of the architectural design process, and to reveal the methods for the development of settlement plans in accordance with these data. The wind movements can be visually produced through the collective housing settings defined in the computer's simulation model environment and a view on user comfort in open spaces can be created. Before the use of such models, the problems that occur due to the fact that the wind analysis in the first phase of architectural design is not appropriate in terms of time and cost have now disappeared and in the first phase of architectural design, the use of these programs will be able to create wind-comfortable areas. The study created models of collective housing projects with different settlement plans and features located in Istanbul, and wind analysis was carried out using the Autodesk CFD program. The results of the analysis are the pool, social facility, green space, etc. located in the settlement. Wind movements occurring around the areas have been assessed by considering user comfort, comfortable and uncomfortable areas.
