The role of the courtyard in the configuration of the mosque in orrer to improve functional efficiency by using space syntex

The role of yard in the Iran architecture Undeniable and sometimes are architectural design requirements, due to geographical and climatic conditions. Yard, what on public land (mosque school, caravanserai, etc…) and non-public (such as houses) is often not removed from the body design. In modern mosques, according to the density of buildings and land issues in many cases, the courtyard of the mosque has been removed or the configuration of the body, where it is considered to be variable. While its role in changing the functional efficiency overlooked. The aim of this study is that there are different roles create or increase it is the guarantor yard and based on the creation or improvement of functional efficiency based. Proof of this process the role of the mosque yard using two methods of drawing graphs and its data for as space syntax mathematical well as software is Depth map. to prove the functional efficiency definition of space efficiency provided and then based on this definition, operational efficiency and introduced six indicators will be described indicators link and integration by mathematical justification and proof as space syntax, the selection criteria will be shown with passenger as well as indicators of depth, axial space and convex space with the use of Depth map software and to be analysis outcomes that prove and to prove the yard in changes in the functional efficiency of the courtyard of the mosque will be discussed. the results show the central courtyard design with rectangular geometry is the highest level of functional efficiency compared to other models. according to this research questions in the following cases studied: whether or not there is a courtyard in the configuration mosques is necessary? Proper positioning of the yard in order to improve efficiency and performance like ? What is the most suitable geometry for the yard? .1-The hypothesis of the study is available as follows: The layout of the yard in the spatial structure of the mosque have been set in the geometric center and as well as the appropriate geometrical.2- To enhance the functional efficiency of the mosque, the location of the yard should be considered that is most relevant to indoor space.3- Yard geometry must be such that the axial space proper in there and convex space is minimized. In order to prove this hypothesis (1), first hypothesis (2) and (3) studied considering and the results of these two hypotheses (1) can be achieved. hypothesis (1) will pay the importance of the yard or the lack of it In promoting functional efficiency of mosques hypothesis (2) will pay to the proper location on the courtyard the spatial structure in order to enhance functional efficiency mosques the spatial structure in order to enhance functional efficiency mosques In order to investigate the role of location in improving efficiency should yield yard index "integration", "link", "choice" and "depth" are used. also check on the functional efficiency of the geometry of the mosque courtyard, Index "convex space" and "central space" is used.
