Statistics of Vital components from overviewing the Traditional Courtyard Houses of Yazd11

Life is one of the valid categories in architecture. In spite, the fact that some experts in the contemporary period have paid attention to the issue of life and the effective components in its formation as a special quality, but in architecture of this period, one rarely sees the presence of vital components in the constructions. This is despite the fact that in the architecture of the pre-modern periods, these features can be received so that it creates a level of quality. In the architecture of the pre-modern period the house has more value among the buildings built. In these houses, the courtyard is one of the important spaces as the focal attention and through this the dignity of all the house spaces originates from it. Therefore, the main research problem is that; What are the vital quality components in Qajar architecture of Yazd? In order to approach a level of physical and mental life in the houses of the contemporary period, knowing the components and the possibility of their application is the main goal of this article. Qualitative research method is among the methods that provide the possibility of obtaining reliable results in this research. Therefore, based on the foundation data method and field research, we will introduce extractive components. For this purpose, by selecting examples of houses of the Qajar period in Yazd, which seem to have this quality, an attempt has been made to identify the components that create or strengthen vitality in architecture. The research results indicate that the evaluated components, in addition to having diversity, also follow a semantic level, so that these levels are closely related to the territorial talents and knowledge skills and architect vision. Also, the components explained by some architectural theorists, including Alexander, can be proven in the architecture of Qajar period houses in Yazd and have relative validity.
