قاجاریه ایران

The facade architecture of the introverted historical houses of the central plateau of Iran is more evident in the central courtyard. According to the diversity of the central courtyard facade architecture in multiple fronts, it seems that there are various effective factors in the formation of the courtyard facade architecture of historical Qajar houses, and it is necessary to identify the effective factors comprehensively and in terms of impact. be classified from high to low. The research seeks to know what factors and sub-factors are effective in the formation of the architecture of the central courtyard of historical houses of the Qajar period in the hot and dry climate of the central plateau of Iran (with a case study of Qazvin city)? What is the classification of these factors and sub-factors in the formation of the architecture of the central courtyard view according to the degree of influence? Identifying the influencing factors on the architectural formation of the facade of the central courtyard of historical Qajar houses (with a case study of Qazvin city) and classifying these factors based on the degree of influence of each factor. The type of research is fundamental in terms of the goal, and the research method in response to the big question is a survey of basic theories and a field visit to the historical Qajar houses of Qazvin city and a local conversation and a conversation with elites. In response to a detailed question, the Delphi method has been used to rank the impact of each of the factors and sub-factors based on the opinion of experts and professionals familiar with the architecture of the Qajar house and facade. In the following, a theoretical model was proposed and this model was reviewed and tested in the case of the research of ten Qajar historical houses in Qazvin. Eight main factors and thirty-three sub-factors were identified in the formation of the facade architecture of Qajar houses in Iran. The eight main factors in order of influence include: economic, climatic, construction technology, socio-cultural, aesthetic, spatial, political and urban planning. Each of these factors have been relatively effective in the formation of the architecture of the central courtyard. According to the opinion of the experts of the basic theories and the test of the presented theoretical model, the most effective is the "economic factor" and the least effective is the "urbanization factor". In the ranking of thirty-three effective sub-factors, the most effective sub-factor was "radiation" and the least effective sub-factor was "urban architecture".
