Abstract
Abstract This study was carried out to investigate and shed light on the complex theoretical concept of place, as a continuing dynamic phenomenon, in architecture. To this end, it has looked into the historical evolutions and retrieval of the Shah Wali complex in Taft. Considering the topic and the goal of this research paper, the morphological analysis as a tool used in the interpretive-historical research the method and the process of change and continuity of form was selected. The findings of this study indicate that this place, as a form, has always been subject to change. These changes could be categorized into two groups: (a) the changes which have been gradual and have taken place over a long period and (b) those which have taken place over a short period. The gradual changes have taken place starting from the Timurid to the Safavid era, at which point the complex has reached completion and evolved as a complex. After the initial developments of the complex, the complex underwent some short period changes in its components and spatio-temporal structure. These short period changes coincides with the demolishment of the old Takiya and construction of the new Takiya. Following these short period changes, the gradual changes of the second stage starts. As an implication of this research, it is suggested that urban designers and conservationists in particular revisit the theoretical underpinnings of the terms and concepts in the process of continuity and change of the historic dynamic complex, in order to fully understand and apply appropriate strategies in the design and the conservation.

Abstract
Urban morphology, including buildings’ typology and their configuration, affects sky view factor and insolation, which are two of the most influential parameters in urban microclimate. These become even more important in extreme environmental conditions. In this research, challenge was to generate various rule based urban morphologies in a parametric environment. Then, to evaluate them based on mentioned parameters to find the fittest climate responsive morphology. The evaluations are done using grasshopper definitions connected to Ecotect and genetic algorithms in grasshopper in a relatively short computing time. Introducing a high speed and user-friendly environment for designers to introduce forms and evaluate them in several iterations was a main consideration. The tool consists of two parts. First, the generative algorithms to create various rule based morphologies. Second, the analysing algorithms, which find the fittest climate responsive urban morphology based on insolation and sky view factor. As a case study, the program is used on different urban morphologies in Yazd to find the fittest solution. Gaining the maximum sky view factor while having minimum insolation on building surfaces is ideal in hot and arid climate. Anyhow, these two suggest contradicting solutions for urban form. Based on the existing urban fabric in Yazd, various block typologies and their arrangements are generated parametrically. In each scenario, iterations of evaluation find the most suitable ones. After comparing the fittest versions of different types, the most proper building typology, collective arrangement of them and the best orientation are provided as result.
