In the past, cities have been good examples of energy-efficient urban design in terms of ecological constraints. Looking at traditional cities and comparing them with modern urban planning, we see adverse environmental consequences in the scale of design of building units and the spatial structure of cities. Therefore, it seems necessary to identify the effective factors in the design of traditional sustainable cities, using simulation software before the project or in the proposed options, to the optimal forms in the components (individual buildings) and Urban combinations (urban textures) was achieved. The present research combines descriptive-analytical methods, typological studies, drawing and simulation of models, following the analysis of energy consumption and thermal comfort in different types of building forms, urban blocks, and spatial structure of Isfahan in ۴ historical periods. Therefore, by using energy simulation software (Design Builder) and thermal comfort (Envi-Met) and analysis of Space Syntax, the relationship between independent variables (physical and spatial characteristics of the urban fabric) and dependent variables, the amount of energy consumption (to provide heating, cooling, and lighting) and thermal comfort, in each of the proposed scenarios, has been investigated. Based on the results, it is possible to formulate guidelines for the climatic design of urban structures in the form of three components; The system and pattern of segmentation and segregation of urban land, the shape and characteristics of the mass/space in urban contexts and the pattern of the network of texture passages, regulation, and operational construction. The dominant forms of the Qajar period are more sustainable forms than other historical periods in terms of energy performance and adaptation to the climate. Also, spatial structures with the highest degree of spatial connection can provide a higher percentage of thermal comfort conditions in urban open spaces.
