In recent decades, urbanization and the rapid growth of industrialization have led to the release of large amounts of heat energy and increased air pollution in urban areas, especially metropolitan areas, and have created heat islands on these areas.Inefficient urban planning is one of the main causes of heat islands in the city, which has reduced the resilience of cities. On the other hand, one of the criteria of urban resilience is the amount of energy efficiency. So, urban designers should consider the consequences of increasing energy consumption as a result of decisions based on urban design and especially urban morphology as one of the important urban design components that is directly related to the heating and cooling energy demand. Therefore, focusing on the urban texture, the study has analyzed the effect of morphological features of urban texture of hot-arid climate in a case study of Isfahan Shahrestan neighborhood on the energy demand. The method used in the research is a combination (simulation, descriptive and analytical) and for data collection and data analysis, descriptive analysis and univariate analysis have been used, respectively. In order to achieve the objectives of the research, first, the process of extracting indicators affecting the demand for heating and cooling energy has been done using related resources at three levels: block, parcel and building. Then, using the histometric method, the morphologies in the tissue are explained, and to understand the cause of differences in energy demand of species, using simulation of energy demand behavior (energy consumption for heating, cooling) In different situations and by controlling other indicators,Density, area, surface to volume ratio, height, height to width ratio and orientation indices in the lower hierarchy of urban morphology (building and block) were analyzed with Grasshapper software. Findings indicate that the angle of 0 degrees of the building relative to the north direction causes the lowest energy demand.Also, decreasing the surface to volume ratio (building proportions close to square) and height to width ratio, and increasing the number of floors (single building and block) and area (single building and block) will reduce the total energy demand.
