Sustainability as a global idea attempts to improve the quality of human's life in its ecological, socio-cultural and economic dimensions. In compare with other aspects of the quality of human's life, the development of its cultural dimension plays a significant role in achieving the holistic development. Furthermore, the culture centers (e.g. an Art Galleries) designed as interactive and educational places, can contribute to awareness of local and indigenous components of a given society about their cultural heritage, capitals and products. Likewise the mentioned places can support and encourage the educated people to engage in the cultural development process. The key question of this dissertation is "how do the physical characteristics of the galleries' surrounding environment exert influence on its social sustainability?" to respond the later question, this dissertation presents a model that has ability to be used for evaluating, designing, management and management and monitoring of the galleries as being socially sustainable. Moreover, in this dissertation, the mentioned key question is responded through using a descriptive-analytical research methodology. The presented model contains eight benchmarks including; permeability, readability and efficiency, flexibility, community-based educational involvement, safety, environmental comfort, diversity and vitality. In addition, this dissertation presents 32 indicators used for evaluation of the galleries through social-sustainability policies and strategies. The presented model is tested through using Mirza Reza Kalhor Gallery (located in Kermanshah city-Iran) as a case study.

The energy crisis in the seventies of the twentieth century has evolved with a change in attitudes towards the natural, energy, and future of the environment, as the basis for the optimal use of human resources and the stabilization of life on the planet. The greatest challenge for human societies in the 21st century is environmental and energy crises. Sustainable Development Perspective is one of the main theories that have been put forward in response to this challenge. The growth of environmental movements, on the one hand, and raising the awareness of governments about the transboundary nature of many environmental pollution and collective action through international cooperation on the other, has led to "sustainable development" over the last few decades to challenge new perspectives Scientific and practical policies dominate the world. Therefore, the main objective of this paper is to measure environmental sustainability on large scale urban projects with a case study of Hamedan. The statistical population of this research is selected from the chosen type, so that the questionnaire resulting from this measurement was completed by experts related to this subject and the final measurement was done by SPSS software. This assessment and assessment of the environmental sustainability of the six large-scale projects of Hamedan city, which are working with environmental sustainability indicators, have been ranked and each project has been ranked in these indices. The results show that among the large-scale projects of Hamedan city, Rainbow Town Hall project has the highest average in most environmental indicators and has the lowest average in comparison to the project of the tower of Jahanma.

Introduction: The concept of Walking-orientation” alongside Social sustainability” started as two revitalizing approaches to civic and social life with the goal of purposeful rebuild of destroyed or damaged cities due to political reasons such as war or social issues like forming a constructive bond between citizens with an insight to reduction of vehicle domination since 60s. But despite existing this thought among a significant number of urban planners and designers community, during the recent century due to the increase of city sizes as well as the density and quantity of vehicles, human beings have lost their priority over them and with their identity being diminished as the main elements of life in a city, they were pushed to the outskirt of cities over time; An event which could put concepts like interactions” and social bonding” at main spaces and nodes of the cities in a serious challenge.
Methodology: The purpose of this study is to evaluate the cultural sidewalk of Rasht’s Shahrdari square in order to determine the levels of social sustainability and walking-orientation and extracting the affecting components on promoting these two subjects alongside providing theoretical and practical solutions to design high-quality urban public spaces.  The present research is of practical type and descriptive and survey method, using interviews and researcher-made questionnaires based on the statistical population of 384 samples, conducted by Cochran’s formula and Morgan’s table.
Results: The results show the levels of social sustainability and walking-orientation at Shahrdari square of Rasht, with an average of 3.11 out of 5, stands in an acceptable situation. However, a notable point about the results of this study is the presence of more than sixty percent of the citizens to meet the living and occupation-related needs, which challenges increasing the level of interactions as the primary function of this physical environment.
Conclusion: Therefore, attracting the citizens in such spaces of a city which contain significant historical, cultural and social aspects, should be based on their personal desire to participate in these environments, not out of coercion and specifically economic and livelihood needs, but voluntarily in order to form high levels of interactions and social sustainability.  An objective that ultimately leads to the salvation of the spirit of citizenship.

Introduction: Sustainable neighborhood development is a perspective that believes that solving the current problems of cities depends on returning to the concept of neighborhood. The neighborhood is the most fundamental unit of urban development, and the minor scale of attention to various aspects of sustainability as an urban unit with greater control over the city and as a good level for testing new ideas and ways to achieve sustainable urban development has received increasing attention. However, no extensive studies have been conducted on this concept on a micro-scale, and its implementation and quantifying the relationships between the various components of sustainability is also an important issue that has been neglected. 
Methodology: The present study aims to assess the impact of physical - spatial, economic, socio-cultural, transportation and communications, environmental, governance - management on the sustainability of neighborhoods in Javadiyeh Neighbourhood District 16 of Tehran sample was formed. Accordingly, after reviewing the literature related to the issue of sustainability, a conceptual model of the research was formed. Then a questionnaire was surveyed from the residents of the study neighborhood. It should be noted that according to the Cochrane formula, the statistical population includes 381 people. In this study, data analysis was performed using the structural equation modeling method and Smartpls software. 
Results: The results showed that the three paths "governance-management →economic → socio-cultural", "governance-management → economic → sustainability of neighborhoods" and "economic → socio-cultural → environment" With the coefficients of 4/898, 3/208, and 1/988, respectively, were the essential paths influencing citizens' perception of sustainability of neighborhoods and in general, the governance-management component was recognized as the most effective component in determining the sustainability of neighborhoods.
Conclusion: To improve sustainability in different areas, we can emphasize the need to use a strategic plan for sustainable urban development in which special attention is paid to the impact of different components of sustainability on each other.

In recent decades, Chabahar city has faced many problems and issues such as environmental pollution, reduction of ecological power, environmental issues, increasing burden on the environment, increasing the formation of informal settlements (more than 50 thousand people), etc. has been faced that has affected the environmental sustainability of the city. In this regard, this research was conducted with the aim of investigating the status of environmental sustainability indicators in Chabahar city. First, desk researches were conducted in order to know the dimensions, indicators and variables of environmental sustainability, and according to the collected information, indicators and criteria were identified according to the state of Chabahar city, and finally 21 variables in the form of 5 indicators were identified as indicators and criteria. The environmental sustainability of Chabahar city was identified and it was designed in the form of a mutual influence questionnaire and sent to 10 experts. The data were collected and analyzed with MICMAC software. According to the practical purpose of this research, which is to use the results of this research by other researchers and departments of Chabahar city, we tried to identify and use the factors that were known as key factors due to their flexibility and effect on other factors, and be further analyzed. The results obtained from the measurement of environmental sustainability indicators of Chabahar city indicate instability in the city's environmental condition, but the placement of 15 variables out of 21 environmental sustainability variables in the range of key factors shows a place for hope because these variables have flexibility and the power to change. There are other variables that should be considered by city planners. Vegetation; liquefaction and landslides; Drought; presence of water and wind erosion; Soil erosion; flooding; the presence of loose sand dunes in the southeast; The absence of underground water tables and their insignificant exploitation; The emergence and growth of informal settlements in Chabahar city; limited surface water resources; restriction of physical growth in the directions of the west, south and north; Vulnerability of the city's lands and the city's two piers against tsunami due to the increase in the height of the waves; earthquake; Storm; The ratio of durable buildings to the total building were selected as key factors in this research. The vegetation variable has the highest direct and indirect effect, which indicates the very important role of this factor in the environmental sustainability of Chabahar city, which is affected by the climate of the region and the poverty of water resources, and has caused it to be poor in terms of greenness and greenness and cover Plants in this city are only linear along the traffic axes and in the form of spots in the form of a park.

Introduction: Various factors disrupt the thermal energy balance and stability on urban surfaces, often due to unintended changes in climatic parameters and the systemic imbalance of energy systems in cities. These disruptions can lead to serious environmental consequences. Simultaneously, the rapid physical expansion of cities and their adverse environmental impacts have made urban morphological development a central concern. In many global metropolises, addressing the ecological implications of such development has become a key priority in efforts to achieve sustainable urban environmental development. The rising urban population, intensification of construction activities, and increased anthropogenic heat emissions have contributed to a noticeable increase in urban temperatures. This leads to the formation of a warm air canopy over city surfaces—commonly referred to as the Urban Heat Island (UHI) phenomenon. Consequently, the energy consumption for cooling and heating buildings rises significantly.
Methodology: The present study is applied in terms of its objective and descriptive-analytical in terms of methodology. In the theoretical framework, the influencing factors on the thermal energy balance of urban surfaces were identified through a library-based approach and a review of relevant literature.
Accordingly, to analyze the spatial estimation of the impact level of environmental factor indicators on the thermal energy balance of surfaces, and to assess the spatial correlation with this phenomenon resulting from urbanization and urban development changes, the metropolis of Tehran in the year 2021–2022 was selected as the case study.
A cloud-free and clear satellite image of Tehran was obtained by the Landsat 8 satellite using Envi software. The spatial variation patterns of surface thermal energy across the city were assessed using various remote sensing algorithms. Subsequently, the spatial correlation between environmental factor indicator layers and the surface thermal energy layer in the 22 municipal districts of Tehran was estimated using the Band Collection Statistical algorithm
Results: Among all the major environmental factor indicators, four indicators (number of urban parks, NDVI, NDMI, and NDWI) were selected based on their correlation coefficients exceeding 25%. The spatial estimation of environmental factor indicators in the thermal energy balance of Tehran metropolis shows that all four mentioned indicators have a direct association with the environmental dimension. In terms of absolute values, NDWI exhibited the highest correlation coefficient, whereas the number of parks and green spaces showed the lowest. These levels of correlation reflect the increasing role of anthropogenic activities and their impacts on environmental factor indicators. As a result, any change in these patterns will alter the surface heat levels, and consequently, the intensity of the heat island and ultimately the thermal energy balance on the surface.
Conclusion: Since urbanization and urban development are the main factors behind changes in the thermal energy distribution of Tehran's metropolitan surfaces, the implementation of targeted policies in these areas can lead to measurable shifts in environmental factor indicators. Ultimately, such shifts are likely to impact mobility, behavioral, and residential patterns, thereby affecting the degree of thermal energy sustainability across various districts of the Tehran metropolis. All the proposed strategies have been formulated to mitigate ambient and surface temperatures and cool the urban environment.
