One of the fundamental notions of realization of sustainable city within the framework of the theory of sustainable development is what affects the urban green spaces as well as the influence they may have. As the upshot of years’ worth of experiences in the ideology of Iranian urban design, Iranian garden is of magnificently high position which possesses the potentials to act as the green space with a variety of functions to serve the promotion of sustainability in today’s cities. Closely studying Dolat Abad garden as one example of the exquisite Iranian garden architecture in a comparative analysis, this study exامینes the role of gardens in the achievement of today’s cities to sustainability within the frameworks of the theory of sustainable city. It will also attempt to prove the hypothesis regarding that Dolat Abad garden and the Taj Mahal have established themselves as sustainable elements in the two contemporary cities of Yazd and Agra, and will accordingly continue to remain so.

Following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. However, this concept has originally been developed for American and European neighborhoods’ planning, it could also be customized for other neighborhoods’. Additionally, in the neighborhood scale, the quality parameter factors are more sensible and understandable. Therefore, attention to use these parameters may have better results for neighborhood sustainability concept. This paper claims that if subjective indicators that customized with local context and derived from residents’ perception about sustainable neighborhood are being used, significant differences between residents’ valuing on subjective criteria of sustainability from one neighborhood to another would be found. For this claim, the paper has studied the two neighborhoods of Tehran, as a metropolis with different socio-economic and socio-cultural diversity in its neighborhoods. The findings show that the resulted criteria in the neighborhoods of Tehran, in comparison to each other, have meaningful differences.

Effects of neglecting climatic patterns in buildings are more intense in severe climates such as tropical. It is resulting an excessive consumption of fossil fuels and consequently environmental pollutions in and after modern era. The objective of this research is to find climate-oriented intentions and solutions in tropical areas and compare them with Dezful and Bandar-e-Lenge vernacular houses to exامینe how differences in mesoclimates may affect the climatic pattern of buildings. The present study will initially classify the experts’ viewpoints on the architectural patterns in tropical climates and prevailing targets, solutions, and will present features of the architecture in such regions. The solutions are tested on vernacular buildings of Bandar-e-Lenge and Dezful. The findings demonstrate that in the above areas, climatic solutions have been used to moderate high temperature and humidity. The local houses in Bandar-e-Lenge are in accordance with both climatic objectives but the houses in Dezful pertain solutions for only high temperature. Results also confirm that the difference can be observed because of the different sub climatic groups they are placed in.

Integration and coherence within a city’s physical structure have become an issue for towns and cities as they rapidly expand, incorporate new elements, and undergo incessant changes. At present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. Here, we will be discussing whether it would be feasible to create a system of domestic signs which would reflect domestic social values and mental images held and entertained by citizens, and thus to re-create the sign system of cities. We will also discuss factors involved in interpretation of signs and symbols within a city structure. To prevent emergence or exacerbation of contradiction and disunity within syntagmatic urban structures which have been formed through centuries, we must acquire the knowledge and skill necessary to contain the newly adopted elements and assimilate them into a meaningful and coherent whole. In line with this goal, we have conducted a study of changes of physical structures of the city of Yazd through time (a diachronic analysis) with the aim of identifying sustainable parts of the city’s sign system and with an emphasis on the extent in which it has been formed. The questions which were the motivations behind this work and which we will be trying to answer are: Can the sign system within a city be used as a means for creating an alternative structure within the city’s physicality? Is the sign system (as a tool) characterized by specific patterns on whose identification the coherence of the physical structure of a city depends? How can we achieve an appropriate paradigm within an urban sign system? Here we will try to identify processes of integration of modern urban structures into a city structure, and we will do it through combining views held by semiologists with the ideas of urban incongruity and contradiction, which arise as a result of introduction of modern structures into old cities. To transform the medley into a coherent entity, we need to be aware that cities possess markedness. To this end, we have employed the structuralist analytical method with an emphasis on identification of syntagmatic structures (identifying the structural elements and their relative positions within a city) and of paradigmatic patterns (the ways in which elements substitute for or replace one another). Our main aim here is to extend the scope of studies of urban semiology and introduce analytical tools including the use of structuralism theory in the analysis of urban patterns. We have conducted an in-depth analysis of subjective and objective causes of appearance of signs within cities. We have then conducted case discussions as well as discussions about backgrounds and have tried to establish past and current trends of these signs and symbols in Yazd. Extended data were analyzed based on theoretical notions, paradigms and principles governing systems of signs and symbols have been sought.
