Regarding the key theme of the paper, visual privacy, it is first necessary to review the content of urban studies to find out why/how has privacy been discussed or ignored in urban studies to date. Instead of direct reference to the privacy, the urban studies literature mainly highlights the concepts of territoriality and personal space, two ways in which people create different types of boundaries to regulate their interaction with others in their environment. These two implicitly define the concept of privacy as both have acquired spatial and social dimensions. Alongside these two concepts which were mainly borrowed from behavioral studies, there are some references to the concepts of privacy and community together in urban studies as well. In line with these, privacy is more concerned with private domain or intimate sphere and community with public one. Thus, the way of their organization and relationship spatially can affect the level of privacy which is culturally specific. Within the urban studies reference books the privacy is still with the concept of territoriality and it has not been defined as a specific concept with separate explanation. Therefore, review of the urban and architectural studies shows that there is a lack of direct reference to the visual privacy. This is mainly due to the nature of built environment, especially the interface between the private and public sphere. In western culture, changes since the eighteenth century onwards has diminished private sphere as the institution of the family loses monopoly control over its privatized domain and ensured access to the public sphere, thus, the dichotomy of public and private space was mitigated. For this reason, direct reference to the concept of privacy which is more concerned with private domain has been ignored in urban and architectural studies in western culture. On the contrary, within the urban context of eastern culture especially those of the Muslim world the privacy is an utmost concern due to the nature of life was contextualized based on the Islamic law. Based on the holy Koran, as the main source of the Islamic law, the private domain has acquired prime importance because the family unit was recognized as the base of entire socio-cultural structure and a self-sustaining institution which ensures ideological and cultural stability over the entire spectrum of society. For this reason, there are many writings which directly deal with privacy and its effects on the urban form of the settlements within the scope of Islamic cities. The important of this concept was such that it was recognized as a fundamental formula controlling the physical organization of the Islamic city as it also led to the premises of development from interior to exterior. It is evident from this review that the concept of privacy is a ritualized and societal concept which has had a great influence on the urban form of the Islamic cities. Its diffusion throughout Islamic lands and its continuity from the pre-Islamic era made it a timeless and placeless concept transmittable to successive generations. Therefore, we can point out that, the core shaping forces underlying the Islamic cities are based upon the concept of privacy and its ground rules (internalized structure based on constraints and thresholds), which emanated from Islamic law. This defined a particular urban form in all Islamic lands which differs greatly from that referred to as the Western model. Therefore, in contrast to the thinking of some orientalist scholars, we can recognize that Islamic settlements are neither fortuitous nor amorphous in their organization, but they are expressions responding to patterns of social intercourse and allegiance particular to Islamic society and its natural context. The logical consequence of the concept of privacy and its relevance to the selected context concerns the way this concept and its relevant features determine the organization of space. It mostly contextualized a kind of layout to protect women from the eyes of strangers and to create clear distinctions and hierarchical spaces to highlight the role and the character of women in the building of the Islamic cities.

One of the valuable arts in the Iranian Islamic architecture was Girih which has showcased the beauty of the Iranian art by relying on a unique and unprecedented geometry. The generative nature of such an art coupled with granting style to the woodworks through taking advantage of elegant colorful glass and the use of geometrical carvings has been perfected during the course of history.

Girih are lines (strap work) which decorate the tiles. The tiles are used to form Girih patterns, from the Persian word, meaning "knot". In most cases, only the Girih (and other minor decorations like flowers) are visible rather than the boundaries of the tiles themselves. Girih are elaborate interlacing patterns formed of five standardized shapes. The style is used in Persian Islamic architecture and also in decorative woodwork, it could be applied either as lattice frames, left plain or inset with panels such as of colored glass; or as mosaic panels used to decorate walls and ceilings, whether sacred or secular. In architecture, Girih forms decorative interlaced strap work surfaces from the 15th century to the 20th century. Most designs are based on a partially hidden geometric grid which provides a regular array of points While there are various materials regarding the aesthetic aspects and the incorporeal and theosophical origin of such art as Girih but it seems that the climatic dimensions has been less dealt with. In the present study, there is proposed this presumption that the Girih is not merely an ornamental furnishing art and that it is in a functional interaction with day lighting meanwhile avoiding vanity and uselessness in its architecture and also that it takes advantage of masonry proportionate to the regional climate through its adoption of a vernacular approach. Thus, it looks necessary to find an answer to the question that “whether the Girih used in the buildings constructed based on the Islamic architecture designs can be defined in fields with climatic functions?”

Another question which can be set forth here is that “whether the Iranian architect has been successful in taking advantage of Girih works in realizing and deploying masonries, and making use of the daylight and natural ventilation?” To answer the mentioned questions, there is made use of the qualitative research strategies and the subjective information and data have been categorized in terms of the content they bear through exploiting rational reasoning via performing library studies in order to be able to extract the effective functional factors related to the Girih work from the background literature and then, in the next step, select the main target samples encompassing the residential homes from Qajar era (1-Forugh-Al molk, 2-Asadollah Shojaat Asad, 3-Akbar Javanmardi, 4-Parviz Amooee, 5-Jalal Sahebolamr, 6-Habibi Pishehvari, 7-Hossein Ali Tasmim Haghighi, 8-Dabagh Manesh, 9-Seyyed Mahmood Fateminejad, 10-Aliakbar Asgharzadeh).

In order to be able to evaluate and assess the case samples and finally the Girih application frequency in the case samples and the type of their application can be obtained through making use of various sampling methods.

Related to case studies and comparing them to documents wood and glass is the most useful materials in Girih structure.

After finding documents about quantity of Girih in each case study authors started to explore the Girih area into façade area which showcased by “f”. As authors mentioned “f” is made by dividing Girih area (Ag) multiplied by Girih numbers (Ng) in each façade side into window area (Aw) multiplied numbers of each window (Nw).

The study findings indicated that there exists a significant difference between the Girih frequency distribution rates along the western side in respect to the other fronts which concomitantly accompanied by the use of a pier’s vertical parasol the same as a similar configuration in the modern climatic radiation protection system provide for the unfavorable western side light effective control.

The absence of the Girih along the southern side is due to the need for making complete use of the sun light and radiation in this front because the interior spaces situated along this side of the house were used during the winters. The use of the vernacular or the regional climate-compliant masonries in Girih provides for the walls’ thermal control and the non-accumulation of the thermal and heat load along the western side.

The traditional Iranian bazaar is considered as a great example of Iranian art and architecture with a rich cultural heritage. This phenomenon of outstanding architecture, self-sustaining and coherent with the surrounding urban landscape, like other urban texture, has not been immune from the consequences of the transformation of modern life in its internal and peripheral arena. On the other hand, the transformation and creation of new structures for the survival of life of historical textures is essential. The concept of contextualism and its purpose in the historical context, based on the qualitative concepts of the creation of a living, coherent and dynamic, is based on the need to recognize and emphasize the extraction of the texture pattern language for structural and functional cohesion in peripheral development. The aim of this study was to investigate the effect of the degree of coherence of new structures on the continuation of the traditional texture life of the traditional bazaar in order to analyze the heterogeneity of infill buildings in the historical context of the Iranian-Islamic city and criticize the existing context, first, with a descriptive-analytical method, on traditional Ardabil bazaar as a case study. Then, in order to answer the question of the extent of the infill coherence effect as a context-oriented parameter on the continuity of the pattern language as a characteristic of context survival, field survey, as well as the questionnaire as a tool for collecting information and SPSS software as an analysis tool, and data evaluation were used. By developing the hypothesis that there is a significant relationship between the amount of context-oriented contemporary infills and the survival of the traditional bazaar context, the research begins qualitatively and to test, the continuation of the traditional bazaar is dependent variable and the degree of contextualism between the infills is the independent variable. First, qualitative studies are conducted based on deductive reasoning and field studies, and then the results are quantified by presenting a questionnaire and examining the views of the resident business people who have at least two generations of bazaar presence, as well as those of contemporary merchants and experts.
The findings in the first section show that the powerful functional-physical centersare of scale that create the pattern of the life of different structures. In the case of the traditional Ardebil bazaar,it is in accordance with the three macro, middle and macro scales, indicate the highest quality of life and it brings forth the semantic coherence of the unified and dynamic Islamic worldview in the structure of the traditional bazaar. The findings in the second part indicate a general lack of coherence between contemporary infills in the 2 nd grade zone of the traditional Ardebil bazaar. Also,it shows that   structural integrity, visual coherence and spatial integrity variables have a direct and significant effect on the dependent variable of the physical life of the traditional bazaar ,and  the activity coherence variable and the cognitive integration of the new building as a predictor variable on the functional life of the traditional bazaart. Therefore, dealing with concepts such as scaling and scale distribution, necessity to go beyond the strictly limited use of the brick and the limited height of the building and the window frame in the traditional bazaar becomes vital to consider, so that deep concepts of the language of the texture pattern can be continued and the new recommendations for design identity in the historical context can be created for designers to emphasize "modeling" rather than "formalism".

Space as an essential and integral concept of architecture has always included different meanings and understandings, and this reduced its original meaning to general architectural features. In addition, because this concept was created in the modern period, architects’ general understanding of its indicators has unilaterally been led to the concepts such as void, freedom and movement. Therefore, there has not been any true and comprehensive understanding to evaluate the indicators directly related to this concept. On the other hand, in Iranian-Islamic Architecture, space as the main element making form of the buildings has been considered much more than the material aspects, but due to the lack of a specific framework for explaining its physical indicators or modern sense of space, it has not properly been analyzed. The main purpose of this paper was to identify the principal indicators related to the concept of space and examine the relations, and this was achieved through purposeful analysis of basic definitions, Western viewpoints of architectural space, and perspectives of Iranian-Islamic architectural space. The paradigm of this study was qualitative and the methodology was based on documentary and library researches. In order to achieve a conceptual framework for analyzing the essential indicators of space in architectural works they were distinguished from general features and other concepts through analyzing and comparing of important perspectives and organizing existing structure in recognition of space. Finally, based on this model, the overall status of the indicators of space in Iranian-Islamic architecture and important periods of Western architecture were compared. An examination of architectural space indicators based on Western theories revealed three types of viewpoints: 1- According to this view, architecture was considered as the “Art of Space” which has been on the path of historical evolution, and always conformed to “dematerialization” (reducing the effect of the masses) and increasing the role of empty spaces. Clearly, on this view, the indicators were emphasized those which conformed to “total freedom of space”, “exposure”, “permanent expansion”, and “maximum relation”. 2- This thinking was almost the opposite of the first point of view. The theorists criticized the unlimited freedom of the space and looked for defining the new intricate and meaningful structures. It could be said that this view, influenced by phenomenological approaches, conformed to promote the concept of space to “place”, caused to the sense of habitation and settlement, and emphasized the “internalization” and “preservation” as the main characteristics of the space. 3- In this view, the relative balance among the dual indicators of architectural space and their challenges were emphasized. Accordingly, fundamental characteristics of the architectural space in different periods were identified with no specific direction to one side of dual indicators. In fact, the balance between the inside and the outside was necessary. It meant that in order for space to be essentially recognized as real space, at least a part of this separation was needed. On the other hand, the complete separation was not usually correct too. The enclosure and protection of the inner space and the continuity between the inside and the outside both were inherently necessary and appeared differently depending on the period of each architectural work and its context.
Iranian-Islamic views on the space were investigated both in art and architecture. In Iranian-Islamic art theories, two facts were revealed: 1- The emergence of imaginary and mysterious quality through the constant fluctuation between opposing characteristic and creation of dual concepts such as “Hayaa” (modesty). 2- The balance between material and immaterial aspects in art to achieve two main goals: the existence of art and a trace or an echo of God. By reviewing the opinions of some experts in Iranian-Islamic architecture, such as Nader Ardalan, Darab Diba, Seyyed Hadi Mirmiran, Mohammad Reza Haeri, etc., it became clear that the dual indicators of space appeared in two different ways: In the first case, there was simultaneous presence of opposing dualities, such as void-mass, inside-outside, movement-stagnation, continuity-obstruction of vision, etc., and at the same time, the tendency to internal and limiting indicators. In the second, there was simultaneous presence of opposing dualities and the lack of inclination to one side: balance, ambiguity or fluctuation in dual indicators. The results of numerous analyzes indicated that, despite of intricate and extensive theories of architectural space and approaches derived from, they revealed certain forms of relations between the dual indicators in a “spectral” framework. These indicators both at the basic level (fundamental indicators) and at the final model (extension of basic indicators) showed different tendencies, including the overcoming of liberating characteristics, overcoming of limiting characteristics, and the balance or fluctuation between the dualities. In a general comparison, it could be said that the indicators of the space in Iranian-Islamic architecture appeared balanced, vague, or mysterious, which had some similarities with spatial concepts prevailed in Postmodern architecture; and they were completely distinct from those of other periods of Western architecture.

When architecture is discussed in the land of Iran, architecture is created as a container and context of life for human beings where the Spirit of God is blown in his (her) (Surah Al-Hijr - Verse 29), his existence is not limited to material needs, but he is a creature with different existential levels. It derives from the material needs such as eating and sleeping, and need for shelter, which arise from the material levels of human existence to the psychological needs that embrace a range of needs from security to belonging and levels of spirituality of human existence with its characteristics and needs in which the essence and basic instinct of humans lies. Iran is a country with long-standing architectural value. Experts have long a consensus on the preservation, restoration and rehabilitation of Iran’s past values to preserve cultural values representing the national identity. Identification of the past noble values and adopting the most important one in observing criteria in accordance with the circumstances of time and place of today's society is considered the main problem. In this regard, we should try to recognize the Iranian - Islamic architectural values and reflect them to young professionals who are somehow involved in this issue. Today, it is tried to convey ideas and thoughts to others in the form of desired concepts and ideas using the meaning language which is indirect.
In the meantime, valuable Iranian Islamic architecture, due to its comprehensive functionality as well as permanent and enduring presence in our culture, is considered more than before. Because maintaining Iranian – Islamic values and identity is one of the requirements, modern designers are obliged to think deeply about traditional architectural values and standards to get rid of the imitation and create a design in accordance with modern human expectations based on Islamic law. In this regard, architecture, due to direct contact with human life, plays an important role in strengthening or weakening culture and identity in the face of globalization, for all the people are associated with the architecture and their behaviors are shaped in these buildings. The importance and necessity of this issue, in challenging designers to think about the different aspects of the past architecture and special attention to the ancient fundamental values, is to enrich the design quality. The study has a qualitative and quantitative research method, because it used desk and field study to gather information. Its qualitative nature was created with research studies and literature review and its quantitative nature was shaped by choosing statistical population and preparing a questionnaire for the analysis. 
The identification of the past architectural values and selecting the most essential of them are considered as the main issue in the observance of the scales matching with the temporal and spatial conditions of the today’s society. Efforts have to be constantly made for recognizing the Iranian-Islamic architectural values and reflecting them to the young experts who are somehow involved in this issue. The present piece of writing has been compiled based on a qualitative and quantitative method and the study has been conducted based on a survey method; the study is fundamental in terms of objectives. It is posited based on the selection of a process of the qualitative-descriptive type and its investigation based on a quantitative method that “there is observed a significant relationship between meaning and contextual elements of architecture”. It might have been quite common in the past architecture, especially in the Islamic Era’s architecture, that the manifestations and embodiments of the concepts stemming from the society’s culture were manifested most beautifully in the architectural works hence more readily identifiable. Moreover, the principles that are dealt with in the resources are different in terms of prioritization and valuation; thus, experts’ notions have been used in this area to quantitatively discover these topics using survey methods. At first, in order to achieve sublimity in architecture through seeking assistance from the honorable Surah Hashr, ĀYA 23, and comparing it with the valuable architectural principles, it has been descriptively investigated and extracted and 15 professors were subsequently asked to confirm this information. Next, a questionnaire was codified and, in order to select a study sample volume comprised of the experts, including the professors and students of post-graduate education in state and national universities of the country, five universities were selected that included 120 individuals in total and, excluding the imperfect questionnaires, 100 questionnaires were finally attained. The data were analyzed in SPSS software, version 21, using statistical tests (one-sample t-test, two-sample test, ANOVA test and Friedman test); the results have been offered in two descriptive and inferential methods. The results indicate that there is a significant relationship between the indicators of the concepts and the contextual elements in architectures. Furthermore, factors like semantic, climatic, structural and eventually technological indicators were respectively found with the highest degree of importance.

In this study emptiness is considered as a transcendental and effective concept that appears in the form and content of things. What is seen as internally present in an entity is existent in the first instance because of the external presence of its opposite. The entity and its opposite are intertwined through the principle of inverse correspondence, a higher level of accord that emerges from the disposition of asymmetrical qualities. this symmetrical, yet reversed, reciprocity is the logic of ‘‘is and yet is not’’ and that of ‘‘simultaneity, and biconditionality, of opposites without their higher synthesis.
Emptiness is often understood as nonexistence, a void that is symptomatic of a predominant fixation on objects. In contrast emptiness is neither nothing nor the suffocating void of limitless expansion in which things are at best desolately scattered. Rather, it is the ultimate foundation of reality that transcends ideas of ‘‘being’’ and ‘‘non-being.’’ Subsequently, what is operating in emptiness is a double negation: the negation of being, which leads to nonbeing, and the negation of nonbeing.  Existential Identity depends on the dialectical relationship of that thing with its opposites. The identity of a being is determined not by what is believed to be existent within itself but by its dialectical relationship with the opposite, like the moment in which one finds one’s self to be the being of warmth in reference to coldness enveloping and penetrating the body.
Ignoring Emptiness and empty space caused intensifying the focus of designers and architects on the full space and this has increased the contemporary architecture crisis. this study aims to take advantage of the values of the vernacular architecture of Iran and its continuity. It relies on the theory of empty space and the opposite pairs, as the first pillar of creating empty space. Answers to this question: what is the role of empty space in the vernacular Yazd houses in semantic dimension?
 This study aimed to clarify the role of this concept in the vernacular architecture of Iran by understanding the meaning of emptiness. and evaluating selected houses as a case study. This research has been done in qualitative research and data is collected by observation and study of written documents.
The emergence of empty concept coincides with two elements or opposite qualities in such a way that the two opposites are interconnected without diminishing one another. Based on theoretical findings, the expression of the empty concept is conditional on the existence of three pillars: The first: the contradiction, the second: interaction, the third: balance and unity.
Based on the theoretical findings, expression of emptiness concept has three main pillars. Firstly: the contradiction (Coexistence of two opposing elements), secondly: the interaction of two opposites, thirdly: balance and unity. Since the emptiness operates as the foundational principle in traditional genres of architecture in Asia suchas Iran, the process of integrating the three pillars extracted from theoretical foundations were evaluated and analyzed in five vernacular houses of Yazd. In the phenomenological study of five houses in Yazd as a case study houses were investigated in three aspects: shape - body, functional, semantic. This article focuses on semantic aspect.
The findings depict that the emptiness as a transcendental concept is the result of the process of opposite elements and their interactions and the development of the unity of opposites. According this study, the philosophy of emptiness has manifested in the form of the dialectic of opposites. this study has brought one’s attention to the arrangement of contrasting qualities in the yazd houses such as the crossing and peresence inside and outside.
The architect of an Iranian traditional house positions things of spiritual character in such a way that they create a coordinated balance between forces. In this fashion, the house ‘‘brings into special focus the underlying relatedness of things, the mutuality which exists in spite of differences between outside and inside, great and small, and observer and observed.
Vernacular architects had understood the necessity of companionship of opposing pairs and their dialectical as an essential element of empty concept. They have considered interactive opposite qualities such as darkness and light, outside and inside, male and female, silence and talk, simplicity and complexity, uniformityand variety. The results of the research show that empty space plays a major role in the vernacular architecture of Iran. The empty spaces are more focused and authentic and solid spaces take their identity and credit from empty and void spaces.

Satisfaction with housing and residential environment is one of the aspects of life satisfaction. The relationship between solitude in personal spaces and collective interaction in the spatial organization of an apartment residential unit is one of the determining factors of the components affecting residents' satisfaction. Providing privacy for family members in the physical space of the residential unit is a foundation and a prerequisite for maintaining privacy and regulating internal relations and communication with the outside of the residential unit. The research question is, what is the relationship between spaces in the types of spatial organization of apartment residential units? What is the effect of the relationship between personal and collective spaces and inter-spaces of the residential unit on the level of satisfaction of the residents? And how can this satisfaction be improved with design solutions? The main goal of the research is to raise awareness for better design of apartment residential units. Other goals of the research can be to better understand the human relationship between the elements of the spatial organization of the residential unit, how to create a platform for individual privacy and collective communication between family members and guests, creating auditory and visual privacy in the interior of the residential unit and overlooking the neighboring units. The above research has benefited from residents to collect data and complete the questionnaire. The case study is limited to the common apartment housing of Amel city (row sets with medium height in three to six floors with spaces such as entrance, connecting stairs, open space and other common structural and facility elements). In these buildings, based on the study of the thesis documents registered in the central municipality of Amel, four types of residential units have been identified, whose spatial organization is the most frequent. The findings of the research show that the residents of apartment residential units have expressed relative dissatisfaction with the lack of necessary provisions in observing the transmission of sight and sound between the internal spaces, observing the necessary distance between the collective and personal spaces, the view from the entrance part of the unit and the openings of the facade to the internal spaces. The result of the research is to propose solutions for entrance design, geometry and plan fit, controlling sound transmission between the spaces of the residential unit, controlling the view from outside the unit and creating a useful space for pause and movement in the spaces between the two main parts of the unit. The research results can be generalized to similar cultures and cities in the north of the country. The table of research design solutions can be adjusted according to the cultural-climatic conditions of other regions of the country in order to develop design guides that are suitable for local cultures and special environments.
