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.
