Open spaces in historic cities of Iran, apart from their specific uses, have had special urban roles and organized the adjacent routes, buildings, and urban fabric. These spaces underwent numerous changes due to urban development and not only lost their functional roles, but also turned into urban problems in some cases. on the other hand, the lack of compiled studies and accurate documentation of these sites has made their preservation a serious challenge. This study uses descriptive-analytical and descriptive-historical methods in order to to present a standard model for the documentation of urban open spaces based on international guidelines (Sofia Charter 1996). to achieve that, open spaces in the historic city of Kerman, and specifically pamanar neighborhood have been studied and documented in this paper. . . It should be noted that many of these spaces have not yet been properly studied and have experienced many changes which makes their documentation necessary. The result of this study is a template based on an authentic international guideline that can be used to document urban open spaces. By using this template, scattered and unfounded studies are avoided. Moreover, the provided standard template can adapt to different conditions and facilitates information management in the preservation of historical fabric.

The topic of architectural stylistics in Iran has always been one of the challenging debates in scientific societies. Although stylistics is important in the field of the art and architecture, there is no clear consensus among scholars on the extent and variety of its definitions and functions. In Iran, although it has been around for half a century since the concept has entered the scientific discourses in field of architecture, but its definitions and function have not yet been formulated. The history of stylistics research indicates that stylistics has various functions as an approach to the study of architectural historyone of the most important of which is a classification method in architectural history. Its feasibility and versatility in terms of its ability to cover several approaches to different aspects of architecture in its operational definition and ultimately its flexibility in operating according to the purpose of stylistics, makes it a suitable approach. This paper attempts to explain the concept of architectural stylistics and propose a new approach to architectural conservation and restoration, based on the principles of stylistic studies. For this purpose, first the types and characteristics of research methods in the field of architecture are identified and after identifying the type of research problem, its genealogy has been determined based on the purpose and gender of the problem in order to select the appropriate method and approach. The research method of this article is content analysis with theoretical and operational definitions of stylistics. At the end, the stylistic position of Iranian architecture was explained by analyzing the project of Mohammad Karim Pirnia, and the position of stylistics in the field of architectural conservation and restoration has been explained, which challenges existing perspectives and leads to the details of the proposed definition. The article search system is qualitative and, along with semantic interpretation and analysis of data, seeks to define a suitable and applicable approach to Iranian architectural stylistics. The research strategy is interpretive. This is a theoretical and applied research.

The Safavid period is regarded as one of the leading periods in the field of architecture of religious tombs and, consequently, the area of Isfahan in this period as the capital of the state completely reflects the architecture of this era. The purpose of the present study is to identify and categorize the physical-spatial characteristics of the species of this type of architecture which, given the neglect of existing works and consequently their gradual destruction, seems necessary. this study aims to answer the following questions: what are the physical-spatial characteristics of religious tombs and how to assign weighted values to each of these characteristics. in this regard, firstthe burial features were identified based on Islamic teachings and tomb architecture principles, and then 17 tombs were identified in the Safavid Isfahan and its affiliated territories andclassified into tombs of Ulema and imams’ offsprings based on the deceased’ s religious rank and their principles. and their physical-spatial principles and features were analyzed separately by descriptive-analytic method. Finally, by putting together the analyses of each sample, the statistically significant results of the dominant features on the tomb architecture of the Safavid period were obtained in each of the components discussed and in each of the two types examined and presented. Of these, some features common to both species in question, include the extraversion and observance of particular hierarchies of entry into the tombs and the centralized geometry of their predominant main space.

Windcatchers in Yazd are a prominent example of energy saving through building design in hot-arid climates. Therefore, careful quantitative and numeric study of their performance and behavior can be beneficial towards achieving climate-friendly solutions. this research is carried out based on field studies and long-term measurement of climatic factors in a traditional windcatcher in Yazd. In this study the results of long-term measurements of wind flows around and inside the windcatcher of Mortaz house as a sample in Yazd’ s historical fabric are presented to examine its performance in utilizing wind energy. A local station for extracting micro-climatic data from the study region was installed and the windcatcher was equipped with devices and censors for climate data measurement. comparing the velocity profiles for the outward airflow of the windcatcher and the local wind flow in hottest and coldest days of the year indicated a higher conformity between the abovementioned airflows in the cooling period (hot days of the year). Furthermore, the higher velocity of winds in summer compared to winter in the region which causes increased airflow inside the windcatcher during the cooling season also indicates better performance during the cooling season compared to the heating season (cold days of the year). This also applies to ventilation during the night. Physical properties of the windcatcher were also compared with local climatic conditions. The orientation of the windcatcher allows it to receive 80% of dominant wind flows during summer, among which 48% are desired wind flows. therefore the goal of this paper is to present the pattern of wind behavior in the studied windcatcher in order to examine its conformity with local climatic conditions.

The city of Qom is considered a high risk area due to its high seismic risk and high vulnerability. The large population at risk on the one hand, and the lack of a suitable plan to accommodate the large population based on recent earthquake experiences and actions, on the other hand, exacerbate the situation and turn it into a crisis. The purpose of this study was to derive a suitable model for temporary accommodation after a possible earthquake in Qom. According to this model, the design of the temporary accommodation required is based on the physical and non-physical conditions of the site, using existing potentials and infrastructures. A criterion can be used both to design and provide the right solution in times of crisis and to help evaluate and compare designs and design competitions for a uniform evaluation. In this research, a quantitative-qualitative research method with descriptive-analytical approach along with field surveys wereused. Library study tools, document review, observation, and interviewing with authorities and experts have also been used to collect information. The result of this study is to present a model of temporary accommodation after a possible Qom earthquake based on the design criteria for temporary accommodation. In this regard, temporary housing design criteria were extracted based on specialized literature review and similar experiences and prioritized and weighted by the Analytic Hierarchy Process (AHP). Subsequently, housing options in the city of Qom were prioritized according to design criteria. In the end, by combining these options, the temporary housing pattern of Qom was determined. To facilitate understanding of how this pattern was transformed into a physical design, an example was designed with attention to architectural details.

The purpose of this paper is to understand the conceptual domain of “ maidan” (the Persian square) and the range of it’ s instances in Qajar Iran based on historical maps. Modern mapping in Iran began in the Qajar period and resulted in producing accurate maps with unprecedented detail of Iran’ s cities. These maps are great sources to understand the elements of the city in this period of time because they illustrate each element within the network of the interconnected elements which shapes a city. Maidan, as one of the main elements of Qajar city, has an important role in many of these maps, which makes these maps valuable sources for exploring the concept of maidan in Qajar Iran. There are almost thirty historical maps of cities in Qajar Iran and maidan can be found in 21 of them. These maps are potentially great sources for understanding firstly, the conceptual domain of this concept and secondly, the different types of its instances. To do so, we identify the different instances of maidan in these maps, study their forms and characteristics, and interpret their roles and function in the network of the city elements. Moreover, to develop and deepen these findings, we refer to the primary and secondary written sources and historical photos that can help. In this survey, firstly, we illuminate the conceptual domain of maidan and try to describe its meaning; Then, based on the high frequency and prominent characteristics of the instances, we explain the main types of maidan in this period of time. So, based on historical maps and helped by other sources, we interpret the concept of maidan in its socio-historical context by using the Interpretive historical research method. The results of this research, first, show the extensive and flexible field of the concept of maidan in Qajar Iran and let us redefine it: every open and unroofed space in a city which includes a distinguishable area and provide an opportunity for activities or events. Second, they describe the main types of maidan in four categories: royal maidans, maidans of the bazaar, maidans of Neighborhoods, maidan of the parliament.

Khavunchini is a kind of extruded ornamental brick work, using brick pieces of equal thickness and different sizes and is applied as the facade of the building. These types of ornaments are found in the vernacular architecture of Khuzestan province and have been used extensively, especially in the historical part of Dezful, in entrances and parts of the inner courtyards. The motive for the present study was studying the shading effect of these patterns on the building facade. the shadow produced by Khavunchini, especially in summer, covered a considerable area of the facade. in addition to their aesthetic role, the resulting shadow patterns can be effective in reducing heat transfer from facade in summer, in very hot climate of Khuzestan. The research objective is to test the effect of these elements on heat transfer from the facade surface. In this study, with an experimental approach, two identical cubicles were constructed with the south face of brick wall, one with a Khavunchini pattern on it and the other with the same but not extruded pattern. Due to the abundance of these ornamental elements in the Dezful historical part, the desired pattern was selected from this region. Abadan was selected, as the representative of very hot and semi-arid climate of Khuzestan, for constructing the models. The reasons for this choice were the feasibility of building the models and conducting experiments in Abadan and the climatic resemblance to Dezful as a treasure trove of Khavunchini art. The variables of ambient temperature and relative humidity, temperature and relative humidity inside the cubicles and average temperature of the cubicles' south face inner surface were recorded in six measurement periods in summer 2019. the results showed that, at the hottest hours of the day, the average temperature of the south face inner surface and the indoor temperature of the cubicle with Khavunchini compared to the cubicle without it, showed an average decrease by 1 and 0. 8 ° C respectively. The results confirmed the positive effect of Khavunchini on heat transfer reduction from the south facade in summer in the studied climate.

Religious buildings from prehistoric times to the present have played an important role in the formation of the constructional elements of cities, settlements and even villages. According to archaeological excavations and historical evidence, temples and religious sites in pre-Islamic times have always been one of the focal points of people's gatherings for religious ceremonies. Isfahan province is one of the most important historical areas of the country throughout the period in which many buildings remain unknown. One of the most important monuments in the city of Isfahan is the Haft-shoyeh Jame mosque located in the northeast of Isfahan (Ghahab area). Considering the multi-period architecture of this building, its lack of introduction and multiple construction periods and the lack of inscriptions on the construction date, a comprehensive and independent research seems necessary. Therefore, the present research is trying to introduce and identify the historical and physical classification of Haft-shoyeh Jame mosque based on historical evidence, archeology, architecture and comparative studies. The results show that the Haft-shoyeh Jame mosque was one of the most important mosques in the northeast of Isfahan in the middle Ages, with many historians referring to the mosque and its heyday during the Seljuk period. additionally, the two important Seljuk and Ilkhanid periods can be identified in the construction of the Haft-shoyeh Jame mosque by the type of map and a material used in it, although additions from the Timurid period are also identified. The methods used in the present study include descriptive-analytic, historical and comparative methods. In addition to the written legacy of the writers including historians, travelers, and researchers who have investigated the field, field activities on site including historical-physical examination of the building and its architecture, photo preparation, planning, three-dimensional design and comparative comparisons with similar exampleshave been Performed.

Uncontrolled consumption of Energy and fossil fuels has led to the loss of resources and environmental pollution. Therefore being Consistent with natural conditions through architecture is essential. nature has always been a source of solutions for designers. The biophilic approach is a design approach based on belief in the effects of nature on the psyche and life. The green roof and surfaces, sky garden and green courtyards are design solutions based on this approach. The climate of Kerman is hot and dry and therefore it is necessary to consume a lot of energy. Depending on the vegetation features, green space can be used to assist in passive cooling and heating of the building. Increasing population growth requires energy supply and a lack of green space in Kerman has made the use of the green wall necessary. Here are three solutions, direct implementation of the plant on the facade, indirect vegetation and live wall. It is assumed that the biophilic approach can provide valid design options as a climatic solution to reduce energy loss. The purpose of this study is to investigate the effect of plant use on the vertical faces of buildings in hot-aridclimate of Kerman. In this study, the effect of green wall on reducing energy consumption and increasing thermal comfort is investigated. The research method in this paper is based on a combination of quasi-experimental and simulation methods. For this purpose, empirically made green wall samples with real scale have been investigated by temperature and humidity measuring instruments. The field results have been compared with the help of the software. According to comparison of the outputs of the software and the field data, the best temperature and humidity performance with substantial difference belongs to the the live wall, followed by the indirect green wall and the reference wall, respectively. Also the living wall provided the highest amount of moisture in the interior.

The houses are the nearest spaces related to human. The changes in Iranian lifestyle have resulted in a change in modern houses architecture. Iranian traditional houses sound to have the characteristics which can keep alive the sense of place in people and transfer the space soul from the past days to the present. This vital point can be the main part of vernacular design solutions for villas in Iran. therefore the following questions arise: what are the components that create sense of belonging in Iranian houses? And which one of those needs to be recreated or rethought and which one preserved? Research method in this project was practical and due to it’ s hybrid nature, included both library methods with a focus on analysis of sense of belonging and case studies through observation of traditional houses, Atrvash and Mohtasham in Shiraz as well as Masudi and Akhar-e Hafte villa. Then, the analysis through computer simulation (Depth Map) was examined in order to study spatial arrangements in both modern and traditional modes and compare the collected data and obtain vernacular methods to design modern villas. The pros and cons of each sample in achieving the influencing factors of sense of place were identified and the influencing physical factors of sense of place were extracted using logical reasoning which led to two physical characteristics of IEQ (flexibility) and comfort. analysis of simulations on samples demonstrated the elements such as entrance corridors and corridors leading to rooms and vestibule have been removed in modern houses which has caused deficiency of spaces in creating spatial hierarchy and privacy. On the other hand, the places like private rooms that were not often personal have been reintroduced in modern houses that has increased the respect to the privacy of family members and has created a place for working at home. Finally, it can be mentioned that Iranian house architecture can raise the level of sense of place for inhabitants by using the model of traditional houses and recreating central courtyard, vestibule and increasing efficient intermediate spaces.

Due to the special geographic conditions and hot and dry climate of the central plateau of Iran, the design and construction of climate-friendly buildings and urban spaces in these regions, requires receiving minimum energy in hot months through appropriate orientation, decreasing the area of surfaces facing radiation and maximizing the amount of shading on exterior surfaces. The aim of this research is to determine the optimal building orientations in hot-arid climate of the region through surveying the amount of direct radiation energy received by vertical surfaces of buildings in Isfahan, Semnan, Kerman and Yazd cities. At first, the amount of received radiation energy was calculated in theoretical and real way, by using the “ Law of Cosines” computational method. Then based on the minimum temperature of thermal comfort, the amount of energy received by the vertical surfaces was calculated and processed in 24 different geographical directions, separately for cold and hot periods of the year. Finally, based on the minimum energy received during the hot period of the year, the most suitable orientations of vertical surfaces of buildings for one, two and four-sided buildings were determined in studied cities. The research findings show that the best orientation of vertical surfaces for one-sided buildings in Isfahan, Semnan, Kerman and Yazd is 180 degrees South and after that, is 165 degrees SE. Also, the best orientation of vertical surfaces for two-sided buildings in studied cities is (180, 0) and for four-sided buildings is (180, 0, 90,-90) degrees.

Indoor space quality is directly related to the occupants’ physical and mental health (sick building syndrome) and energy saving in the building. Incorporating climatic factors in architectural design can increase occupants’ well being while consuming less energy. Iranian traditional houses have always been good examples of such architecture and provide useful inspirations for contemporary architects. traditional Qajar houses in the historical part of Shiraz city are prominent examples of this high quality architecture, but few studies have been conducted about them. evaluating IEQ factors in these houses specially daylighting and thermal comfort and their influencing factors can be beneficial to contemporary designers. Nemati Qajar house in Shiraz is selected as the case study. with the aforementioned factors have been evaluated using quantitative methods including field surveys and simulation in Designbuilder software. The results of the findings are analyzed in 2 steps: First, the amounts of thermal comfort and daylighting in spaces were compared with current standards. Second, the results were expressed in a qualitative way using architectural specifications of spaces. The findings of this study indicate that the rooms of this old house have different energy behaviors. For example thermal comfort in the basement is in acceptable range for 10 months of the year, but it lacks proper daylighting, and the shaahneshin room is in thermal comfort range for 8 amonths of the year and has proper daylighting for almost all months of the year
