Abstract

It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the degree of accuracy in the calculation mentioned above, the authors suggest a simulation programme that can do the job precisely and accordingly. It seems that, in order to calculate the energy requirements of school buildings in Iran for heating, cooling and lighting, it is better to use a simulation programme, too. In fact, this paper considers details of lighting as part of a comprehensive programme and Iran schools design requirements for lighting. As we will see, this research describes the method of calculation of daylighting, which is used in the part of lighting simulation programme. Effective daylighting design requires consideration of different factors such as daylight factor, luminous efficacy of solar radiation, orientation factor, glass transmittance factor, average reflectance of material and etc. which are need for calculation of exterior and interior luminance. They are discussed in details in this paper.

Abstract

Considering the problems facing contemporary architecture in Iran, a better understanding of the meaning of architecture has become necessary. Architecture, like language, defines and facilitates the relationship between Man and his environment. The word architecture both in Arabic (Amara) and in Latin (Architecture), attempts to define the attributes of the maker before determining the characteristics of the product - a fact that points towards a more profound understanding. Thus, it is becoming increasingly important for researchers to define the process of formation (the how of architecture) more than the specific attributes of built form (the what of architecture). In this way, creativity and the different processes by which it is achieved, would gain a higher significance in architectural circles. Using an Endogenous Development model, this article seeks to offer an alternative approach towards architectural design. Accepting the hierarchy in causal relationships and expanding on the concept of elevating hidden meaning up onto the surfaces of expression, this article proposes a model of thought in which design consists of a process starting at the depth of ideas and common beliefs, moving up to the individuals' images and finally arriving at rational and general concepts. It is then argued that this process provides spaces in which it is possible to experience a sense of belonging to place, and even further, it allows users to abandon material belongings to arrive at feelings that occur in sacred places. This article offers the author's own particular teaching as one expression of this model of thought, whereby students start by working with mud and then gradually leave their childhood status to reach full maturity in design. Through this process, they obtain an ability to overcome technical and rational challenges in their projects, moving from "intuition" towards "wisdom", "knowledge" and finally "science" in the material world.

Abstract

Iran is located in a high-risk seismic zone of earthquakes. It has thousands of valuable historic buildings, mostly made of unreinforced masonry, which is quite vulnerable to natural hazards, especially earthquakes. The conservation and seismic upgrading of these buildings is vital for their survival. However, resources are limited and some sort of prioritization is needed in order to allocate the budget. There are several factors, which should be considered when ranking heritage buildings, but this paper mainly focuses on the values of historic buildings and describes a survey undertaken to find out whether it is possible to rank them. The method applied is choosing a particular group of people and determine whether they can classify buildings into a hierarchy? The results showed that most people could perform this task, so some sort of hierarchy exists, although different groups might choose different hierarchies.

Abstract

The traditional architecture is the achievement of mankind experiences in different geographical/cultural and social domains. The traditional architecture of Iran as a valuable outcome is one of the live and spirited instances of the history of human life that through pondering and research and close relationship with its natural, historical and human environment would be obtained. The repeatability of it contemporarily is somehow difficult so the Iranian architects and urban planners mostly focused their attentions and efforts on preservation and conservation of it. A brief review of such literature provided within this era outlines that mostly current studies and researches focuses on the outcome of such architecture or at most consider the characteristics of their creators and are less surveyed the creation and its process context. The attitude of traditional architect toward designing context or "the place of design" is one of the least considered aspects of traditional architecture. Such attention would lead to noteworthy achievements even in today's attitudes toward design and effective factors. The evolution manner of architecture traditionally which is in place of attention in this paper, provides a method of direct reference of the traditional architect toward the place of design or "earth" even when some written documents of them are not available. To achieve such goal this paper mainly concentrated on the remaining resources. In this respect the historic habitats of Yazd could be mentioned as one of the paragons of "Iranian Traditional Architecture". This paper briefly expresses and points on this fact that the creation of architecture traditionally happened in a totally different existential scheme in compare to modern era that specifically seeks such difference within the attitude and approach toward earth (site) or the place of design. The theories of two notable personalities of contemporary architecture "Christian Nordberg Schultz" and "Christopher Alexander" are considered. This is necessary where as while fulfilling the reliability of the paper and points on some notable similarities within their theories by what's recognizable in Iranian architecture and declares the different fundamental aspects, too. In respect to the subject, part of paper considers the clarification and illumination of traditional architecture.

Abstract

Quality is the most important consequence of an urban design project, and its promotion is the final duty of an urban designer. So "urban design guidelines" which use environmental improvement factors in their structure, have an effective role in promoting urban space quality. "Urban design guidelines" are the most important instruments in urban designers' authority, to reflect and appear improvement plans in urban spaces and create the bridge between research (theoretic studies) and practice (professional efforts). The paper guidelines are generic statements that specify the goals, the design pattern for achieving them and the evidence supporting the linkage between goal and pattern. On the other hand, decisions about how to address the issue of parking are among the most important in making the city center a high-quality place for people. The city center cannot have a pedestrian orientation, a concentrated diversity of uses, or a continuity of street-level activity if parking is not well designed. Attention to varied types of existing parking in city center area (such as on-street parking, surface lots or parking structures), the main idea of this paper is to promote the quality of city center spaces, by using different urban design guidelines.

Abstract

Neighborhoods within the hierarchy of urban structure are one of the smallest socio-physical building blocks of cities. Traditional neighborhoods of Iranian historic cities benefited from strong social relations which were flourished over the years and were manifested in the neighborhoods centers. In the modern era, the new master plans and the complementary local plans have disintegrated these neighborhoods both physically and socially. While old traditional neighborhoods were destroyed and new car oriented streets and highways have disrupted the traditional neighborhood life, the introduction of metro stations have provided a nucleus for neighborhoods around which urban space and social activity could emerge once more. In this respect, the attitudes of residents towards metro stations are very important. This study focuses on the social attitudes and the evaluation of traffic impacts of metro stations on adjacent neighborhoods. Therefore, the changes in traffic patterns as well as social characteristics and residential satisfaction levels in two neighborhoods adjacent to metro stations are studied through a questionnaire survey. The results show that despite the potentials provided, metro stations had adverse affects on both social integration and residential satisfaction levels. They also adversely affected neighborhoods in terms of traffic flow through increase in local traffic, demand for parking, and increase in noise pollution. Lack of attention to the new potentials turned them into threats and weakened the already damaged neighborhood structures.

Abstract

Accessibility is one of the important factors in public open space design and the creation of equitable neighborhoods. Limitations caused by physical disabilities should not be a barrier for accessing desired spaces and people must be able to live with the greatest possible independence regardless of mobility limitations. The purpose of this paper was to identify the inclusive criteria of pedestrian design and explore the physical characteristics of equitable neighborhoods in Iranian cities. People who experience disabilities have equal rights to have access to the physical environment, communication devices and different services for education, recreation, social participation, accommodation, health and employment. This study was based on the analysis of the morphological characteristics of the Iranian traditional towns (Yazd and Nain), the socio-historical information, and the direct observation of the spaces, and interviews. The findings of the research showed that social equity and shaping an inclusive community are among the problems of developing countries. Based on the findings related to physical limitations of people with special needs and their attitude toward the varied problems they face, some key solutions have been proposed to guarantee better independent movement and achieve equity of access. People with disabilities should be equal to others in terms of their access to urban spaces, regardless of gender, ethnicity and type of disability. Safety and convenience are some ways for promoting public health especially its mental aspects. Finally it can be said that inclusive pedestrian networks will provide the people especially those suffering from physical disability and moving limitations with more accessible routes and help them participate in personal and social spheres of life more effectively.

Abstract

  In this paper, authors tackle three very important questions that need to be answered if a theory of design is to be constructed. The first is what designers do, Which we attempt to illustrate with the help of case studies and theories of design practice. The second question is what guides designers. Here, authors try to present some of the proposed normative positions about design, to show the similarities and differences between positions and a framework of how they can be categorized. The main (third) question is how the design thinking process can be represented drawing upon on a review of recent studies of design practice and designer's creativity.

  One approach to design thinking is to extract the features of the designers' strategic knowledge, for which comparative studies between expert designers and novices are useful. Also, controlled experimental studies may be adopted in order to understand the nature of the idea generation process.

Finally, the methods of research and representation of design thinking in order to gain a deeper understanding of the designers' creativity are proposed.

Abstract

When a specific building is examined and analysed for its architectural merits, it is the visible, superficial aspects, which are considered, for example: aesthetics, function, spatial relationships, and landscape. One of the most important invisible factors that should be considered in the design process is the safety of buildings against natural hazards, particularly against earthquakes. While the provision of earthquake resistance is accomplished through structural means, the architectural designs and decisions play a major role in determining the seismic performance of a building. In other words, the seismic design is a shared architectural and engineering responsibility, which stems from the physical relationship between architectural forms and structural systems. It is economic to incorporate earthquake resistance in the stage of design than to add it later in the structural calculation or strengthening after completion. In addition, a building with proper earthquake-proof design will be more effective against earthquakes than the one with complementary strengthening. This paper will demonstrate that evidence for this lies in many historical buildings, which have withstood earthquakes throughout the hundreds of years without having been reinforced with special material. The fact is that the master builder or Mimar (traditional architect) of historic buildings was simultaneously designing the architecture as well as choosing the suitable form, proportion, and material for the best structural performance.

Abstract

  The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning. The case study area is Paveh stream in the City of Paveh. The data from the case study area were gathered from questionnaire, existing scientific and library studies and by conducting interviews with residents and authorities. Once the importance of the biodiversity of the stream had been studied based on the existing ecological data, the social importance of the stream and the linkages between human health, social well-being and the biodiversity of the stream ecosystem were addressed.

  Based on the results of the survey and other sources of information, it was discussed that urban stream ecosystems can be rich in biodiversity and function as ecological movement corridors for species .Urban stream corridors can thus be an important part of the urban green infrastructure .Also we can make the weather fine, extend green space, prepare peaceful environment for residents and bring the countryside effects of nature into cities through improvement of stream landscape.

Finally, regarding the finding of this study some suggestions and implications are mentioned to improve the quality of the stream.

Abstract

Cracks emerge due to various forces or stresses. After discerning the cracks preferably by non-destructive techniques, there is a need to find the reason for their appearance. With very exact analysis of the shape, form and dimension of the cracks and their location on the structural elements, we can deduce the reason for their formation. This makes, proposing a suitable solution for preventing the expansion of cracks possible.

Abstract

This paper will promote many questions about the design validity of these exciting blocks. The physical design of these blocks is prone to have social and economical problems, and it is part of the visual pollution and disturbance created on the sky line of Scottish cities special Glasgow. This paper focuses on the necessity to establish a source of initial design for high rise housing design problem classes theory. A thorough research of all the estates in Glasgow area was launched. Thus, a high amount of information was classified, in an attempt to establish a theoretical approach to support the evaluation and appraisal of current blocks problems. The new class's theory in high rise housing design problems is used as a vehicle for conducting this paper analysis. Classification includes physical and social design problems domains. The physical problems domain variables of the numbers of stories, dwellings, entrances, type of corridor, access from the streets and sharing of the site. Furthermore, to the social problems domain variables of graffiti, damage, litter, crime, drugs, child density and health have been examined. Moreover, their interdependent relationships were explored throughout the new classes' theory. The study of the new classes, theory may prove to be extremely vital for future direction in adapting some from of urban design problem solving techniques. It also serves as an evaluation tool for housing design appraisal in the city from Glasgow and similar cities worldwide.

Abstract

Mosque architecture is considered as a potent visual symbol of the Islamic architects’ design ability. Prayer-hall as the manifestation of equality between the believers and the unity of architectural space has challenged such an ability throughout the history. This study, considering the characteristics of light-openings in the domes of Iranian mosques’ Prayer-hall, aims to investigate these domes’ possible relationship with the climatic features of each mosque. To this end, eighteen case-studies according to the research analytic approach are studied to determine: 1. the relationship between the mosques construction period (Iranian architecture styles) and its light-openings number on the one hand and its climatic features on the other hand, 2. The relationship between the light-openings’ location and the climatic features of each mosque, 3. The relationship between the lightopenings’ number and the climatic feature of each mosque and finally, 4. The relationship between the prayer-hall’s height and the number of light openings of each mosque on the one hand and its climatic feature on the other hand. The study shows that Iranian architects have given considerable priority to the natural ventilation function of the light-openings, So, what used to be considered as the domes' main function, allowing the light to the interior space, is considered as their secondary function.

Abstract

According to Islamic teachings, human being moves towards perfection if conditions conducive to His/her calmness are realized at home. According to this view, 'house' represents 'family' and a Muslim's home is regarded as Sacred and private. There is an inherent tendency in human being towards privacy, the most important of which is realized at home. Therefore, if privacy is trespassed at home, it may no longer serve as a home. As traditional houses have assumed a more architectural manifestation due to religious principles (Shariah), identifying these principles and converting them into housing rules and regulations are among the major concerns of urban planners. This study introduces, analyzes, and compares privacy and hospitality pattern in the nomads' tents and permanent dwellings through a combined method. In this paper, some of the behavioral patterns related to the privacy, as mentioned in Holy Quran’s verses, are introduced. The evidence also comes from religious texts showing that nomads’, Muslims’ and Zoroastrians’ tents in Kerman have been influenced by religious beliefs. The findings of this study stress the need for privacy and shows that there is a direct relationship between the concept of family in a culture and the scale of privacy and territory .

Abstract

After disasters, one of the main challenges confronting authorities is site selection for reconstructing damaged structures. Experiences indicate that appropriate policies in site-selection could greatly influence on reconstruction success and residents' satisfaction. Meanwhile, in literature related to post disaster reconstruction, avoiding from relocating settlements is generally emphasized. However, when relocation is inevitable, adopting proper procedures is necessary to gain success. This article is about reconstruction of Rofayye' -a town in Khuzestan Province of Iran- after the Iran-Iraq war, which is a distinguished experiment from different aspects. Then all the town's components relocated from their situation, but in newly built city, still every part has an identifiable vestige of the former Rofayye', that’s why some researchers considered it as "in-placement" by mistake. In this article, the narrative of annihilation and recreation of Rofayye' is described and important specifications which are considered when dealing with urban planning and design are explained. The main issues include preservation of formal fabric structure, neighboring pattern, tribal territories, former plot areas, and situation of distinguished urban elements. Moreover, providing urban standards and properly allocating responsibilities between authorities and residents were considerable. The article is based on an intensive research and practice done during Rofayye' reconstruction in 1980's. The research performed by qualitative method through extensive field study and analysis of maps, documents, and pictures. It is hoped that study of the instructive points of this experiment lead to improved future reconstruction programs.

Abstract

Shohada (Sepah) avenue in Qazvin, a historic city, is a part of Safavid era infrastructure of the city. It connects various important cites and poles like Jame' mosque, Imamzadeh Hosein, Dowlat-Khaneh and the Traditional Bazaar complex to one another. This axis in KhomarTashi, in Kabir Jame' mosque - preservation and restoration of Jame' mosque complex as principle core of the city which is engraved in Kufi epigraph under the mosque's dome, is located on the western side of this avenue. This is a valid document that shows neighborhood organization of a Saljuqi city. This epigraph describes management terms of the city, income resource and has references on civil society with shared responsibilities like a covenant. Sepah Avenue has a pivotal role in this historic context and is remnant of pre-Safavid era. Therefore, studying its historical evolution is necessary to define its position in contemporary historic city. This article contains direct findings of a research accomplished by the authors in a field study in Sepah Avenue and evaluates restoration and revitalization goals of Sepah Avenue.

Abstract

Preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. If the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. Regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have been produced for outdoor thermal analysis during recent decades. The different methodology and approach to these indices have provided a diverse set of responses to thermal prediction of outdoor spaces. This diversity has made it difficult for architects to decide how to use these indices in outdoor design strategies. To provide a same basis to compare these results, this article will introduce each index with its definition, its basic calculation method, and its thermal condition categories. Following these information a psychometric chart that is provided by the author, shows its thermal categories as a graphic method. Using this psychometrics for thermal analysis will make it easy to compare different indices and their outdoor thermal predictions. Those architects, who are familiar with Building Bioclimatic Chart of Givoni for analyzing indoor thermal conditions, will find this method easy and practical for analyzing outdoor thermal condition by choosing an appropriate index.

Abstract

Throughout the early and mid 1990s, there was widespread faith in the compact city model's ability to provide urban sustainability. However, where compact city policies had been implemented, follow-up studies began to show the predicted benefits did not happen as they should be. The article tries to peruse two opposite approaches of "Urban Sprawl" and "Compact City", with an analytical - critical procedure and their consistency with sustainability. It also compares sustainability strategies of the new urban design paradigms (such as New Urbanism, Transit Oriented Development (TOD) and Smart Growth) with compact city considerations. At the end, the article discusses about the question that does the compact city paradigm creates an obligatory context for sustainability? In fact, This article supports the belief that instead of concentrating on one particular solution, there is a need to recognize and accept the fact that a divers urban futures are likely to exist within a city and that urban compaction should only be seen as one way of achieving sustainable urban form. As indicated in the article ,each country should adapted the compact city considerations that best suits the local conditions and makes the best contribution to urban sustainability in a way that is both acceptable and feasible in their local environments. Because of the many challenges that the compact city concept faces, the focus should be on creating a diverse urban forms and sustainabilities that are most likely to 'fit' the area they are to be implemented in. Indeed, there should be a greater focus upon the processes, functions and design of the city and how they contribute to sustainability, rather than just the density dimension of compact city which occupied most of the literature throughout the 1990s. By concentrating on a more micro level scale, urban design can help overcome acceptability and feasibility critiques of the compact city that correctly highlight the radical cultural, political, social and institutional changes that will be required to move away from the sprawl.

Abstract

Living in satisfying urban environments is important for an individual’s well-being. In order to create such environments, planners, designers, and policy makers need to understand the structures that cause residents to feel satisfied with their environments. This paper focuses on the perceived quality of urban residential environments: dwellings and neighborhoods. First, literature review was conducted to extract a list of relevant attributes of environmental quality (EQ), which in turn became the theoretical basis for the rest of this work. Next, the general research methodology, the multi-attribute evaluation of perceived quality of urban residential environments, was presented. Hierarchical multiple regression was used for data analysis. Using written questionnaire, residents in two neighborhoods of Tehran, Zafaranieh and Khaniabad were asked to evaluate their present residential situation on the various residential attributes. Due to the presence of north-south dichotomy in Tehran, researcher tried to compare perceptions of the residents of these two neighborhoods. Regressing the general satisfaction evaluations on the specific evaluations revealed a model fit which appeared to be relatively high (49%). It was concluded that next to physical attributes, psycho-social attributes and attributes of built environments are relevant attributes, and EQ may best be seen as a hierarchical multi-attribute concept. Subjective evaluations varied across two neighborhoods and results showed that older people were somewhat more satisfied with their residential environments than younger people.
