This paper seeks to investigate a new definition for architecture by unifying the three Vitruvian principles of firmitas, utilities, and venustas via a phenomenological approach in the interpretation and analysis of their role in defining architecture. The paper is composed in two main sections. The first section investigates the nature of architecture based on the mentioned principles, where architecture is interpreted and analyzed in terms of its “thingly,” “equipmental,” and “artistic” characters. While it seems that architecture could be in view of its “thingness” alone, or “equip mentality”, or “artless”, but each perspective reveals only a dimension of the nature of architecture. Therefore, the second section of this paper focuses on unifying the Vitruvian Triad, attempting to define architecture from the single stance of “architecturality” the sphere from which architecture is seen as a way of disclosing the truth in the desired life of humans in an architectural work. In this definition, there is the simultaneous presence of thingness, equip mentality, and artless of architecture, thus establishing an integral unity between the principles of the Vitruvian Triad. Thus, the three Vitruvian principles come to unify in architecture which is defined as “the manifestation of truth of human desired life in the work of architecture.” This definition also allows us to assume three fundamental principles for architecture, “truth of human desired life”, “work of architecture” and “manifestation of truth”. These three principles are themselves, in fact, reflections of the three Vitruvian principles.

 This article addresses the analysis of the mechanism of natural air flow around the residential buildings  and the effect of the form of residential buildings on air flow among four building forms in Tehran. The aim of this research is to study the effect of the form of residential buildings on the mechanism of natural air flow with the purpose of optimally utilizing clean air. The research method is to use computer modeling and model analysis in the related software and conclusions have been achieved using comparison of outputs of the models produced. Accordingly, four samples were first selected from software forms and modeled in one commercial micro-climate simulator software. They were tested by entering Tehran climatic data and results were extracted as simulation images. Since the analysis was conducted in one hour interval in the morning of the 23rd of December 2013 among four selected forms. The results helped us to choose the optimal form among these cases. Thus, a general rule was not given regarding the case that the selected form is the best in all aspects. Research achievements indicate that building forms have a significant effect on local winds and air pollution reduction. Therefore, the general form of buildings affects the degree and type of pollution dispersion due to carbon dioxide and the retention effect of suspended particles.

Looking from an historical perspective, it can be seen that many civilizations have lived in the country and consequently produced many different cultures and architectural products. One of the oldest cities which contain such historical examples which have lived until present is Tabriz. Its traditional houses are the most important places to represent the life style of the past. Lack of recognition and appreciation of these buildings by authorities and the public will gradually lead to their destruction and replacement by contemporary buildings. The present study seeks to introduce specific architectural features of traditional houses in Tabriz. Preservation of the features of these houses helps maintain the architectural heritage and culture of the region. Most old houses in Tabriz were reconstructed at the beginning of the Qajar era after a devastating earthquake in 1780. The destruction caused by contemporary constructions, in the chaos of modern period, makes it difficult for researchers to gather information about the principles of traditional buildings and to identify their typology. The survey is a compilation of a process in the typology of 52 traditional houses of Qajar and Pahlavi periods in Tabriz. The study revealed that it is possible to accomplish the classification of the monuments with the application of a quantification process in which the qualitative data related to architectural elements was successfully converted into quantitative data by assigning numerical values and using coefficients.

Today city residents are experiencing a new way of life which is unprecedented ever since the urbanization concept appearance. The continuous demand to build and maintain the real city space with all the well-known problems, alongside the simultaneous management of urgency and the presence of a developing virtual parallel world, has baffled the city's management sys tems and city's residents. One of the proposed solutions is employing a machine approach to solve these related issues. The general purpose of this research is to provide a comprehensive definition of the concept of urban technology synthesis in the area of physical space as an urbanism machine. This inves tigation is a comparative s tudy to allocate and provide a particular paradigm for the introduction of augmented reality ins tances utilizing matter and information combination via technology in urban spaces. After the semantic framework formulation of the mentioned concept, recognition of tools ins tances in the context of nowadays cities have been considered. In the process of this research, the phenomenon of augmented reality has been retrieved, with its definitions and capabilities as tools for the realization of technological synthesis in the context of current cities. Another result of this research is the introduction of some advantages in applying augmented reality in cities.

Iran has an arid climate which characterized by long, hot, dry summers and short, cool winters. Therefore, sunlight and its heating effects were important factors of Iranian architecture and gardens structural design. Textures and shapes were selected by architects to harness the light and supply a shadow in the summer. Water is very important in this climate, both in the architectural design and longevity of gardens. In addition to water, the plants in Iran had been particularly significant. In ancient civilization of Iran, plants have had special position. Supernatural powers that had been in trees such as life-giving, young giving, productivity and Immortality made them sacred for Ancient Iranian people. However, attending to supernatural power of plants was the importance reason that people regarded to plants and made some symbols such as “Life Tree” has income. In Zoroastrian religion books, more values have said about Supernatural cost of plants. Plants have a special value in Zoroastrian Fire Temples, religious ceremony and routine life. Therefore, garden and gardening were sacred for Iranian. The term Zoroastrianism is, in general usage, essentially synonymous with Mazdaism, have discovered dependent on Achaemenids Empire (559–330 BC) and there were in Pasargad. In the Islam tradition the garden as Paradise is, perhaps, even stronger, since the Quran (the central religious text of Islam) describes Heaven as a garden. Islam was spread to the Persians, and reciprocally the Muslims adopted the Persian style of garden. Therefore garden has been invaluable to Iranians. Persian Garden includes some types which one them is Garden City. Isfahan as the Capital of Safavid Dynasty has designed as a big garden according garden city model. Therefore, some solutions have used in urban design regarding Isfahan's arid climate. Safavid government followed the realization of cities ideal that rooted in Islamic beliefs and opinions. The investigations in historical perspective of Safavid cities indicates the importance of cities as the place for presence of symbols and signs. The Symbols which has remind as the ideological concepts, power of dominating government and also getting identity to the city. During the history of Safavid urban design, there were some direct and wide streets (Charbagh) which were the main factors of development and improvement of cities among urban functional and symbolic elements. In historical background of Isfahan garden city is pointed to construction of street (Charbagh) which has attracted the European tourists attention and it will investigate in this article. Initial section of this article is allocated to explain about historical background of Isfahan city in Safavid era and also Charbagh Street. Then this paper with emphasis on some historical documents and analytical studies, compares the Isfahan Charbagh Street with its similar sample in France (Champs-Elysées Street). The conclusion of this article indicates the similarity of Isfahan Charbagh Street and Champs-Elysées Street in some skeletal specifications and the way of formation. French Boulevards were constructed after Isfahan Charbagh in terms of time and they were formed after publishing itineraries and pictures of tourists from this place in Europe .
