Creation of urban identity is the important subject in architecture and urban design. So, this article foci’s on the Creation of Identity in Urban context with Participation approach in Architecture and Urban Design. Corporate architecture is an architectonic discipline which focuses on designing and constructing buildings, spaces or environments with the aim of meeting the needs of a business community. Its objective is spatial perception of corporate values by the company’s employees and customers because for motivation and communication, conveying the corporate values and philosophy clearly is of essential significance for success. Place identity could best be understood as that which makes a place unique. The identity concept from the point of cities and architectural products includes a wide definition covering natural, geographical and cultural products and social life norms. Urban identity, architectural identity and the urban images about them are sometimes formed by very different components in a long period in urban space. In recent days, we often come across with the problem of cities to enter a new architectural and urban formation process in a dimension of losing their original identities. In this context; the city identity is formed in the togetherness of urban participation and natural and cultural values which are required to preserve, unique architectural and spatial characteristics, social accumulation and life style. City identity concept having spatial, social, cultural and economical dimensions should be handled with a totalitarian approach, it must be qualified as a collective result including the urban participation and every interaction which provided the city to reach social participates.

Sustainability creates solutions that solve the economic, social and environmental challenges. It has been studied and managed over many scales of time and space and in many contexts. The paper reviews the definitions of sustainability respecting the ecologic concept as well the need for balanced sustainability within its three pillars on equal way, then it goes throw Ecologic Architecture with its core requirements and how it’s important to work within the framework of Ecologic Architecture. In the aftermath of climate changes there has been an increase of overall interest in sustainability of Environment material. Sustainable development in living environment is not only a trend. Similarly sustainable development in modern bathroom is not a fad. Contemporary societies are not able to function without water, energy, heat, electricity and fuel. It is obvious that the precious natural resources are not available in unlimited quantities. Therefore is absolutely no alternative to necessity of sustainable development. Man must learn to be more careful with using of natural resources; in this paper describe the Livable eco- architecture that have been explained the interaction between sustainable house and urban conditions in analytical approach.

The political and social system involved in the limbo between tradition and modernity of the Qajar Era caused widespread and quick developments in Iranian culture, art, and architecture as well as a challenge between tradition and modernity. Relatively numerous palaces built in this era were signs of greatness and distinction-seeking of the Qajar kings and aristocrats, who embraced all transformations of architecture in their era and played a significant role in changing Iranian architectural values. Therefore the purpose of the present study is to investigate developments in architecture of the Qajar Era and their effects on the evolution of palaces in this era. Using case studies methodology and referring to historical sources, contemporary studies on Qajar architecture and field studies conducted on outstanding palaces of this era, it can be concluded that the continuation of Safavid architecture early in this period, Qajar kings' tendency to Iranian ancient architecture, and the culmination of the architectural influence of the West in the Nasserid Era were the main factors effective on the formation of Qajar palaces. Moreover, the evolution of these buildings has occurred in three pre, early and late Nasserid Eras with various traditional, eclectic and European characteristics regarding the construction period and the effects of the above factors on the evolution of plans and circulation systems, facades and sections, materials, decorations, and architectural elements. In addition to shedding more light on common features of architecture and decoration of Qajar palaces, the study tried to determine their general and specific differences.

One of the most traditional architecture and urban planning patterns is bazaar. The aim of this paper is studying social, economical and architectural features of traditional bazaars. The claim of this study is that they are significant relationship between social and economical values of bazaars with their architectural values. Bazaar usually is located along the main routes of the city and extended to the city center. Most activities and exchanges of city happen in the bazaar. In the past, the bazaar was a place for the transfer of customs, traditions, ideas and practices of social behavior and social life. Bazaar as a social media and social network, bazaar a source of social capital, forming micro funds are the greatest economically and socially achievements in the traditional bazaar. Wakf in addition has socially and economically important functions in day-life and urban activities, also has in physical aspects vital roles in shaping Islamic cities especially Iranian cites and bazaars. One of the most important features of bazaar’s set is formation guild organizations, socio-political, and the founder of this organization, which may be composed of civil society. Most of these activities and values are related to architectural and physical features of bazaar.

Investigation on modern history of urban planning in Iran shows that there are three approaches in the subject under discussion: “Modernism and Westernism”, “Traditionalism and anti-Westernism”, and “Adopt and Adapt”. Proponents of the first approach believe in encouraging methods to use the external concepts. The second, is the idea about ​​cultural and religious values, ​​thereby everything with nontraditional orientation is rejected. In the third approach the thinkers believe that if the parts of tradition are synthesized by modernity, culture and religion can adapt themselves with the development. The purpose of this study is to evaluate the adaptation of traditional urban design patterns of Islamic-Iranian cities in incompatible district of new Iranian cities (spontaneous settlements) and to focus on the application of the third approach in the current situation of Iranian cities. On this basis, the method of comparative analysis has been applied to survey the differences and similarities between historical districts and spontaneous settlements. Studies show that there are rather similarities among physical - spatial parameters (such as structural and environmental criteria) between the two types of districts; because both of these residential districts formed as organic structures that are unstable against unexpected risks and earthquake. However, there are the differences between these two types of districts in organized and formed periods. Despite historical districts that have been consolidated and organized during hundreds of years, spontaneous urban textures formed quickly and without any plan and planning. Meanwhile, the historical districts have usually integrated townscapes and unique materials such as clay, bricks or stone, while this character (integrated townscape and unique materials) never have been seen in the spontaneous settlements. There are similarities in economic and socio- cultural characteristics between residents in the two the types of districts. The residents living in poor economic condition, but under a very strong socio-capital and traditional beliefs; There can be seen several socio-cultural and particularly religious characteristics in people of historical residential districts that are similar with the spontaneous residential places, such as “strong relationship among families, friends”, “hospitality”, “mutual relationship among family members”, strong religious beliefs and the needs for privacy and security. However, these communities are different in some principles such as quality of life and spatial and physical qualities especially in favorable and beautiful urban landscapes. So it can be extracted and adopted excellent principles from traditional and historical districts and adapt them to the inappropriate modern urban districts. With regard to the existence of these similarities, we explain applicable principles of the spatial characteristics and designing quality in the historical district of Yazd to apply in Baghshater District in Tehran as a spontaneous settlement. Findings show that we can use several solutions to reconstruct this zone included: 1) land readjustment as the suitable solution in Baghshater District with regard to the familial residential pattern in historical zone of Yazd such as Fahadan District. 2) Focusing on the traditional concept of mutual relationship in residential houses. 3) Emphasizing on the hierarchy of The entrances and exits of the residential units.

Hail phenomenon is one of the hazardous weather phenomena that can make the highest amount of damage to farms, gardens, cars, rooftops, etc. in a very short time (a few minutes), depending on the diameter of the particles. One of the best ways to study this devastating climatic phenomenon is the use of atmospheric instability indices. The indices which are calculated with the help of radiosonde data give a fairly comprehensive vision regarding the occurrence of such phenomenon. In this study, the incidence of moderate to severe hail is investigated in the period of 1990-2010. First, the atmospheric codes related to hail phenomena were applied to extract the data, then radiosonde data in intended time were received and applying the RAOB software, the physical status of atmosphere was studied. In the studied period, two hail examples were reported on November 27, 2008 and December 5, 2008. In the first instance of hail that occurred on November 27, 2008, the status of some indicators was calculated and it was found that LCL was at an altitude of 284 meters, CCL at an altitude of 1582 meters, LFC at an altitude of 6230 meters, the ice surface at an altitude of 3278 meters, the LI index was -0.2, the K index was 25.7 ° C, and PWC was 28 mm. In the above mentioned conditions, there was a hail with a diameter of 25.4 mm. In the second instance of hail that occurred on December 5, 2008, the status of some indicators was calculated and the results showed that LCL was at an altitude of 280 meters, CCL at an altitude of 1762 meters, LFC at an altitude of 2271 meters, the ice surface at an altitude of 2771 meters, the LI index was -1.4, the K index was 27.1 ° C, and PWC was 23.6 mm. In the above mentioned conditions, there was a hail with a diameter of 3.6 mm. Given that in many ways, the status of most atmospheric indicators in the two above examples of hail were close to each other, it turns out that in similar circumstances, the greater the distance the ice level gets to the summit of cloud, the greater is the probability of hails larger in diameter. The value of this distance for November 27, 2008 was at approximately 6384 meters and for December 5, 2008, it was at about 5012 meters.
