    Courtyard geometry plays an important role in the amount of received solar radiation, also heating and cooling energy consumption of buildings. Considering this geometry for finding its proper proportion and orientation is significant to increase indoor thermal comfort, and as a result reduce the amount of energy consumption. This paper mainly focuses on a dormitory courtyard in Yazd and investigate the effects of it’s different proportions and orientations on the dormitory energy demand to reduce energy consumption. A computer software (EnergyPlus) was utilized to conduct the survey on base model which was obtained from existing university student dormitories in Yazd in a hot-dry climate of Iran. The findings indicated that the proportions and orientations of the courtyard dormitories affect the cooling and heating loads. Also, the outcomes indicated that the use of university student’s courtyard dormitory with the proportion of 3/7 (width to length) and the orientation along east-west axis has the lowest required cooling and heating loads and could reduce the total energy consumption by 3.4 % compared with the most inappropriate courtyards based on their proportion and orientation.

    The external walls are regarded as an important source for the thermal exchange between the outside and inside of a building. Despite the significance of building walls for energy savings, a large body of research has focused mainly on thermal comfort, environmental impacts, and economic costs of residential buildings. However, few researchers have addressed the thermal performance of common building materials. The clay block has attracted a lot of attention as the important building material in temperate and humid climate. The present study aimed to study the thermal performance of three clay block external walls systems in temperate and humid climate by increasing trapped air thickness between internal and external walls of buildings. FLUENT software was employed to simulate and calculate the thermal characteristics, which were extracted and compared to the calculated data according to chapter 19 of "Iranian National Building Regulations". The results indicated that the air trapped between the internal and external the leaves of cavity walls considerably influenced thermal resistance. In addition, the new combined wall system could considerably save the energy, compared to the existing wall systems. In conclusion, the energy goals can be fulfilled by improving the layout of the walls.

    To date, researchers from various disciplines have studies leisure time; most have focused on quality of leisure activity, psychological benefits of leisure, spiritual effect, thereby neglecting the effect of social classes on features and quality of the selected place. Third place is defined as a location outside of home or work that allows for social interaction and emotional support, regardless of levels and social classes, ethnic and racial differences. While it seems that the presence of such places in our society has a significant relationship with social classes; in the sense that different levels of social classes are more apt to form distinct number and types of third places. The current research tries to investigate the relationship between different social setting and people identification of third place, for spending leisure time. People attach identifications or meanings to these third places based on the type of needs met for the individual by these places.

    According to several types of research, one of the most important issues and principles of sustainable development that urban professionals pay attention to it recently is Just City. One aspect of Justice in cities, spatial justice, has particular significance by Unequal and discordant Expanding in cities regarding creating unequal areas. On the other hand, the urban spatial structure affects the equal distribution of elements and services. If this structure is devoid of justice ideology will lead to a complex social crisis and spatial issues as spatial conflict. Accordingly, this study aims to analyse the spatial justice and structure in the case of Yazd city to know how they influence each other. Spatial justice is examined from the view of "Equality of opportunity". Involved criteria are "equality", "Physical diversity", "human diversity" and "urban spaces", and spatial structure based on “Space Syntax” technique with "integration", "control", "connect" and " intelligibility " parameters. These criteria are Scored and analysed by FDAHP techniques and GIS. The result shows favourable status in the Central District, and as getting away from the disadvantaged downtown District increased. On the other hand, the spatial structure analysis reveals the most spatial coherent analogue the north-south axis with a little depth and isolated District (Spatial segregations) have located in the corners and edges of the city. Results from the superposition of these two analysis layers show a compatibility relation between the spatial structure of Yazd and the pattern of justice distribution except in the central and historical centre.

    The key issue in the design of today’s living spaces is the cognitive and socio psychological gap towards individual and social needs of today's human. Place attachment as a quality of urban space has a kind of product-oriented output and requires careful attention to the stages and process of attachment. In the analysis of this process, familiarity with cognitive structures and novel research methods in the field of cognitive psychology, provide designers with valuable information. The main aim of this study is to investigate the role of cognitive psychology approach in the process-oriented study of place attachment. The research tries to address the issue that "how does the process-oriented model is realized in place attachment with an approach of cognitive psychology?". Research is a combination of qualitative (interview) and quantitative (questionnaire) methods. In order to determine the appropriate number of participants, first a pretest was performed as a pilot study on 40 residents of the neighborhood and after the estimation of variance for the initial sample (S2) at the confidence level of 95%, the number of the sample was increased to 297. The findings of this study suggest that the most influential criterion on the attachment of residents, is the affect (0.97) dimension; Behavior (0.86) is the second and cognition (0.74) is the third one identified in terms of process dimensions. This research introduces influential criteria in the promotion of affective, cognitive, and behavioral dimensions of the place attachment process and also investigates the effectiveness degree of each dimension.

    Undoubtedly, public spaces can be considered as an essential factor, which could contribute to urban arrangement, create and maintain a strong local center and enhance the quality of superior environment and the sense of citizenship. Moreover, integrity has always been the most basic structural qualities and one of the key principles of cities. Integrated urban spaces exhibit the integrated structure of spatial organization in a city where, not only conjunction and space functions are considered, but also identity finds its place in the complex urban system. Therefore, the processes of planning, designing and construction of urban spaces could be helpful for solving structural problems in urban models such as lack of integrity in cities and their spatial analysis. The main purpose of this study is to present a conceptual model of an integrated network for urban spaces in the process of decision-making. Undoubtedly, such networks that strengthen the structure and integrity of a city bring about socio-economic growth and prosperity for inhabitants. Therefore, this study seeks to propose a conceptual model for developing integrated urban spaces network. The main research methods are content analysis and inductive reasoning. The main approach adopted in the analysis and design is that of "living community" in New Urbanism movement. The results reveal that urban spaces are located in a logic network as transects, and to achieve spatial integrity, the continuity of transverse parts of the city must be maintained, as provided in the form of a continuity matrix.

    Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, and correlation of these variables with spatial structure of the province during the years from 1996 to 2011. Quantitative method was employed for this aim and urban rank-size index was used to analyze settlement pattern of West Azerbaijan province; Kernel density and Moran method was used to analyze population data; general and local Moran data were used to analyze activity data; and regression method was used to see the degree of correlation between these variables. The results showed that spatial structure of west Azerbaijan was monocentric in 1996 while the of spatial distribution trend of the population and activity indicated decentralization tending toward clustered spatial pattern during 15-year period of time, due to high correlation between the given variables. In other words, some kinds of decentralized convergence took place. Such trend would change the spatial structure in West Azerbaijan province and needs to be properly oriented in the future planning of urban and regional development.

    Urban planning rules and considering land use regarding faults can change the consequences of natural hazard such as earthquake. Vulnerability risk is increasing in Region 1 because of existence of the north fault, steep slopes and continuous construction of high-rise buildings. It is clear that Region 1’s Master Plan shouldn’t be prepared without considering natural hazard such as earthquake. This study targets two main goals, first, to assess the degree of land use vulnerability to seismic risk and second, to classify areas based on their vulnerability degree. Nine indicators were extracted from previous studies to analyze the vulnerability of land use in Master Plan of Region 1, Tehran. According to different features of each indicator a score from 1 to 4 was allocated for each feature. The vulnerability degree of 181 areas were shown using Categorical Principle Component Analysis (CATPCA) in which areas were divided into four categories and the final result was visualized. The main results of this study showed that more about 50% of the areas were located in the highly-at-risk region. It was concluded that increase in the building density, number of floors, and distance from open spaces would be resulted in higher risk of earthquake damage. The major practical contribution of the present research was that it provided evidence to show that much focus required on reconsidering seismic risk in the future plans.

    Informal settlement as a global urban phenomenon encounters different social, physical and economic shortcomings. These fabrics especially in cities of the global south experience an escalating gap with developed urban areas. In this regard, faltering economy plays a major contribution in continuity of poverty and exclusion. In Iran, Empowerment plan could not lead to favorable and stable results which has mainly been related to stereotypic, homogenizing and dehumanizing viewpoints to current empowerment plans. As regards the ultimate effectiveness of place branding becomes true in economic context and these settlements are one of suitable candidates for branding, the main aim of this study is improving economic empowerment plans realization for informal settlements through integration urban planning with place branding process to determine more efficient strategies for falak-e-din informal neighborhood by its identity and discovering how place branding, economic empowerment and place identity have conceptual, practical relations with each other to signify this integration. The method of present study is mainly qualitative which is best to cognition of place complexities. Falak-E-Din settlement, has been selected as the case study because it benefits from place market maker advantages and yet encounters the threat of identity crisis. Surveying practical and theoretical facets of Results show place branding with a focus on marketing view is trying to use all aspects of the place(as a complete identity) to draw the image of economic prosperity through comprehensive branding strategy. The findings from analysis of gathered data from inhabitants(observation, interview and archival data) by SWOT and evaluation through brand creation process in Falak-E-Din quarter by ANP ( Analytic Network Process) based on evaluation criteria- reveal the best alternative for creating Falak-E-Din quarter brand is to provide brand strategies based on the brand identity which is built with an emphasis on quarter human factors. Accordingly brand strategies are codified at four main steps to create chosen brand identity: create direct and indirect job opportunities, physical elicitation of place personality with execution of physical components of the brand identity, physical complementary proceedings, and eventually marketing proceedings which include final actions that lead the place to its economic purposes.
