Empirical s tudies in the field of the design process s tarted in the 60s. Protocol analysis is among the empirical research methods that have been developed simultaneously with the growth of empirical s tudies. Concurrent with the use of protocol analysis for researching in the field of the design process, analysis methods have been presented by some researchers, which can be used with the protocol analysis method in order to analyze the s tructure of the design process. Among these analysis methods, problem behavior graph, decision tree, linkography, and extended linkography could be mentioned. The problem behavior graph is based on problem-solving theories. In the decision tree method, the extracted data from protocol analysis is used for the perception of decision-making processes. Linkography is another method for analyzing the s tructure of the design process. In this method, the design process of a designer is unfolding by drawing a graph, which is called linkograph. This paper considers making a s tudy and comparison of these different analysis methods by the use of sys tematic review. By comparison of diverse analysis methods, two approaches could be recognized, formal and informal ones. In the formal approach, the design is mentioned as a logical research process of solving the design problem. The second approach is informal. In this one, the design process is mentioned as a reflective conversation with the situation. In this approach, which is based on Donald Schon’s theories, the design process is referred as an argumentative process.

One of the fundamental notions of realization of sustainable city within the framework of the theory of sustainable development is what affects the urban green spaces as well as the influence they may have. As the upshot of years’ worth of experiences in the ideology of Iranian urban design, Iranian garden is of magnificently high position which possesses the potentials to act as the green space with a variety of functions to serve the promotion of sustainability in today’s cities. Closely studying Dolat Abad garden as one example of the exquisite Iranian garden architecture in a comparative analysis, this study exامینes the role of gardens in the achievement of today’s cities to sustainability within the frameworks of the theory of sustainable city. It will also attempt to prove the hypothesis regarding that Dolat Abad garden and the Taj Mahal have established themselves as sustainable elements in the two contemporary cities of Yazd and Agra, and will accordingly continue to remain so.

Human presence and accordingly establishing suitable condition for social interactions are important factors in shaping urban spaces. Caring to different aspects of improving environmental qualities especially perception aspect and ease of perception from the environment with legibility improvement is an element that was emphasized from the base of urban design. The role of time, commence of day and night and its effect on perception and legibility of the environment have not been investigated deeply. Although time effects the level and the way of perception and legibility and it should be noted that there is clear difference between human perception and space legibility during day and night.This research is looking for effective major factors on urban spaces qualities in day and night with descriptive and comparison method on the case studies and their images of Zanjan and Abadan cities and tries to approve the differences of these images. Results of performing this research clearly approving that, social, functional and perceptional dimensions are the most important dimensions of improving space quality at night. It should be declared that there are a lot of differences between the images and the perception of the city during day and night. In addition, the mention priority to urban five elements in shaping these maps are differ either.

Network of public spaces composes of a network of interconnected land use and various elements of the city, such as synthetic and natural which shows the city as a whole. Network structure of public spaces is important because understanding this network as a structure presents us the formation of the city. This paper attempts to define the status of the network of public spaces in the city structure and to accomplish goals which leads to integration, interconnectedness and cohesion of public space network. For this purpose, a descriptive-analytic method was used and the standards and design principles were taken from the literature review. For collecting the data, Moalem Boulevard in Mashhad/Iran was investigated and analyzed with respect to the physical, functional, visual, social, and historical dimensions of public spaces. Finally, three conceptual options such as a linear pattern, a centralized pattern and a distribution pattern were presented. The results show the factors, criteria, characteristics, urban design framework, policies and strategies to integrate the structure of public spaces network in the area under investigation.

This research seeks to answer what process should be done for a comprehensive analysis and s tudy of producing urban space. The research method of the present s tudy is influenced by the qualitative nature of the research ques tion and to explain a conceptual framework. It has been prepared based on the analytical-descriptive method and sources. Data collection was done by documentary and library methods, and a three-s tep process was performed. In the firs t s tage, document analysis and direct observation of urban spaces and review of some of the lates t research and global experiences of urban space production have been used, which makes the reliability and validity of the research guaranteed by triangulation of evidence sources. In the second s tage, an analytical framework related to producing and reproducing urban space, which includes four general layers, has been developed by summarizing and analyzing them. Then, in the third s tage, the sub-layers of this framework with emphasis on power relations (influence) of related actors have been refined, and the proposed model of space production has been developed. The production and reproduction of space in the city consis t of 4 layers. These four s tages mus t be examined to s tudy the production or reproduction of a specific area. 1-Geographical context (natural context), 2-Time, 3-Formal urban planning sys tem, 4-Social organization or networks of actors (or s takeholders). In this s tudy, a model for s tudying the production of different urban spaces has been proposed from the collection of findings and analyses.

 Todays, cities have become one of the mos t complicated sys tems, which may become fragile when not managed appropriately. In order to prevent fragility, cities should respond more quickly and effectively to complicated threats, which requires an accurate unders tanding of the concept of fragility. In this regard, a sys tematic review was conducted based on Preferred Reporting Items for Sys tematic Reviews and Meta-Analyses (PRISMA) to unders tand the concept of urban fragility by electronic search using keywords combined with Boolean OR and AND operators in Google Scholar, ISI Web of Science, and Scopus. Based on the reviewed articles, the dimensions of urban fragility, including the economic, social, governmental, environmental, international relations, and economic, social, and political conditions of individuals, were identified for each component and indicator. Given the definition of fragility and its dimensions, the present s tudy can provide an opportunity for identifying the causes of fragility in cities and providing some solutions.

   The histories of architectural design and town planning are replete with references to creating a better quality of human life. One of the approaches to enhancing human existence is Vāstu Vidyā , the knowledge of design and building from the ancient Vedic tradition. More recently, Vāstu Vidyā has been repurposed to include not only architectural practice and construction but also considered in light of the consciousness of the designer and builder and the need for a more ‘enlightened’ approach to design. Such a consideration is called Maharishi Vedic Architecture (MVA). Some of the features of MVA include a concern for orientation of the building to cardinal east, the position and proportion of rooms within the dwelling, and considerations of slope and relation to the early morning sun. Such features are said to enhance the creativity, health, and happiness of occupants.  The purpose of the present study is to explore the experiences of individuals who reside in homes designed according to the principles of MVA. Triangulated quantitative and qualitative results from an international mixed-methods survey of 158 individuals in 14 countries indicate this approach to architectural design contributes to individual and family quality of life, specifically as it has been operationalized to mean changes in well-being, health, personal development, and success. On a quality-of-life scale, the study found a statistically significant difference between those living in MVA for more than three years compared to those living in MVA for less than three years ( F = 1.89, p = .02), however no difference was observed between experiences for people living in different locations.  

Considering the determinant role of energy efficiency opportunities in the building sector, proposing guidelines and technical solutions in order to improve the thermal performance of glazing systems is in priority in Iran and other countries. In glazing systems, a substantial amount of radiative heat transfer results from absorption and emission. Applying low-E (low emissivity) coatings on the glazing system is a solution for reducing the radiative heat transfer by radiation in glazing systems, without a noticeable decrease of visible light transmittance. By selecting the proper glazing type, in a hot climate, the amount of solar heat gain can be reduced significantly. Vice versa, in cold climate, the heat loss by long wave radiation of inner surfaces can be reduced. In this paper, first, the thermal and optical characteristics of local clear and Low-E glasses have been measured in BHRC (Road, Housing & Urban Development (National) Research Center) laboratory, by the spectrophotometer and then the thermal performance of single and double glazing units, with and without low-E coating, in different orientations (North, South, East and West) are computed, compared and analyzed for cold (Ardebil) and hot (Bandar-Abbas) climates in Iran. The selection of these two cities is based on maximum heating and cooling degree day values obtained respectively for Ardebil and Bandar-Abbas. The simulation results indicate that using double clear glazing unit with low-E coating reduces the energy consumption significantly in very hot climates, using mostly electrical energy for cooling. In cold climates like Ardebil, double glazing with low-E coating has a minor impact on annual heating load, because of the great amount of thermal radiation, even in the cold season, the high cost of low-e coating and the considerable payback time, compared to the building life cycle.
