    Given that Peighambarieh street in the historical context And valuable Qazvin, Which has historical and cultural, But it seems This street appeared during the time period until today, There were many inconsistencies, Therefore, it is necessary that this study, considering all the physical and non-cellular factors affecting the range, Provide solutions for it. Research Objectives include: 1- Recognizing elemental identity elements and providing strategies for strengthening the desired elements and undermining undesirable elements, redefined identity; 2. developing solutions for the physical and cultural reconstruction of the historical-cultural center of Qazvin Emphasizing the context-oriented approach. Descriptive - analytic research method by relying on the background of the research and review documents related to the historical context of Qazvin and field studies, on the other hand, analyzes the issue. Finally, to answer the main research question (In the organization of the cultural-historical axis How to use the principles of the context-oriented approach is the space useful for users?). The findings show that by organizing the sector-based identity elements Contains: Chharanbya, Grand Hotel, Shahrbani, mosque panje-Ali and Alighapou building you can revive the historical context on this street, also adding new roles to historical spaces, to create charm and socialization Thereby attracting people to these spaces and also helped promote cultural background. On the other hand to improve the pavement path of this street from the footage combining GoleBoteh designs and to organize the walls Use wall paintings it has been suggested to combine GoleBoteh & GoleMorgh.

    Deciding the roof type with a large ventilation spans for uses in the flower and plant exhibitions that can operate beyond the exhibition space functions as it can provide a desirable climate for the growth of its plants, it can be designed and enhanced according to the geographical site of it. Deciding and designing the roof form can prevent dissipations in energy and assets and develops a construction with high efficiency together with low costs of maintenance, only if it is done in an intelligent way. The independent variables in this research are the climate conditions, and form of the structure is considered as the intervening variables together with factors like the internal air current and sub climates and the levels of thermal comfort for individual occupants as the dependent variables. The aim of conducting this master thesis which is considered as an interdisciplinary research, is to reach for proper patterns in covering the ventilators in greenhouses with large spans by using the climate information of the north-Iran region. The main question of this research is the most efficient roof form in regard to natural ventilation in mild and humid climate condition? Research method the study is modeling and computer simulation in a way that they are evaluated with the prevalent forms of exhibitions and greenhouses with large vents in the terms of the external wind flow impacts and natural ventilation in their interior and analyzed by employing Computational Fluid Dynamics (CFD) and moving particle semi-implicit (MPS) simulation. Results indicate that form of a building has an obvious impact on the internal airflow and the curved forms have a better impact on the internal circulation of air. As an instance, in the convex geometries, the airflow speed rate drops in the center of the construction while in the concave geometries it is quite the opposite as the speed is reduced around the sidewalls of the construction and the thermal comfort becomes a different point along with natural ventilation.

    Traffic problems are the most prominent urban dilemmas, especially during recent years, since the capacity of old traffic arteries don’t meet the increasing volume of population and vehicles, therefore, adopting some measures in order to enhance the capacity of existing roads has been placed on the agenda of urban managers. Changing the existing intersections to over changes is one of these methods. It seems that these structures which facilitate traffic dimension in some cases and after a period of time since exploitation make considerable impacts on other dimensions especially in terms of economic and social perspectives on neighborhoods. This research is the result of investigating the impacts caused by construction of four unleveled crosses of Shahid Motahari, Kowsar (Shahid Rajaei), Sardaran, and Seyed Hasan Nasrallah (Nasr) on their surrounding neighborhoods in Qazvin city and during a 6-year period since 2011 to 2016. Extracting and investigating the existing documentary data from prior-to-construction to the end of research period besides obtaining the comments of citizens and managers and then, statistically analyzing the results of SPSS and how the impacts affect neighborhoods and desirability rate of crossroads in terms of being overpass or underpass were of the main goals of this research. Also, developing the SWOT charts and applying the AHP method and recommending the practical solutions on the basis of extracted results in order to enhance desirability and to reduce negative effects of these crosses were of other measures performed in this study.

    This study aims to use vernacular climatic solutions (VCS) of traditional dwellings of Bushehr in common residential buildings of this city in southern Iran and answer to the question that “What is the effect of VCS in terms of energy consumption in these buildings?”. This research was conducted on two levels. At the first level, after selecting an existing model of common residential buildings and short-time field measurements from local climate throughout the year, the collected data was used in simulation and some changes in terms of improvement in shading, natural ventilation and insulation of external walls and roof as vernacular climatic strategies were made in this building. At second level, the proposed models of common residential buildings were offered and the data collected at the first level was used in their simulation in two states of with and without using VCS. All models were simulated with the Design Builder software under natural ventilation conditions in moderate periods of the year while split air-conditioning systems were used during hot and humid periods. The findings showed that in the existing model, discomfort hours, cooling energy consumption and CO2 production reduced by 54 percent, 44 percent and 22 percent, respectively. In the proposed models, these values showed a decrease by 10 to 20 percent, 42 percent and 32 to 34 percent, respectively. It is also predicted that using the VCS in common residential buildings of Bushehr, could reduce the energy consumption of each household by 3500 kWh per year.

    In this study, by recognizing geographical location changes of the sun-path diagram, we present a selection of sustainable architectural guidelines that influence the climatic element of sunshine. For this purpose, after the introduction of triple zones of the earth in terms of how the sun is exposed(include:Tropical, temperate and polar), the function of the earth's curvature to create geographical location differences in the angles of sunshine in both its altitude and azimuth, is explained. In the following, using the "Rayman" software, the sun-path diagram on the days of the summer and winter solstice (revolutionary) is drawn up for cities selected in the triple zones, and the geographical location differences of these diagrams are described. Also, due to the climaticrequirement in some of the studied cities, the "PET" index has been calculated, and in the other cities, the "Analemma" graph has been used to determine the frontiers of the sunshine and the number of days per each front. The research findings, suggest a deep geographical location difference in the patterns of the sun-path diagram for the Earth's sunshine zones. At the end, a selection of architectural guidelines for the use of passive solar energy is proposed for residential buildings in the above cities. These guidelines are presented in the following topics: Optimal orientation and determine of an appropriate front for lighting the building and estimating the size of the horizontal overhangs for the sun-facing windows.

    In the wake of Jacobs’s criticisms of planning, planners increasingly felt a level of angst over, or even responsibility for, the condition of the city. Schooled in preparing and implementing plans and land use regulations, they appreciated the appeal of a new movement that offered a simple, tangible, and marketable recipe for practice. New urbanism theory is one of the contemporary urban theories that developed as a movement within practice as a response to the failure of cities and suburbs in the mid-twentieth century. Now these questions take shape in a mind: May New Urbanism lead to Planning good community? How is new urbanism developing theory, and how does it contribute to our understanding of theory? How is planning theory responding to new urbanism and the insights its practice generates? These are questions that the paper tried to answer them. Using content analysis, various ideas and views about New Urbanism and its formation from theory to practice have been reviewed and criticized. We concluded that although the new urbanists want to turn the situation around and they envision cities without suburbs, but in practice, they could not make good community According to the principles that this normative theory committed. In present day most new urbanist projects have proven relatively homogeneous in composition. Rather than minimizing difference, new urbanist projects have sometimes exacerbated societal differences by creating enclaves of affluence in the urban environment.
