Abstract
From the time of human life until now, disasters have had a negative impact on human life; In response, individuals and communities are trying to mitigate the consequences of these disasters and establish scales to assess the initial effects; Also respond to the post-disaster needs and return to baseline. To address these challenges and, as a result, improve the quality of life in cities and metropolises, the need for long-term planning and decision-making in solving these problems is more necessary than ever. Therefore, dealing with new urban theories, each with the aim of solving urban problems, improving the quality and quantity of life of citizens in cities, improving the quality of the city environment, city management, advancing the city to become more desirable, and so on. , Is more important than ever. In recent decades, to solve these challenges and reduce its effects on metropolises and large cities, various solutions and perspectives have been proposed, one of which is to pay attention to the concept of resilient city. The present study is descriptive. - It is analytical and practical in terms of purpose. The statistical population of this study consisted of experts and professors familiar with the topics of the city. 35 university professors and experts in the field of research determined the sample size intended to complete the questionnaire. The results of this study showed that the criterion of physical characteristics of tissue with the highest D-R value (0.672) is at the top of the chart and shows that this criterion is the most effective criterion. Also, based on the calculated D + R value, the building quality criterion is the most important criterion. Also, the urban infrastructure criterion was considered as the most influential criterion due to the fact that it has the lowest D-R value.

Abstract
Industrialization and modernization of societies affect architecture, urbanization, environment, climate and geography; which we can mention the emergence of high-rise building, climate inversion, changes in geography of societies and environmental degradation. The roots of the problems over the last few decades are population growth, increasing migration to cities and metropolises, changes in needs and demands of citizens, etc.; Which faces urban managers, designers and architects with a huge challenge. The main purpose of this article is to theoretically study the uses such as residential towers on the one hand and the ideas mentioned in the theoretical discourse on the other hand with the approach of sustainable social development, and its impact on environmental protection according to the geography of Tehran. This research is "descriptive-analytical" in nature and "survey". It is "practical" in terms of purpose and "quantitative-qualitative" in terms of data. The number of statistical samples was 384 people and data were collected through questionnaires. Analyzes were performed in SPSS software. The most important result of this research can be expressed as the fact that due to population growth, high-rise was formed and through it, issues such as overuse of natural resources and fossil fuels, destruction of nature, reduction of social interactions, climate change, traffic creation, Rising air pollution, etc., has become a huge and insurmountable crisis.

Abstract
Buildings are one of the main pillars of social and economic development of countries that consume a large part of energy and natural resources. The share of this part of energy consumption is 30-50% on average. Also, in our country, based on the energy balance sheet of recent years, about 33% of the energy produced is related to the domestic, commercial and public sector, i.e. the construction sector. The purpose of this research is to investigate the effect of the location of the building on its energy consumption. The district of the research is the common 4 and 5-story residential buildings in District 5 of Tehran, on Ferdous Sharq Blvd. The descriptive-analytical research method is based on organizational and field data collection, by selecting 6 similar residential blocks and in different lighting positions, different data were collected. These 6 blocks are completely the same in terms of land area, infrastructure area, number of floors, heating and cooling systems and other characteristics, and the only difference between them is their location in a passage. Then, using simulation in Design Builder software, their energy consumption was calculated and compared. The results of the research indicate that the average energy consumption with an accuracy of 98%, the northern blocks, 7 261, the southern blocks, 11 247, the total blocks, 5 254, kilowatt hours per square meter per year, which is about 3 times the ideal building. . Northern blocks consume about 5% more energy than southern blocks. A block that receives light from 3 sides, north, south and west, consumes about 11%, more than the average, and a block that receives light from 2 sides, north and south, consumes about 5%, less than the average. North blocks, energy label D, south blocks, except for the end block that gets light from three sides, north, south and west, get energy label C, and as a result, south blocks generally perform better in terms of energy consumption.

Abstract
In order to understand the total consumption of buildings and accurately calculate how much energy each building uses, taking in consideration all the building's lifecycle phases is essential. In order to select the correct methodology for the main study, the researcher began with the determination and the parameters that would have been researched, as well as the analysis and comparison of the different methods used by other researchers to achieve similar goals. The following parameters define the final results and are stabilized or examined to determine their actual effect: A- Constant parameters: 1- Climate data 2- and data on the use of the building: B- variables: 3- Design data: 1- orientation 2- window to wall ratio 3- aspect ratio. This research uses a survey followed by a computer modeling methodology to achieve the goal of providing architects with techniques that reduce energy consumption in building units. To obtain reliable results that are useful to the construction industry in the country, the researcher has ensured that the virtual environment created in the modeling process mimics a typical building environment of Tehran units. Research has shown that passive design techniques have a major impact on the energy consumption of buildings. A significant reduction in consumption (67 percent) was noted when the orientation and percentages of the opening on the wall were changed. In summary, this study has shown that the application of passive, economical and simple design techniques has a major impact on the energy consumption of the unit rooms. If the architects take these ideas into account during the design process, the buildings will take on more responsibility for the environment and consequently reduce carbon dioxide emissions.

Abstract
In this project government endow loam to villagers for improving their houses. This project help to villagers for improvement their life and it help to villagers for preparation for sudden hazards. Improvement rural houses project improve quality of life villagers. Therefore, this project presents for resolving problems and challenges that improvement rural houses project confront with them. Investigative method was descriptive-survey and we used from questionnaire for collecting data. Statistical society includes 50 people that we used from census method for sampling method. Statistical method was technical supervisors in Kermanshah County. Reliability calculated by alpha Cronbach method that equal 0.72 and validity calculated by K.M.O and Bartlet method that equal (K.M. O=74/0) and Bartlet significant equal (0.0). But technical supervisors have positive attitude about housing foundation of Islamic revolution performance. They were satisfaction from workshops and upstream supervisors in housing foundation of Islamic revolution of province of Kermanshah. Results shows that there is relationship between distance village from city and quality of building materials quality. Also, there is relationship between knowledge of people about project and time periods. It shows that knowledge people increase. Finally, by factor analysis we understand that there are 5 components that effect on improvement rural houses projects that include: dimension of individual people and technical supervisors, attitude of people to improvement rural houses projects, life quality and improvement in life style, challenge in law and discipline and time of project. They explain 65.85% of total of variance. Also, the findings show that there is a meaningful and reverse relationship between the beginning of the technical observer's period and the amount of his attention to the consciousness of the people at the level of 0/05. Meanwhile, people's awareness has increased over time.

Abstract
In the contemporary century, with increasing development of technology, one of the challenges of contemporary architecture is to find its relationship with the culture. New technologies from industrialized countries with developmental goals are imported in an uncontrolled process. In contemporary Iranian architecture, technology has had a serious presence in various fields. The main purpose of the research was to investigate the cultural transformation of contemporary buildings in Tehran according to the application of technology. Due to the variety of types of use, this study focused on official complex compared to the two periods before and after the Islamic Revolution.The research method used in this research is combined (quantitative-qualitative). First, the components of technology and culture in accordance with contemporary architecture in the office buildings of Tehran have been developed by qualitative research method, then by quantitative research method, the relationship between key factors involved and the share of each component has been investigated. To examine the hypothesis, the relationship of three variables of culture, technology and architecture has been identified. In this study, cultural developments have been evaluated in two dimensions: mental and objective components. The results show that the effects of metamorphosis have had the greatest impact on the objective components of culture, including individual and social strata.Finally, the issue of technology application in contemporary office buildings in Tehran with a culture-based approach has been proposed in the form of a strategic model that will lead to the correct application of technology in office buildings in Tehran.

Abstract
High-rise buildings, by being recognizable in their context and signaling the introduction of urban integrity, have an impact on the perception and formation of citizens' mental image of the city. The present study examines the environmental perception of citizens in the interpretive, emotional, cognitive, and evaluative dimensions of high-rise buildings in Tehran’s 22th district as a case of study and emphasizes the formal, functional and semantic aspects of these buildings on citizen perception. The search system is intended for interpretive-structuralism research and the content analysis method (documentary method) is used in the theoretical section and the cross-sectional survey method. The population of the study consisted of 100 residents and non-residents of the area who are randomly selected. Data were analyzed by using SPSS software and Pearson correlation tests and one-sample T-test to evaluate the relationship between physical and semantic components in high-rise buildings perception and determine the importance of each environmental perception dimension.The results indicate that “the role of beauty of the form and shape of high-rise buildings” and “the amount of elevation congruence with the environment” in the first and second priorities affecting the level of citizens' environmental perception among physical and “The role of legibility and routing” as an effective factor among the semantic components in the perception of high-rise buildings has been based more on emotional and cognitive perception and less on the interpretative and perceptual dimensions of perceived citizenship.

Abstract
Increasing energy demand and environmental problems caused by the consumption of fossil fuels have made the use of passive solar energy methods more necessary, especially in commercial centers. On the other hand, the growth of science and technology in the world and the use of intelligent systems in buildings, has led to the completion of common methods. The purpose of this study is to investigate the role of the side wall of atriums and building intelligence in optimizing energy consumption in commercial centers of Tehran. Due to its nature, the research method is simulation with a case study and analytical approach and in terms of application type. In this research, first, the typology of the building form is introduced and the basic model is selected, and after selecting the design-builder software, validation and simulation of energy consumption in different scenarios are performed to determine the reduction of energy consumption in different situations. This research, which is taken from a doctoral dissertation, shows that the most optimal commercial centers in terms of reducing energy consumption in the climate of Central Tehran are related to atrium buildings without side walls. Also, the installation of smart awnings and light sensors at a control temperature of 22 degrees has significantly reduced energy consumption in these buildings.
Keywords: side wall, Building intelligence, atrium, Commercial center, Tehran.
