Buildings have a significant share of global energy consumption and a major role in global warming. Buildings also affect the temperature of their surrounding environment. This paper investigates the effect of Floor Area Ratio (FAR) and urban block configurations on energy consumption, urban microclimate, and outdoor thermal comfort in Tehran with a hot climate, using the simulation method and Ladybug Tools (1.6.0). According to the results, decreasing FAR in an urban block improves urban microclimate while reducing building energy consumption. The results reveal that the effect of FAR on the buildings' energy consumption is more considerable. Decreasing FAR reduces the buildings’ energy consumption and outdoor air temperature. Furthermore, the scattered form of urban blocks consumes the highest cooling energy while having the lowest heating load. The lowest cooling and heating loads are found in the linear and scatter organizations. Considering the dominant cost of cooling energy, the case with less FAR would be the best choice from an economic point of view. For three-story urban blocks, the best case is the courtyard form, while for five and nine-story urban blocks, the best option would be the linear form.

There are many evident that people are more interested in walking in attractive urban spaces and inappropriate physical and psychological condition can reduce their presence in a remarkable amount. The current research investigates the influence of physical design and psychological elements and their criteria on selective physical activity and specifically walking in urban public spaces. However there are some limitations in determining specifications of physical and psychological design which have effects on walking, meanwhile the urban planning elements, transportation and crime prevention via environmental design are developed strategies which have potentials for influencing the rate of pedestrian-oriented state of urban spaces. The research frameworks which are extracted from the complex of these elements include 5 applied criteria of safety, aesthetics, destination and (environmental) security which are specified by use of documentation and library method. In this paper, the public general spaces of Farahzad village were selected by field study and by help of questioning technique which its statistical community included 12 urban planning experts, the mentioned criteria were analyzed by Analytic Network Process. The results indicates that the quality of physical design and the psychological elements have major effect on pedestrian-oriented state of urban spaces and the importance degree of each criterion in determining the rate of pedestrian-oriented state of urban spaces of Farahzad village included the aesthetics, security and applied indicators in a value level, destination and safety. Meanwhile, the most pedestrian-oriented spaces of Farahzad village were specified by considering the mentioned criteria and by use of Analytic Network Process. Cognition of this issue will help the above-mentioned options to overcome their challenges which are creating attractive and dynamic urban space via improving the condition.

Today’s housing, as a private realm of human life, has changed in comparison with the past which was made regardless of quality, desirability, and lack of paying attention to the human needs and its psychological consequences; That is to say, residential units have turned into a set of closed spaces and their open and semi-open spaces have been merged into the urban spaces which disrupted their fundamental functions. In such a situation, reviewing and paying special attention to these spaces together with closed spaces in Tehran is really necessary. But this question is proposed that what are the indicators affecting the quality of open and semi-open spaces in contemporary housing? And how much do they affect the quality of these spaces? This research has a mixed (quantitative-qualitative) method which is applied in terms of purpose, and in terms of data collection method it is of descriptive-analytical and survey type. The statistical population includes 380 inhabitants in residential apartments in the Zafaranieh neighborhood of Tehran. After collecting field information through the questionnaire, the indicators affecting open and semi-open spaces, including: functional, behavioral, physical, environmental, social and perceptual-semantic by using statistical analysis software were analyzed. To investigate the significance of relationship between the mean difference of the scores of the effective indicators, the one sample T-test method and intragroup one-way analysis of variance have been used; the results obtained from the research showed that in the open and semi-open spaces of residential apartments in the Zafaranieh neighborhood, the physical, environmental and behavioral indicators with the mean score of 4.17, 3.52 and 3.22, respectively, have somewhat more favorable and more appropriate situation than other indicators, and currently their efficiency ratio is at moderate limit. However, the functional, social and perceptual-semantic indicators with the mean score of 2.68, 2.57 and 2.21, respectively, are in an unfavorable and inappropriate situation, and their efficiency ratio is at weak limit.

Political stability and economic security have led to forming small and independent agricultural units in different regions of Iran in a period. They were shaped by combining water with residential, religious, service, and agricultural elements and are referred to in local communities as the "Farmstead" The historical documentation recorded their presence from the 4th century AH until the Safavid era from an economic and jurisprudential approach. Then, domestic and foreign elites introduced them in the form of books and travelogues in the Qajar era; however, they did not mention the architecture of the farmsteads and their features.  in 2008, for the first time, some Farmsteads are introduced by field surveys in Niasar, and the qualities of their formation and structure are considered by publishing papers. The Landlords have built them with two types of agricultural castles and agricultural complexes. In addition, they have determined the location of farmstead by water resources, and their formation was subject to economic and security equations.
The main research problem is insufficient knowledge of the historical farmstead of Iran in the national and international communities. These monuments are ruined due to various reasons in a period, and eventually, the people have forgotten their names.The current study aims to introduce the historical farmsteads of Iran by investigating their past and present status and A main question in this research is: What are the physical and functional characteristics of Iran's historical farmsteads? according to this,The interpretive-historical method is used to read the written documents and survey their historical propertise to reach the research aim  and question. Thus, interviews with farmstead dwellers observation and review maps of historical monuments, and library studies to examine written documents constitute research tools.
These farmsteads were studied in the central plateau of Iran, especially in the cities of Kashan, Qom and Yazd. Some of them were known as castles until now. But in this article, by examining their physical and functional characteristics, it has been determined that they are farmstead and in addition to agricultural land and water, they have physical elements such as Castle, mills, water reservoirs, baths and mosques. Thus the Castle has been a part of the farmstead-related elements. they also have social, cultural, and economic systems. The current research can help to register farmsteads in the list of national monuments of Iran as an independent collection.
