Investigating the behavior of agents in the housing sector, including investors, households and developers, is very important. A large part of housing price fluctuations is caused by the activities of these agent, especially the investors in this sector, and these housing price fluctuations influence other economic sectors because the housing sector has a lot of backward and forward relationships with other sectors. This research aims to analysis of the behavior of agent in the housing sector in the forming of the equilibrium pattern of housing prices in Iran using the mathematical optimization method for the period of 1991 to 2022. The results show that there is a positive relationship between the equilibrium price of housing with the construction cost of each residential unit, household income and investors' expectations of housing prices. Also, there is a direct relationship between the volume of trading of investors and their expectations of housing prices. When the expectations of housing prices are in the range of zero to 1.71 and more than 1.71, investors will be in the position of selling and buying housing, respectively. Hence, the relationship between the equilibrium price of housing and the volume of trading of investors with the risk component of investors is positive, and if the equilibrium price of housing is more (less than) 2.33, investors take a selling (buying) position. On the other hand, if the investors are in the low range of zero according to the amount of risk and volume of trading of investors, then the investors are in the selling position and if they are in the upper range of zero, the investors are in the buying position.

The contemporary living crisis that is rooted in disconnection from historical period and context culture has led to a housing crisis, the sign of which can be seen in the changed quality of life of residents living on newly-built fabrics. This qualitative level results in some differences between these two fabrics, which may reduce the mental and social security of contemporary residents. In this research, the null hypothesis assumes that the study of historical fabric and comparing it with the contemporary era are proper contexts used to create security in residential structures. Hence, this study aims to recognize the values available in traditional housing using effective components to provide some strategies to cope with this crisis. The present paper investigated the security rate of individuals comparatively and then identified the factors affecting housing quality. Comparison between houses located in Dezful was done based on the Kerry Walk method, and security was examined using field observations, a survey in the fabric, and library studies. Moreover, the research test included measurement of household weight based on the Entropy-Shannon method and data assessment based on the Vicor Analytical Model in two considered fabrics. Finally, the deductive logic method was used to reach a conclusion and propose some strategies to improve the quality of architecture. Studies indicated that the security rate (71.4%) in traditional housing satisfies the need of residents more than its value (28.6%) in the contemporary era. Although some security-creating variables exist in contemporary housing, security-providing indicators in this housing include visual and environmental comfort, spaces' legibility, economy and income level of households, monitoring and surveillance, privacy, space's dimension, and space perception.

The need for housing is one of the most basic human needs. According to the principle thirty-one constitution of Islamic Republic of Iran, having adequate housing is the right of every Iranian individual and family. The qualitative indicators of housing has always been the most sensitive instruments are accommodation plan. In other words, Muslims should be chosen home layout, which allows the growth and excellence of the individual, family and society based on Islamic beliefs provide. In this context, the principles of Islam has provided guidance in order to achieve the desired quality of housing. The research aims is to answer the basic question that is created: Which factores of quality of traditional architecture can be used due to changes in the conditions of society and the way people live, to lead to Islamic values in contemporary housing. Accordingly, Article is a qualitative study and For the final evaluation of the Analytic Hierarchy Process data is used. Gathering data on the basis of lists for interview techniques, questionnaires, have been observed. In this way, the documentary and library and map analysis has been used. Results and findings can be categorized in three parts o Extraction The Islamic concepts related to housing in the model of islamic optimal housing o Extraction architectural design patterns of traditional housing fits with this model o Prioritization patterns based on contemporary Muslim needs.

Islamic architecture of Iran, due to its reliance on the principles and spiritual beliefs and Islamic ethics of the people of this land, can be used and exploited in the deep definition of the theoretical constructions of a progressive Islamic architecture, suitable for the modern needs of contemporary housing. Therefore, the re-examination of the hidden spiritual teachings and Islamic ethics in the art and architecture of the past housing is one of the most fundamental steps in this field. The present article, with a descriptive-analytical method, seeks to determine effective architectural design strategies in strengthening the concepts of Islamic ethics among housing users by looking at contemporary housing architecture in the city of Ardabil with Islamic origins. Data collection was achieved through survey and library studies. The statistical population includes residents of the central part (region one) of Ardabil city with a sample number of 384 people with Cochran sampling. Data analysis was done by the least square method with the help of SmartPLS.3 software. The findings of the research showed that the principles of housing architecture should be functionally; cultural; Economic; spiritual; environmental; legal; psychological; And semanticism should conform to Islamic ethics. In addition, the greatest impact is related to psychological structure and spiritual structure. The results of the research are presented in the form of solutions in the field of placement of the building in the neighborhood unit, in the way mass and space coexist, spatial and functional organization and arrangement, components and furniture and decorations.
