Light is one of the many wonders in the architecture Iranian houses. It is a major tool for space creation and design. An important consideration in the Iranian architecture, which takes a functional and conceptual approach to the extensive subject of light, has been that light should create a beautiful and spiritual space in addition to being functional. The light used in a house should be pleasing to the eye, and it should not be dazzling or bothersome. Optimal use of light plays a major role in creating mental peace and physical comfort and saving energy. This paper investigates different methods of exploiting natural light in the architecture of Iranian houses. For this purpose, three houses of historical interest in the city of Kashan in Iran (Boroujerdi-ha, Tabatabaei-ha, and عباسian) were studied for the position and role of natural light in them. A qualitative research method was used within an analytical-interpretative approach. First, the elements and components used to exploit natural light were studied, and then the strategies employed to manifest values, meanings, and concepts were explored within an analytical model.

Islamic and Iranian cities, both, East and West, know the physical monuments of Islamic culture1 based on one of the features of the Islamic cities. Meanwhile, other religious centers, including Tkaya, Hosseiniyehiyeh and hospice is not the case to considerate, while these elements cause to shape group behavior, strengthen social ties and strengthening of cultural integration, have always played a major role. These reasons reflect the role of the religious and their religious mission to, Imam Hussein: have been lasting and eternal ever. On the other hand, religious buildings, including mosques, Hosseiniyehiyeh, the convent, the grave and so for various reasons such as “governing their spirituality,” “Historical Background”,“architectural style” and “cultural works - social among people of the past had been of special aspects “sanctity”. Materials and Methods, “descriptors” and “analytic” in addition, with reference to theories and models of sustainability and sustainable urban spaces using “argument” and “analog” to review these theories and extend them to Hosseiniyehiyeh and Tkaya discussed and some results in this direction are mentioned. Research findings show the survival of Tkaya and Hosseiniyehiyeh beliefs, beliefs, customs and religion of citizens, especially their integration with the components is related to religious values and reflecting the traditional city is based on the formation of beliefs is that survival, Protection and maintenance Hosseiniyehiyeh paid actor and in which viewers of this show and passionate Hosseiniyehi mourning single entity to have formed; If due to the impact of beliefs and opinions of people throughout history has been a Hosseiniyehiyeh as a phenomenon of religious values and that its inclusion has been persistent throughout history and reflect the beliefs of religious people and the world towards Imam Ali, Imam Hussein: future date will remain the eternal.

Building construction challenge, in recent years, is the reduction of social, economical and environmental impacts along with economical nature and increasing life quality, as here sustainable construction is important. Pre-fabrication and industrialization are referred as a solution of sustainable construction due to some of its main characteristics consisting of many sustainability aspects. Due to this fact, the application of these building systems in most cases, makes achieving to sustainable building more easy. Sustainability aspects in industrialized systems are categorized in four groups of environmental, social, economical and technical issues and in each group some of general characteristics of industrialization in these methods are studied. Today, industrialized construction systems by relying on quality increase idea and blending with the environment and more flexibility, good design and planning and optimization, can fulfill the goals of sustainable construction.

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.

Earth-Shelter construction is one of the aspects in architecture where the thermal mass of the earth behind the outer walls are applied in order to reduce heat loss and keep the internal temperature at human comfort range. In case of earth-shelter buildings, housing is especially important. As for its applicability the earth-shelter provides good housing. Typological studies of earth-shelter construction in Iran by introduces various Iranian examples of this type, could be a model for the today’s innovative designs with an approach to energy saving. This type of construction responded to human comfort requirements when modernism was absent to claim that it could do the same through mechanical technology. The study method adopted here consists of qualitative-descriptive and deductive analyses. The categories of earth-shelter architecture are three worldwide: Earth Mound, Rocky or In-Hill and Bellow ground. Here the genotype of earth architecture and phenotype of earth-shelter are studied in details. The same is of two in Iran: Rocky, which is divided in continues and discontinues types and closed underground type. Studies conducted in Iran have revealed a new type of these structures named Combined Continues Rocky open Underground by the author.

Looking from an historical perspective, it can be seen that many civilizations have lived in the country and consequently produced many different cultures and architectural products. One of the oldest cities which contain such historical examples which have lived until present is Tabriz. Its traditional houses are the most important places to represent the life style of the past. Lack of recognition and appreciation of these buildings by authorities and the public will gradually lead to their destruction and replacement by contemporary buildings. The present study seeks to introduce specific architectural features of traditional houses in Tabriz. Preservation of the features of these houses helps maintain the architectural heritage and culture of the region. Most old houses in Tabriz were reconstructed at the beginning of the Qajar era after a devastating earthquake in 1780. The destruction caused by contemporary constructions, in the chaos of modern period, makes it difficult for researchers to gather information about the principles of traditional buildings and to identify their typology. The survey is a compilation of a process in the typology of 52 traditional houses of Qajar and Pahlavi periods in Tabriz. The study revealed that it is possible to accomplish the classification of the monuments with the application of a quantification process in which the qualitative data related to architectural elements was successfully converted into quantitative data by assigning numerical values and using coefficients.

What is called the problems of Tehran metropolis now a days, is deep- rooted in the policies ofurban planning in our country. Since not far past up to now, immigration from all over the country to Tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most areas which get erosion very quickly due to not being benefited from minimum constructional standards, service and urban infected organ are all those problems that a city such as Tehran is confronted with. These cases caused that the greatest growth center of the country loses its capability of attracting the possibilities and parameters needed for efficient development and due to heavy pressure imposed by other towns and villages, this city is now suffering from serious problems which only by allocating extra budgets and additional funds, may be temporarily decreased. The topics which will be discussed in this article are those problems arisen from immediate neighborhood of two heterogeneous fabrics which have not been properly paid attentions to. So it has been tried in this article to address the heterogeneity in Tehran, caused by economic and social problems. In this article different aspects of the issue from urbanization viewpoint with analytical approaches and the existed challenges have been addressed.
