One of basic principles in designing treatment environments is to design air conditioning/ventilation system proportionate to environment. Essentially, appropriate air conditioner in treatment spaces must bear the following capabilities: providing healthy and clean air, reducing the concentration of pollutants produced in the atmosphere, emission of pollutants and impeding their spread in exterior space. Due to significance of the foregoing items in designing treatment spaces, in this research which has been conducted by descriptive-analytic method and using library studies, exامینation of hybrid ventilation system in treatment environments have been dealt with. Designing air conditioners in hospitals include ventilation design methods in form of natural/passive, mechanical, and hybrid ventilation systems. In this research, innovative design approach of hybrid ventilation system of hospitals have been introduced; having studied architecture of Iranian windtowers and greenhouse behavior of building façade and advantages and disadvantages of this system and superiority of the proposed system have been addressed. The system will be designed by using triple-walled shell (for the purpose of heating in winter season and airflow circulation in summer season) and cooling tower (plan design by viewing a vertical space in overall volume of the project and having direct access to AHU Rooms) A considerable advantage of this method is to reduce amount of energy consumption and subsequently decreased suction fan rotation period in cooling tower system as well as energy consumption reduction for heating air via fancoil.

Urban spaces refer to the man-made spaces which possess a special order for human behavior and activities. One of these spaces is the surrounding space of public transportation stations. The subway stations, although potentially encompass many different groups of people; few social interactions take place in these spaces. In this regard, by making the surrounding areas of the subway stations be pedestrian-oriented, the potential for increasing the socialization capacity of the mentioned spaces will be provided.The Sadeghieh Subway Station can be considered as the most important subway station in Tehran, which on the one hand is the rail port of Tehran’s western entrance, and on the other is the port for railway journeys inside the city. The main concern of this study is to assess the success or failure of the interventions made by the municipality for changing the surrounding area of the Sadeghieh Subway Station into a pedestrian-oriented space. The method used in this study is surveying, in which the data were collected using a questionnaire and interview. The study’s population is all people who use Sadeghieh Subway, and the sample size for the study were considered 140 subjects.The results shows that after the municipality’s actions to change the space into a pedestrian-oriented space the district have a progressive process in such cases as transportation, security, Pedestrian infrastructure, vitality and attractivity rate to remain in the space, the amount of traffic crossing the sidewalk, walking group, the lighting, the vendors, the cleaning, pavement structure and climatic elements. but in such cases as mix use, recreational activity, readability and design furniture no significant change was seen, and in some cases the results were counterproductive.

With the arrival of cultural factors and design patterns of other countries, Especially in western countries, culture and the identity of the Iranian community, there has also been a change; Therefore, today the discussion about identity and cultural factors has been considered in various scientific branches. Since one of the methods of studying the identity of a society is the attention to the elements of space organization and its relation with the culture of society, In order to identify the identity of the traditional Iranian society, the study of cultural identity elements and design patterns in traditional Iranian architecture seems to be a good way. This article is sought after to identifying components in the traditional architecture of Iranian houses and examine the appearance of identity elements in the traditional architecture elements of houses in Iran. The combined research methodology includes descriptive, analytical methods of case study type. In this way, the subject of research has been studied using field observations and library studies. At the beginning, a definition of identity and Identity creation was given in architecture, and then a sample of these traditional houses called Sheikh-al-Islam house was studied. And the result of this study shows that in the design of traditional Iranian houses, the architect is familiar with the identity elements, for example, national and religious values ​​and so on.
