The values of cultural heritage can be considered as a key word in interventions in conservation of cultural heritage. Nowadays, the role of value in various fields of heritage, especially in architecture heritage, is one of the most important factors that affects the concept of conservation. Along with and related to the concept of value, lies the concept of conservation, one as old as human history. Due to variety and differences among values in different societies, conserving these values has to precisely identify the needs in each society without which it is not possible to carry out an accurate conservation. This study aims to determine the relationship between the hidden values of architectural heritage in Iran and the ways of conserving them, and by assuming that there is a direct relationship between them, this study attempts to explain this relationship and introduce various kinds of values and ways of conserving them. Analyzing ways to recognize, assess and apply these values in conservation is another section of the studies that provides the preparations to make a suitable model to conserve values of architecture heritage in Iran. The main purpose of this thesis is to obtain a model based on which we can find ways of conservation regarding the values in architecture heritage. This model, known as the value-based model, makes suitable the conditions to extract, assess, and prioritize various values in architecture heritage; it also makes the application of the values possible in order to make appropriate methods of conservation. According to the proposed model in world heritage of Takhte Soleiman and ANP and Delphi method utilizes techniques to extract hidden values in this set the outcome of the project makes it clear that the application of the model resulted in a better decision making process in the field of conservation, and this can make a good opportunity to codify a charter of architecture conservation in Iran. Research is the method of data collection, documentary and field.

Infill architecture has always been considered as a practical approach to creating new structures to provide usable spaces in historical textures, which in addition to meeting the needs of the contemporary era and strengthening the intrinsic values of a place, also plays a key role in the development of these centers. This approach, which originated from urban development trends, can also be used as a design keyword in the historical textures of villages. Thus, this study seeks to answer the question of how to intervene in the historical and traditional texture of historical villages according to the infill architectural approach. Assuming that the application of the model can affect the effective multifaceted factors on the design in the rural texture and without its application, many important and necessary components will not be included in the process, which can cause problems in this regard. The main purpose of this research is to obtain a model agenda for planning the design of infill buildings in the texture of historical villages and its application in a case study. This study is descriptive-analytical research. The most important findings and conclusions of the research are the presentation of the design agenda model based on the principles of infill architecture in the texture of historical villages which after assessing the situation and analyzing the data based on comprehensive physical information, architecture as well as formal, environmental, climatic patterns and interpretation of the new building plan, is introduced. In order to assess it, this model was used to design ecotourism and tourism accommodation in Sopurghan village of Urmia city. This research has achieved qualitative results through the application of quantitative methods, which in addition to preserving the valuable architectural heritage of the field and in harmony with its nature, can also play a significant role in economic, social and environmental prosperity and provide local resources in these centers and preparing a suitable platform for design in other valuable villages.
