Investigation of New Construction Technologies in Terms of Efficiency in Iran and Selection of the Best Method Based on FAHP Fuzzy Hierarchical Analysis

In the current situation of the country, the most important necessity is the use of new construction technologies due to its important role in sustainable development. Higher manufacturing speed than traditional methods has made it possible to prepare more units for operation in less time. The purpose of this research is to study new construction technologies in terms of efficiency in Iran and to select the best method based on FAHP fuzzy hierarchical analysis. The research was applied in terms of purpose and descriptive-survey in terms of data collection, and the research data were analyzed using a hierarchical method. The data collection tool in this field research is a questionnaire. The statistical population of this study was members of the Yasuj Building Engineering System Organization. Random sampling method was used. Morgan's table was used to estimate the sample size, which is equal to 100 people. The results showed that the most important factors in the study of new construction technologies in terms of efficiency in Iran and selecting the best method from the strongest to the weakest, respectively, are the priority of green roof technology, durable frame system, nano building coatings, biological concrete, windows and walls. Thermochromic, cold rolled light steel frame system, two-shell facades, solar panels and trade panels..
