Abstract
Abstract Prefabrication in construction industry can probably reduce the cost of waste. In this research, the advantages and disadvantages of prefabrication and its eco-efficiency were identified; then the development strategies of this industry were reviewed. For this purpose, the questionnaires were used to select the proper sub-systems for prefabrication. The Delphi Snowball method was applied according to experts 'opinion, and these questionnaires were identified and adopted. Then the effect of prefabrication on nonstructural components was examined on the extent of waste reduction. Consequently, the results revealed that prefabrication may reduce the cost of waste by 97.54% and the total cost of the project by 5.06%, and environmental efficiency was estimated as 99.2%.
