Studying the Impact of Multi-Functional Architectural Approaches on Adaptive Reuse of the Industrial Architecture Heritage of Tehran City

This urban issue of terminating and ignoring such buildings as heritage of industrial architecture has caused the closure of this constructions, in spite of having an applicable life cycle and architectural principles; however, by some reactions from various institutions and to promote economic and social sustainability, the condition for having a new application and restoration these industrial buildings as a heritage is provided, which are examples of the experiences of adaptability in Iran as the main focus of this research. Therefore, the aim of this research is to review the successful experiences of multi-functional and universal adaptable architecture to compare their strategies with the heritage of industrial experiences in the city of Tehran. In this research, the studies of adaptability for universal samples are considered as the basis for exploring the multi-functional architectural strategies. The approaches include three physical layers of the building structure, facilities and facade, which have been evaluated by using Delphi method on the heritage of industrial architecture in city of Tehran as a statistical population. The non-parametric statistical tests of Cochran's Q test and Friedman's test, were applied to analyze data; the theoretical sampling method for both statistical population (Tehran's industrial architectural heritage) and (relevant experts) was adopted. According to the expert’s ideas, the strategies of two-layered structure and facade in the target buildings were confirmed; according to the data analysis, ‘Argo Factory’ had the highest Degrees of Freedom (df) regarding the structure layer, and in relation to the facade, the ‘Iranian Artists Forum’ with the highest average test rank, showed the highest conformity of the facade and the structure. However, regarding the facilities, no compliance of the facility was found. The industrial architectural heritage of Tehran includes some buildings that reused for another purpose as: Argo Factory (changed to Argo Contemporary Art Museum & Cultural Centre), Iranshahr Barracks (Iranian Artists Forum), Beryank Hosiery Factory (Haftchenar's Museum of Wildlife and Natural Monuments) and Qasr Prison (Qasr Garden Museum/ Museum of the Qasr Prison). The target buildings were ranked according to the data acquired by calculating mean rank for the strategies were applied for each layer. According to the results, two characteristics were found in the industrial buildings that can highly affect the adaptive reuse of the heritage of industrial architecture, 1. the concentration of the structure at the lowest points and limited spaces with more free spaces compared to its counterparts, and 2. the adaptation of the building facade to the structure.
