Investigating the principles of industrial heritage reuse plan by analysis of international documents - case analysis of Shiraz textile factory

The principles governing the reuse of industrial heritage aim to preserve its key features. However, there are various interpretations of these principles when it comes to the design process. This study utilizes international documents, specifically ICOMOS charters, as a source for extracting goals, policies, strategies, and design solutions related to changing the use of industrial heritage, adopting a combined quantitative and qualitative approach and logical reasoning method. By analyzing the content of the charters and recommendations, as well as the frequency of keywords related to landuse change, thirteen categories were identified , including integrity, authenticity, value, people-society, historical aspects, collective memories, tradition and characteristic, tangible-intangible aspects, culture, economy, spirit of the location, and the connections between them. For example, the goal of preserving the core values of the industrial complex within the value category leads to the identification of common patterns in both the tangible and intangible aspects of the works. In terms of economic policies, emphasis is placed on enhancing economic productivity for the benefit of the local community. When discussing traditions, an important strategy is to utilize the physical capabilities and visual values of the heritage as a source of inspiration for the new design. Identifying the character of the work involves considering elements such as the structure type, coverings, decorative style, materials used, furniture components related to the production line. Furthermore, maintaining the ability to host events and activities that took place during the active phase of the complex helps establish a connection between people, society, and industrial heritage. These components represent various instances that have been derived from international documents and provide different levels of activities related to the land-use change, as explored in this research. A quantitative analysis was conducted to examine the "communication network" among these categories as a foundation for resource management. The results highlight relationships between goals, policies, strategies, and solutions across different categories. For example, preserving the values of the heritage requires interaction with aspects such as "completeness" and "tangible and intangible entities". The decisions in the field of "people and society" are closely related to "authenticity", "collective memories", "economy", and "value". The volume of the communication network in the value category has the greatest impact on other categories. To demonstrate a practical application of the identified categories and the hierarchy of goals to solutions, the reuse plan of Shiraz textile factory was examined as a case study. The findings of the study revealed that the land-use change plan for the Shiraz textile factory included 14 practical actions related to value, 12 actions related to importance, and 11 actions related to collective memories. The remaining categories had a range of actions ranging from 2 to 7. Based on these actions, the land-use change plan received a score of 75.06%, indicating that it is considered a successful case of change of use. Overall, the model presented in this research can aid in designing according to the principles of industrial heritage protection and serve as an evaluation toolfor analyzing land-use change plans in alignment with international documents.
