A model approach for post evaluation of adaptive reuse of architectural heritage: a case study of Beijing central axis historical buildings

Abstract

The adaptive reuse of architectural heritage is the basis of embodying its core value, bringing new life to heritage architecture, and is an important way to integrate it into contemporary development. In many current studies, the adaptive reuse of architectural heritage focuses on the research framework of adaptive reuse and the most effective method for adaptive reuse of a certain building. In the whole process, the post evaluation strategy of adaptive reuse based on specific cultural background is ignored, and the adaptive reuse of heritage buildings is a dynamic process. Therefore, this study takes 9 heritage sites along the central axis of Beijing (including three types of single buildings, architectural complexes, and historical and cultural district) as examples. The 25 factors affecting the adaptive reuse of architectural heritage are extracted by the literature retrieval method, and are divided into three categories according to the content: existing fabric, spatial character and policy and value. Then the analytic hierarchy process and fuzzy comprehensive evaluation are used to calculate the factors of 9 heritage sites in matrix, and finally obtain the reuse score of each heritage site. The results show that Meridian Gate has the highest comprehensive score for reuse in single buildings, the Forbidden City has the highest score for reuse in building complex, and Qianmen Street has the highest score in historical and cultural district. This study provides post-evaluation methods and strategies for the adaptive reuse of architectural heritage. Finally, a post-evaluation framework for the adaptive reuse of architectural heritage is formed. Finally, a post-evaluation framework for the reuse of architectural heritage against a specific cultural background has been formed. In the future, the status of the reuse of architectural heritage can be evaluated to maintain its proper authenticity, integrity and sustainability at any time. It can also guide the relevant decision-making before the adaptive reuse of architectural heritage and the optimization process after the adaptive reuse of architectural heritage.
