Determining Minimum Intervention in the Preservation of Heritage Buildings

Zhang, Yan / Dong, Wei

Heritage buildings serve an important role in transferring cultural identity. Where heritage buildings are physically degraded, damaged, or destroyed; can no longer function well; or require new design components, careful conservation is a key, ensuring that the original dignity of a structure is maintained. Therefore, the factors affecting the conservation require in-depth study. And, it is critical to identify the minimum intervention for preservation needed, as well as the levels of interventions. Only by clarifying the total number of intervention levels can we find the minimum level of intervention for an architectural heritage, which is the relationship between them. This research contributes a review of architectural heritage conservation issues, summarizes terms related to conservation practice. For those engaged in heritage conservation work, this paper offers all the interventions for architectural heritage and a model to find the minimum intervention for a project. The data from a literature review of existing studies, as well as examples of minimum intervention, have been investigated to provide insight into minimum intervention strategies. This paper provides a model for an architectural heritage conservation strategy, finding the minimum intervention level for a heritage building, and guidance regarding the decision-making process.
