VALUE ASSESSMENT AND RENOVATION DESIGN OF BUILDINGS IN THE PERSPECTIVE OF URBAN RENEWAL: CASE STUDIES IN CHINA AND ITALY

In the process of rapid urban development, as the economy develops and the scope of the architecture continues to expand, buildings face the serious problem of conservation and renewal, adapting to contemporary needs has become the direction of development of architecture. At the same time, as a cultural carrier of the building needs to be renewed, not only become an important way of sustainable urban development but also will the creation of architectural renovation design provides an opportunity, this thesis on the urban renewal of such a social context of the perspective to explore the renovation design. Urban renewal promotes the renovation and regeneration of existing buildings. In order to improve the function of existing buildings and match the current situation of the surrounding area and enhance their value, the content of renovation and regeneration involves the accurate assessment of the value of existing buildings. Generally speaking, architects rarely carry out a comprehensive value assessment of a building before carrying out a renovation design but basically carry out an analysis of pre-design ideas after obtaining basic data, that is, directly into the design stage. The primary prerequisite for the renovation design ideas advocated in this thesis is a comprehensive and accurate value assessment of the building, and the establishment of an accurate and applicable value evaluation system is also an effective method for determining the value of the building. This thesis also expresses that when researching an object, a qualitative analysis of its value composition and characteristics should be carried out first, on the basis of which an assessment system applicable to the object is constructed, a quantitative assessment is carried out, and on the basis of this assessment, recommendations are made for the grading of the research object. Finally, based on the grading results, the object should be designed for renovation and a more reasonable renovation plan should be proposed. Due to the complexity of the object of study, four different cases were chosen to describe the value assessment and renovation design, without assigning the value assessment and renovation design to a single case. However, this is sufficient to demonstrate that it is necessary and important to assess the value of the target before the renovation design is carried out. This thesis follows the logical relationship of posing a problem, analyzing the problem, solving the problem, and drawing a conclusion. Chapter 1 is about the background of the thesis and the purpose and literature review, the necessity, urgency, and feasibility of establishing a value evaluation system and renovation design under the perspective of urban renewal. Chapter 2 is about the value evaluation of a historical ancient village in China using the entropy weight method, and also the spatial analysis of the village, which yields the protection level obtained by each building in different locations of the village, thus giving a reference for renovation design. Chapter 3 combines artificial intelligence techniques in order to improve the efficiency of conventional value assessment methods, using GA-BP neural network methods to assess the value of a Chinese village and then derive the different grades. chapter 4 is a study on the application of HBIM technology to the renovation design of a church in Italy, mainly describing how this method has helped the renovation design. Chapter 5 is the application of TLS technology to the design of a Chinese shop interior renovation project, expressing how this technology can be integrated into the design and how it can be updated in real-time, resulting in a collaborative design. Chapter 6 is a summary of the thesis and a description of the sections that need improvement and continued research in the future.
