The rebirth of educational architectural heritage plays an important role in the urban tourism economy, and studying the integration of educational heritage and tourism is of great significance and value. This article selects the educational heritage in Nanjing, China, from 1840 to 1952 as its research object to explore the integration and sustainable development relationship between heritage utilization and tourism. This article adopts a research method that combines qualitative and quantitative methods. First, it collects historical data and conducts on-site surveys to obtain information on 117 important educational heritage sites in Nanjing. Then, it uses ArcGIS technology to quantitatively analyze the evolution rules of modern educational buildings in Nanjing and the spatiotemporal distribution characteristics of the heritage. Finally, a cultural tourism strategy is proposed based on heritage characteristics and government policies. The research results reveal the interdependence and sustainable development relationship between the protection and utilization of educational heritage and tourism: according to the distribution characteristics of the heritage in the urban space, the "educational heritage tourism path" of the ancient city is constructed, which can promote the development of urban tourism. Subsequently, the economic value created by tourism is used to "feed back" heritage protection. This research result provides reference for educational heritage tourism in other cities in China and around the world.

Ginling College is the first women’s college founded by the American Christian Church in Nanjing, China, in the early 20th century. The architectural style of the school reflects the orientation of the “Chinese localization” of the Christian Church at that time. It is a representative work of the revival of traditional Chinese architecture. It is known as a “Renaissance of Chinese traditional architecture” and profoundly influenced later generations. Due to its important historical status and artistic value, the Ginling College complex has been designated by the Chinese government as a national key cultural relic protection unit and China’s 20th-century architectural heritage, and the protection scope of the Ginling College historical district has been specially designated for overall protection. Currently, little research has been conducted on this historic area, so the authors undertook this project. This paper adopts a combination of qualitative and quantitative methods for research, starting from the two aspects of architectural art and sustainable design, and analyzes in detail the artistic characteristics of the project, the structural materials obtained locally, and the sustainable design method that utilizes natural lighting and ventilation to explore a modern campus design method based on the concept of sustainable design with a “combination of Chinese and Western architectural art”. Through artistic creation and technological innovation, traditional Chinese revival architecture has realized a harmonious coexistence between man and nature, embodying the design concept of sustainable development, and promoting the development of architecture and the region.

Rapid advances in technology have led to an increasing demand for this type of information in the field of cultural heritage and architectural conservation. The article aims to use digital technology to obtain, record, store, and display accurate and intuitive information about architectural heritage for daily management and repair of that heritage. This article conducts a comprehensive and in-depth study of the pathology information from the James Jackson Gymnasium, a typical case of the modern educational architectural heritage of Wuhan. Research contents include obtaining point cloud data through 3D scanning, constructing Building Information Modeling (BIM) 3D models and pathological information models to visualize the affected parts, using the Monument Damage Diagnostic System (MDDS) to establish a pathological information map management system, using virtual simulation technology and digital repair technology to diagnose and repair the affected parts, and establishing a systematic architectural pathology information database to explore the causes of architectural pathology from a multidisciplinary perspective. The authors aim to gradually promote this method and build a systematic pathological information database of architectural heritage. This utilizes the sharing characteristics of information technology to transcend the barriers of time and space and provide important support for heritage protection and pathology management. The Architectural Pathology Information Management System is proposed as an innovative solution to promote the sustainable conservation of architectural heritage through digital technology.

In the face of the increasingly deteriorating global environment, the sustainability of building systems has become a major research topic. This paper presents sustainability research on large-scale building cases from the perspectives of ecological emergy value and carbon emissions. Specifically, by calculating the emergy value and carbon emissions throughout the entire life cycle of the building system, a quantitative analysis of sustainability based on the LCA–emergy–carbon-emissions framework is completed. The results indicate that from the perspectives of both emergy value (over 80%) and carbon emissions (over 90%), the operational stage and the building-material-production stage are the controlling factors. Retrofit design strategies help enhance the sustainability performance of the building system, but different types of design strategies have different effects. The landscape-transformation-design strategy (strategy A) significantly improves the ecological sustainability of the building system, the equipment-improvement strategy (strategy B) helps reduce the carbon emissions of the building system, while the infrastructure-renewal strategy not only has a weaker impact on sustainability improvement but also generates the highest carbon emissions. Additionally, with the aim of controlling carbon emissions, the integration of solar clean energy sources contributes to the overall sustainability of the building system, providing references for architects and building managers.
