Research on Activation and Functional Remodeling Strategies of Existing Campus Space in the Context of Urban Regeneration

As urban development in China shifts from incremental expansion to quality-driven stock optimization, the renovation and upgrading of old school buildings have become vital for improving urban functions and preserving historical contexts. Taking the comprehensive renovation of the Nanjing Sports School as a case study, this paper explores full-chain strategies for the revitalization of existing campuses from the perspective of design management practice. Drawing on the “Urban Physical Examination” concept, the study implements a pre-diagnostic framework consisting of “comprehensive evaluation + thematic assessment + professional testing” to accurately identify core issues such as structural safety hazards, functional deficiencies, and environmental pathologies. To address the challenge of missing historical administrative records, an innovative approval model of “Planning Confirmation + Fire Safety Review” was established. At the design level, an integrated strategy was employed: High Ductility Concrete (HDC) technology was used to enhance the seismic performance of aged walls; an “independent steel structure transfer layer” was developed to protect pre-stressed components; and a “darning-style” facade renewal was implemented to create a material dialogue with historical structures. Ultimately, the project achieved the efficient utilization of fiscal funds, transforming a closed campus into a shared community sports and cultural space. This project provides replicable experience—from diagnosis and approval to design and construction—for the renovation of existing campuses nationwide.
