Technical Feasibility and Sustainable Value of Modular Curved Surfaces in Guangzhou Urban Building Renewal: A Case Study of Yulong Garment City

Abstract

This paper focuses on the technical feasibility and sustainable design of curved surface modules in the transformation and renewal of urban construction in Guangzhou. Using a research approach that combines design practice, parametric digital modelling and case analysis, it explores the integration of curved architectural forms with modular systems.  The findings indicate that prefabricated curvature can improve construction process, enhance adaptability in high-density environments. The prefabricated curvature can reduce construction waste, improve energy efficiency, recyclability and overall life-cycle of sustainability of buildings, supporting green buildings and circular economy. The paper proposes an operable system that combines geometric rationalization design method, modular construction logic method, and systematized maintenance methods for façade system retrofitting. The practice of Yulong Garment City in Guangzhou is verified, the technical and design effect of the proposed system is verified, and the case is replicable in similar redevelopment projects. The research indicates that the modular curved surface can serve the dual purposes of aesthetics and performance in urban transformation, providing a scalable and adaptable strategy to solve the architectural and environmental issues facing modern cities. This approach is particularly suitable for urban building renewal, and can be selectively applied in projects with different budgets and technical capacities, while being more appropriate for renovation than for new public buildings.
