Abstract：Under the strategic goal of “carbon peak and carbon neutrality”, how to realize low-carbon and sustainable development
of urban built-up areas through urban renewal has become a key issue of new urbanization. This paper analyzes the
“high carbon effect” of the traditional renewal mode, combines the urban renewal practice in Hefei City with the three
dimensions of spatial reconfiguration, technological upgrading, and governance innovation to propose a high-quality
development path for urban renewal, and builds the three major low-carbon renewal strategies of ecological carbon
sinks, low-carbon transportation, and green buildings by taking the example of the left bank of the Sili River in Luyang
District, Hefei City. Through blue-green spatial stitching, block scale optimization, and carbon reduction in the whole
life cycle of buildings, urban renewal can be transformed from “scale expansion” to “connotation efficiency”, providing
a practical design strategy paradigm for urban renewal in high-density built-up areas.
