Study on the Design Method of Urban Renewal Based on Carbon Emissions and Carbon Sinks Calculation: A Case Study of Environmental Improvement Project of Suzhou Industrial Investment Science and Technology Innovation Park

Under the guidance of the dual-carbon policy, low-carbon design has gradually become one of the important indicators for evaluating urban design solutions. Taking the environmental enhancement project of Suzhou Industrial Investment Science and Technology Innovation Park as an example, this paper constructs a design-oriented carbon estimation system in terms of carbon emissions and carbon sinks of buildings and landscape by calculating the quantity of architectural components and plants with the carbon factors, aiming to quantitatively assess the carbon reduction benefits of design solutions and provide timely design feedback for solution comparison and optimization. Finally, four low-carbon design strategies are summarized for urban renewal projects: rational demolition and construction, three-dimensional parking, low-carbon materials, and carbon sequestration by plants. This study incorporates low-carbon indicators into the evaluation of design schemes of urban renewal project, providing a scientific basis and practical guidance for practicing the concept of sustainable development and contributing to achieve the dual-carbon goal.
