建筑全生命周期碳–成本动态耦合理论研究

Research on the Dynamic Coupling Theory of Carbon-Cost in the Whole Life Cycle of Buildings

摘要: 针对当前建筑领域“碳核算与成本控制割裂”“静态管控无法适配全周期需求”的核心痛点，本文提出“建筑全生命周期碳–成本动态耦合理论”。基于全生命周期评价(LCA)、碳成本传导理论与低碳计算技术，构建“时间–空间”两维耦合框架，引入动态耦合系数(Kt/Ks/Kp/Km)与双驱动调节机制，实现碳流与成本流的实时协同优化。本研究为工程造价从“单一经济成本导向”转向“碳–成本双维度管控”提供理论范式与实践路径，助力建筑行业“双碳”目标落地。

Abstract: To address the core challenges in the current construction sector, namely “the disconnection between carbon accounting and cost control” and “the inadequacy of static management in meeting whole-life-cycle requirements”, this study proposes the “Dynamic Coupling Theory of Carbon-Cost for the Whole Life Cycle of Buildings”. Drawing on Life Cycle Assessment (LCA), the Carbon Cost Transmission Theory and low-carbon calculation technologies, a two-dimensional “time-space” coupling framework is established. By introducing Dynamic Coupling Coefficients (Kt/Ks/Kp/Km) and a dual-driver regulation mechanism, the real-time collaborative optimization of carbon flows and cost flows is achieved. This research offers a theoretical paradigm and practical pathway for shifting engineering cost management from a “single economic cost orientation” to “dual-dimensional carbon-cost management”, thereby supporting the construction industry in fulfilling the “dual carbon” goals.
