夏热冬冷地区某办公楼低碳改造模拟研究

Simulation Study on Low-Carbon Renovation of an Office Building in a Region with Hot Summers and Cold Winters

摘要: 以夏热冬冷地区典型城市武汉的一栋中小型办公建筑为对象，基于“被动式技术优先、主动式技术优化、可再生能源补充”的递进式改造策略，系统分析了不同技术路径对建筑运行阶段能耗与碳排放的影响。利用EnergyPlus软件模拟了围护结构改造、地源热泵空调系统应用所对应的降碳率，以及可再生能源技术的碳排放替代率。

Abstract: Focusing on a medium-sized office building in Wuhan—a typical city in regions with hot summers and cold winters—the study systematically analyzed the impact of various technical approaches on energy consumption and carbon emissions during the building’s operational phase, employing a progressive renovation strategy that prioritizes passive technologies, optimizes active technologies, and supplements them with renewable energy. Using EnergyPlus software, the study simulated the corresponding carbon reduction rates from envelope renovations and ground-source heat pump air conditioning systems, as well as the carbon emission substitution rates achieved through renewable energy technologies.
