| 随着双碳目标的推进,建筑节能需求日益凸显,在建筑设计阶段高效达成国标要求并降低总体能耗愈发关键。本研究以夏热冬冷地区高层住宅建筑为对象,借助 Rhino 软件与 Grasshopper 插件构建基准能耗模型,运用局部因素敏感性分析法,选取弧均值弹性为指标,剖析围护结构参数、朝向及水平外遮阳对建筑能耗的影响规律。结果表明,各因素对建筑总能耗影响的平均敏感性排序前四的为：外墙传热系数 > 外窗传热系数 > 外窗太阳得热系数 > 建筑朝向。因此,建筑设计因素节能优化重点在于外墙传热系数、外窗传热系数、外窗太阳得热系数,以及设置移动式外遮阳和内遮阳。 |

| In alignment with the dual carbon targets, the significance of energy efficiency in building design is increasingly recognized. Achieving national standards and minimizing energy consumption during the architectural design phase is of paramount importance. This research investigates high-rise residential buildings in regions characterized by hot summers and cold winters. Employing Rhino software and the Grasshopper plugin, a benchmark energy consumption model was established. Sensitivity analysis of local factors, using arc mean elasticity as a metric, was conducted to assess the impact of building envelope parameters, orientation, and horizontal external shading on energy consumption. The analysis reveals that the primary factors influencing total building energy consumption, ranked by their average sensitivity, are as follows: the external wall heat transfer coefficient, the external window heat transfer coefficient, the external window solar heat gain coefficient, and the building orientation.Therefore, th |
