摘　　要：我国建筑领域能源消耗巨大,建筑节能任务艰巨。随着“双碳”目标的提出,绿色节能成为建筑领域重要的发展方向。伴随光伏技术的日益成熟,以遮阳板、百叶等建筑构件为例的建筑表皮设计对于建筑节能减排及可再生能源利用存在显著影响。为探讨绿色节能的建筑表皮系统设计策略,借鉴了夏热冬冷地区浙江大学建筑设计研究院紫金院区B1楼的建筑表皮,选取建筑表皮单元尺寸、单元孔隙率、单元旋转角度为优化参数,利用遗传算法研究和探讨了建筑表皮与典型办公楼建筑本体能耗、光伏发电量、建筑净能耗的影响关系及优化设计方法。研究结果表明:表皮单元孔隙率与旋转角度的增长将显著降低建筑本体能耗与光伏发电量;在以不提高建筑本体能耗的情况下,追求建筑净能耗的最优化为目标,对建筑表皮进行优化后,各朝向建筑表皮可得2.19~3.16 kW·h/(m^(2)·a)的建筑净能耗节能量。The energy consumption within China’s building sector is substantial,presenting a formidable challenge in the realm of building energy conservation.With the introduction of the dual carbon goals,prioritizing green energy saving has emerged as a pivotal developmental direction in the construction field.Concurrently,as photovoltaic technology matures,the design of building skin system such as sun shades and louvers significantly influences energy conservation,emission reduction and renewable energy utilization.To investigate the design strategy for a green and energy-efficient building skin system,this study leveraged the building skin of the B1 structure within the Zijin District,Architectural Design and Research Institute of Zhejiang University,situated in hot summer and cold winter region(Hangzhou),as a reference point.Key optimization parameters included building skin unit dimention,unit porosity,and unit rotational angle.Employing genetic algorithms,this research investigated the interplay between building skin characteristics and typical office building body energy consumption,photovoltaic power generation,building net energy consumption,and optimal design methodologies.Findings indicate that increasing the porosity and rotational angle significantly diminishes building body energy consumption and photovoltaic power generation.In pursuit of optimizing building net energy consumption without augmenting building body energy usage,post-optimization of the building skin yields a range of 2.19 to 3.16 kW·h/(m^(2)·a)in building net energy consumption.
