摘　　要：光伏建筑一体化(BIPV)组件能够结合建筑外遮阳与光伏发电组件,是实现建筑近零能耗目标的有效手段,近年来受到学界的广泛关注。BIPV遮阳百叶系统通过在建筑立面附加外置BIPV水平遮阳百叶的方式,减少室内直射太阳辐射,利用太阳能补贴建筑能耗,从而减少建筑能耗,增加可再生能源利用率,改善室内光环境。以广州市典型办公房间为对象,对BIPV遮阳百叶系统的关键参数进行敏感性分析,得到不同参数对典型房间净能耗的影响程度。此外,以房间净能耗最小为目标,对BIPV遮阳百叶系统的关键参数进行全局寻优,得到各朝向下的最优参数工况。对各朝向最优BIPV遮阳百叶系统工况的房间能耗、光环境与经济性进行分析。Building-integrated photovoltaic(BIPV) module, as an effective way to achieve the nearly zero energy building goal, can combine exterior shading components with photovoltaic panels, has attracted the attention of the academic community in recent years. The BIPV shading louver system was studied. The system adds external BIPV horizontal shading louvers to the building facade to reduce indoor direct solar radiation, and use solar energy to subsidize building energy consumption, thereby reducing building energy consumption, increasing the utilization rate of available energy, and improving indoor light environment. Based on the typical office room in Guangzhou, the sensitivity analysis of the parameters of the BIPV shading shutter system was carried out. Therefore, we got the degree of influence of different parameters on the net energy consumption of the typical room. In addition, with the goal of minimizing the net energy consumption of the room, the optimization of the BIPV shading louver system is carried out. As a result, we got the optimal BIPV parameter combination for each orientation. The room energy consumption, light environment and economy of the optimal BIPV shading shutter system for each orientation are evaluated.
