Buildings, especially mid- and high-rise ones, offer the opportunity to incorporate Photovoltaics (PV) on their vertical surfaces in addition to their roofs. This is achieved through Building Integrated Photovoltaic (BIPV) solutions. Ventilated facades in buildings can facilitate PV integration and improve the envelope's thermal performance. However, research on BIPV ventilated façades is lacking in the Gulf and MENA regions. Considering the area's harsh climate, investigating these facades is critical. Therefore, the authors of this paper conducted comparative experimental research on the energy performance of BIPV ventilated facades in the hot climate of Dubai. For a year, they monitored the energy yield and temperatures of Copper Indium Gallium Selenide (CIGS) and monocrystalline silicon (c-Si) modules on the south, east, and west facades. In addition, the study analyzed the effect of the modules' characteristics, orientation, temperature, and solar angle on the energy yield. Despite the hot temperatures, the monthly area-normalized energy yields of the c-Si modules were consistently higher than the CIGS modules across all orientations, with an average difference of 13.6%. The modules in the south facade produced the highest annual yield. Also, from October to February (the coolest period), the energy yield of the south modules surpassed the east and west modules by 41.6% and 48.5%, respectively. However, from April to August (the highest energy demand period), the east and west energy yield exceeded the south by 40.9% and 32.5%, respectively. In addition, the west-facing modules experienced higher temperatures than those in the east, resulting in an average of 12% lower energy yields. Hence, the east façade has performed the second best. The west façade production, nevertheless, closely coincides with Dubai's peak periods curve. Thus, the combination of modules on the west and south facades achieved the strongest generation-consumption correlation.

建筑物，尤其是中高层建筑，除了屋顶外，还提供了将光伏 (PV) 纳入其垂直表面的机会。这是通过建筑集成光伏 (BIPV) 解决方案实现的。建筑物的通风外墙可以促进光伏集成并提高围护结构的热性能。然而，海湾和中东和北非地区缺乏对 BIPV 通风外墙的研究。考虑到该地区恶劣的气候，调查这些外墙至关重要。因此，本文作者对迪拜炎热气候下BIPV通风外墙的能源性能进行了对比实验研究。一年来，他们监测了南、东、和西立面。此外，该研究还分析了组件的特性、方向、温度和太阳角度对发电量的影响。尽管温度很高，但 c-Si 模块的月面积归一化能量产量在所有方向上始终高于 CIGS 模块，平均差异为 13.6%。南立面的模块产生了最高的年产量。此外，从 10 月到 2 月（最冷期），南部组件的发电量分别超过东部和西部组件 41.6% 和 48.5%。然而，从4月到8月（能源需求最高时期），东部和西部的能源产量分别超过南部40.9%和32.5%。此外，面向西的模块经历了比东部更高的温度，导致能源产量平均降低 12%。因此，东立面表现第二好。然而，西立面的生产与迪拜的高峰期曲线非常吻合。因此，西、南立面的模块组合实现了最强的发电-消费相关性。
