An increase of knowledge of the mid- term performance of building integrated bifacial photovoltaic modules in real conditions is required in order to validate their relevance. Thus, in this work, the experimental study during more than one year of an innovative building integrated bifacial photovoltaic ventilated façade developed in the framework of the CONIPHER Life project and mounted on a test cell at Le Bourget du Lac is presented focusing mainly on the photovoltaic modules thermal behaviour and electrical performance. Moreover, a specific attention is made on the photovoltaic façade seasonal impact on the building energy consumption compared to a similar test cell comprising a non-insulated concrete wall. An important thermal gradient is observed along the façade in warm season, as expected, mainly due to site albedo, with mean photovoltaic modules temperature up to 68.3 °C. The innovative facade produced an annual cumulated electrical energy of 63.8 kWh/m² with a performance ratio of 0.7 and a mean annual efficiency of 6.3%. A huge reduction of the building total energy consumption up to 92% in winter compared to reference is observed. As further studies, the facade will be installed on an office building in order to demonstrate its performance in real conditions.

为了验证其相关性，需要更多地了解建筑集成双面光伏组件在实际条件下的中期性能。因此，在这项工作中，对在 CONIPHER Life 项目框架内开发并安装在 Le Bourget du Lac 的测试电池上的创新建筑集成双面光伏通风立面进行了一年多的实验研究，主要关注光伏模块的热行为和电气性能。此外，与包含非绝缘混凝土墙的类似测试电池相比，光伏外墙对建筑能耗的季节性影响受到了特别关注。正如预期的那样，在暖季沿立面观察到一个重要的热梯度，主要是由于场地反照率，平均光伏组件温度高达 68.3 °C。创新的立面产生的年累计电能为 63.8 kWh/m²，性能比为0.7，平均年效率为6.3%。与参考相比，冬季建筑总能耗大幅降低了 92%。作为进一步的研究，立面将安装在办公楼上，以展示其在真实条件下的性能。
