PHOTOVOLTAIC CURTAIN WALL CONSTRUCTION FOR
Building-integrated photovoltaics (BIPV) are evolving beyond simple solar panels, with transparent solar cells and solar skin technologies that can be seamlessly incorporated into windows,
The vacuum integrated photovoltaic (VPV) curtain wall has garnered widespread attention from scholars owing to its remarkable thermal insulation performance and power generation ability. However, there is a lack of in-depth, performance-driven optimal design that considers the mutually constraining functions of the VPV curtain wall.
According to the literature review, VPV curtain walls exhibit significant potential for energy savings owing to their excellent thermal insulation performance . Furthermore, the shading effect of PV cells can alleviate discomfort glare and enhance occupants' visual comfort .
When aiming at the highest RNEH (ω 1 = ω 2 = ω 3 = 0.01, ω 4 = 0.97), the partitioned VPV curtain wall with 20%, 40%, and 90% PV coverages of the daylight, view, and spandrel sections achieved the highest RNEH of 64.7%. However, the corresponding glare index is as high as 29.4%.
