Are vacuum integrated photovoltaic curtain walls performance-driven?
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.
Do VPV curtain walls block solar radiation?
In contrast, VPV curtain walls with high PV coverage may block large amounts of solar radiation entering the room, increasing energy consumption for lighting and heating. Thus, the single-objective optimal design of the VPV curtain walls is unable to balance its restrictive and even contradictory functions.
Is a BIPV/T curtain wall suitable for building integration purposes?
The present study documents the design, development and testing of a BIPV/T curtain wall prototype, featuring several thermal enhancing techniques that have been deemed suitable for building integration purposes.
Are VPV curtain walls mutually constraining?
However, there is a lack of in-depth, performance-driven optimal design that considers the mutually constraining functions of the VPV curtain wall. To address this issue, this study proposed a multi-function partitioned design method for VPV curtain walls aimed at reconciling the competing demand of different functions.
Can partitioned design improve the performance of VPV curtain wall?
In summary, partitioned design method of the VPV curtain wall can improve the performance of the conventional VPV curtain wall with the same overall PV coverage. Fig. 17. Comparison of VPV windows with different PV cells distributions of coverage of 40%. 3.3.2. The optimal case obtained using TOPSIS
Can a BIPV/T curtain wall improve thermal efficiency?
A BIPV/T curtain wall prototype was studied experimentally in an indoor solar simulator facility. Thermal enhancement techniques, including multiple inlets, semi-transparent instead of opaque PV and a newly introduced flow deflector were evaluated. Test results showed a thermal efficiency of up to 33%.
