An experimental study on the performance of new glass curtain
It can also convert excess solar energy into electrical energy, reduce the indoor thermal load, and generate heat, which can be used to improve efficiency and reduce energy
In this context, transparent building envelopes, such as Glass Curtain Wall (GCW), have become prominent features in large public buildings [4, 5, 6]. While glass curtain walls offer significant architectural and visual appeal, they are often criticized for their low energy performance, especially in terms of thermal insulation.
Transparent curtain wall systems, introduced in the nineteenth century, have significantly influenced architectural identity and technological advancement. However, even the most efficient systems fail to meet the 2022 UN Environment Program's goal of a 95% energy consumption reduction.
Moreover, the efficiency of solar energy utilization ranged between 44% and 63%. To address the trade-off between indoor lighting and photovoltaic performance in BIPV/T (building-integrated photovoltaic/thermal) systems, a novel glass curtain wall design based on a micro-scale transmissive concentrator has been proposed [40, 41, 42, 43].
At the same time, glass curtain walls are a popular design in modern high-rise buildings, because they are not only beautiful but also use natural lighting to reduce lighting energy consumption.
