This green curtain wall uses photovoltaic glass as the curtain wall surface. By utilizing the characteristics of photovoltaic technology with high power generation during sunshine hours, it can reduce dependence on external electricity, provide electricity for the public area lighting in the subway, and take into account the small power loads such as entrance escalators and elevators. At the same time, ground buildings such as subway entrances and exits, elevators and elevator halls are mainly used for personnel transportation, and the lighting demand is relatively small. The traditional glass curtain wall is the outer protective structure of the subway entrance and exit and other ground buildings. The heat gain surface is large and the energy consumption is high. This green curtain wall uses photovoltaic glass with a certain light transmittance to effectively reduce the solar radiation heat in hot areas from entering the room, and significantly reduce the energy consumption of building air conditioning;

[0011] It can effectively save materials. This green curtain wall system uses photovoltaic glass as the surface material of the outer curtain wall system of subway entrances and exits, elevators and elevator lobbies, replacing traditional materials such as stone and glass, and realizing the organic integration of solar energy utilization and building envelope structure. At the same time, compared with the secondary structure system of traditional photovoltaic systems, this curtain wall realizes building photovoltaic integration, which not only saves material costs, but also takes into account the overall appearance and effect of the building facade. In addition, this curtain wall can be applied to various locations such as subway entrances and exits, elevators and elevator lobbies, and has a wide range of application and promotion prospects.
