Positive and negative pressure qA=0.09 m³/(h·m²), achieving airtightness level 3.
Exceeds national building curtain wall standards requiring qA<2.0 m³/(h·m²) for general regions, and qA<1.2 m³/(h·m²) for certain special regions or floors.

Waterproofing is achieved through an outer metal cover and a horizontal/vertical drainage network between components, forming a multi-layered waterproof structure.
The architectural waterproofing principle prioritizes waterproofing with drainage as a secondary function, achieving 98% drainage + 2% drainage to realize 100% waterproofing.
Successfully passed the rain test at 30.3L/min, demonstrating zero leakage under extreme conditions.

The static load capacity of FRP BIPV roofing reaches 0.69 kN/m²; that of ZAMB BIPV roofing reaches 0.781 kN/m². Both exceed the 0.5 kN/m² standard requirement for non-trafficable roofs.
Wind uplift resistance reaches 1.4 kPa. In severe typhoon regions, the basic wind pressure (0.5 kN/m²) wind uplift resistance coefficient K_j = w_u / w_s ≥ 2. This exceeds the standard requirements for severe typhoon regions.

Central Support Structure
|
Provide robust support for photovoltaic modules
Conceal photovoltaic cables, enhance fire resistance, and achieve aesthetically pleasing construction results
|
Most solutions lack the necessary structural configuration.
|
|
|
Fully modular installation ensures higher efficiency and reliable quality.
Offers superior cost advantages and higher value for money compared to similar products.
|
Typically involves multiple installation steps such as drilling and bolting, which slows down progress.

|
Insulation layer can be installed
Fiberglass horizontal and vertical water channels can significantly reduce thermal conductivity.
|
|
|
|
All mounting hardware and photovoltaic cables feature a concealed design, enhancing the building's overall aesthetic simplicity and adhering to modern architectural principles.
|
The design of the water channel is monotonous and simplistic, making it difficult to meet the architectural aesthetic requirements of BIPV roofs.
