1. Structural Integrity

• Wind Load: Curtain walls must be designed to handle high wind loads, particularly in areas prone to storms or high winds. The framing system must be robust enough to support the glass panels while maintaining flexibility to accommodate structural movement.
• Load-Bearing Frames: While curtain walls are non-structural, they are supported by a structural framework (typically aluminum, steel, or reinforced concrete). The strength and design of the frame must ensure the curtain wall system can support the weight of the glass and withstand external pressures.

2. Glass Selection

• Thermal Performance: Low-emissivity (Low-E) coatings can be applied to glass surfaces to reflect heat back into the building during colder months and block heat from the sun during warmer months.
• Solar Control: Tinted or reflective glass can reduce solar heat gain, making it easier to maintain a comfortable indoor temperature and improve the energy efficiency of the mall.
• Safety and Security: Laminated or tempered glass should be used for safety reasons. Glass panels in high-traffic areas may also be designed with security features, such as bulletproof or impact-resistant glass, depending on the mall’s location and risk factors.

3. Integration with Other Building Systems

• Ventilation: Curtain walls can include operable windows or vents to allow for natural ventilation, which can improve indoor air quality and comfort for mall visitors.
• Lighting and Signage: Malls can integrate lighting into curtain wall systems, using backlighting or LED systems to create an attractive, dynamic nighttime aesthetic. Additionally, exterior signage or branding can be integrated into the curtain wall design.

4. Sustainability Features

• Green Building Materials: Choosing sustainable materials, such as recycled aluminum for frames or high-performance glass with reduced environmental impact, can enhance the sustainability credentials of the shopping mall.
• Rainwater Management: Curtain walls can be designed to help channel rainwater away from the building to reduce the risk of water damage and improve the building’s environmental performance.
