1. Structural Requirements

• Strength and Stability: Sports buildings, especially arenas and stadiums, require curtain wall systems that can support heavy glass panels and withstand large structural loads, including wind and seismic forces. The curtain wall must be integrated into the building’s frame to ensure it supports the overall structural integrity of the building.
• Integration with Roof Structure: In open or semi-open stadiums, curtain walls may be designed to integrate with the roof structure to provide seamless transitions between the building’s envelope and the interior space.

2. Glass Selection

• High-Performance Glazing: Glass choices are critical in a sports building. Double-glazed or triple-glazed insulated glass units (IGUs) are recommended for energy efficiency. These systems reduce heat loss or gain and improve acoustic performance.
  • Low-E Coating: This coating reduces the amount of solar heat gain and increases thermal efficiency while still allowing for high levels of natural light.
  • Reflective Glass: Reflective glass can control solar heat gain, ensuring the interior stays cool, especially in sunny climates or outdoor stadiums.
  • Toughened or Laminated Glass: For safety, curtain wall systems in sports buildings should use toughened or laminated glass, which is more resistant to impact and less likely to shatter on breakage.

3. Sustainability and Energy Efficiency

• Green Building Certification: Many sports facilities aim to meet sustainability standards such as LEED (Leadership in Energy and Environmental Design). Curtain walls can play a major role in this by incorporating sustainable materials (e.g., recycled aluminum frames) and energy-efficient glazing.
• Solar Control: Curtain walls with integrated solar control glazing can help reduce the need for artificial cooling, particularly in large stadiums or arenas that are exposed to high levels of sunlight. This is especially important in warmer climates where managing heat gain is a priority.
• Natural Ventilation: Incorporating operable windows or vents in the curtain wall design can enhance airflow and ventilation. This can help reduce the reliance on air conditioning systems and improve energy efficiency.

4. Safety and Security

• Impact-Resistant Glass: In high-traffic or high-risk areas, such as near the field or court in stadiums, curtain wall systems can incorporate impact-resistant glass to ensure safety. This is particularly important for protecting the building from flying objects (e.g., balls) or vandalism.
• Fire Safety: Fire-rated glass may be necessary in areas where the curtain wall is close to public spaces or corridors. This ensures the building’s fire safety requirements are met, preventing the spread of fire between different sections of the facility.
