1. Water infiltration: Water infiltration or leakage is one of the most common issues in facade systems. It can lead to damage to the internal structure and also result in mold growth, which can pose health hazards.
2. Thermal performance: Facade systems must be designed to provide good thermal insulation to meet energy efficiency requirements. Poor thermal performance can lead to excessive energy consumption and high utility bills.
3. Structural stability: The facade system must be stable enough to withstand the wind, earthquakes, and other environmental loads. Any failure in the structure could lead to costly repairs or even endanger the occupants.
4. Maintenance: Facade systems require regular cleaning, inspection, and maintenance to ensure their longevity. Neglecting regular maintenance can lead to the deterioration of the system.
5. Aesthetics: The facade of an office building plays a critical role in its appearance and branding. Any damage or deterioration could negatively impact the building's image.
6. Noise transmission: The facade system must also provide good sound insulation performance. Without proper insulation, noises from outside can impair the productivity of the occupants.
7. Fire resistance: Facade systems should provide adequate fire resistance to ensure the safety of the occupants of the building. Any failure in the fire resistance can put people's lives in danger.
