Performance Mock-Up & Validation Testing
To ensure compliance with the project's stringent performance criteria, a full-scale mock-up was subjected to a comprehensive testing regime at the Intertek-ATI laboratory. The validation program included:
- Air and Water Infiltration: Rigorous testing in accordance with ASTM E283, ASTM E331, and AAMA 501.1.
- Structural & Seismic Movement: The mock-up successfully endured inter-story drift and seismic movement tests per AAMA 501.7 and AAMA 501.4.
Thermal Performance & Condensation Analysis
A comprehensive thermal analysis was conducted to verify that the façade system met the project's energy performance requirements. Using THERM 7 / WINDOW 7 software, the U-value for each system was confirmed to surpass the specified requirements.
U-value Verification Results
- WT-1A (Vision):
Achieved U-value: 0.28 Btu/h⋅ft²⋅°F (Project Specification: 0.33 Btu/h⋅ft²⋅°F)
- WT-1B (Shadow-box):
Achieved U-value: 0.20 Btu/h⋅ft²⋅°F (Project Specification: 0.21 Btu/h⋅ft²⋅°F)
- WT-2A (Vision panel):
Achieved U-value: 0.19 Btu/h⋅ft²⋅°F (Project Specification: 0.75 Btu/h⋅ft²⋅°F)
A condensation risk analysis was also performed, confirming that the design would prevent condensation under specified winter conditions, ensuring occupant comfort and long-term durability.
