  • Small Annex Structure with Side-Mounted Metal Sunshade and Vent Slots: A Practical Approach to Energy-Efficient Envelope Design

    Product Description (Product Attributes)

    Material: 6063-T6 aluminum alloy, 2.0 mm thick
    Finish: Anodized surface, RAL 9006, PVDF UV-resistant coating (ASTM G154 compliant)
    Vent Geometry: Horizontal slots, 15 mm × 100 mm, 12% open area, with internal one-way baffles
    Panel Dimensions: Custom, fitted to 3 m × 5 m × 2.7 m annex walls
    Airflow Channel Depth: CFD-tested, pressure drop < 20 Pa at 4 m/s wind
    Thermal Performance: Solar transmittance reduced by 36%, ISO 15099 validated
    Wind Load Resistance: Designed to ASCE 7-22 wind standards
    Mounting: Modular system with ASTM A325 standard connection bolts
    Cooling Effectiveness: Wall temperature reduced from 57–59 °C to 42–44 °C
    Energy Efficiency: HVAC duty cycle reduced by 23%
    Moisture Management: Built-in drainage channels to control condensation
    Noise Control: Acoustic performance validated (ISO 11654 Class A foam optional)
    Retrofit Time: 1 day per façade, no downtime required
    Application: Control rooms, substations, on-site server or monitoring cabins
    Durability: ASTM E330 (structural), ISO 6946/15099 (thermal), ASCE 7-22 (wind), ASTM G154 (UV) compliant
    Maintenance Cycle: Reduced by 25% after installation
