Case Study: Metal Sunshade & Simple Slot Ventilation Panels for Outdated Facade Upgrades 

Abstract:  This case study details the renovation of outdated building facades using modular metal sunshade and simple slot ventilation panels. The client’s building suffered from excessive heat gain, poor ventilation, and an aging appearance that affected energy efficiency and corporate branding. By installing custom sunshade panels and slot ventilation systems, the building experienced improved thermal comfort, enhanced airflow, and a modernized exterior. This article covers project background, design strategy, fabrication, installation, performance results, and key lessons, with references to both internal and external authoritative sources.

1. Project Background: Outdated Facade Challenges

The building, constructed in the 1980s, had flat steel panels and outdated louvers. The client faced the following issues:

• Excessive internal heat during peak sunlight hours.

• Insufficient natural airflow leading to high HVAC consumption.

• Degraded aesthetic appearance affecting brand perception.

• Difficulty in retrofitting traditional sunshades without structural modifications. (Internal Panel Guide)

Jintong Perforated Metal proposed modular metal sunshade panels and simple slot ventilation panels that could be retrofitted with minimal disruption. (Internal Installation Guide)

2. Why Metal Sunshade & Slot Ventilation Panels Work

Metal sunshades block direct sunlight, reducing heat gain, while slot ventilation panels enable passive airflow. According to Kawneer, sunshades improve energy efficiency and occupant comfort. (Kawneer Article)

Slot ventilation panels allow airflow without mechanical fans. Wiremeshfabs notes that “slot panels promote natural ventilation and reduce maintenance.” (Wiremeshfabs Study)

Studies confirm that sunshade and slot ventilation systems can reduce heat gain by 15–30%. (MDPI Study) Passive ventilation can reduce HVAC reliance by 35–50%. (Transit Tomorrow Study)

3. Design & Specification

• Material: Aluminium 6061-T6 (4 mm) for sunshade, stainless steel 316 (3 mm) for slot ventilation panels.

• Sunshade: Horizontal projection of 400 mm, powder-coated for UV and weather resistance. (Internal Panel Design Guide)

• Slot ventilation panels: 100 mm slot openings along side and top elevations to enable airflow. (Prance Building Study)

• Mounting: 60 mm ventilated gap behind panels for passive airflow. (TBK Metal Article)

• Installation: Modular clip-on panels allowing retrofit without major structural changes. (Archro Installation Guide)

4. Fabrication & Installation

QA included thickness verification, perforation accuracy, and powder-coat adhesion tests. Kits were shipped to site and installed by four technicians over a weekend. Steps: attach sub-frame, clip-in sunshade panels, install slot ventilation panels, seal base joints. (QS-Wiremesh Case Study)

5. Performance Outcomes

• Facade surface temperature decreased by 12–15 °C during peak sunlight.

• Natural airflow improved, reducing HVAC load by 30 %.

• Maintenance visits reduced due to lower dust ingress.

• Corporate branding enhanced with modernized exterior. (ResearchGate Study)

6. Lessons Learned

• Sunshade sizing must match solar angles for optimal shading. (SHARCHS Guide)

• Slot pattern must balance airflow and dust protection. (Prance Building)

• Ventilated cavity behind panels is critical for passive cooling. (TBK Metal)

• Modular clip-on panels simplify retrofitting. (BNP Media Study)
