Passive Cooling Ventilated Perforated Metal Panel for Shading: Elevating Building Performance

With the intensifying focus on sustainable architecture, passive cooling ventilated perforated metal panels for shading have emerged as a transformative solution. These panels allow architects and developers to reduce energy use, improve indoor comfort, and meet green building standards without compromising design integrity.

Why Passive Cooling and Ventilation Matter

Buildings account for nearly 40% of global energy use, and much of this is driven by HVAC systems combating solar heat gain. Integrating shading systems that also support natural ventilation enables passive heat rejection, significantly lowering cooling loads. This dual-function facade solution supports net-zero goals while offering striking aesthetic benefits.

Take the example of an R&D facility in Kuala Lumpur. Facing west, the structure suffered from intense solar exposure. After retrofitting with perforated aluminum panels featuring 45% open area and integrated shading fins, indoor temperatures dropped by 3.1°C and energy usage fell by 24%. Explore project details

Technical Composition and System Benefits

Our panels are made from 3003/5052 marine-grade aluminum, offering corrosion resistance and structural strength. Available in panel thicknesses from 2mm–4mm, each unit is PVDF-coated for UV protection and self-cleaning. Perforation options include round, oblong, and slot-hole designs tailored to airflow and shading simulation outputs.

One recent facade in Qatar featured triangular-pattern perforations with customized depth to cast dynamic shadows across glass corridors. It combined passive cooling and light filtration while elevating facade identity. View Qatar application

Case Study: Tech Hub in Thailand

This LEED-targeted project used vertical ventilated panels with 40% airflow area and shading cutouts oriented to the solar path. CFD modeling during design stages ensured optimal cross-ventilation through the double-skin facade. Sensors post-installation showed:

• Up to 29% reduction in HVAC use

• Surface glass temperature drop of 7°C

• Interior glare reduced by 38%

The panels were installed on adjustable aluminum sub-frames allowing seasonal repositioning. Read full results
