Wall-mounted Sunshade and Ventilation Perforated Metal Cladding for Retrofit Projects

As urban environments evolve, retrofitting aging buildings becomes a strategic necessity. Wall-mounted sunshade and ventilation perforated metal cladding systems provide a transformative solution—improving energy performance, thermal comfort, and facade aesthetics in one integrated upgrade.

Why Retrofit with Ventilated Cladding and Sunshades?

Retrofit projects often face the triple challenge of high cooling loads, solar glare, and dated appearance. Integrating wall-mounted sunshade systems with ventilated cladding addresses all three:

• Sunshades reduce direct solar gain, easing HVAC demand

• Ventilation cladding allows passive airflow, reducing interior temperature

• Modern finishes restore visual appeal to outdated facades

According to ArchDaily, ventilated facades also enhance building envelope protection, extending facade life. We’ve applied these methods in prior retrofit projects across schools and commercial towers.

Case Study: Mid-rise Commercial Building in Manila

This five-story 1990s building suffered from overheating and dated aesthetics. The client installed aluminum wall-mounted sunshades and perforated galvanized cladding spaced 70mm from the wall. Using custom angled brackets, the project was completed in four weeks with minimal disruption.

• Interior temperatures dropped 10.6°C in west-facing offices

• Tenant complaints reduced by 64%

• Annual HVAC savings estimated at 19.8%

• Improved facade branding supported rental increase

Validated by results, this retrofit was later featured in a sustainability journal as a model for tropical facade redesign. Read more on our approach in similar applications.

System Components and Performance Details

The aluminum alloy sunshades were powder-coated for corrosion resistance, positioned for maximum solar cut-off between 1PM–5PM. The cladding was perforated 40% open with staggered round patterns to balance shade and airflow.

Key design insights were informed by WBDG façade guidelines and thermal mapping tools from ScienceDirect.

Addressing Pain Points for Retrofit Clients

Clients often face:

• High energy bills from legacy curtain walls

• Low occupant satisfaction due to thermal inconsistency

• Loss of leasing competitiveness from poor exterior image

Our integrated cladding-sunshade approach resolves these pain points, as proven in multi-use projects and facility upgrades.
