OEM Overview:
OEM Case Study: BIPV Curtain Wall for Philippine Hospital
Cooperation Mode
OEM custom manufacturing for a commercial renovation project
Project Background
A private hospital in General Santos City, Philippines, was upgrading its old curtain wall to reduce summer cooling costs while maintaining a clean, professional medical facility appearance. The building's south-facing facade absorbed significant heat under tropical sun, driving up air conditioning expenses year-round.
Our OEM Customization
Custom BIPV glass panels: Manufactured photovoltaic glass curtain wall units with semi-transparent solar cells, allowing natural daylight into the building while generating electricity
Thermal insulation optimization: Specified low-emissivity glass with argon fill to reduce heat transfer, tailored to the tropical climate of Mindanao
Dimension customization: Cut and fabricated each panel to match the hospital's existing window grid, minimizing on-site modification and installation time
Quick-install design: Designed pre-assembled unitized panels to reduce on-site labor and keep disruption to hospital operations minimal
Packaging: Custom export packing with wooden crates to protect glass panels during ocean freight to Davao
Results
The project was installed without interrupting daily hospital operations
Initial post-installation monitoring showed approximately 12–15% reduction in monthly cooling energy consumption
The generated solar power contributes a portion of the hospital's daytime electrical needs
The client has returned to Welons for additional renovation projects at other facility locations
This OEM project demonstrates our ability to combine BIPV glass production with architectural customization, delivering a ready-to-install solution that meets both aesthetic and energy-saving goals for commercial clients.
