Achieving high-performance façades has become a central priority for architects, engineers, and developers as buildings face stricter requirements related to energy efficiency, carbon emissions, daylight comfort, durability, and total operational cost. In response, Saint-Gobain Glass has partnered with Kvadrat Shade to introduce a dynamic façade solution that strategically combines COOL-LITE® solar control glazing with metallised internal shades for outstanding all-round performance.
At the core of this system is COOL-LITE®, a family of solar control coatings produced using advanced magnetron sputtering technology. These coatings deliver low solar factor values—typically g-values between 0.25 and 0.40—while retaining high visible light transmission. This ensures façades remain bright and comfortable without excess heat gain. Complementing the glazing, Kvadrat Shade’s metallised textiles incorporate an aluminium-backed layer that reflects solar radiation before it reaches the interior, significantly improving glare control and reducing cooling demand.
A comprehensive comparative study carried out by Saint-Gobain Glass analysed the performance of this combined system across multiple European climates, including Mediterranean, oceanic, continental, and northern regions. Using dynamic thermal simulation, climate-based daylight modelling, carbon lifecycle calculations, and cost analysis, the study evaluated energy use, daylight quality, visual comfort, and environmental impact.
Key Performance Results
- 20–30% reduction in cooling energy demand compared with standard double glazing and traditional textile blinds
- Higher daylight autonomy, reducing the need for artificial lighting during daytime hours
- Lower glare probability (DGP) values across seasons, ensuring consistent visual comfort
- Reduced façade carbon footprint, supported by lower operational energy use and recyclable materials
- Optimised total cost of ownership, with minimal maintenance and competitive installation costs
These findings confirm that pairing COOL-LITE® glazing with metallised shading creates a façade solution that achieves a rare balance between comfort, sustainability, and technical performance. The system maintains outward views, enhances thermal stability, and supports carbon-conscious design strategies, making it ideal for offices, education buildings, cultural projects, and high-performance renovations.
