Controlling sunlight has long been a concern in architecture, particularly in warmer climates where glare and overheating affect comfort and energy use. One solution that continues to gain attention is Brise Soleil, a design feature that balances light control with visual interest and supports environmental goals.
What Is Brise Soleil and Where Did It Come From?
Brise Soleil refers to external solar shading elements positioned on a building façade or over windows to reduce direct sunlight. Early examples include lattice screens, pierced stone panels and bamboo blinds used across Asia, the Middle East and southern Europe. The modern concept developed in the twentieth century, most notably through Le Corbusier, who introduced adjustable shading systems for large office buildings in hot climates.
How Brise Soleil Works in Practice
The primary role of Brise Soleil is to limit solar gain while still allowing daylight into internal spaces. Fixed or adjustable blades are designed around sun angles, building orientation and seasonal variation. Horizontal systems often suit south facing elevations, while vertical fins are effective on east or west façades.

Design and Performance Considerations
Modern systems are produced using materials such as aluminium and steel, offering durability and flexibility. They can be integrated into new builds or refurbishments, supporting energy efficiency targets and façade design.
Why Brise Soleil Still Matters
Beyond thermal control, Brise Soleil adds depth and pattern to façades. For designers and planners, it remains a practical response to managing sunlight within sustainable architecture.
