What term describes Le Corbusier's sun-shading devices?

Le Corbusier's sun-shading devices are called brise-soleil.

The French term means “sun breaker” or “sunshade.” A brise-soleil is a fixed architectural element—such as a projecting slab, screen, grille, or louvered structure—that reduces direct solar heat and glare before sunlight reaches the building’s windows. Unlike curtains or blinds, it is normally integrated into the façade.

Le Corbusier helped make the device strongly associated with modern architecture, especially through buildings such as the Palace of Assembly in Chandigarh. His concrete screens could shade large glazed areas while also giving façades a bold geometric character. The idea was practical as well as visual: high summer sun could be blocked, while lower-angle winter light might still enter.

The distractors refer to other Le Corbusier ideas. Toit-jardin means roof garden, pilotis are supporting columns that raise a building, and Modulor is a proportional system based partly on human measurements. Brise-soleil is the single standard term for the shading feature itself.
