Architects use brise-soleil as solutions to overheating in many hot climates with long days of direct sunlight. These permanent sun-shading structures range from simple patterns of concrete fins to more elaborate wing-like mechanisms that can be adjusted based on different solar angles throughout the day and across the seasons. Some buildings incorporate louvers into the shades to mitigate high-angle rays in summer, but also permit low-angle winter sunlight for passive solar heating with a variety of pattern structures that act as light-filtration screens on the façades of buildings.

One of the most common types of brise-soleil, simple concrete fins, became widespread after Le Corbusier’s Ministry of Education and Health was completed in Brazil.
