Brise soleil means’ sun breaker ‘ and is French. To avoid overheating and glare, the blades or slats extend out from the house usually horizontally. They are also available in a vertical style and either device allows the building to have low-level light, such as morning and night, but blocks the late morning and afternoon direct sun.
Modern buildings, such as those designed for offices or schools, have large glass areas to provide as much natural daylight as possible. This achieves full light and generates an accessible atmosphere that is more spacious. The concept is to have a comfortable atmosphere based on the well-being of its inhabitants.

The issue emerging from this style of architecture is how the interior temperature of these mostly glazed buildings can be regulated. At certain times of the day, solar heat obtained from the glazing is mostly beneficial particularly during autumn and winter.
Too much solar benefit, however, can cause problems with overheating during the warmest time of day, similar to trying to function in a greenhouse. The amount of solar gain experienced, with some floors experiencing the sun more than others, is also influenced by elevation.
Installing Brise soleil is a useful way to monitor or decrease solar gain for greater comfort. As they diffuse light, these structures are aesthetically appealing, as well as practical. Temperatures are more easily managed when paired with internal blinds for solar shading.
