The sun is a source of light and heat. In the winter, heating by the sun contributes to a lower energy bill. That's nice. In the summer it quickly gets too hot without air conditioning or fans. That is less pleasant. With a brise soleil you get influence on this warming up. Especially in the summer when the sun is high, the brise soleil reflects direct solar radiation. A brise soleil is not placed in front of a window or a door, but hangs above the window or the door. So daylight is not blocked. Which contributes to a pleasant living and working environment.
