Can we use the prescriptive method if there is a fixed exterior brise soleil in the façade?
Can we use the 63 angle from the brise soleil to exclude part of the daylight area?

If the brise soleil runs the entire height of the window, no. The prescriptive method, in its simplicity, is based on the windows access to the sky vault. That is why the 63 degree angle comes into play when determine the daylight zone depth. With a secondary façade, even like the breis soleil, the prescriptive method cannot consider this.
