How many degrees is it bad to deviate from the residential orientation?

From the point of view of lighting, the orientation of the house should not be due south, but due south, preferably southeast, with an angle of 15 to 25 degrees, beyond which it will not work.

Generally speaking, the higher the latitude, the more inclined it is, and 20 degrees is more suitable for most parts of China.

1, the direction of modern houses is sunny, with the most daylighting side in the house as the direction.

2. The orientation of modern residence is shape-oriented. If the building is built on a mountain, or the terrain is undulating, the lower is the orientation.

3. The orientation of modern residence is dynamic. If there is only one street in front of a building, take this street as the orientation. If the building is surrounded by streets or the building is rectangular, take the sun as the direction.
