Sun position
Set the
direction and height of the sun for shading. The angle, which is specified for
the direction of the sun (azimuth), is aligned according to the orientation of the façade.
In addition, the angle of the façade and obstacles which cast a shadow on the façade,
such as, for example, a wall or overhanging roof, can also be taken into account in the
setting for sun direction (azimuth) and sun height (elevation).

1b: Sun elevation (Azimuth)
For façade 1, shading must only be active
in the azimuth marked red, as the sun can
then shine on to the building without ob-
struction

2: Sun position (Elevation)
When the sun's position is high, the façade
is only shaded by the roof overhang. Shad-
ing is only necessary if the sun is low (in the
figure approx. below 53°).
