If a building has more than 8 façades, the deployment of another weather station is rec-
ommended; particularly as this also makes it possible to measure the wind speed in
another location.
When there are several buildings, wind measurement should take place separately for
each building (e.g. with additional KNX W sl wind sensors), as, depending on the po-
sitions of the buildings in relation to one another, different wind speeds may occur.
6.17.2. Orientation and inclination of the façade
Alignment and slant of the façade are needed for the shadow edge tracking and the slat
auto-guide.
Example: If the building is skewed by
α
= 30°, then the direction for façade 1 = 30°,
façade 2 = 120°, façade 3 = 210° and façade 4 = 300°.
Fig. 20
In buildings with an asymmetrical layout
the façades with a non-right-angled orien-
tation (2, 3, 5) and façades that are set back
(6) must be controlled separately.
Curved/round fronts should be divided into
several façades (segments) to be controlled
individually.
Fig. 21
The façade orientation corresponds to the
angle between the North-South axis and
the façade vertical. The angle
α
is measured
here in a clockwise direction.
The façade orientations result as follows:
Façade 1:
Façade 2:
=
+ 90°
Façade 3:
=
+ 180°
Façade 4:
=
+ 270°
