Shading: thermo-automatic control and shading correction

Constant light control

If a minimum light strength in the room is not reached but

the room is occupied, the constant light control function switches on

automatically. Conversely, if the amount of external light increases,

the proportion of artiﬁ cial light automatically reduces or is switched

off once a suitable lighting strength is reached. If the occupancy

detector identiﬁ es that the room is empty, the constant light control

function switches itself off on a time-delay basis.

Shading

Control of solar shading is integrated directly into the

room automation system. The “thermo-automatic” function supports

the heating and cooling function of the room if it is not occupied.

To beneﬁ t from sun light in winter, solar shading is raised to help

heat the space using the sun’s rays. In summer, the solar shading is

automatically activated to reduce the energy yield from the sun and to

assist cooling.

If the room is occupied and the sun is shining in strongly, the solar

shading is automatically activated. The louvre adjustment optimises

the angle of the louvre according to the position of the sun. The

blades are positioned in such a way as to prevent blinding from direct

sunlight while keeping the need for artiﬁ cial lighting to a minimum in

order to reduce energy consumption.

The shading correction function calculates the shadow movement

on the facades of the building, depending on the position of the

sun, the facade orientation and the position and coordinates of the

surrounding buildings that provide shade. This prevents unnecessary

activation of the solar shading and increased energy consumption due

to the use of artiﬁ cial light within the building.
