SLAT TRACKING
The “slat tracking” function ensures that the sunblind slats automatically adjust to the position of the sun. In this way, the diffuse
daylight that shines through the blinds can be used. At the same time, the proportion of artificial light can be reduced, the “slat
tracking” function makes lighting energy savings of 10 to 13 percent possible.
INTERACTION BETWEEN SLAT TRACKING AND CONSTANT LIGHT CONTROL
An integrated system permits functions such as slat tracking and constant light control to be used together and in coordination. This
combination is especially advisable in rooms with a good supply of daylight. The savings here can be up to 30 percent.
INTEGRATED ROOMAUTOMATION SYSTEM
A precondition for the optimal effectiveness of all functions is an integrated room automation system, in which the different
systems such as heating, cooling or glare shield work in unison. In an integrated room automation system, the sensors provide the
information for all the systems, while actuators and the lighting, heating, and cooling systems, provide simultaneous support.
PLANNING AND CONFIGURATIONOF AN ENERGY SAVING ROOMAUTOMATION SYSTEM
The planning and configuration of an energy saving room automation system is simplified by the fact that the room automation
system functions conform to the Lonmark profiles used around the world. With this system, room automation functions can be
described clearly and comprehensively.
Once the desired room automation functions have been selected, the savings potential of the particular room automation solution
can be determined, and the chosen solution can be configured with devices.
