A screening device (3) for screening exterior light (2) which illuminates a room (1), is controlled such that in the room on the one hand, user comfort with regard to freedom from dazzling and room temperature is optimal and, on the other hand, energy consumption for artificial lighting within the room or for heating and cooling the room is minimized.

Method and apparatus for controlling a screening device based on more

An apparatus for controlling and/or regulating process parameters of an installation such as a building automation installation has at least a first decision table and preferably a second decision table. The decision tables have rules with which a priority is associated. By evaluating the rules of the first decision table, on the basis of the state of a sub-system of the installation, a further state value is ascertained and fed to an input of the second decision table. The state of a further sub-system of the installation is altered by evaluation of rules of the second decision table. The decision tables can be represented for an installation operator in a picture screen window.
