It is based on the wind characteristics at the different façade areas and on the wind characteristic of the wind anemometer on the roof. Both informations are put together in a computer algorithm which enables an individual controlling of each façade area [1, 2, 3, 4, 5]. The wind action at a building façade is different at the different sides of the building and depends on the wind direction. With the “wind characteristic technique” an economic control of the sun protecting system is possible, i.e. the sun protecting effect can be optimized at each part of the façade and the screens are protected reliably. INTRODUCTION Sun screens at the outer surface of a façade are endangered by wind action. Therefore the screens must be pulled up at critical wind speed. This procedure requires a control system. The classical control system requires an installation of several anemometers at many positions at the façade. Another control system is to use one central anemometer on the roof of the building. The first system has the disadvantage to install many anemometers, which is expensive and disturbs the image of the façade and the second system pulls up all screens at critical wind speed, also at façades where the wind action is low. For an optimal sun protection and optimal safe protection of the elements an intelligent control sys-tem is required. This control system must include three aerodynamic informations:
