Requirements Analysis

The system designer is supported in the task of requirements analysis by a knowledge-based requirement tool (depicted in figure 1). This tool allows an easy definition of room types and the specification of required room control functions, which are presented on the right side sorted by the different trades. Context-aware assistance is also provided by automatically selecting additional required functions, such as brightness measurement, presence detection and a dimmable light actuator are necessary to realize a constant-light control. Additional features may also be chosen by the user – in case of the constant-light control, several light switches with dimming functionality or scene selection switches would be appropriate.
