A Sample Case of an Advanced Lighting System in an Educational Building

The paper describes a case history of an advanced lighting control system designed and realized for a couple of classrooms of the University of Rome. The control is organized by adopting a BUS system with "distributed intelligence" without a central and with smart actuators. The control turns on/off and regulates the lighting output of two classrooms, according to the actual presence of activities and to the actual availability of daylighting. A classroom was arranged with a light solution consisting in “on-off switching” control and not changing the luminaires, a second classroom was arranged with an advanced solution consisting in the replacement of the luminaires with a “dimming” control. A third class identical to the other two was taken as a reference to compare the results, in fact the architecture includes a supervisory system that allows a remote meter of the energetic values for the three classrooms. The paper shows the results of a year of monitoring campaign and compares the results with the energetic evaluation done by the a suggested tool based on the Standard EN15193 methodology.
