Abstract

The actual performances of Building Automation systems are often lower than the ideal ones. In order to investigate the actual performance of a Building Automation system for lighting control, a large stock of collected data, including indoor illuminance and absorbed electric power, have been presented and analysed in this paper. The measures have been taken during one year, in a laboratory located at the University of Palermo, where different lighting control systems, produced by two different manufacture companies, have been installed. As demonstrated in literature, many factors affecting energy savings’ evaluation in lighting control systems are the position and the typology of the sensors and their configuration. Furthermore, using the collected data, a set of indices has been calculated. It is able to test the performance of the systems in terms of energy efficiency and fulfilment of visual comfort tasks, according to different natural light availability, lighting system configurations and time scenarios. Finally, the performances of the two above lighting control systems have been compared
