English abstract:
In this paper, we present the final results of a comparison of lighting energy performance in two groups of
spaces, namely lecture rooms in an academic building (Faculty of Engineering, University of Trento). The
study was carried out at the "CUnEdI: Centro Universitario Edifici Intelligenti" of the University of Trento. The
first group of three lecture rooms is operated in a conventional manner: luminaries are switched on and off
manually by the users. In the second group (spatially similar lecture rooms in the same floor/building and
with the same orientation) different automated control regimes were implemented and monitored over a
whole academic year. In all 6 lecture rooms (with both conventional and automated operation regimes)
occupancy sensors and power consumption meters were installed to monitor these parameters separately
for each lecture room.
In the referred research a new design methodology has been developed and verified, that relates energy
saving and visual comfort. The analysis of the energy saving potential of automated lighting scenarios,
carried out using specific standardization techniques, have been monitored in real use conditions and not in
controlled laboratory environment, in order to prove the automation systems efficiency in operating time.
