A case study of high efficiency lighting system with advanced control system

The paper shows a case study of high efficiency lighting system realized in a library room at the University of Rome, Italy. The paper describes the lighting and control systems and highlights the impact on the energy performance. The adoption of LED modules and building automation approach permitted to obtain high level of performance both for lighting comfort and for energy performance. The library was divided in different zones. In each zone the optimal control was adopted. The energy results demonstrate that LED renovation coupled with electronic controls permit to obtain high values both of energy savings and performance.
