Within the exhibition "Architecture of Light", the students’ association of the Faculty of Architecture in Parma "SEGNIdSEGNI", in collaboration with Parma Urban Center, proposed on Thursday 8th September 2011 a three voices-conference to which Filippo Cannata took part along with Roberta Amirante lecturer at the Faculty of Architecture of the University of Naples "Federico II", owner of the Course in Architecture and Urban Design, and Sergio Pone, architect and associate professor of Architectural Technology at the Department of Urban Design and Planning, owner of the Laboratory of Construction and lecturer of Executive Design in the Course of Master Degree in Architecture, and member of the teaching body of the Ph.D. in Architectural Technology at the same University. The conference, fulcrum of an initiative involving European intellectuals, architects, photographers and historians, was introduced by Aldo de Poli and Dario Costi, lecturers at the Faculty of Architecture of the University of Parma, focused on the theme " Lights of the City (or "Naples with the lights on"). The lighting project of Piazza Mercato in Naples, that was the subject of a thesis discussed in the Neapolitan University to which Filippo Cannata participated as co-rapporteur, became the starting point for an analysis of the trends over time of the principles and forms of urban lighting. Today it is aimed not only to ensure the conditions of visibility for safety, the smoothness and ride comfort for motorists or the pedestrian crossing, but it is targeted more precisely to upgrade and characterize the public space with its specificity, considered not as a simple space of connection between private premises, but a living place, during the day as well as in the night. Above all, under this new approach to the theme of light - Cannata says - we are witnessing a growing interest in the needs of the user of this space, the end user of the lighting project, the citizen, that is with his uses and his perception an integral and substantial part of the system light- environment. Therefore a lighting project is appropriate when it provides a lighting that is different in relation to the different functions of a space, so to the uses made by people who interact with it. The lighting at the service of the user and the user in the center of the reflections on the lighting project seem to become the terms of a new ethic of urban lighting, which obviously includes the respect of other important principles such as environmental sustainability and energy savings. The challenge is to achieve the maximum of efficiency and responsiveness to the objectives with economic energy and environmental costs that are the lowest possible. New technologies seem to offer important contributions in this regard by encouraging the change. It's the end of a long era. In every end there is a new beginning. And in every beginning there is a meeting of past and future.
