Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
(Ré)concilier éclairage urbain et environnement nocturne : les enjeux d’une controverse sociotechnique
2014
International audience; Our paper explains the birth of an environmental problem, i.e. light pollution, viewed as a socio-technical controversy. Supported by the actor-network approach, it traces over forty years the conditions of its emergence, transformation and dissemination to local, national and transnational levels and through various professional disciplines. Schematically, “environmentalists” uphold a holistic approach of “nocturnality” and define artificial light as a pollutant. Facing them, the “technicist” defends a segmented approach and defines artificial light as a nuisance. The introduction of this controversy into the political agenda leads to institutional decisions that gr…
Blaming the Light, Claiming the Night. Actors, Issues and Effects of Lighting Conflicts in France since the 1980's
2014
International audience; Regarding environmental issues, conflictuality is a privileged way to reach the political arena. "Naming, Blaming, Claiming": three steps that make the controversy emerge, constitute the public issue, then bring it to the politi- cal agenda. These three stages are clearly identifiable in the history of night protection associative movements. These movements emerged in the 1970's in the United States of America, quickly disseminated enjoying a broader context of environmental thinking. Conflicts related to artificial lighting are structurally akin to conflicts of contradictory uses of a single resource: the night. For some - the technicists -, the night is the "good-s…
The colour of light for urban spaces
2013
Light in urban spaces was first introduced to prevent crimes against both people and properties and, while there is no study that confirms crimes' reduction in lit spaces, it is undeniable that people feel safer in lit urban spaces. Over the years it became evident that light can also improve the liveability of cities and enhance their characteristics, therefore in the last years a growing attention was paid to urban lighting design taking into account the environmental impact and energy saving requirements too. The will to use the lighting design project to improve the liveability of historical centres it’s clear: the city during the night is no more conceived like a sum of lit architectur…

Getting night lighting right taking account of nocturnal urban uses for better-lit cities
2018
Translated by Oliver Waine; International audience; Innovation in contemporary urban lighting has increasingly been driven by issues of sustainability. While environmental concerns focus attention on energy savings and reducing light pollution, taking account of how people use public spaces is important too, as artificial light can then be adjusted to actual needs. Following the pioneering work of Roger Narboni and Luc Gwiazdzinski, Samuel Challéat and Dany Lapostolle make the case for dedicated nocturnal city planning.
Luci e ombre sulla piazza. Cicliche trasformazioni di uno spazio pubblico
2010
Con questo articolo intendo mostrare quali possano essere le interazioni che intercorrono tra due elementi fondamentali dello spazio urbano, il suolo e l’illuminazione, nel definire il senso di un luogo. Generalmente considerate due presenze “ovvie”, quanto meno scarsamente problematiche se non a livello di mera funzionalità pratica (soprattutto nel caso della pavimentazione) in questo lavoro vengono considerate come elementi fondanti del funzionamento semiotico dello spazio urbano. Con l’esame di un caso, quello di un’importante piazza della città di Palermo, piazza Politeama, voglio dimostrare come le condizioni di illuminazione e l’organizzazione del suolo di un preciso luogo siano in gr…
Smart lighting in a historic context: a case study
2017
Purpose The purpose of this paper is to address a project for lighting an old town in Italy. Its originality lies in the holistic approach that aims to fulfil several objectives. One is to reduce energy consumption by using efficient lamps and advanced control systems; the second one is to make the network viable and useful for many purposes by integrating ICT devices; the third one is to provide a new identity to the older part of the city by using new technologies and design concepts; while the last one is to ensure street and pedestrian safety according to codes and standards. Design/methodology/approach The plan of the city of Bagheria and the stock of luminaires of the city are analys…
