Nocturnal Urban Sociology and Light Sobriety

Abstract

Associated with the definition of the lighting development coherence scheme of the metropolis of Nantes, France, this chapter contributes to identifying the stakes of better energy and light sobriety in the management of its public lighting park. The research focuses on how to raise awareness and involve the users of public spaces in the evaluation and production of nocturnal ambiances. It includes an experimentation of field survey dedicated to the evaluation and iteration of a method for the collection of sensitive indicators. Beyond its analytical part, this chapter proposes an unprecedented digital mapping tool to in real time collect physical and sensitive indicators. The research addresses the concept of expertise of use, complementary of political and technical ones that currently govern public lighting. The results confirmed that the pedagogy of light sobriety, regarding the challenge of energy and light sobriety originally pursued through an approach of awareness to street lighting for users, is ultimately determinant in the renewal of street lighting policies.
