Proposal for identifying light pollution sources in private spaces

Abstract

Artificial light has transformed urban life by extending activities into the night, but its disorderly use has generated light pollution - an environmental problem that is still little recognized. Characterized by excess, misdirection and use at inappropriate times, this pollution affects human health, wildlife, safety and the night landscape, as well as increasing energy consumption and reinforcing social inequalities. This article proposes a methodology for identifying and quantifying possible sources of light pollution on the façades and external areas of buildings in the Praia do Canto neighborhood, Vitória - ES. The methodology involved a literature review and empirical research with an exploratory approach, focused on identifying the main buildings that contribute to light pollution in the Praia do Canto neighborhood, in Vitória - ES. Of the 21 buildings analyzed, 13 showed some degree of contribution to light pollution, especially on the façades and sidewalks, while 8 showed no polluting sources, showing the viability of more sustainable lighting projects even in vertical areas. The research revealed that light pollution is a reality in the neighborhood, caused mainly by the lack of technical criteria and specific policies, highlighting the urgent need for regulatory guidelines, educational actions and incentives for the use of efficient technologies.
