Role of Functional Illumination Urban Beautification: Qatar-Doha Road Illumination Case

Abstract

In this study, numerical analysis was made for 7 different road scenarios, which are called functional illumination in the architectural field. In functional illumination (road illumination) within the scope of the lighting masterplan, optimum illumination was provided in the simulation environment according to the criteria of the International Illumination Commission (CIE). According to the criteria of the CIE, the illumination system that does not adversely affect living things and the environment has been proposed by providing the limit values for the illuminance level, luminance, overall (resultant) uniformity, and longitudinal uniformity. In the architectural field, it is thought that functional illumination will increase the attractiveness of the city and contribute to architectural aesthetics by providing visual comfort.
