possible to check compliance with the specifications and to identify the cause of user discomfort (insufficient lighting, glare). It can also enable comparative evaluations of innovations, for example, a new coating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This type of service is part of the research on improvements to public lighting, roads, access to buildings, etc. Its purpose is to help architects, design offices, and communities or energy syndicates to develop comfortable and effective solutions for users.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cities are testing different solutions to reduce the energy consumption of public lighting. This also involves the development of new coatings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To highlight the improvements made by these new coatings in terms of visual perception and safety for users, PIS\u00c9O carries out measurements of lighting, uniformity, and luminance before and after the implementation of these new coatings. These measurements could also make it possible to determine whether reducing energy emitted by road lighting while maintaining the luminance is possible, thus saving energy.<\/p>\n\n\n\n<p
