How to light up a building

The Building Lighting Charter in the Principality sets out common rules to control public and private lighting.

This tool presents the general requirements relating to luminance, colours, beams of light, maximum energy consumption, operating times and specific requirements related to categories of buildings.

Two main categories of buildings that can be lit up have been identified (each of which is divided into sub-categories, established according to certain criteria):

• Noteworthy buildings and noteworthy groups of buildings that are part of the larger urban landscape
• Buildings located in areas that are busy at night

Outside these two categories of buildings, any request to light up a building will be subject to case-by-case examination, to determine the relevance of the project for the Principality's night-time image.
