Light influences the image of a city. Modern and innovative lighting concepts improve and leave a lasting impression of a city. Public lighting, architectural illumination and concerns of commercial lighting need to be balanced in order to create a coherent appearance of the urban realm. A lighting masterplan defines and controls the various bearings and proceedings.

While decision makers and interest groups are closely involved in the process, guidelines and recommendations (general lighting approach) for urban spaces can be derived from the lighting concept. As a result the lighting concept can provide objectives with different focuses. Lighting design not only guarantees compliance with road safety regulations, economic feasibility and environmental sustainability, but it considers design aspects as well. The target is to strengthen the identification of citizen and business people with their city and to enhance identity for eyes observing from outside.
