Entry in the competition for the redesign of Swansea Square

Together with Huttereimann Landscape Architecture

Lighting scenes

  1. Early night hours (lighting plan at the top): full lighting level according to the programmed power as per the lighting concept.
  2. Late night hours (centre images): reduced, energy-saving lighting

By means of phase-controlled half-night switching (HNS), the luminaires are switched to reduced power operation (reduced luminous flux) during the night. This ensures a minimum lighting level to guarantee safety and orientation on the square. In areas without use or individual luminaires that primarily serve spatial modelling and atmosphere (e.g. at the “Schaukelwäldchen”), the lighting can be switched off completely in consultation with the City of Mannheim. Even in the late half of the night, the path area remains illuminated in such a way that the standard-compliant illuminance is maintained. Optionally, intelligent dynamic lighting control with radio-networked luminaires can be used to make the lighting dependent on use. To prevent vandalism and increase cleanliness and safety, the lighting in the kindergarten area is controlled by presence detectors.

Early night atmosphere

The downward light prevents a boring and monotonous lighting atmosphere and creates a lively carpet of light with nuances of light and dark. The luminaires can also set accents, e.g. grazing light on tree trunks without scattered light into the night sky. The tree-like shape of the selected luminaires matches the park landscape.

Late night atmosphere

According to the use, rear park areas are darkened, the path remains illuminated. The square is in darkness and only the main path is fully illuminated, for safety when crossing and for orientation.

Environment

Reduced illuminance levels and directed light from above at small half-scatter angles maximally reduce unwanted stray light and prevent unnecessary light pollution. The warm light colour of the luminaires in the square creates a stimulating and calm atmosphere. In addition, this lighting offers the highest possible level of insect and bird protection due to its low blue component. For optimal colour recognition and improved facial recognition, to increase safety and the subjective feeling of security, the area of the passageway and the café is illuminated with 3,000 K.
