This report focusses on giving an answer to the question of whether an interactive lighting design can promote social interaction in a public space. Following the procedural model introduced by E. K. Hansen and M. Mullins, a trans-disciplinary research was conducted with a scientific, technical and creative approach, relying on the focus areas presented in the Copenhagen Lighting Masterplan and the concept of lively space, within the image and identity of Copenhagen, to propose a design to be implemented at Lageliniekajen. The proposed solution aims to improve communication between visitors and the space, and among the users. Tests were conducted to determine specifications for light sources, light distribution and correlated colour temperature to be applied in the interactive design. Problems regarding safety, security, light pollution, historical preservation, communication, and engagement with the site were solved through the design projected.
