Free lighting planning is neither neutral nor complete – and rarely conceived from a design perspective. Whether reduced by the electrical planner to compliance with standard values or provided as a sales argument by a manufacturer: what appears to be a service usually costs more later – due to a lack of competition, lost quality of stay, and subsequently even renovation costs.
The truly decisive lighting effects – visual, biological, emotional, atmospheric – cannot simply be „retrofitted“. They are created in the design process. In the early phase of a project, when structural openings, room depths, materials, and usage scenarios can still be actively shaped.
