The architectural lighting design process follows the same project steps as the architect or interior designer would by following an SD to CD trajectory. While most projects involve the lighting designer from the beginning, there will be times in which the lighting designer is approached after the project is in the design development or just before the construction documents are prepared. Lighting is essential to the perception of the space, and the sooner the lighting designer is involved, the more foresight they can give into architectural features and lighting needs for different color palettes.
In the same way that light needs material to reflect off, a lighting designer will need a collection of information before they can proceed. Generally, just having the architectural drawing set will not be enough. The lighting designer will also need to know additional information, such as the furniture placement, shelving or millwork installations, and any decorative fixtures locations. Keeping this idea, the lighting designer will also need to know any alterations to the designs of the space. Even minor changes in the architecture, millwork or color scheme could mean a better lighting design solution is available or necessary. Consolidated packages with finalized updates are helpful, with the understanding that the lighting design may suggest additional architectural alterations as well.
After selecting the qualities of light, a lighting designer will then designate each type with a symbol. The variety of these symbols are positioned on the drawing plan as part of the architectural drawing set. Generally, the lighting designer will also select particular architectural fixtures and specifications for the project.
