Expanding space with light: making foyers look brighter and larger

Use vertical illumination to make foyers brighter, more spacious, and easier to grasp. Evenly lit walls provide orientation, reinforce a welcoming spatial impression, and emphasize materiality.

Indoors, wallwashing accentuates architectural surfaces. Outdoors, façade lighting structures squares and open areas and defines clear spatial boundaries

The most important points

  1. 1At the same illuminance, illuminated walls create a far greater impression of brightness than horizontal surfaces, because they lie directly within the natural field of vision.
  2. 2Pay attention to the reflectance of surfaces: exposed concrete requires twice the illuminance of a white wall, and dark wood six times as much.
  3. 3Use brightly washed walls to provide orientation, since the eye perceives the brightest surface first and automatically attributes significance to it.
