The perceived atmosphere in a space is to a large extent determined by the illumination of the space, which usually is a combination of artificial lighting and daylight naturally entering the room. In this study we investigated how the presence of daylight affects the perceived atmosphere of a light ambience both in a real illuminated space and in a visualization of the space. The perceptual accuracy of these visualizations has been demonstrated in previous studies for artificial interior lighting, but not yet for the contribution of daylight to the interior lighting. Our results showed only a relatively small effect of the contribution of daylight both on the perception of light and the perception of the atmosphere of an interior light ambience. Possibly, adaptation plays an important role in this finding. Further, we demonstrated that the perceptual accuracy of visualizations containing daylight was for the majority of the light and atmosphere perception attributes similar to visualizations showing only artificial interior lighting.
