Abstract

Can patterns be seen in the subject’s responses to and preferences for daylight and artificial light when staying in the indoor environment? The research behind the paper investigates if gender, personality and visual performance are possible factors for the build up of subgroups with a similar need for light. It is also investigated if the individual need for light in the ordinary reading situation and for ambient light can be defined by the use of the Burrell’s test (BT) and the visual comfort test (VCT) and if it is possible to, based on the results from the BT and the VCT, construct a light identity. Results show large interindividual differences among subjects in preferences for light.
