Colour and light and the human area for visual comfort

Paper in proceeding, 2010

In the study three interaction models man, light, colour and space in three descending levels of quality was designed from the preferences of the Lighting Designer. The subjects recognised the three descending levels of quality and evaluated them to a high extent in the same way as the designer. The room with the highest quality of interaction according to the lighting designer’s preferences, Room number 2, was the most appreciated by the test subjects. A suggested reason for acceptance among the subjects is the possibility to stay within or close to visual preferences here measured in the visual comfort test. A second reason for the acceptance for Room 2 is the room being within a general preference for soft contrasts, absence of glare, a low level of visual variation. A third factor is a general preference for light distribution generating a welcoming atmosphere due to the higher level of vertical illumination compared to the other two rooms in the study. The results indicate that there is despite a vast spread of visual preferences among the subjects, a human area for colour and light and visual comfort equivalent to other indoor climate factors.
