INVESTIGATION OF THE APPLICABILITY OF THE INDEX N×LC FOR ESTIMATING ACTIVE-CALM IMPRESSION OF LIGHT ENVIONMENT

Abstract

In our previous study, we proposed an index N×LC for estimating active-calm impression of lighting space. In this study, we examined the applicability of the index for more various lighting environments. By the experiment using a scale model, we obtained various lighting patterns produced by subjects for each of the designated active-calm evaluations. Then we calculated the N×LC values for each lighting pattern and investigated the relationship between the index values and active-calm evaluations. The results showed that the N×LC values related with active-calm evaluations for various lighting environment.
