| Abstract |
Providing appropriate illuminance level is important for occupant’s productivity and visual comfort. Many attempts have been made to
quantify occupant’s preferred illuminance level as well as occupant’s lighting control behavior. In this study, the authors performed three
uncertainty analyses of indoor illuminance level and control behavior in 17 residential households. The degree of such uncertainty were
analyzed using Wasserstein Distance, a difference in mean/max illuminance and the probability of lighting control behavior. It was found that
indoor illuminance level and lighting control are highly stochastic. This study indicates that a new approach is required to better understand
the level of preferred indoor illuminance levels and lighting control in a living room space of residential buildings. |
