This article presents a study on the measurement of visual comfort of lighting for interior environments. As presented in the introduction, the proposed approach recreates in laboratory a realistic working places and living-room configurations in order to study visual comfort with subjective ratings and physical measurements in a controllable and reproducible way.
Hereby a subjective experiment is described, conducted at LNE with the participation 50 individuals. Four different tests are fully described reporting procedures, testing facilities and subjective results.
A model for assessing visual comfort is proposed and analysed. This model considers two parameters categories: discomfort parameters (related to specific effects such as glare and flicker) and comfort parameters (referred as general visual quality). All parameters are derived from spatial and spectral distribution measurements of interior lighting conditions. Finally, the obtained results with the proposed model are presented and commented with regards to subjective rating.
