Integrated Photometric Descriptors for Lighting Quality Research & Recommendations

Since the workshop held at the 23rd Session of the CIE in 1995, lighting quality has been established as one of the fundamental problems in lighting design, research, and education. The workshop at the 24th Session addressed a topic identified by delegates at the First CIE Symposium on Lighting Quality, held in 1998 [1]: the need to refine our definitions of luminous conditions to develop useful descriptors of the luminous field. Agreement about these photometric descriptors is a necessary first step to the development of research programs to advance understanding of the effects of the luminous environment on human behaviour, mood, and health, and to the development of recommendations for good-quality lighting design.
