SubjectLighting and health
AbstractIn the late 1990s, CIE began to shift its emphasis from lighting for visibility to a more broad definition of lighting quality, encompassing human needs, architectural integration, and economic constraints (including energy) [41]. Human needs, as defined here, include lighting that is appropriate to maintain good health, as well as lighting for visibility, task performance, interpersonal communication, and aesthetic appreciation.Among other developments, this definition reflects the many demonstrations that there are nonvisual, systemic effects of light in humans. Specifically, controlled laboratory and clinical studies have demonstrated that light processed through the eye can influence human physiology, mood and behaviour. These findings may provide the basis for major changes in future architectural lighting strategies.The report of CIE TC 6-11 summarises the literature in this rapidly-developing area through December 2001, including the neurophysiology, neuroanatomy, behavioural effects of daytime and night-time effects of light exposure in healthy people, and therapeutic effects of light. The report concludes with preliminary guidance concerning healthy lighting and how it might be applied architecturally. This presentation will focus on the possible architectural applications of this area of research, for lighting interiors occupied by day and by night, as a step towards lighting recommendations that respect the broadest definition of lighting quality.
