TA1 How to design for user wellbeing: co-ordinating natural light with circadian lighting

10:00 - 10:45

How can we design & deliver lighting in buildings to promote comfort in use for the occupants? How do we balance just replicating the natural rhythms of daylight and manipulating human responses, e.g. to extract more learning in children, or more productivity for employers? When is it too much? It’s understood that shift work can have a detrimental impact on health, and maybe careful lighting options can help a little. These broader, non-visual effects of lighting can be powerful, and should be considered in any lighting project.

• What are the ethical implications of altering circadian rhythms, and what are the long-term affects?
• Practicalities of melanopic lighting to supplement daylighting
• How to use lighting metrics for best outcomes
• What are the benefits of the WELL Building Standard’s Equivalent Melanopic Lux as a proposed alternative metric?
