Transition Toward the Biological Effects of Light
A key shift is the transition from purely visual lighting assessment to non-visual effects. Today, we know that light influences circadian rhythms, hormone production, concentration levels, and mood, which is why lighting must now be designed more comprehensively. New standards introduce metrics and target values for integrating these effects while also unifying terminology and measurement methodologies for designing and evaluating lighting that meets the biological needs of the human body.
Impacts on Practice and the Future of Lighting
In practice, this means that architects, designers, and organizations should consider not only visual lighting standards, but also the effects on users’ health and performance when designing lighting systems. These new documents are guiding the global lighting market toward full-spectrum and biodynamic solutions that mimic natural daylight and support both performance and long-term health and well-being. At the same time, they create opportunities for new technologies that are expected to become the standard in modern buildings in the future.
