Lighting design is often reduced to basic illumination levels, ignoring the complex relationship between human perception, health, and the built environment. This narrow focus misses the opportunity to create spaces that truly support occupant well-being and productivity.
This episode explores the critical shift from traditional illumination methods to modern, evidence-based lighting design. We discuss why a multidisciplinary approach is essential for high-performance buildings and how new metrics like Main Room Surface Excellence are changing how we define quality lighting.
Professor Kevin Kelly, Emeritus at TU Dublin and past CIBSE President, joins us alongside Dr. James Duff, Associate Director at Arup, to break down the science of light. They discuss the urgent need to prioritize daylight and quality over sheer quantity, drawing on years of research to provide actionable insights for practitioners.
THINGS WE SPOKE ABOUT
Defining the role of an independent lighting consultant.
Shifting from illumination efficiency to illumination hierarchy.
The impact of blue light and glazing on human health.
Why modern standards often prevent bad, not good, outcomes.
Designing lighting for biodiversity and perceived safety.

QUOTES
Everything you see, you see, because it's illuminated, so you'll see nothing unless it's illuminated, whether it's by daylight or artificial light. - Kevin Kelly
Lighting is interesting in that you get little fingerprint on very many things. - James Duff
At best, I think lighting is undervalued, and at worst, I think there's an indifference to lighting. - Kevin Kelly
It's so common to hear there's 200 lux, there's 100 lux, that's 300 lux towards something that's a little bit more holistic. - James Duff
