"Higher ceilings allow the use indirect lighting, which is much healthier and reduces glare"
About this Quote
“Higher ceilings” sounds like a neutral design preference, but Jahn is really making a moral argument disguised as a technical tip. He links a spatial choice to bodily consequence: indirect light becomes “healthier,” glare gets “reduced,” and suddenly ceiling height isn’t an aesthetic flex, it’s a public health intervention. That’s classic architect rhetoric at its most persuasive: take something expensive and structural, justify it through the everyday comfort of eyes and skin, and you’ve turned a cost line into an ethical line.
The intent is pragmatic. Higher ceilings give designers room to bounce light off surfaces, soften contrasts, and avoid the harsh, retina-hammering hotspots that come from fixtures aimed straight down. But the subtext is bigger: modern life is already an assault of screens, reflections, and overlit interiors; architecture can either amplify that aggression or buffer it. “Glare” here isn’t only an optical phenomenon. It’s a metaphor for the way bad buildings demand attention, impose themselves, and exhaust you.
Context matters: Jahn came up in the late-modern/hi-tech lineage where glass, steel, and spectacle dominated. Those gleaming surfaces look great in photographs and brutal in real use, because glassy modernism often produces the very glare he’s warning against. His point reads like a quiet corrective from inside that tradition: if you’re going to build bright, transparent spaces, you owe occupants the humility of comfort. Indirect light becomes a way to civilize the monument.
