Daylight in city interiors
How does daylight contribute to visual quality and comfort in interior spaces in contrast to artificial lighting?

In today's world where cities face densification and problems of area shortage, how can we rethink daylight conditions in urban living?

Daylight in city interiors

Daylight (in the same way as windows that open) contributes to human comfort by being variable in quality and quantity. Artificial light, on the other hand, has no "variability" and so is dead and this deadness causes unease in humans.

In northern parts of the world, when winter comes, people go to work in the dark, work in artificial light through the day, and then go home in the dark.
Many people are seriously disturbed by this lack of sunlight/daylight and become depressed.

The tropics are not affected by either axial tilt or by shorter and dimmer light during the daytime. Therefore, this is much less of a problem, because even if people worked during the whole day in artificial light, at least they get up in sunlight and return home in sunlight.
