Designing the Sensory City: Architecture, Light Pollution, and Urban Noise
For most of human history, night arrived as a planetary certainty. Darkness spread across landscapes, and the sky revealed thousands of stars. Today, that sky is disappearing. Artificial light spills upward from cities, scattering through the atmosphere and turning night into a permanent haze. Research mapping global sky brightness shows that more than 80 percent of humanity now lives under light-polluted skies, and the Milky Way has vanished from view for over a third of the world's population. The disappearance of dark skies is usually discussed within astronomy, but the sources of that change are deeply embedded in the built environment. Buildings emit light, reflect it through glass façades, and extend illumination far beyond their walls. In the technosphere, the vast system of infrastructures and materials humans have constructed, architecture now shapes both physical space and the sensory conditions surrounding it.
