Light and Dark Rhythms

Light and Dark Rhythms - Daylight and Artificial Light Qualities for the Design of Future Spaces

The research project investigates lighting quality under a human perspective via literature reviews and experimental work.

The focus of the experimental work is the impact of variation of spectral properties and intensity on humans’ perceptual system. This will be accomplished by creating new experiences that are based on the interplay between artificial light and daylight, and by the use of psychophysical methods and novel measurement and assessment methods. The outcome of the research will be of importance for the prediction of future lighting design programmes and policies.

We believe light and dark rhythms are necessary for the development of a creative, performative and healthy society.
