Doel van het onderzoek
Lighting conditions, the intensity as well as the colour, influence thermophysiolgical responses and thermal comfort.
Onderzoeksopzet
Subjects are exposed to lighting conditions for 5 hours. The different lighting conditions are provided at different days. Each subject has to participate in two experimental days, and therefore will be exposed to two lighting exposures.
Onderzoeksproduct en/of interventie
During the experiments the lighting conditions vary in intensity (bright and dim light) and in colour (long wavelength and short wavelengths). Experiments will be done under mild warm, mild cold and thermo neutral temperatures.
