3-59: The integration of daylight and electric lighting – photometric, colorimetric and radiometric requirements for the spectral design of indoor lighting

This TC will define requirements for a lighting design approach that considers human comfort and wellbeing, as well as energy efficiency, taking into consideration the light spectrum in addition to the conventional design criteria based around illuminance or luminance. The approach will build upon the integration of daylight and electric light, and take account of the spectral sky condition, the spectral properties of windows and interiors, and the spectral properties of electric lighting.
