Lighting Objectives and Demands of Future Buildings

摘要

The objective of the research was to find out the utility and defects of the present lighting recommendations. One specific aim was to find how the present recommendations take into account the lighting demands of older and partially sighted people. A primary objective of the research was to find out how luminances instead of illuminances could be used as a basis for lighting assessment and lighting recommendations. The application of visual performance in lighting dimensioning was also studied. Experimental measurements were carried out to examine the effects of lumiance and light spectrum on visual acuity. Young normally sighted, older people and partially sighted subjects participated in the measurements.
