| Resumen |
The natural illumination of indoor premises is determined essentially by the luminance of the sky. The distribution of the mean effective luminance serves as a basis for calculating the illumination level. Description of an apparatus for measuring luminance with recording on punched tape and automatic scanning of the sky (optical and mechanical elements and measuring procedure). Comparison of luminance values shows that an "average" sky is distinctly brighter than an overcast one, and that luminance depends on the direction faced. As a result, the duration of useful periods of daylight for the purpose of lighting is longer than that hitherto employed in calculations. |
