Abstract

This paper presents initial findings of a sky measurement program currently in progress at the National Bureau of Standards. Measurements are reported on sky luminance and illuminance and how they relate to horizontal solar radiation and sun position. Correlations are presented relating horizontal illuminance to horizontal solar radiation, and zenith luminance to solar altitude. These empirical models are particularly suitable for use in daylighting energy studies since they are based on existing solar data currently available on standard weather tapes.
