Algorithm for calculation of daylight factors in streets

Summary

Presents algorithms for the calculation of sky components and daylight factors in linear building structures using the solid angle projection method. In order to estimate the precision of the calculations, two sky models are used - the uniform sky and the CIE overcast sky, both giving illuminance on the horizontal plane. Also compares daylight factors calculated for CIE overcast sky with daylight factors measured in a physical scale model of a linear atrium, in an artificial sky of the mirror-box type.
