Abstract

This paper studies the impact of well geometry and surface reflectance (including
the wall reflectance, the floor reflectance and the reflectance distribution of wall) on the distribution of vertical daylight level across the atrium well walls under a CIE
standard overcast sky. By the comparisons with scale model measurement, the vertical daylight factors on the wall calculated using Radiance are validated. More simulated vertical daylight factors across the wall in an atrium with various geometries (WID), reflectances and reflectance distributions are given. From the results the attenuation and distribution of the vertical daylight levels
on the wall of a square atrium are displayed. Some conclusions for supporting daylighting design in atrium buildings are listed.
