Validation of the Algorithms Developed for Preliminary Prediction of Daylight Distribution in a Toplighted Atrium
Abstract
Empirically based preliminary prediction
algorithms were recently developed for different
atrium types under various diffuse sky
conditions. In the case of toplighted atriums,
these algorithms were developed to predict light
levels on the horizontal floor and on the
vertical wall surfaces of the atrium. However,
the actual building atriums measured to assess
these algorithms in a full-scale setting were
four stories high or lower.
This study presents an investigation of the
validity of the developed algorithms using
full-scale measurements in two four-sided
toplighted atriums 11 and 14 stories high
respectively. The measurements were made over
several days in the two large atriums of the
Anatole Hotel in Dallas, Texas. These data are
compared with the algorithm predictions, and the
usefulness of the prediction models is discussed.
