  CODYRUN is a software for computational aeraulic and thermal simulation in
buildings developed by the Laboratory of Building Physics and Systems
(L.P.B.S). Numerical simulation codes of artificial lighting have been
introduced to extend the tool capacity. These calculation codes are able to
predict the amount of light received by any point of a given working plane and
from one or more sources installed on the ceiling of the room. The model used
for these calculations is original and semi-detailed (simplified). The test
case references of the task-3 TC-33 International Commission on Illumination
(CIE) were applied to the software to ensure reliability to properly handle
this photometric aspect. This allowed having a precise idea about the
reliability of the results of numerical simulations.
