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 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.
