Experimental validation for software DIALUX: application in CIE test Cases for building daylighting simulation
Résumé
DIALUX (www.dialux.com) is a freeware that simulate artificial and natural lighting outwards as well as inside the building. Interface of this software, functionalities suggested and outputs (realistic rendering as well as physical values) makes DIALUX widely used software in lighting design domains in Europe. Therefore, it was interesting to verify the accuracy of this software. While the software has already been tested with regards to artificial lighting simulations, there is no available information regarding its accuracy in daylighting simulation. Knowing that the software is already being used by consultancy firms for daylighting evaluations within green building design projects, it was important to assess daylighting functionalities in DIALUX. The reference data for the comparison measurements / simulation is based on experimental measurements to the scale model. Experimental study environment is an artificial sky imagined by the ENPTE (Ecole National des Travaux Public de l'Etat, Lyon, FRANCE) Laboratory. The recommendations used for experimental protocol are given by the task 3.33 of CIE technical committee (2005). One such study enables us to appreciate reliability of the software in relation to daylighting (natural lighting inside the building).
