| Abstract: | To verify the accuracy of lighting simulation programs, the International Commission on Illumination (CIE) published technical reportCIE 171:2006—Test Cases to Assess the Accuracy of Lighting Computer Programs, which can be applied to validate lighting simulation tools. This article reports the performance ofDIALux4.12 andDIALux evo4.1 against the analytical test cases of CIE 171:2006. Both programs show very good agreement with the reference values in cases with point source.DIALux4.12 yields noticeable errors at receiving points with small configuration factors, in cases with area source. Both programs show good agreement with the reference values in cases with diffuse reflection, respect luminous flux conservation, but do not respect variation in relative angular transmission due to varying incidence angles. Inaccuracies are found in daylighting scenes, particularly in the calculation of sky and externally reflected components. It may be of common interest for the CIE to amend the current document and publish a new version with possibly a new series of test cases. [ABSTRACT FROM PUBLISHER] |
