Abstract

When comparing ditital simulations with experimental field measurements, we often find references associated with a large margin of uncertainty. In other words, to what degree do the results come close to the real situations studied? Indeed, a number of research studies attest to the significant difference between the two simulated and real situations. This work consists of two comparative experiments: i) Comparison between the results of the digital simulation of the levels of illuminance on a work plan carried out by the two software Radiance 2 BETA and Ecotect5.5., As well as ii) Comparison of the results obtained by a digital simulation of the levels of illuminance on a work plan carried out by means of two software programs, namely Radiance 2 BETA and Ecotect 5.5. A simulation by models (models) under a clear sunny sky. The results obtained prove differencees in the comparison. The most important ones are presented by the discrepancies between the data measureed and simulated by the Ecotect 5.5 software. The data measured and those simulated by the Radiance 2 BETA software have smaller deviations.
