Role of the model user in results obtained from simulation software program

Within the framework of the validation methodology of our computer software CLIM2000, we asked 12 users to do the same validation exercise (prediction of energy consumption of a residential house) in order to evaluate the influence of the model user on the imulated results. The first part of this article describes the conditions in which this exercise was carried out. The second part of this article presents the results in two ways : a comparison with the average value of the results and a comparison with the results obtained from a reference modelling. Then, an analysis of the discrepancies in the results is also presented. Finally, we tried to give some remedies to reduce such errors in the future.
