Validation of the CLIM2000 software program by using analytical verification

Up to now, within the framework of validation of the global building energy simulation software programme CLIM2000, we have not focused on analytical verification. Indeed, the scientific literature is not verbose on this subject due to the fact that only few thermal problems have analytical solutions. In the framework of International Energy Agency (IEA) Solar Heating And Cooling (SHAC) Task 22 (Building Energy Analysis Tools), a working document was established identifying and summarising analytical tests as verification and debugging tests for building energy analysis simulations. This paper presents the results obtained with  CLIM2000   after   implementing   all   these analytical tests.
