Empirical whole model validation case study: the PASSYS reference wall

The methodology for validation of Building Energy Simulation Programs developed within the CEC concerted action PASSYS by the Model Validation and Development subgroup was presented at the IBPSA conference "Building Simulation '91" (Jensen and van de Perre 1991, Palomo et al 1991). Part of this validation methodology is a methodology for Empirical Whole Model Validation. Several case studies using this methodology have now been carried out. One of these case studies implies the investigation of a data set obtained in a PASSYS test cell with the PASSYS Reference Wall. The paper describes this case study in order to demonstrate the PASSYS methodology for empirical whole model validation-especially the part of the methodology dealing with comparison of measurements and predictions.
