Validation of a dynamic simulation program according to EN ISO 15265

Abstract

EN ISO 15265 is a standard describing validation procedures concerning dynamic simulation programs for evaluation of energy demand in buildings. The validation procedure comprises 12 tests altogether: 4 introductory ones and 8 proper validation tests differing with the assumptions concerning the partition construction, the thermal mass, window shading, external gains and functioning of the installation systems. Some procedures, for instance the calculation of solar radiation incident on the vertical planes, are not clearly described in the standard. The paper presents the discussion of possible interpretations of the procedures included in the standard and the results of validation of a simulation program based on the control volume method.
