In reaction to the European Energy Performance of Buildings Directive (EPBD), existing and newlylanced standard developments by CEN (European Committee for Standardization) were harmonizedand synchronized, resulting in a set of about 50 standards addressing different aspects of the EPBDand the implementation of an overall building energy performance calculation method. A few of themaddress simulation issues:An overview of these is given, focusing on one standard covering system related aspects for buildingswith cooling, humidification or dehumidification. It allows for any calculation method, including hourlysimulations, as long as the general requirements are fulfilled. In the HVAC domain the variety ofsystems is very large and there is no general method able to cover this. Simplified calculations maycover certain areas, and the standard gives indications when this is acceptable. Validation aspects areaddressed in a very preliminary way, since this is an area for more research.
