The EPBD prescribes an energy performance certificate for buildings. According to the national implementations of the EPBD for non-domestic buildings the specific data of the building will be gathered during the certification process and combined into a multi zone model describing building
and building systems from an energetic point of view. Such a model can not only be used for certification but also contains valuable information for a continuous evaluation of the energy performance of the building (continuous commissioning).This paper describes the concept developed
at ennovatis and gives first results of its application.
