In the EUREF research campus “Mobility2Grid”, research is carried out on the implementation of a sustainable energy and mobility development in urban areas through the utilization of renewable energy sources. During the first phase of the project Mobility2Grid different scenarios for the EUREF district with electricity generation from renewable energy sources and optimisation approaches for stationary batteries and electric vehicles were evaluated by using a simulation framework with regard to the degree of self supply and CO2 emissions. Selected results are presented. In this context, buildings will be classified as components of an overall energetic system, and can actively contribute to control the energy consumption in dependance of energy production and thus smooth load fluctuations. The integration of a thermal model into the energy optimisation and simulation environment associates especially storage, energy conversion, the heating network and the heat load displacement potential. Building Information Modeling (BIM) supports different analyses to improve the overall energetic system. It links the building characteristics with the data of utilization and provides information for building energy simulations. The aim is to determine the building loads and the storage capacity of one or more buildings, depending on building condition, operation and also considering alternatives.
