This dissertation proposes an extended evaluation methodology with respect to CO2-emissions for the holistic and time-resolved assessment of energy systems at building level that considers the different system levels, their coupling and technical restrictions. In this context, the growing integration of renewable energy sources and the introduction of novel, efficient technologies for heating in the building sector will cause fundamental changes in the operation, control and evaluation of the energy system. The operational flexibility of building energy systems by thermal and electrical storage is included in the presented evaluation method to enable a comparative assessment of the system´s performance. Results demonstrate, that a grid-supporting operation mode of building-energy systems is possible, enabling an enhanced integration of renewable energy sources inside the grid and consequently influencing the allocation of CO2-emissions. Additionally, the results indicate, that grid-supportive measures of building energy systems have not been sufficiently considered in former evaluation methodologies. The presented evaluation method is embedded in a flexible simulation environment to study different scenarios, taking a step forward to a possible integration in evaluation standards and regulations.
