In the course of the declining heat energy demand by the improvement of building insulation standards, alternative energy concepts as well as cooling systems gain more denotation. At the same time, the progressive expansion of power and heat generation from renewable energy sources requires the storage of energy. A solution approach can be the utilization of the heat capacity of the building structure.

Thermally activated building systems (TABS) are directly electric or hydraulic heating and cooling systems, which are installed in the room enclosing areas. The aim of this thesis is to investigate the advantages and disadvantages based on the characteristics of the different positions of TABS in the room enclosing areas. For this reason the focus was on room comfort, regulation capability, storage capacity and energy efficiency. With the investigation of the TABS in a room, with idealized boundary conditions, the prevailing dynamic effects for the case of heating and cooling were analyzed.

In addition, the analysis was carried out on the entire building in order to include the interactions between the rooms under realistic boundary conditions. An assessment system was developed with the perception from the simulation results, so that the multitude of parameters can be systematically evaluated. The results provide an overview in which evaluation criteria the advantage apply for the various positioning options. In the last step, the possible applications were discussed on the basis of the advantages and disadvantages.
