Abstract: The goal of this research, for the master’s dissertation: “Towards a new design methodology for hybridGEOTABS!”, was to develop an easy-to-use method that can be used by practitioners to determine the optimal nominal power of hybridGEOTABS in an early design stage. GEOTABS is an acronym in which GEO refers to geothermal heat pumps coupled to thermally activated building systems (TABS). Additionally, a secondary fast-reacting system is added, making it a hybrid system. Analysing the pre-simulated large database of the hybridGEOTABS Horizon 2020 project shows that a correlation can be derived between the 24h moving averaged peak thermal load of the building and the optimal nominal system powers of the heat pump and the secondary system. This corelation forms the foundation of the new corelation method.
