A1) for obtaining solar heat stored in a fluid of a collector circuit and/or - at least one exhaust air thermal pump system (An; A6) for obtaining heat stored in a gaseous fluid of the circuit, and - at least one thermal pump system (An; A2) for obtaining geothermal energy stored in a fluid of a primary thermal pump circuit of a thermal pump system (An; A2), - wherein the collector circuit of the solar thermal installation (An; A1) and/or the circuit of the exhaust air thermal pump system (An; A6) with the primary thermal pump circuit of the thermal pump system (An; A2) is/are thermodynamically connected via one heat exchanger respectively to a facility which is arranged in the ground and which receives and emits thermal energy, and - the thermal energy obtained from the solar thermal installation (An;
