The study presents a life-cycle analysis (LCA) of an innovative system for space conditioning. The system layout is obtained starting from a ground-source heat pump and including a thermal storage. A prototype of the system has already been implemented and it is currently in use for space heating and cooling of an industrial building. Thanks to the thermal storage, that was designed to decouple the geothermal side from the heat-pump side, the system is able to provide the required thermal energy to the building with a reduced-sized geothermal installation (i.e shorter/fewer boreholes). The performance was monitored for more than two years, both in cooling and heating modes. An LCA study of this system is presented based on specific data for implementation and operation phases. The results are given in terms of the comprehensive ReCiPe mid-point and end-point indicator suite and are compared with literature studies of other conventional technologies for space conditioning.

Abstract
The study presents a life-cycle analysis (LCA) of an innovative system for space conditioning. The system layout is obtained starting from a ground-source heat pump and including a thermal storage. A prototype of the system has already been implemented and it is currently in use for space heating and cooling of an industrial building. Thanks to the thermal storage, that was designed to decouple the geothermal side from the heat-pump side, the system is able to provide the required thermal energy to the building with a reduced-sized geothermal installation (i.e shorter/fewer boreholes). The performance was monitored for more than two years, both in cooling and heating modes. An LCA study of this system is presented based on specific data for implementation and operation phases. The results are given in terms of the comprehensive ReCiPe mid-point and end-point indicator suite and are compared with literature studies of other conventional technologies for space conditioning.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
