The global challenges of rising energy consumption and carbon emissions underscore the urgent need for efficient sustainable heating solutions in building sector. implementation high-performance buildings that envelope insulation increasing adoption low-temperature radiant systems have significantly reduced water temperature required from heat sources, enabling greater compatibility with renewable systems. In this study, we propose a system incorporating solar-assisted medium-depth ground exchanger (MDGHE). A dynamic simulation model MDGHE was developed TRNSYS, featuring novel module specifically to improve accuracy. case study residential China conducted evaluate performance proposed system. results demonstrate while standalone covers 71.9% building’s demand, integrating solar collectors can increase coverage 99.9%, full compliance requirements without relying on conventional pumps. revealed system’s COP reached 9.26. Compared traditional source pump 4.84, efficiency has been enhanced by 47.7%. static payback period 7 years obtained compared cost central service buildings. These findings highlight potential solar-geothermal hybrid as alternative methods.
