This study investigates the potential of contemporary Earth-Sheltered Buildings to contribute to sustainable societies by achieving Plus Energy Building status during the heating season. The buildings analyzed are intended to house a four-member family (102.5 m²). The house is equipped with a ground source heat pump, geothermal vertical probes, floor heating panels, an energy recovery ventilator, and building-integrated photovoltaic panels installed on the exposed building wall. The numerical analysis (using EnergyPlus software) was carried out for nine European sites covering five different climatic zones (namely: southern, Atlantic, continental, alpine, and northern climate) and three latitude belts spanning Europe from south to north. Buildings above 65° N (northern and alpine climate) could not achieve Plus Energy status with 20% efficient BIPVs. With 15% efficient BIPVs, the building above 59° N (northern climate) was incapable of achieving this as well. Regarding the monthly time step, the buildings in the southern and Atlantic climates with 15% efficient BIPVs were able to produce an energy surplus every month, as was the building in the Alps with 20% efficient BIPVs.

这项研究调查了当代地球庇护建筑通过在供暖季节实现加能源建筑地位来为可持续社会做出贡献的潜力。分析的建筑物旨在容纳一个四口之家（102.5 m ²）。房屋配备了地源热泵、地热垂直探头、地暖板、能量回收通风机以及安装在裸露建筑墙上的建筑一体化光伏板。数值分析（使用EnergyPlus软件）针对覆盖五个不同气候带（即：南部气候、大西洋气候、大陆性气候、高山气候和北部气候）以及横跨欧洲从南到北的三个纬度带的九个欧洲地点进行。北纬 65° 以上（北方和高山气候）的建筑物无法使用 20% 高效 BIPV 达到 Plus Energy 状态。对于 15% 效率的 BIPV，北纬 59° 以上（北方气候）的建筑也无法实现这一目标。关于每月的时间步长，
