In the past 12 years, the United Kingdom (UK) has made significant progress in making domestic dwellings more efficient. Presently, the domestic sector is required to meet the UK’s net-zero target in new and renovated dwellings by 2050. As a measure in this on-going determination, the UK has constructed a number of Zero Energy Bill Homes (ZEBH) in Corby, Northamptonshire, which is currently a part of the European Union District of Future Project. For the effectiveness of a zero energy bill performance, a solar photovoltaic thermal-assisted heat pump (SPVTAH) was modelled, which represented building modelling, emphasising the essential outcomes through energy demand profiles (electricity, space heat, and domestic hot water), and occupant behaviour. To authenticate the building modelling, the baseline models were calibrated using the weekly electricity-use curve and validated using statistical indices. It is inferred that the evidence-based manual calibration technique has fairly validated the energy-use profiles of the chosen case studies and is found to be within acceptable tolerance levels. In addition, to verify the zero-energy bill status of the buildings, an economic analysis was extremely crucial. A feasibility assessment indicated that the ZEBH concept will be impractical if the UK government subsidies are withdrawn. Moreover, the Net Present Value analysis further signified that although SPVTAH seemingly generates revenues, the initial investment turned out to be the largest barrier to repay for the system. However, it was proven that the renewable energy technology operational in the domestic dwellings of the UK does offer major advantages, and reduction in costs appears to be the most significant one.

在过去的12年中，英国（UK）在提高民居效率方面取得了重大进展。目前，要求国内部门在2050年之前实现英国在新建和翻新住宅中实现净零目标的目标。作为这一持续进行的一项措施，英国已在科比建造了许多零能耗法案房屋（ZEBH），北安普敦郡，目前是欧盟未来项目区的一部分。为了实现零能耗法案的效果，对太阳能光伏热辅助热泵（SPVTAH）进行了建模，该模型代表了建筑模型，通过能源需求概况（电，空间热和生活热水）强调了基本成果，以及乘员行为。为了验证建筑模型，基线模型使用每周用电曲线进行校准，并使用统计指标进行验证。可以推断出，基于证据的手动校准技术已经相当有效地验证了所选案例研究的能源使用情况，并且发现在可接受的公差范围内。此外，要验证建筑物的零能耗账单状态，经济分析至关重要。可行性评估表明，如果英国政府取消补贴，ZEBH概念将不切实际。此外，净现值分析进一步表明，尽管SPVTAH似乎产生了收入，但最初的投资却成为最大的偿还系统的障碍。然而，
