“…Its function is to make sure that buildings can receive the appropriate sunlight in the various seasons, and the system has been installed at Tecnalia shown in Figure 13. The results show that after using this system, compared to the other system, the production of photovoltaic power increases from 10% to 20% in spring and summer [18]. The latent heat storage of the phase change material (PCM) is beneficial for thermal energy storage (TES) in solar energy systems.…”

It has been proposed in China that the country should reach a “carbon peak” by 2030 and be “carbon neutral” by 2060. In the context of energy conservation and emission reduction, the country’s energy structure needs to be transformed to improve the technology level and more widespread consumption of renewable energy. The global renewable energy utilization situation is first analyzed in this study from the perspective of renewable energy and the buildings using it, highlighting the importance of the application of renewable energy in buildings. Secondly, from the perspective of solar energy utilization technology, ground source heat pump technology, and systems for managing energy use in buildings, the progressiveness of renewable energy applications in buildings is analyzed. The application of these technologies in buildings is demonstrated from various angles. Thirdly, the development prospect of buildings using renewable energy is discussed from the perspective of the promotion of renewable energy-powered buildings and green construction. The development prospects of buildings using renewable energy are discussed from the economic benefits of green finance, the promotion and social support of renewable energy, and the environmental benefits of green buildings. Finally, based on studies in the United States, the United Kingdom, Russia, and China, the international energy policy and development direction, as well as the evaluation criteria of green buildings, are discussed, along with an assessment system for green buildings that is complementary to the strategic agreement.

Based on the available literature, the status and prospects for further development of the building integrated photovoltaics (BIPV) market were analyzed. The results of the analysis show that the high investment costs and the lack of information about installed BIPV systems and BIPV technology are a problem for the stakeholders. BIPV technology is an interdisciplinary problem, so the cooperation of a large number of different experts is important. However, it is not yet at a satisfactory level. Another problem is the overlapping of responsibilities of HVAC installers, interior designers and facade manufacturers. On the other hand, the incentives of the EU regulatory framework and beyond to use renewable energy sources in both new buildings and renovation of old buildings, as well as the desire for energy independence, encourage the application of BIPV technology. An analysis of the electricity production potential of BIPV integrated into the walls and roof of the building was made for four geographical locations. A comparison of the production of electricity on the walls and on the roof of the building was carried out. The analysis shows that on the 4 walls of the building, where each wall has the same area as the roof of the building, approximately 2.5 times more electricity than on the roof can be generated. In the absence of available surface for installing a PV power plant on the roof, the walls represent a great potential for BIPV technology.

“…By enhancing the power output of solar installations without the need for additional land, bifacial PV systems contribute to a more efficient use of resources. This efficiency is not confined to optimal conditions; bifacial modules demonstrate resilience in a variety of environmental settings [11,12], including regions with lower solar irradiance and urban landscapes [13] where space and light conditions are constrained.…”

This paper presents the first comprehensive study of a groundbreaking Vertically Mounted Bifacial Photovoltaic (VBPV) system, marking a significant innovation in solar energy technology. The VBPV system, characterized by its vertical orientation and the use of high-efficiency Heterojunction (HJT) cells, introduces a novel concept diverging from traditional solar panel installations. Our empirical research, conducted over a full year at the University of York, UK, offers an inaugural assessment of this pioneering technology. The study reveals that the VBPV system significantly outperforms both a vertically mounted monofacial PV (VMPV) system and a conventional tilted monofacial PV (TMPV) system in energy output. Key findings include a daily power output increase of 7.12% and 10.12% over the VMPV system and an impressive 26.91% and 22.88% enhancement over the TMPV system during early morning and late afternoon hours, respectively. Seasonal analysis shows average power gains of 11.42% in spring, 8.13% in summer, 10.94% in autumn, and 12.45% in winter compared to the VMPV system. Against the TMPV system, these gains are even more substantial, peaking at 24.52% in winter. These results underscore the VBPV system's exceptional efficiency in harnessing solar energy across varied environmental conditions, establishing it as a promising and sustainable solution in solar energy technology.
