Scientific Reports 14, Article number: 923 (2024) Cite this article In order to reduce the energy consumption of buildings, an air source heat pump assisted rooftop photovoltaic-thermal integration system is designed. The installation area of photovoltaic modules and collectors will not only affect the power side, but also affect the thermal side.
We found combining appropriate insulation with PV can provide a cost-effective option to reduce net primary energy use in residential buildings. Savings from insulation alone varied from 3% (apartment complex) to 17% (single-family).
In recent years, the global push for renewable energy has highlighted the importance of photovoltaic (PV) roofs, which generate on-site electricity and reduce building energy consumption [, , ]. However, PV installations also contribute to localized heating, known as the Photovoltaic Heat Island (PVHI) effect .
Combined with the characteristics of high-rise buildings, the introduction of roof photovoltaic photo-voltaic heat integration system into the energy-saving construction of high-rise buildings is of great significance in reducing energy consumption, promoting the application of green new energy and constructing green low-carbon buildings 10.
