Researchers from the University of Ljubljana in Slovenia have developed an innovative model to calculate energy flows in green roofs equipped with photovoltaic systems. Green roofs, covered with vegetation, can contribute to cooling solar panels, thereby increasing their efficiency.
The research team validated their model by testing it on a real setup. The aim of the study is to accurately determine all heat flows and improve evapotranspiration calculations, which are crucial for predicting water consumption. This approach ensures that the findings are not only useful for further research but also for industry experts looking to implement energy-efficient urban infrastructure solutions.
Using simplified 2D view factor and advanced 3D approaches, the researchers calculated energy flows in green roofs with integrated solar systems. They also found that, without using the detailed model, the evapotranspiration rate would be underestimated by 18%.
This study represents a significant step in understanding the impact of integrating solar panels with green roofs on energy efficiency and water management. Accurate heat flow calculations enable better water consumption predictions, contributing to the development of sustainable urban infrastructure.
