Building-integrated photovoltaics (BIPV) is widely adopted to achieve the EU's green transition goal. However, the efficiency of most BIPV systems is limited as they primarily utilise the rooftop space of buildings. 

Using both the rooftop and facade surfaces of buildings can improve the surface utilization of BIPV systems. Still, it also poses new challenges, including the heterogeneity and incompleteness of sensor data for semantic 3D reconstruction of buildings, various unstable factors affecting BIPV design and layout, and the necessity to coordinate and integrate BIPV systems with other energy systems. 

This project aims to develop a Semantic 3D Energy Model (S3EM) for BIPV systems, which leverages multi-modal data to construct accurate 3D representations of solar radiation and electrical potential across building surfaces, enabling the optimal placement of BIPV components and their smooth integration with other energy systems.

Start date: February 2025 - End date: February 2027
