The project aims to develop, optimize, and test a lightweight PV modular façade element for application on the s building’s external walls. The ActiVer system’s advantage lies in its integration of PV with a passive heat dissipation system, along with its lightweight and fully prefabricated design. The system will undergo comprehensive experimental and computational testing covering its physical behaviour (heat and mass transfer), energy performance and management (including heat dissipation), environmental performance (Life Cycle Assessment and Carbon Footprint analyses), and cost-effectiveness (in close cooperation with industrial partner), considering the needs of the stakeholders, effects and potential impacts on the environment and society (RRI actions).
