The INFINITE Building Renovation project, funded by the European Union’s Horizon 2020 research and innovation programme, presents the case study of the Italian sister buildings. These two multifamily residential buildings were constructed in 1978 and 1979, each comprising four residential units.

The INFINITE study focuses on comparing energy performance before and after the renovation of these dwellings. This is possible due to the fact that they are twin buildings.

INFINITE’s renovation strategy incorporates Building-Integrated Photovoltaics (BIPV), Building-Integrated Solar Thermal (BIST), smart glasswork, energy and fresh air distribution, adaptable Building Management Systems (BMS), and a BIM platform providing users with tailored solutions. 

In this specific case, the façades facing south and east will accommodate BIPV modules, while passive solutions will be implemented on the north and west façades, with potential for ecological integration. Smart windows will feature a system capable of assessing the impact on indoor comfort and energy consumption. Additionally, an advanced air distribution kit will be tested, providing fresh air, heating, and cooling.

This case study exemplifies INFINITE’s commitment to industrialised renovation, offering replicable solutions for improving building energy efficiency. The project seeks to optimise renovation processes and minimise environmental impact across Europe through the integration of digital modelling, prefabrication, and smart energy systems.
