The A Fighera case articulates an integrated approach to energy efficiency in collective housing, combining an optimised building envelope, intelligent management and renewable energy sources.
The A Fighera building, a new build completed in 2024 as a collective residential development, represents a rigorous technical exercise aimed at maximising energy efficiency within a demanding urban context. With significantly reduced primary energy consumption, the project not only meets but exceeds minimum regulatory requirements through the achievement of demanding certifications: E3 level under the E + C- framework and three stars under the OTIMU label, both recognising reduced consumption and the effective integration of renewable energy.
The energy concept brings together a mix of renewable sources, including roof-integrated photovoltaic panels and a connection to Monaco’s thalassothermal network, which supplies up to 65% renewable energy for heating and cooling. The building envelope and a dual-flow ventilation system with heat recovery minimise thermal losses, while an advanced energy management system optimises the operation of these technologies. In addition, a hydrogen-based storage system is being explored to capture photovoltaic surplus and supply common areas, reinforcing energy resilience and supply stability.
A Fighera’s design logic is grounded in the early integration of efficiency measures and renewables, supported by passive strategies and intelligent management. This approach has demonstrated measurable reductions in energy use and emissions, while offering a replicable model for residential developments in dense urban areas seeking to meet sustainability and energy transition objectives.
