Energy-efficient renovation of existing buildings has become a key driver in meeting Europe’s climate targets. Supported by the European Union, the REHOUSE renovation project introduces a suite of advanced technological solutions to improve the energy performance of the current building stock, which accounts for a significant share of global CO₂ emissions.

Among the innovations developed are multisource heat pumps, adaptable dynamic envelopes, smart façades, and high-performance windows, all designed for integration into modular, sustainable, and replicable renovation processes. These technologies are being tested in pilot buildings located in France, Greece, Italy, and Hungary, enabling the assessment of their real-world impact under diverse conditions.

In addition to its technical developments, the project incorporates a comprehensive monitoring system to track key performance indicators (KPIs) related to energy consumption, indoor comfort, and environmental sustainability.

By combining recycled materials, prefabricated solutions, and bioclimatic design strategies, REHOUSE significantly reduces energy demand without compromising building aesthetics or liveability. The project do not only delivers practical tools for large-scale renovation but also drives meaningful reductions in energy use through scientifically validated technologies.
