The study applies the proposed concept to a multi-family building in the province of Milan. The analysis relies on dynamic energy simulations of the building and thermohydraulic simulations of the low-temperature distribution circuit. Energy, economic, and environmental indicators are evaluated to compare the proposed solution against a benchmark retrofit with individual condensing gas boilers. The study demonstrates that the proposed renovation concept leads to increased Energy Efficiency Class compared to the benchmark renovation scenario, as well as to lower operating costs and CO2 emissions. The proposed concept is promising, especially for areas where groundwater is easily available, and no local legal restrictions are present. Pages: 273 - 280 Paper:
