Energy retrorofit of residential buildings with a novel super-insulating aerogel-based plaster

The interest on superinsulation materials is growing, as particularly suitable in energy retrofit interventions due to the possibility to achieve relevant improvements even when used in low thickness. In this field, a specific EU funded H2020 project, named Wall-ACE, was carried out in the last three years, connecting products manufacturers, researchers and buildings owners, with the common goal of developing and testing a set of new aerogel based insulating products to be used in new and existing buildings. The study here presented reports the results of the research activity developed by the Authors on a novel aerogel based internal plaster. Firstly a set of analysis at material level was carried out to identify the most eff ective mixture able to achieve the target value of thermal conductivity <0.03 W/mK. Then the application on a demonstration building allowed evaluating the actual thermal resistance achievable under real operating conditions. Finally, simulations at building scale were performed to determine the energy-saving potential of this retrofit tecnique.
