Assessment of integrated solutions for the combined energy efficiency improvement and seismic strengthening of existing URM buildings

The European building stock is an aging infrastructure, mainly built prior to building codes. Furthermore, 65% of these buildings are located in seismic regions, which need to be both energetic and seismically retrofitted to comply with performance targets. Given this, this manuscript presents integ...
