Evaluation of benefits for integrated seismic and energy retrofitting for the existing buildings

Currently, a significant part of the residential building stock has been built without modern provisions for earthquake resistance and energy efficiency, resulting in high seismic vulnerability and very expensive management and environmental cost due to low energy performance buildings. An integrated approach to seismic and energy retrofitting is need to reduce the effects seismic events and energy consumption. In this work, the economic effects of the seismic events are evaluated for existing Reinforced Concrete buildings are considered. The energy performances of buildings are also evaluated. Then based on an integrated approach, the seismic and energetic Expected Annual Loss is evaluated. It is obtained combining both the cost of the seismic risk consequence and energy cost. Finally, the economic feasibility is based on the global Economic Feasibility Index
