Optimization of Synergetic Seismic and Energy Retrofitting Based on Timber Beams and Bio-Based Infill Panels: Application to an Existing Masonry Building in Switzerland

This paper presents an optimization process for the design of a novel synergetic seismic and energy retrofitting strategy that combines favorable mechanical properties timber attractive thermal insulation bio-based materials. The method, defined as Strong Thermal Seismic Backs (STSB), comprises attachment frames panels on vertical envelope facade walls existing masonry buildings, thus improving both behavior performance these buildings. is integrated visualized in framework holistic evaluation behavior, carbon footprint Energy Retrofitting Scoreboard (SERS). benefit quantified based numerical simulation unreinforced building located Switzerland, assessment proposed retrofit solution. Three alternatives are investigated building, comprising beams two different materials building: cork recycled natural grass. optimal among assessed this study chosen Multi-Criteria Decision Making (MCDM) procedure.
