Resumen
This research is an attempt to describe a new biomimetic model for the rehabilitation of social housing. In particular, the constructions built in Europe in the post Second World War period suffer of material and social degradation requiring architectural, functional and structural interventions. The analysis of the state of the art underlined the importance of the envelope in the definition of new performances and standards. Through a bio-mimicry approach, the paper shows the process leading to the definition of a building exoskeleton: a structural envelope able to solve complex sets of problems integrating different building systems. Adaptability results being a fundamental property to define an effective seismic and structural behavior but also to respond to changing user?s needs and environmental conditions. In the last part of the paper, information about feasible technologies and techniques to realize the exoskeleton are presented. Finally, the conclusions show the potentiality of the model if applied in critical contexts where intensive and diffusive interventions of recovery of social housing are needed.
