Abstract
The practice of reusing building components, today, turns out to be more complex than in the past, as industrial production, in order to meet increasingly high-performance design require ments, has generated a multiplicity of composite products, which are difficult to separate, to meet contemporary different requirements. On the other hand, the current design-build supply chain is still traditional in nature, being anchored to a linear type of dynamic, where it does not provide for an interface between the operators placed at the ends of the process: designer and demolition company. International (LEED, DGNB, BREEAM, etc.) and italian (CAM) sustainability certifi cations impose purely quantitative references, for determining the incidence of disassembly of buildings. This approach, however, turns out to be realistically biased as it does not investigate the qualitative aspects of the building itself, in terms of technological characteristics and types of constraint of technical elements. The methodological approach is therefore aimed at providing a qualitative-quantitative tool that can objectively assess the disassembly factor of the steel build ing. The aim is to lay the groundwork for the drafting of a shared protocol that can in some way smooth out the critical issues and obstacles that, at present, discourage the practice of reusing structural steel.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
