Criteri di smontaggio e riciclaggio di componenti edilizi nei progetti di recupero e di nuova progettazione modulare. Qualità architettonica ed edilizia per costruzioni sostenibili.

When an architectural design is defined as sustainable, whether for new construction or renovation design, it is assumed that its design follows those criteria that allow it to meet the required performance without compromising the future possibilities of maintenance and useful life of the building. Environmental impact, economic and sociological analysis are primary factors in assessing the sustainability of an architectural project. Conceived from this perspective, the process needs a finely tuned approach, especially for technical evaluations, such as the choice of materials and components, as well as architectural and building quality. For refurbishment projects, where the total cost is difficult to determine initially, it appears necessary to develop a conservative practice that includes the possibility of reusing and recycling materials recovered from the same building as well as from others. Such an approach defines, with elastic criteria, the possibility to work with historically consolidated elements allowing to solve effectively the problems of cost and of materials and elements. In fact, restoration often puts the designer in the condition of operating on buildings of particular architectural value, enriched with finishing elements built with materials that are not easily available, and with traditional techniques that are not easily reproduced, considerably increasing the costs of the project. Similarly, for new constructions, modular technology makes it possible to create building systems that can be assembled and subsequently dismantled to be built on different sites, finding particular utility, for example, in interventions immediately following an earthquake.
