Reversible, Sustainable and Circular Constructive Systems: Buildability Conditions

The paper reports the results of an investigation of the Reversible Technologies oriented to solve the problem of the huge quantity of building components that once disassembled have still residual performances. Thus, using Reversible Technologies, it is possible to reach the extension of the use of constructive systems, activate the potential circularity of the disassembled systems and obtain the environmental impacts optimization of the buildings, demonstrated by the analysis of LCA studies taken from literature. In practice, the potentialities of the reversibility are not always exploited, due to the lack of effective reversible products on the market and competent operators. To face it, the research aimed to define the Buildability Conditions on technical and operative levels, for the actualization of reversible technologies and the activation of circular solutions. Thanks to the design and manufacturing practices (Pre-conditions) that generate the reversible transition in the construction sector, the Buildability Conditions are applicable. Specifically, the conditions defined are the operative actions (Soft Conditions), regarding the actions to develop by the operators involved and the definition of tools and methods, that support the development and verification of the technical characteristics (Hard Conditions) of the constructive systems. The next step of the research will be the application of the Buildability Conditions on practical experiences, to verify their feasibility and actual contribution.
