A proposal of ecological indicators for assessing the disassemblability category in the sustainability of civil construction designs

This study aims to conduct a quantitative analysis of the environmental impact of reusable elements and demountable construction systems applied in buildings according to the Design for Disassembly (DforD) strategy. The construction industry is a main resource consumption and a significant contributor to greenhouse gas emissions. In this context, the demand in the literature for more sustainable and circular construction systems stands out, as the environmental and societal impacts caused by the construction industry are substantial.This paper proposes the inclusion of ecologicall indicators into the DforD methodology, with a particular focus on steel constructions, which present great reuse potential. In addition to proposing an environmental scoring system for the DforD strategy, this study discusses circular design, lean construction, and sustainable construction in the Brazilian construction industry scenario. The analysis of the applicability of DforD with the proposed ecological indicators in the Brazilian context is crucial for fostering public works projects aligned with reuse principles. Therefore, the DforD scoring system proves to be a promising approach to promoting the circular economy in the construction industry, allowing the reduction of the number of stalled public works projects and promoting leaner and more sustainable construction practices.
