The ecodesign methodologies to achieve buildings’ deconstruction: A review and framework

The ecodesign methodologies in the design stage enable buildings to be adapted to the needs of users and deconstructed at the end-of-life. Although ecodesign methods incorporate circular economy (CE) principles, they are little explored in projects and constructions. This study analyses how the construction sector approaches ecodesign methods to achieve buildings' deconstruction. Through an integrative literature review, 288 articles were threefold analyzed: (i) bibliometric, (ii) conceptually about ecodesign methods, and (iii) categorically. The results showed a lack of understanding about the ecodesign concepts, and an integrated methodology was proposed. The most inclusive and sustainable ecodesign method for buildings deconstruction was Design for Adaptability and Disassembly (DfAD). The review shows the concentration of the studies in three categories and a framework was created relating DfAD strategies. The sector needs more information on ecodesign methods, deconstruction strategies, reusing of materials, and in the life cycle tools as decision support to make sustainable buildings.
