Abstract

Purpose

Design for adaptability and disassembly (DfAD) is an effective method to reduce construction and demolition waste generation, landfill loads and greenhouse gas generation; preserve natural resources; and increase environmental awareness in the construction industry. However, it is an underexplored strategy due to a lack of information about projects and a set of agreed guidelines to guide buildings deconstruction. This study aims to understand how DfAD can support the sector’s transition toward circularity.

Design/methodology/approach

Through an integrative literature review, this study analyzed the current publications and terminologies used, identified the main themes discussed and described the key criteria for integrating deconstruction in the building design stage.

Findings

The results showed that the term DfAD encompasses different ecodesign strategies and is concentrated in six major thematic categories (design and construction principles, tools for DfAD, components and connections for DfAD, barriers, drivers and guidelines for DfAD, existing building stock potential and selective deconstruction process). In total, 60 criteria were presented to guide the deconstruction of buildings, emphasizing standardization, modularization and prefabrication of materials and components as fundamental requirements.

Originality/value

The study highlighted the need to expand the knowledge and training of the design team, establish public policies and tax incentives and develop tools, methods, and circular indicators to enable the implementation of deconstruction strategies for buildings.

Abstract

Purpose

Reuse and recycling building materials depend on an efficient set of information and tracking, which can be obtained by the materials passport (MP) tool. Although MP introduces principles of circular economy (CE) and brings environmental, social and economic benefits, it is little-explored in the construction sector. The purpose of this study is to explore the adoption of the MP in the sector to raise awareness about this tool. This analysis leads to the conception of a model and identifies the main challenges and opportunities to increase MP implementation in the sector.

Design/methodology/approach

Through a systematic literature review, based on the descriptive and thematic analysis, articles were selected, and analyzed to (1) review the MP state-of-the-art in the construction sector; (2) propose a materials passport model and (3) list the main challenges and opportunities to MP adoption.

Findings

The studies about MP were concentrated on strategies to implement general concepts and business opportunities. The MP model was proposed to overcome the lack of studies and understanding showed in the review. The model aimed to improve the recovery and reuse of materials across a building's life cycle. Challenges and opportunities were raised to direct decision-makers and support the development of this tool. A systematic regulation in the construction value chain and policy systems is crucial for creating digital platforms for data management of buildings' material.

Originality/value

This study developed an MP model to enable the management of building materials at different stages of the building's life cycle and contributes to future developments of the studies on this knowledge domain.
