Components reuse in the building sector - A systematic review

Area of Science:

• Construction Management
• Sustainable Building
• Circular Economy

Background:

• Building component reuse is crucial for material circularity in the construction sector.
• Current reuse practices are not widespread, despite existing research on influencing factors.
• A comprehensive harmonization of factors affecting building component reuse is lacking.

Purpose of the Study:

• To systematically identify and stratify factors influencing the reuse of superstructure building components.
• To delineate correlations and inter-dependencies between these identified factors.
• To provide insights for promoting mainstream adoption of building component reuse.

Main Methods:

• Systematic literature review of peer-reviewed journal articles.
• Classification of identified factors into six major categories and 23 sub-categories.
• Development of correlation indices to study inter-dependencies between barriers.

Main Results:

• Factors affecting building component reuse are categorized into six main groups and 23 sub-categories.
• Economic, social, and regulatory barriers require prioritization for effective intervention.
• The highest inter-dependency exists between perception and risk factors, indicating perception is influenced by associated risks.

Conclusions:

• Addressing economic, social, and regulatory barriers is critical for advancing building component reuse.
• The strong link between perception and risk suggests that mitigating perceived risks can improve stakeholder acceptance.
• This research provides a framework for understanding and overcoming barriers to widespread building component reuse.
