Environmental sustainability of off-site manufacturing: a literature review

Abstract

Purpose

Off-site manufacturing (OSM) is a modern method of construction that brings various environmental sustainability benefits for stakeholders. The increasing take-up of OSM in practice has attracted much research interest in its environmental sustainability. However, a holistic understanding of these previous research studies is still lacking. Therefore, the purpose of this paper is to critically review the existing body of knowledge regarding the environmental sustainability of OSM.

Design/methodology/approach

A qualitative content analysis was adopted to systematically and objectively review 55 related historical studies.

Findings

Three research themes were identified, including environmental sustainability assessment and performance, environmental sustainability strategies and critical environmental sustainability factors. A detailed discussion of the three themes was conducted to depict a whole picture of the current explorations in the research field. Additionally, a research framework was developed to articulate the interrelationship between the research themes and their specific research topics. Scientific research gaps were identified together with the future research directions in terms of sustainability strategies, performance impacting factors, sustainability indicators and drawbacks resulted from OSM application.

Originality/value

The literature review promotes construction stakeholders’ in-depth understanding about the environmental sustainability of OSM, which offers valuable implications for green industry practice. Additionally, it highlights the future research trends, which facilitates further explorations in the research area.
