Analyzing the Environmental, Economic, and Social Sustainability of Prefabricated Components: Modeling and Case Study
The building industry has significant environmental, economic, and social impacts. The trend of construction industrialization to promote sustainable development is becoming increasingly evident. As an essential component of this process, prefabricated components provide a foundation for studying the sustainability of prefabricated buildings. This study proposes a life cycle sustainability assessment (LCSA) model involving environmental, economic, and social aspects to assess the sustainability of prefabricated components. The sustainability impacts on the raw material extraction and production, off-plant transport, material processing and component manufacturing, on-plant transport, and component storage stages are comprehensively assessed. The LCSA model is applied to four types of prefabricated components: interior wallboards, precast stairs, composite beams, and composite floor slabs. The results show that the precast stairs exhibit the highest sustainability score and that the performances of environmental, economic, and social pillars of four components are slightly different. These findings enhance our understanding of the sustainability of prefabricated components and broaden the scope of LCSA applications. The established sustainability assessment model is expected to help guide prefabrication scheme designs and production plan optimization, further encouraging the wider adoption of sustainable practices in construction.
