Life-cycle assessment of light steel frame buildings : A systematic literature review.

Light Steel Frame structures (LSF) have become one of the main competitors of traditional construction systems. The optimized material use, its lightness, and the timesaving in the construction phase, show the potential of this technology to reduce environmental impacts. The purpose of this study is to review and analyse the current literature on the application of the Life Cycle Assessment (LCA) methodology to LSF buildings and identify related gaps. A systematic literature review has been performed to query Web of Science and Scopus databases, highlighting methods, limitations, trends, and tools used to address LCA applied to LSF buildings. Although many efforts have been made to evaluate LSF buildings in comparison with other construction solutions, a gap persists in performing whole LCA. Considering the potential disassembly and reuse offered by LSF and the recyclability of steel, there is a need for future research focusing beyond the end-of-life stage.
