“…Case studies and LCA frameworks (that could be operationalised) were separated for detailed analysis, numbering 42 documents in total [1, 2, . The remaining 24 documents [5,13,15,19,21,[62][63][64][65][66][67][68][69][70][71][72][73][74][75][76][77][78][79][80] were included in the literature review, in addition to 12 academic articles, industry documents and reports [9,[16][17][18][81][82][83][84][85][86][87][88] that were selected using a backward and forward snowball approach (papers from the reference list, and papers that cited articles in the review). This technique was used when there were perceived information gaps.…”

Buildings and construction are among the leading contributors towards global greenhouse gas emissions, resource demands, waste, and pollution, placing a massive strain on our natural environment. Until recently, mitigation strategies have primarily concentrated on reductions in operational energy, failing to account for embodied effects; those associated with the manufacture of construction goods, construction activities, and end of life considerations. In recent years, there has been an increased recognition of the growing significance of embodied effects, and the opportunity to reduce these during the building design process. However, life cycle assessment (LCA) tools used to quantify environmental flows are often perceived as being too time-consuming or complicated to incorporate into prevalent building design workflows. The aim of this study was to review approaches for assessing embodied environmental effects during the building design process, including the LCA tools and environmental data used to achieve this. A systematic review was conducted of academic and grey literature. The study identified three main approaches for incorporating LCA into the building design process: simplified LCA, detailed LCA and incremental LCA. Further analysis of these approaches was conducted, based on case studies. General attributes and design considerations were identified, and mapped against the early design, and detailed design stages. A wide variety of LCA approaches were reviewed, responding to various challenges for incorporating LCA into the building design process, with no singular approach able to completely satisfy all requirements. Findings highlight the lack of incremental LCA approaches, and the need for further research to understand how LCA approaches can be better used to improve the embodied environmental performance of buildings during the design process.
