A framework for the evaluation of the decision between onsite and offsite construction using life cycle analysis (LCA) concepts and system dynamics modeling

The decision to choose between onsite and offsite construction is important in the effort toward sustainable construction. Offsite often promoted as an environmentally friendly approach operations. However, previous studies have shown that there a lack of clarity on environmental trade-offs Factors can affect build or include availability local manufacturing facility, distance factory final place use, proximity site supply material labor, etc. This study provides framework apply system dynamic modeling technique evaluate how various factors impact building phase (for methods). model (using Vensim software) was developed platform allows users input variables such expected for transportation material, equipment both facility location, associated with use construction, needed panels modules from site, Among other things, showed increase yard increases total impacts completed modules. An number trips location In terms none two methods gives absolute superiority over other. performance depends factors. It recommended practitioners review are peculiar their projects make informed best methods.
