The environmental impact of prefabricated renovation systems: a worthy alternative to on-site renovation?

Abstract The conventional renovation practices, which are mainly characterized by time-consuming manual on-site techniques, partly contribute to the low rate. Accordingly, a faster and more efficient approach is necessary. implementation of prefabricated systems could offer possible solution. These increasingly being studied, but little known about their environmental impact. Hence, this study investigates impact means Life Cycle Assessment (LCA) two façade timber frame sandwich panel; compares it well-known technique, External Thermal Insulation Composite System (ETICS). First, reference designs assembled. Subsequently, different life cycle stages determined in order clearly indicate differences between systems. More specifically, production, transport, replacement end-of-life stage assessed. In end, examined over time combining all stages. results show that not yet worthy ecological opponent ETICS. As production stage, appears be higher. Optimising through an extensive redesign lead competitive or even favourable terms
