A comparative study between a Prefab building and a Standard building for the characterisation of production and construction stages

The reduction of heterogeneous systems in a prefabricated house can make improvements both in terms of less environmental impacts and higher efficiency in the construction stage. The aim is to point out the main environmental advantages of a prefabricated building in comparison to a standard building with similar features, in the first two stages of their life cycle: production and construction. The paper also deals with the reuse, recovery and recycling potential of the two buildings in order to determine if the use of only dry construction systems have a positive effect in a future end of life scenario. The results show a better performance of the prefabricated building if compared with the standard building in terms of Global Warming Potential, Embodied Energy and Human Toxicity Potential.
