Life cycle greenhouse gas emissions and energy analysis of prefabricated reusable building modules

▸ Modular prefabricated steel, timber and conventional concrete buildings were compared. ▸ An eight-storey, 3943 m2 multi-residential building in Melbourne was investigated. ▸ The life cycle greenhouse gas emission and life cycle energy were quantified. ▸ The potential benefits of reusability of materials were quantified and assessed. ▸ The reductions in the space required for landfill were also quantified.
