Comparative study of the life cycle embodied greenhouse gas emissions of panelised prefabricated residential walling systems in Australia

Abstract

Residential buildings account for 17% of global greenhouse gas (GHG) emissions. With detached housing accounting for over 70% of all of Australia’s residential dwellings, and a projected doubling of population in the next 40 years, these houses represent a significant opportunity for GHG emissions reduction. Prefabrication can improve the environmental performance of buildings through lower resource input, reduction in waste and improved quality. However, little research exists on whether it reduces embodied GHG emissions, an increasingly significant proportion of a building’s life cycle GHG emissions. The aim of this study was to compare the embodied GHG emissions associated with the constr..
