Abstract

While traditional value engineering (VE) is primarily driven by cost saving, this study aims to comprehensively and reliably investigating the impact of traditional VE on the embodied greenhouse gas (GHG) emissions in the Australian built environment. An Australian-specific hybrid life cycle assessment (LCA) is developed and applied to a mixed-use building complex located in central Sydney, Australia. A list of GHG emissions intensities (GEIs) for 118 construction products is derived from hybrid LCA, demonstrating an average increase of 20% than the corresponding process-based GEIs. By applying the hybrid GEIs, the assessment of the case study building proves that traditional VE can potentia..
