A BIM-enabled Estimating Framework of Embodied Emissions of Building Materials for Optimization in Design Stage: A Case Study

Abstract

The GHG emissions from the life cycle of building construction have been regarded as one of the major contributors to environment impact. The numerous usage of construction materials also involves high embodied GHG emissions. The pressure of global warming requires construction firms to take various actions to cut down GHG emissions from every stage. To select low carbon building materials in design stage is an effective measure. This paper presents a new decision-making tool integrating the Building Information Modeling (BIM) and GHG emission analysis tool, which can calculate the embodied emissions of building materials. This tool can provide an accurate calculation of embodied carbon emissions in design stage, which is valuable for decision-maker to optimize the selection of low carbon materials for their projects. This research has shown that BIM.
