ABSTRACT
Stakeholders in the building sector are becoming increasingly aware of the challenges of sustainable construction. In addition, the application of tools such as life cycle assessment (LCA) to the eco-design process makes it possible to integrate an environmental dimension within the decision-making process. However, the decision-makers’ choices are still rarely justified by the environmental consequences of the building or district variants being studied. One of the disincentives that can account for this phenomenon is the lack of confidence due to the potential effects of uncertainties on LCA results. An approach for quantifying the uncertainties of LCAs for buildings is presented in this chapter. The aim is to study the robustness of LCA results with respect to these uncertainties, and to progress towards more reliable LCA tools.
