Amélioration de la fiabilité des évaluations environnementales des bâtiments

Abstract : The work of this thesis focused on the improvement of the reliability of environmental assessments of buildings by a better control of the origin and amplitude of uncertainties. This thesis has permitted:-The development of a methodology for evaluating the uncertainties in the LCA of building;-The construction and enrichment of a database capitalizing uncertainties in material and product scale used in support of the assessment of building's uncertainties;-Development of a contribution and sensitivity analysis, which allowed the identification of key parameters influencing on the LCA results and in the robustness of study;-The development of a methodology for robust comparisons of projects based on contribution analysis and sensitivity analysis.-Identification of optimal environmental dimensions of reinforcing concrete structures. This study also identified the evolution of environmental impacts on function of building's dimensions. The methodologies used are suitable to developers of LCA software to enhance the functionality of using comparisons of projects (this work can be implemented in the ELODIE software).The results can be used by architects, civil engineers, thermal engineers, statisticians, environment and life cycle Engineers, enabling the identification of the most impacting contributors and those influencing most the outcome's uncertainties
