Abstract : Energy and environmental aspects are more and more integrated in the design process of buildings. Life Cycle Assessment (LCA) is generally used to assess the environmental performance of buildings. This method uses to date a high number of data which can be a limiting aspect for its application. For instance, it can be difficult for some manufacturers to give life cycle inventory (LCI) gathering several hundreds of flows. In addition, the interpretation of the results with about ten environmental indicators can be complex for the building practitioners. In this context, the aim of this research is to study a simplified model for the LCA of buildings. A simplified life cycle inventory (LCI) database gathering building materials, products and processes is first developed. It is composed of data from the Ecoinvent and INIES database with the help of a homogeneous nomenclature. The use of statistical methods then enables to assess the relevance of simplification of the LCA model. Simplified life cycle impact assessment (LCIA) model are built between the LCI flows and the LCIA indicators. They enable previously to the applications using the database to identify the flows that are the most significant in the environmental impact of a building. The understanding of the consequences of the simplification of the LCA model and the statistical methods used in this work enable to better appreciate the reliability of simplified LCA applied to building products and buildings as a whole.
