Abstract :
[en] Methodologies based on Life Cycle Assesment (L.C.A) give the opportunity to realise a global and complete evaluation of the environmental effects of products from their production to their use and elimination (from craddle to grave); methods used for analysis are internationally wellknown and standardised. These methods are rarely used in construction materials area, although materials flows and energy consumption are important and constructions have a long way of life. A calculation methodology, based on ecofactors/ecopoints, has been used for the analysis of industrial hall made of concrete, steel, or concrete/wood structure; materials but also construction process are compared at the point of view of their environmental impact. This analysis completes the technical and economical approaches for the construction owner and designer and gives a global view of the interaction between construction and civil engineering, and environment.
