Impact of the lifespan of building external walls on depletion of natural resources

The paper focuses on the assessment of natural resources consumed by the walls of buildings according to their lifespan. These assessments take account of the construction, maintenance and end of life. In the first part of the paper, the methodology is described, finally modeling the evolution of these indicators with time. In the second part, since the lifespan of a product is very difficult to determine objectively, it is considered as a variable. The numerical results presented point out the need to revisit the current life cycle tools.
