Uncertainty and Sensitivity Analyses for Evaluating the Building Element‘s Replacement in Building LCA

Abstract

This paper presents a systematic way to consider the uncertainties of the building elements‘service lives within a stochastic framework, by defining the corresponding probability density functions, based on a service life database. This methodology is appropriate for screening and detailed building LCA, since the service life database offers the possibility to define the probability density functions of the service lives, in different level of details
