Lifespan prediction of existing building typologies

Life-cycle assessment (LCA) is currently one of the construction industry's most widely used methods environmental assessment. Because LCA calculations based on life-cycle thinking are lifespan building a sensitive parameter in relation to calculated overall impact building. More accurate assessments lifespans buildings therefore prerequisite for reducing errors and uncertainties Life Cycle Costing (LCC) calculations. This study evaluates generalized logistic prediction model existing typologies. The tested as part Danish case data collected from 124,096 cases demolition. objective investigate whether typical or LCC accurately describes remaining service life different typologies periods. show that office generally have much shorter expected than previously assumed multi-family housing has nearly twice single-family housing. results tendency declining period, which newer buildings, i.e. those no more thirty years old, average all These highly relevant both since they indicate northern Europe lower previous studies shown.
