Abstract

This chapter reports the synthesis of the results obtained by the research unit “Durability of Building Components” of the BEST (Building Environmental Science and Technology) department of Politecnico di Milano, with a particular attention on the “Methodological development for design and evaluation of durability of building components: experimental evaluation of durability of external self-supporting walls” The chapter synthesizes and updates the results reported in the book: “. La valutazione della durabilità di pareti perimetrali verticali non portanti. The durability evaluation for external self-supporting walls” (ed. EdiTecnica, Palermo, 2006) published in the conference “La Qualitá Tecnologica Edilizia. La Valutazione della Durabilitá dei Componenti Edilizi. The Building Technological Quality. The Building Components Durability Evaluation. “ which took place in Palermo in September 2006. The activity carried out by the research unit of Milan was, in general, about the definition of a methodology for planning the durability, as the capability for building components to keep, during time, the required performance levels. With this aim, the first phase of the Evaluation Method concerns the measurement of Service Life values in conventional reference conditions (Reference Service Life), input data in designing phases for a selective comparison among the different technical solutions belonging to the same class of technical elements. This input data has to be corrected by the designer in order to consider the real designing conditions, linked to use, maintenance and climatic agents and all those factors which can influence the appraisal of service life, important data for designing, management and planning of maintenance. First of all, the text reports the results of tests carried out for the appraisal of external not bearing walls’ Service Life in reference conditions for two different kind of technical solutions: the first with an interposed thermal insulation inside and the second with an external insulation. In the paragraphs it’s going to be presented the most relevant methodological developing results obtained by the research group about the prediction during the design phase of building components’ Service Life and Reliability, paying particular attention to Factorial Method, Performance Limits Method and Failure Modes, Effects and Criticality Analysis (FMECA).
