The estimated service life, as well as its components materials, is critical in order to establish realistic building maintenance programs, manageable and economically viable. The methods based on durability factors, proposed in ISO- 15686, are an efficient way of estimating the building’s service life. However, there has been limited information on quantifying the durability values, and their relationship to vulnerability or processes of deterioration which might present a constructive element. Then, this paper describes a method to characterize the most frequent damage mechanisms in the envelope of a building, since it is an element with a high risk of lesions and, accordingly, with a reduced durability. The system used to generate this information was the Delphi method that involves consultation to groups with expert-based approach to generate convergence of views. The results allow the identification and quantification of relevant durability factors that determine the occurrence of damage to an element affecting its service life.
