2014

In order to reach the sustainability of building interventions, the knowledge of the performance over time of materials and building components is necessary according to the new EU Regulation No. 305/2011, which introduced for construction works, the seventh requirement on their sustainability and particularly their durability. The paper wants to describe the instruments and methods to evaluate the durability of building components, used in the Laboratorio di Edilizia of the UniNetLab, the laboratory net of the University of Palermo.
