Methodological Framework to Assess the Significance of External Thermal Insulation Composite System (ETICS) on-site Activities

The façade system and each component of it need to meet specific technical performance criteria. The on-site construction process has the ability to modify technical performances with minor actions like mixing time, kneading water, insulation fixation, weather conditions, material moisture level and curing time. Minor deviations during construction can cause a variety of adverse consequences which lead to deterioration and reduced energy efficiency. The current paper proposes a methodology to rank the on-site degradation factors and provide a risk priority number. Based on the technical requirements set for building products, the significance of the collected degradation factors can be ranked by experts and the results ranked using a modified form of Failure Mode Effects Analysis (FMEA). The methodology provides a significance assessment tool to identify degradation factors in the construction phase.
