The Quality of ETICS in the Context of Energy and Social Changes (Case Study)

Abstract

The paper focuses on the quality of external composite ETICS (External Technical Insulation Composite System) façade systems from a long-term perspective in the context of energy and social changes and subsequent paths of housing construction, including reconstructions and renovations of prefabricated housing developments. These changes follow mainly from the EU energy concept and strategy in relation to housing and have an impact potential well beyond 2030. The aim of the paper is to show, based on field research and laboratory diagnostics on a selected reference sample of housing affected by biodegradation, to what extent the quality of ETICS façades is affected by technological aspects during the application of ETICS exterior plasters and during the implementation of photocatalytic coatings. The investigation shows that the influence of the human factor is one of the main aspects of negative impacts.
