The purpose of this research is to assess and quantify the environmental effects on cement-rendered facades in real-life service conditions. A holistic approach is proposed based on the assessment of the visual impact of the actual climatic environment that affects the aesthetic performance and durability of 19 cement-rendered facades located in Lisbon. Portugal. Different degradation indicators are presented and a deterioration path is identified, which points out to the possibility of modeling the overall degradation of facades in similar building and environmental conditions. Although the proposed method reflects the Portuguese building context, it can be easily adapted to other countries and expanded to include various cladding solutions, so that their remaining service life can be integrated in the existing commercial methodologies for service life prediction and asset management.
