Towards Nearly Zero-energy Buildings through Analyzing Reasons for Degradation of Facades

Nearly Zero-Energy Buildings offer one way to reduce energy use in the built environment and thus contribute to mitigating global climate change. This paper is focused on analyzing the reasons for degradation of External Insulation Composite system facades in order to develop sustainable and cost-effective solutions for dwelling stock renovation. While several reasons for degradation of the facades have been studied in depth, the impact of building technology and site management have received undeservedly little attention. This paper systemizes the factors affecting facade quality and proposes a research plan for on-site surveillance in order to measure the weight of different degradation factors.
