【 摘 要 】

With increasing number of thermally insulated buildings, the number of façade surfaces massively colonised by microorganisms is also rapidly growing. Such colonisation may occur even within a few years after the thermal insulation installation and evolve into a serious issue in a relatively short time. Perceived by the public as an aesthetic problem only, biofilms in fact represent rather significant technological and health risks. The aim of this case study is to show assessment and evaluation of the causes of biotic attack, including distinguishing between direct growth on the façade and mere pollution by surrounding spores. In addition, the impact of the façade biological colonisation on the building inner air microbial pollution was studied.
