Preventing mold formation and unwanted growth on façades
Mold growth represents a potential health hazard due to its production and spread of pathogenic substances. To avoid mold, it is important to develop prevention strategies that take into account both the preconditions for mold growth and the actual transient boundary conditions. WUFI® Bio is a bio-hygrothermal calculation method based on known climatic boundary conditions. It is used to assess the risk of mold formation and devise strategies that avoid its occurrence.
In contrast to the situation in building interiors, microbial growth on façades is usually a mere esthetic problem. The improved heat insulation of exterior components increases surface moisture and therefore the risk of algal and fungal growth. Fraunhofer IBP experts carry out chemical, biological and building physics research into ways of curbing and eliminating this growth.
