Components released from facade materials

Mathematical model predicts what is leached out of building facades by the rain

Research News /

The plaster and mortar used in facades often contain heavy metals and biocides that leach out and infiltrate into the soil when it rains. The Fraunhofer Institute for Building Physics IBP has created a model that combines measurements of the substances that leach out with regional meteorological data. This creates a precise forecast that can be used at the planning stage to determine the type and amount of substances that could be released from facade materials when it rains. This complex project was a collaborative effort alongside universities and numerous partners from industry.
