Predict the amount of copper runoff from roofs and facades.

The model helps you to make conservative predictions of the total annual amount of copper runoff from copper sheet and copper-tin (bronze) alloys used for roofing and facades in architectural applications. Copper runoff from copper-zinc alloys materials can also be roughly predicted by multiplying the result with 0.6.

Activities of the IO group in atmospheric corrosion

For more than two decades the team has performed world-leading field- and laboratory investigations on atmospheric corrosion of metals and alloys used in outdoor and architectural applications and on the environmental interaction and fate of metals dispersed from such surfaces.

The approach involves multi-analytical and interdisciplinary studies to assess corrosion and surface phenomena and mechanisms, and their relation to metal dispersion, bioaccessibility, bioavailability, metal speciation and toxicity.

While focusing on fundamental questions, the research is applied and strongly related to societal and industrial issues and run in close collaboration with national and international industry, stakeholders and industrial organizations. On-going research activities further have strong implications for regulation and the classification system of chemicals within the European Union, REACH, as well as for standardization, environmental risk assessment and risk management of metals and alloys.

The Runoff Process

Metal runoff is the fraction of oxidized metals within the patina that by the action of rainwater can be released from a metal or metal alloy surface.
Learn about the Runoff Process

Patina Evolution

The appearance and barrier properties of the patina change with time and are strongly dependent on prevailing environmental conditions.
Learn about the Patina Evolution

Environmental Fate

Released copper rapidly changes its chemical speciation and bioavailability upon environmental interaction.
