Fraunhofer Institute for Microstructure of Materials and Systems IMWSEnvironmental simulation is a method used at Fraunhofer IMWS to replicate certain processes of the natural environment in a controlled room. Various elements can be integrated, such as a sun simulation to replicate sunlight or a climate chamber to control temperature, humidity, and air currents. This makes it possible to carry out specific tests, experiments, or studies under controlled conditions in order to investigate, for example, the effects of environmental factors on materials, components, or products.
