Cylindrical granules for the production of sound-absorbing model substances.
If the acoustic design of the microstructure of granular sound absorbers is carried out specifically, more efficient materials than usual can be constructed.

Winter night with a temperature of -15°C.
The Hygrothermics Department carried out a serviceability check for an innovative facade construction in Ankara.
more infoFig. 1: Water infiltrating a wall after simulation of water damage.
The laboratories and the knowledge of the Fraunhofer IBP regarding building drying offer the possibility to test the drying and component variations.
more infoHygrothermal behavior of typical components using the new reference year (red line) as compared to multi-year measurements at different locations within the observed climate region.
The aim of the project is to create a resilient and reliable climate data basis for component simulation.
more infoAir permeability tests on a cleanroom ceiling. The ceiling panels are installed in the test box and connected to the test bench.
On behalf of industry, the air-tightness of suspended ceiling constructions especially for clean rooms was investigated for the first time.
more infoPrototype paving stones as green bodies - straight after the molding process at the factory.
In the project, a water reservoir is integrated into a paving stone, which transports water at high temperatures to the surface and cools it down.
more infoWith the help of hygrothermal simulations, it is possible to predict long-term moisture conditions in inverted roof insulation under known conditions.
more infoInfiltration of water from above into a tiled section of an aerated concrete wall.
The results show large differences in the drying behaviour of masonry blocks. The biggest effect on drying is the application of plaster.
more infoThe cloud system of the indoor climate analysis platform VALEA.
The scientists of the Department of Hygrothermics developed a methodology that evaluates the measured indoor climate and protects the user as well as the building fabric from damage.
more infoSimulated moisture content in the timber frame of a flat roof in Chemnitz over a period of 8 years, based on real measurement data (violet), the average year (green), and a combination of three average years, two critical years (red band) and three further average years (blue).
In the project, the Fraunhofer IBP created new hygrothermal reference years that represent temperature, radiation, humidity and precipitation.
