At present, there is a high vacancy rate in office buildings due to people working remotely. This is a major economic and ecological problem: air-conditioned, illuminated office space stands empty while people work from home in less energy-efficient living spaces. For offices to be used, they must offer employees clear advantages. The classic multi-space concept, an open-plan office with various workplace modules, still leaves a lot to be desired, especially when it comes to privacy.

Acoustic panels are used to improve the acoustics in rooms with a high proportion of sound-reflecting surfaces. To make them look more attractive, the surface of these panels is covered with a slotted or micro-perforated wooden veneer. This regular surface design narrows the width of the absorption spectrum and impairs the high-quality, natural impression of the wood surface. In the present project, this technical problem is solved by a novel brushing process that opens the wood veneer along the grain, creating irregular holes.

In the GreenAcoustics project, a digital tool that takes a more comprehensive approach is to be designed and implemented as a prototype. The tool will be based on Fraunhofer IBP's existing reverberate technology, which uses not only the usual acoustic parameters, but also the shape of the room and the uneven distribution of absorbers in the room to calculate the reverberation time.

In the “Bassorber” project, a comprehensive calculation tool developed at IBP is used to accelerate and optimize the development of absorbers. The tool not only allows the absorption coefficients of almost all absorber structures to be optimized, but also the interaction between the absorbers.

In the Digital Room Acoustics Planning (DIGAKUST) project, a software solution is being developed that automatically calculates relevant key acoustic figures and makes them audible in a simulation environment in real time by transferring technical room parameters (e.g. size of the room, position of objects in the room, material properties of the surfaces). The aim is to provide users with an easy-to-use tool that captures interiors in great detail, automatically assigns object properties, allows the geometry of the room to be individually configured via an intuitive user interface, and makes it possible to experience the resulting changes in room acoustics in real time. Thus, the impact of structural or design changes on the overall acoustics becomes immediately apparent.

The CycloPlasma project combines an innovative adsorbent material and plasma technology to decontaminate wooden structures containing lindane and PCP. The CycloPlasma technique is a revolutionary concept when it comes to renovating and modernizing historical buildings. The method can be applied to all buildings in private and public ownership.

Psychoacoustics help to predict sound immission so that the actually perceived noise load can be mapped with a view to improving noise control.

In the project "Climate for Culture" the influence of climate change on cultural assets in Europe is determined with 27 partners.

In this project, the existing range of test facilities and simulation options at Fraunhofer IBP are supplemented in order to record rainwater retention capacity of green roofing structures.
