Buildings that produce more energy than they consume, thus serving as decentralized power generators providing electricity for the local infrastructure or for recharging electric vehicles. Building stock that can serve as a source of raw materials for urban production activities when it reaches the end of its useful life. And technology-assisted working environments designed for people instead of inflexible single-purpose structures. These are the visions for the city of the future that Fraunhofer IBP will be presenting at the UrbanTec exhibition and congress in Cologne from October 24 to 26.

As part of the joint Fraunhofer exhibit in Hall 7, Stand 029, IBP’s research scientists will present some of the innovative solutions they have developed as a response to the needs of tomorrow’s urban population, including noise abatement, smart energy supply concepts for metropolitan areas, and predictive software tools for environmental audits and the analysis of material and energy flows.
Alongside climate change and the depletion of natural resources, population growth and the increasing trend toward urbanization are the greatest challenges of the modern era. The United Nations Organization predicts that the number of city-dwellers will increase to 6.3 billion by the year 2050, almost twice as many as today. Various Fraunhofer Institutes have embarked on proactive research projects to address this issue, including Fraunhofer IBP, which plays a key role in the German government’s “Morgenstadt” lighthouse project, launched jointly with the Fraunhofer-Gesellschaft with the aim of developing innovative, sustainable solutions designed to optimize the human and environmental aspects of life in (tomorrow’s) cities and metropolitan areas. “The aim of our research is not to develop a vision for a better future but to transform that vision into real-life solutions. To do so, our researchers are following numerous lines of approach, which have the common denominator of being focused on the human aspect,” says the director of Fraunhofer IBP, Professor Klaus Sedlbauer.
Not all sources of noise are of a permanent nature. Building sites and open-air concerts are a temporary nuisance but nonetheless require effective measures to protect people living in the vicinity from the noise they create. An easy-to-use, flexible solution is provided by mobile noise barriers made of plastic materials. It would be wrong to assume that the light weight of the structures made of thin films and membranes makes them insufficient as noise protection. The solution consists of double-walled, inflatable elements of approximately the same dimensions of traditional noise barriers that are capable of blocking noise to a similar degree as a concrete wall. Using the simulation software developed by Fraunhofer IBP, the desired effect can be verified at the planning stage. Field trials have confirmed both the soundproofing effect and the ease with which the mobile system can be installed and transported from site to site.Future energy supplies
In addition to their work on various renewable power generation options, including photovoltaic systems, wind energy and biomass, the Fraunhofer scientists are consistently developing new control strategies. Through their model of an energy-efficient city, they aim to offer ideas for new approaches and initiate a process of dialog and knowledge-sharing. Pilot projects implemented by Fraunhofer IBP to demonstrate technologies for tomorrow’s energy-efficient cities are already underway in Stuttgart and Wolfhagen.On the way to a clean energy future
In a paper entitled “Buildings and Megacities”, Professor Klaus Sedlbauer will present his vision of the city of the future and the ways in which it might be implemented as part of the UrbanTec conference program on Wednesday October 26 at 9:45 a.m.Contacts for more information:

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
