It is essential to accelerate the necessary transformation process towards a sustainable energy supply. Pioneers of this modification process are the Fraunhofer Institutes for Building Physics IBP and for Wind Energy and Energy System Technology IWES, which will present their research work on the occasion of ISES Solar World Congress 2011 in Kassel at their common booth from August 28 to September 1, 2011.
The challenge is to cover future energy needs in Germany without any restrictions, if possible, and simultaneously to observe climatic goals. The supporting pillars of this process are the increase in applying regenerative energies and extensive measures for energy efficiency. The use of fossil energy sources to generate power and heat must be minimized and power from nuclear plants must be replaced.
Thus, the most essential components for the future energy system are energy efficiency in building as well as the integration of renewable energies and electro-mobility. This can be achieved by means of plus energy houses as well as smart buildings and supply structures. Innovative network control systems, decentralized energy management and modern storage technologies allow an increase in the share of renewable power generation.
This kind of profound modification offers opportunities: The energy transsion requires the development of new and the further development of already existing technologies to generate, store and transport energy. Fraunhofer scientists work on sophisticated solutions and complex technologies to manage the modification of energy supply. Therefore, research and development work is done in the field of innovative components for minimally invasive renovation, i.e. the profound retrofitting of a building without any greater annoyances for the residents, and economic and ecological concepts for cities on their way to »Smart City« into a future of sustainable and environmentally conscious energy use! One of the great challenges of modern times is lead urban centers into an ecologically sustainable future. To design and construct buildings and to live in them in a way that the impact on the environment is minimized requires great efforts in the field of building technology.
Scientific developments of building physics such as the zeroemission or the plus energy house are the basis for effective efficiency in building. Energy needs and CO2 emissions can most effectively reduced in cities by a nationwide renovation of buildings and an environmentally compatible energy supply. Sustainability and energy efficiency are the basic requirements for buildings and are essential in solving energy problems.
The building of the future generates more energy than it consumes. It is flexible and multi-functional, equipped by smart ventilation and lighting systems, and is made of recycled materials. It was built by preserving resources with a high degree of quality and precision, and can be totally recycled after the end-of-life.
In order to increase the share of renewable electricity generation in energy supply systems, most innovative technologies are developed and tested. These reach from the multi-functional PV module which, as standardized building component, can provide electricity, thermal insulation, climatization and other applications, to the operating system for the smart house which allows optimal utilization of renewables by automatic management of loads, generators and electric vehicle charging, and finally new electric networks which actively use the potentials of controlled loads, distributed generators and storages to assure a save, cost-effective and sustainable energy supply.
Especially important for mass market roll-out are standardized interfaces within the energy system, such that building blocks from different manufacturers can be combined in future smart grid systems. This is researched and demonstrated in the new »SysTec«, a unique experimenting facility to the south of Kassel to be officially opened in September. Scientific testing of free-field and roof PV systems, batteries and charging technology of electric vehicles, and new electricity grids will be focused upon there. The combination with additional technology, e.g. electricity storage by renewable methane, paves the way for an energy supply system based on renewable energy.
The energy transmission will be completed and the energy landscape will be primarily based on renewable energy sources in Germany until 2050. Then, 80 % of the energy supply will be produced by renewable energy sources, which make up 9,4 % at present!

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
