Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed façade elements where the building’s heating, ventilation and sanitation systems are integrated into the thermal insulation panels of the building envelope.
The multi-functional insulation boards and window elements can be implemented in new buildings as well as buildings undergoing renovation. The type of materials used and the integration technique can be combined according to the customer’s wishes. The prefabricated façade and window elements are the first results stemming from several research projects in which Fraunhofer ISE is involved.

It has been shown that the use of these elements increases the building’s energy efficiency.
Reducing energy consumption and boosting energy efficiency are important prerequisites to achieve a climate neutral building stock, the aim of the German federal government by 2050. The political ambitions are high, yet the current renovation rate is very low. Flexible and cost-effective solutions are lacking. Together with industry partners the experts at Fraunhofer ISE have been working on developments over the past years to combine the renovation of the building envelope with the optimization of the HVAC systems.
Now they present their first prefabricated element developed within the project “Retrokit” (http://www.ise.fraunhofer.de/en/business-areas/solar-thermal-technology/research...). The element consists of multi-functional insulation boards and prefabricated window elements. The construction allows different materials to be combined together. “Depending on the fire safety regulations, insulation materials such as foam or mineral wool can be combined with ventilation ducts made of plastic or metal,” explains Fabien Coydon of Fraunhofer ISE.
The technical components of ventilation, heating, sanitation pipes or electrical and ICT wiring can be integrated in the thermal panels. These façade elements are especially suitable for existing and older buildings. Their use will soon be demonstrated for the first time in a building from the 1950s in Frankfurt, Germany.
One of the biggest advantages of these multi-functional façade elements is that they are installed outside on the façade. Therefore, the inhabitants experience less disrupted during renovation. Also, the installation time required is reduced. To install the element, the window elements are first mounted onto the façade and subsequently a first layer of insulation with integrated channels.
The ducts or pipes for the building technology services and the sanitation system are then installed using a simple click system. Afterwards a second layer of insulation is installed and the exterior plaster is applied. Finally the old windows are removed from inside. “We see here a large potential because the concept and installation procedure enable a fast, cost-effective and high quality renovation,” says Coydon.
“And the need is high, since residential buildings from the post-war era through to the 80s urgently require an energy retrofit to meet today’s standards.” The multi-functional façades, the prefabricated window elements and the entire renovation concept developed by Fraunhofer ISE are protected by patents. Product marketing is possible through licensing contracts.
Meet our experts at the ISH in Frankfurt from the 10th -14th March 2015 in Hall 10.3, Booth C79!

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
