In mid-April, many innovative solutions and technologies were presented at the Fraunhofer joint booth during BAU 2023 in order to successfully continue on the path to climate neutrality.
Fraunhofer FEP presented several demonstrators of construction-related projects. A particular emphasis was placed on the topic of smart coatings for building envelopes. These solutions are attracting growing interest against the background of the increasing need for energy savings in the building sector.
Fraunhofer FEP is a partner in the EU project Switch2Save. Within this consortium, the deposition of electrochromic coatings on polymer films is one of the main topics. These coatings change their optical properties in response to an electrical signal given either by a person or by a building control system. Thanks to our project partner ChromoGenics we were in able to present such fully functional electrochromic laminates.
Such components are currently being installed in demo buildings in Sweden and Greece. Detailed pre- and post-monitoring of building operating parameters will provide insight into the effect of such retrofits in cold and warm climates, respectively.
Electrochromic coatings also play a crucial role in the federal funded FlexG 4.0 project, where the solution will be based on a development by Fraunhofer Institute for Silicate Research ISC. This project aims to include building monitoring into the educational content of various schools in the city of Dresden in Germany.
Another type of smart coatings are thermochromic materials. They change their properties depending on the temperature. As part of Switch2Save, Fraunhofer FEP has worked with the University of West Bohemia Pilzen to further develop the coating process. It is now available as a continuous deposition onto a roll of thin glass. Prototype windows are currently being tested in a model building in Greece. At the BAU trade show, our building model with a transparent thermochromic roof built from toy bricks delighted visitors young and old.
First analyses have shown that this application scenario could have a great effect in warm climates.
Flexible glass also served as a substrate for crystalline TiO2, one of the topics being addressed in the EU project NewSkin. Such developed hydrophilic coatings from the roll could serve for retrofitting facades and solar panels with ultra-thin glass in future. A first demonstrator for this result was also shown two weeks ago.
Thanks to all interested visitors, project partners and colleagues at the Fraunhofer joint booth! The many interesting discussions and exchanges will be taken into account in our future development work.
