The water was four metres high in Christina’s house in Kreuzberg on the Ahr. After the flood, it was no longer habitable. Students and staff of the Department of Architecture wanted to change that. The Braunschweig initiative of the Institute for Sustainable Urbanism (ISU)<\/a> together with the Institute for Building Climatology and Energy of Architecture (IBEA)<\/a> started in November 2021 via the relief action “Potsdam hilft der Eifel”<\/a>. So far, the students have been able to make initial repairs to Christina’s house and prepare renovation work. Moisture-intensive measures have had enough time to dry, so that another eleven students have now been able to continue the repairs.<\/p>\n Since the last visit of the Braunschweig students, a lot has happened in Kreuzberg: the extension of Christina’s house can be used as a living space again, the kitchen and bathroom have been built in and a living room has been set up on the upper floor. The main house, however, is still in a shell state. So far, only the electrical installation could be provisionally repaired and the house prepared for the further renovation measures. The outside temperatures and drying times finally allowed the infill in the timber frame, which had been partially washed out and washed away by the flood, to be filled again with clay bricks and the walls to be plastered with loam.<\/p>\n Chistina's half-timbered house in Kreuzberg an der Ahr.

Finally, the wall heating could be installed on the exterior wall that had been insulated with expanded clay in November, and the intermediate ceiling was carefully repaired and plastered. On site, the measures were also supported by another knowledgeable expert, Stefan Funkenberg, from the Eifel-based company Claytec, which also provided the project with a large part of the building material free of charge.<\/p>\n The architecture students not only provided active support, but also got to grips with various tools and measuring instruments as well as with loam as a building material. They learned how to mix the right proportions of clay straw, water and other loam mixtures for different types of loam rendering and loam adhesive. Thanks to the help of the people of Braunschweig, Christina’s house will soon be completely ready for occupancy again.<\/p>\n More information<\/strong> can be found on the website www.potsdam-hilft-der-eifel.de<\/a> and www.sustainableurbanism.org<\/a>.<\/p>\n The teams include:<\/strong><\/p>\n Prof. Dr. Vanessa Carlow with Chantal Karadag, Olaf Mumm, Sebastian Schmidt and ISU Team<\/p>\n Prof. Elisabeth Endres with Tobias P\u00f6rschke and IBEA Team<\/p>\n <\/p>\n Note: The team has agreed on a 2G-Plus arrangement for the collaboration.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":" Three quarters of a year after the flood disaster, the … <\/p>\n","protected":false},"author":44,"featured_media":48760,"comment_status":"closed","ping_status":"closed","template":"","format":"standard","class_list":["post-49144","kb_magazin","type-kb_magazin","status-publish","format-standard","has-post-thumbnail","hentry","kb_cat_magazin-study-and-teaching","kb_tags-architecture","kb_tags-civil-engineering","kb_tags-engagement-en","kb_tags-future-city","kb_tags-study","kb_tags-transfer-en"],"acf":[],"yoast_head":"\nMain house still under construction<\/h3>\n
